High Reliability R-10 Windows Using Vacuum Insulating Glass Units  

SciTech Connect

The objective of this effort was for EverSealed Windows (“EverSealed” or “ESW”) to design, assemble, thermally and environmentally test and demonstrate a Vacuum Insulating Glass Unit (“VIGU” or “VIG”) that would enable a whole window to meet or exceed the an R-10 insulating value (U-factor ? 0.1). To produce a VIGU that could withstand any North American environment, ESW believed it needed to design, produce and use a flexible edge seal system. This is because a rigid edge seal, used by all other know VIG producers and developers, limits the size and/or thermal environment of the VIG to where the unit is not practical for typical IG sizes and cannot withstand severe outdoor environments. The rigid-sealed VIG’s use would be limited to mild climates where it would not have a reasonable economic payback when compared to traditional double-pane or triple-pane IGs. ESW’s goals, in addition to achieving a sufficiently high R-value to enable a whole window to achieve R-10, included creating a VIG design that could be produced for a cost equal to or lower than a traditional triple-pane IG (low-e, argon filled). ESW achieved these goals. EverSealed produced, tested and demonstrated a flexible edge-seal VIG that had an R-13 insulating value and the edge-seal system durability to operate reliably for at least 40 years in the harshest climates of North America.

Cellular glass insulation keeps liquefied gas from vaporizing  

SciTech Connect

The North West Shelf Project, located on the Burrup Peninsula in Western Australia, supplies much of that vast state with natural gas for domestic and industrial applications. Some of the gas is also exported to Japan as liquefied natural gas (LNG). While awaiting shipment to Japan, the LNG is stored at {minus}322 F in four storage tanks, each with a capacity of 2.5 million ft{sup 3}. When Woodside Offshore Petroleum Pty Ltd., operator of the LNG facility, selected insulation material for the storage tanks, it went in search of a material with more than just insulating value. Since the insulation is installed inside the tanks, it must be able to resist wicking or absorbing the LNG. Also, it had to have sufficient strength to withstand the weight of the 2.5 million ft{sup 3} of LNG without being crushed or losing its insulting properties. And, as a safety precaution, the selected materials should neither burn nor support combustion. Ultimately, Woodside selected a cellular glass insulation called Foamglas, from Pittsburgh Corning Corp., that met all the performance criteria and was cost competitive with the lesser-performing alternatives. Foamglas is produced from strong, inert borosilicate glass. Its insulating capability is provided by the tiny, closed cells of air encapsulated within the foam-like structure of the glass. Since the cells are closed,neither liquid nor vapor can enter the structure of the insulation. The inert glass itself will not absorb or react with LNG, nor will it burn or support a fire. The cellular structure provides effective insulation in both not and cold applications, and offers a fire barrier.

Heat insulation solar glass and application on energy efficiency buildings  

Science Journals Connector (OSTI)

Abstract Building integrated photovoltaics are among the best methods for generating power using solar energy. To promote and respond to the concept of BIPVs, this study developed a type of multi-functional heat insulation solar glass (HISG) that differs from traditional transparent PV modules, providing functions such as heat insulation and self-cleaning in addition to power generation. This study also made thorough preparations for the safety of future HISG installation on curtain walls in large-scale buildings. Furthermore, this study provides a comprehensive discussion regarding the energy-saving performance of HISG and relevant practical applications. Two experimental houses were constructed, which independently employed HISG and single-layer tempered glass. Taiwan's climate was adopted as the environmental condition for the experiment, and the effects of HISG and single-layer tempered glass on indoor temperature variation and the energy consumed by air conditioners and heaters were explored. Related software was also employed to simulate, compare, and verify HISG efficacy.

SUPERGLASS. Engineering field tests - Phase 3. Production, market planning, and product evaluation for a high-thermal-performance insulating glass design utilizing HEAT MIRROR transparent insulation. Final report  

SciTech Connect

HEAT MIRROR transparent window insulation consists of a clear polyester film two mils (.002'') thick with a thin, clear low-emissivity (.15) coating deposited on one side by state-of-the-art vacuum deposition processes. This neutral-colored invisible coating reflects long-wave infrared energy (heat). When mounted by being stretched with a 1/2'' air-gap on each side of the film, the resulting unit reduces heat loss by 60% compared to dual insulating glass. Southwall Corporation produces HEAT MIRROR transparent insulation and markets it to manufacturers of sealed insulating glass (I.G.) units and window and building manufacturers who make their own I.G. These companies build and sell the SUPERGLASS sealed glazing units. Units made and installed in buildings by six customers were visited. These units were located in many geographic regions, including the Pacific Northwest, Rocky Mountains, New England, Southeast, and West Coast. As much as could be obtained of their history was recorded, as was their current condition and performance. These units had been in place from two weeks to over a year. All of the units were performing thermally very well, as measured by taking temperature profiles through them and through adjacent conventional I.G. units. Some units had minor visual defects (attributed to I.G. assembly techniques) which are discussed in detail. Overall occupant acceptance was enthusiastically positive. In addition to saving energy, without compromise of optical quality or appearance, the product makes rooms with large glazing areas comfortable to be in in cold weather. All defects observed were present when built; there appears to be no in-field degradation of quality at this time.

Investigation of single unit flashovers in HVDC insulator strings  

SciTech Connect

In HVDC transmission lines, a special phenomenon, so called single unit flashover, is observed under some special conditions. Only one or two insulator units repeat flashovers, not resulting in an overall flashover along the string. However, higher magnitudes of audible noise, radio and television interferences, may give a serious problem. Based on the investigation on {+-}500-kV full scale insulator strings, higher occurrence probability of single unit flashovers under cold-wet-switch-on conditions was clarified compared with normal continuous operating voltage conditions. Effectiveness of the newly proposed countermeasures to prevent single unit flashovers was demonstrated by experiments in laboratory and in field.

Development of New Generation of Thermally-Enhanced Fiber Glass Insulation  

SciTech Connect

This report presents experimental and numerical results from thermal performance studies. The purpose of this Cooperative Research and Development Agreement (CRADA) between UT-Battelle, LLC and John s Manville was to design a basic concept of a new generation of thermally-enhanced fiber glass insulation. Different types of Phase Change Materials (PCMs) have been tested as dynamic components in buildings during the last 4 decades. Most historical studies have found that PCMs enhance building energy performance. Some PCM-enhanced building materials, like PCM-gypsum boards or PCM-impregnated concretes have already found their limited applications in different countries. Today, continued improvements in building envelope technologies suggest that throughout Southern and Central U.S. climates, residences may soon be routinely constructed with PCM in order to maximize insulation effectiveness and maintain low heating and cooling loads. The proposed thermally-enhanced fiber glass insulation will maximize this integration by utilizing a highly-efficient building envelope with high-R thermal insulation, active thermal mass and superior air-tightness. Improved thermal resistance will come from modifications in infrared internal characteristics of the fiber glass insulation. Thermal mass effect can be provided by proprietary thermally-active microencapsulated phase change material (PCM). Work carried out at the Oak Ridge National Laboratory (ORNL) on the CRADA is described in this report.

Removable fibrous glass insulation fitted to complex equipment shapes results in $178,000/yr savings  

SciTech Connect

In early 1980, PPG Industries embarked on a general plant energy conservation effort at its Lake Charles, LA plant where chlor-alkalis, various chlorinated hydrocarbons, and vinyl chloride monomer are manufactured. Company engineers sought a means of insulating process steam components that, because of their complex shapes, were not (and normally are not) insulated. These components included flanges on heat exchanger heads and reboilers, steam valves in process areas, manways and other equipment. PPG plant engineers specified removable, reusable blanket insulation. The blankets are constructed of a fibrous glass mat form insulation encased in a silicone-impregnated glass cloth or similar weather barrier. Each insulation blanket was custom-made for its particular equipment shape and service application to ensure a close fit and optimal energy efficiency. Insulation thickness, type of weather barrier, and mesh were specified according to intended use. For protection from abrasion or puncture, some of the blankets also were covered with stainless steel, Monel, or Inconel wire mesh. Overall, the blankets provide high strength, durability, low thermal conductivity ratings, and an operating range of up to 1200/sup 0/F. Reduced maintenance costs and improved worker productivity have been evidenced since installing the blanket insulation. Further, PPG has increased energy efficiency. Project savings were tracked for 30 months (insulation and installation costs vs. fuel and maintenance savings) and revealed annual plant savings of $178,000-$130,000 in energy savings and $48,000 in maintenance savings. With the cost of the insulation blankets being about $125,000, PPG recovered its investment in under a year.

Cryogenic sandwich-type insulation board composed of E-glass/epoxy composite and polymeric foams  

Science Journals Connector (OSTI)

Liquefied natural gas (LNG) is a clean energy source whose consumption has recently increased greatly due to the failure of a nuclear power plant. LNG is transported with LNG carriers that store LNG at the cryogenic temperature of ?163 °C. Because the cargo containment system (CCS) of LNG carriers should be operated for more than 40 years at the cryogenic temperature, its reliability against thermal and mechanical loads should be guaranteed without compromising its thermal insulation performance. For reasons of both mechanical and thermal performance, the faces and cores of conventional insulation boards are made of plywood and high-density (110 kg/m3) polymeric. In this study, an advanced sandwich-type insulation board composed of E-glass/epoxy composite faces and a low-density polymeric foam core with a composite box configuration was developed to seal a foam blowing gas of low thermal conductivity. The mechanical performance of the advanced sandwich-type insulation board was simulated using the finite element analysis (FEA) software ABAQUS (SIMULIA, USA). The sealing performance of the composite box was also investigated experimentally. Finally, the thermal performance of the advanced sandwich-type insulation board was numerically investigated using thermal conductivity equations.

Theoretical and Experimental Thermal Performance Analysis of Building Shell Components Containing Blown Fiber Glass Insulation Enhanced with Phase Change Material (PCM)  

SciTech Connect

Different types of Phase Change Materials (PCMs) have been tested as dynamic components in buildings during the last 4 decades. Most historical studies have found that PCMs enhance building energy performance. Some PCM-enhanced building materials, like PCM-gypsum boards or PCM-impregnated concretes have already found their limited applications in different countries. Today, continued improvements in building envelope technologies suggest that throughout Southern and Central US climates, residences may soon be routinely constructed with PCM in order to maximize insulation effectiveness and maintain low heating and cooling loads. The proposed paper presents experimental and numerical results from thermal performance studies. These studies focus on blown fiber glass insulation modified with a novel spray-applied microencapsulated PCM. Experimental results are reported for both laboratory-scale and full-size building elements tested in the field. In order to confirm theoretical predictions, PCM enhanced fiber glass insulation was evaluated in a guarded hot box facility to demonstrate heat flow reductions when one side of a test wall is subjected to a temperature increase. The laboratory work showed reductions in heat flow of 30% due to the presence of approximately 20 wt % PCM in the insulation. Field testing of residential attics insulated with blown fiber glass and PCM was completed in Oak Ridge, Tennessee. Experimental work was followed by detailed whole building EnergyPlus simulations in order to generate energy performance data for different US climates. In addition, a series of numerical simulations and field experiments demonstrated a potential for application of a novel PCM fiber glass insulation as enabling technology to be utilized during the attic thermal renovations.

Filament-strung stand-off elements for maintaining pane separation in vacuum insulating glazing units  

DOE Patents (OSTI)

A vacuum insulating glazing unit (VIGU) comprises first and second panes of transparent material, first and second anchors, a plurality of filaments, a plurality of stand-off elements, and seals. The first and second panes of transparent material have edges and inner and outer faces, are disposed with their inner faces substantially opposing one another, and are separated by a gap having a predetermined height. The first and second anchors are disposed at opposite edges of one pane of the VIGU. Each filament is attached at one end to the first anchor and at the other end to the second anchor, and the filaments are collectively disposed between the panes substantially parallel to one another. The stand-off elements are affixed to each filament at predetermined positions along the filament, and have a height substantially equal to the predetermined height of the gap such that the each stand-off element touches the inner surfaces of both panes. The seals are disposed about the edges of the panes, enclosing the stand-off elements within a volume between the panes from which the atmosphere may be evacuated to form a partial vacuum.

Arasteh, and Dragan C. Curcija Journal Energy and Buildings Volume 54 Issue November 2012 Pagination 453-460 Date Published 11/2012 Keywords concave, convex, deflection, field test, gap, insulating glass unit, thermal performance, thermal transmittance, u-factor Abstract This study examines the thermal performance impact of center-of-glass (COG) deflections in double- and triple-pane insulating glass units (IGUs) installed at several locations throughout the US. Deflection was measured during summer and winter temperatures; the results show that outdoor temperature variations can be represented a linear change in COG gap width in double- and triple-pane IGUs within the temperature ranges measured. However, the summer-winter temperature-induced deflection is similar in magnitude to the observed spread in COG deflection of similar units at the same temperature, which suggests that factors other than temperature are of equal importance in determining the in-situ deflection of windows. The effect of deflection on thermal performance depends on the IGU's designed gap. Units constructed with smaller-than-optimal gaps often exhibit significant U-factor change due to temperature-induced reduction in gap width. This effect is particularly problematic in high-performance triple glazing where small gap dimension changes can have a large impact on performance.

Improved compact insulation panel is provided which is comprised of two adjacent metal sheets spaced close together with a plurality of spherical, or other discretely shaped, glass or ceramic beads optimally positioned between the sheets to provide support and maintain the spacing between the metal sheets when the gases there between are evacuated to form a vacuum. These spherical glass beads provide the maximum support while minimizing thermal conductance. In its preferred embodiment; these two metal sheets are textured with ribs or concave protrusions in conjunction with the glass beads to maximize the structural integrity of the panels while increasing the spacing between beads, thereby reducing the number of beads and the number of thermal conduction paths. Glass or porcelain-enameled liners in combination with the glass spacers and metal sidewalls effectively decrease thermal conductivity, and various laminates, including wood, porcelain-enameled metal, and others effectively increase the strength and insulation capabilities of the panels. Also, a metal web is provided to hold the spacers in place, and strategic grooves are shown to accommodate expansion and contraction or shaping of the panels. 35 figs.

Insulation products promote thermal efficiency  

SciTech Connect

The judicious use of thermal insulation products in non-residential buildings can provide a number of advantages including increased energy efficiency, lower first costs (by avoiding overside HVAC systems), improved fire safety and better acoustics. Thermal insulation products are those products which retard the flow of heat energy. Materials include glass, plastics, and organic materials such as wood fibers, vermiculite and perlite. Forms range from the familiar batts and blankets of glass fibers to foamed plastic, rigid boards, losse fill and systems combining two or more products, such as polystyrene boards covered with insulating plaster. The R values of selected insulation materials with a cost/sq. ft. of each material at R 10 are given. Costs cover both the material and installation and may vary depending on local conditions.

Compact vacuum insulation  

DOE Patents (OSTI)

An ultra-thin compact vacuum insulation panel is comprised of two hard, but bendable metal wall sheets closely spaced apart from each other and welded around the edges to enclose a vacuum chamber. Glass or ceramic spacers hold the wall sheets apart. The spacers can be discrete spherical beads or monolithic sheets of glass or ceramic webs with nodules protruding therefrom to form essentially "point" or "line" contacts with the metal wall sheets. In the case of monolithic spacers that form "line" contacts, two such spacers with the line contacts running perpendicular to each other form effectively "point" contacts at the intersections. Corrugations accommodate bending and expansion, tubular insulated pipes and conduits, and preferred applications are also included.

Highly Insulating Window Technology  

NLE Websites -- All DOE Office Websites (Extended Search)

Window Technology Window Technology Temperature differentials across a window, particularly with cold exterior environments in residential buildings, can lead to significant energy losses. Currently available low-emissivity coatings, gas-fills, and insulating frames provide significant energy savings over typical single or double glazed products. The EWC website provides information on how double glazed low-e gas-filled windows work as well as information on commercially available superwindows (three layer, multiple low-e coatings, high performance gas-fills). The next generation of highly insulating window systems will benefit from incremental improvements being made to current components (i.e. more insulating spacers and frame materials/designs, low-e coatings with improved performance properties). LBNL uses its experimental facilities and software tools to collaborate with window and glass industry representatives to better understand the impacts of new components on overall product performance.

Vacuum Glazing; A Thermally Insulating Window Technology  

NLE Websites -- All DOE Office Websites (Extended Search)

Vacuum Glazing; A Thermally Insulating Window Technology Vacuum Glazing; A Thermally Insulating Window Technology Speaker(s): Cenk Kocer Date: May 31, 2012 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Sunnie Lim The vacuum glazing consists of two panes of glass separated by a sub-millimetre vacuum gap. Under the action of atmospheric pressure the separation of the panes is maintained by an array of high strength spacers in the gap. The glass panes are hermetically sealed at the edge using a low melting point glass frit (solder glass). Since 1913 many have worked on a practical implementation of such a flat insulating glass structure, with success finally being reported in 1989 by Collins et al. at the University of Sydney. The purpose of this talk is to present a brief history of the vacuum glazing research at the University of Sydney, and outline in detail

Chapter Three - Material Selection for Thermal Insulation  

Science Journals Connector (OSTI)

Abstract This chapter covers the minimum requirements and fundamental concepts relating to the composition, size, dimensions, physical properties, inspection, packaging, and marking of a wide range of thermal insulations for use on pipe and equipment surfaces such as mineral wool insulation, rigid and semi-rigid mineral fiber block and board thermal insulation, mineral blanket and blanket-type pipe insulation, calcium silicate preformed block and pipe section thermal insulation, cellular glass, baked cork, and rigid cellular polyurethane and polyisocyanurate and filler insulation. In addition, vapor barriers, joint sealants, adhesive materials, metallic jacketing, and accessory materials are reviewed. For satisfactory performance, properly installed protective vapor barriers have to be used in low-temperature applications to prevent movement of moisture through or around the insulation towards the colder surface.

Frequency-dependent conductivity of electron glasses  

Science Journals Connector (OSTI)

Results of dc and frequency-dependent conductivity in the quantum limit—i.e., ??>kBT—for a broad range of dopant concentrations in nominally uncompensated, crystalline phosphorous-doped silicon and amorphous niobium-silicon alloys are reported. These materials fall under the general category of disordered insulating systems, which are referred to as electron glasses. Using microwave resonant cavities and quasioptical millimeter-wave spectroscopy we are able to study the frequency-dependent response on the insulating side of the metal-insulator transition. We identify a quantum critical regime, a Fermi glass regime, and a Coulomb glass regime. Our phenomenological results lead to a phase diagram description, or taxonomy, of the electrodynamic response of electron glass systems.

An electrostatic linear accelerator includes an electrode stack comprised of primary electrodes formed or Kovar and supported by annular glass insulators having the same thermal expansion rate as the electrodes. Each glass insulator is provided with a pair of fused-in Kovar ring inserts which are bonded to the electrodes. Each electrode is designed to define a concavo-convex particle trap so that secondary charged particles generated within the accelerated beam area cannot reach the inner surface of an insulator. Each insulator has a generated inner surface profile which is so configured that the electrical field at this surface contains no significant tangential component. A spark gap trigger assembly is provided, which energizes spark gaps protecting the electrodes affected by over voltage to prevent excessive energy dissipation in the electrode stack.

The quantum Biroli-Mézard model: glass transition and superfluidity in a quantum lattice glass model  

E-Print Network (OSTI)

We study the quantum version of a lattice model whose classical counterpart captures the physics of structural glasses. We discuss the role of quantum fluctuations in such systems and in particular their interplay with the amorphous order developed in the glass phase. We show that quantum fluctuations might facilitate the formation of the glass at low enough temperature. We also show that the glass transition becomes a first-order transition between a superfluid and an insulating glass at very low temperature, and is therefore accompanied by phase coexistence between superfluid and glassy regions.

Superconductor-insulator Transition in La2-xSrxCuO4 at the Pair Quantum Resistance  

SciTech Connect

High-temperature superconductivity in copper oxides arises when a parent insulator compound is doped beyond some critical concentration; what exactly happens at this superconductor-insulator transition is a key open question. The cleanest approach is to tune the carrier density using the electric field effect; for example, it was learned in this way that weak electron localization transforms superconducting SrTiO{sub 3} into a Fermi-glass insulator. But in the copper oxides this has been a long-standing technical challenge, because perfect ultrathin films and huge local fields (>10{sup 9} Vm{sup -1}) are needed. Recently, such fields have been obtained using electrolytes or ionic liquids in the electric double-layer transistor configuration. Here we report synthesis of epitaxial films of La{sub 2-x}Sr{sub x}CuO{sub 4} that are one unit cell thick, and fabrication of double-layer transistors. Very large fields and induced changes in surface carrier density enable shifts in the critical temperature by up to 30 K. Hundreds of resistance versus temperature and carrier density curves were recorded and shown to collapse onto a single function, as predicted for a two-dimensional superconductor-insulator transition. The observed critical resistance is precisely the quantum resistance for pairs, R{sub Q} = h/(2e) = 6.45 k{Omega}, suggestive of a phase transition driven by quantum phase fluctuations, and Cooper pair (de)localization.

Topological insulators and superconductors  

Science Journals Connector (OSTI)

Topological insulators are new states of quantum matter which cannot be adiabatically connected to conventional insulators and semiconductors. They are characterized by a full insulating gap in the bulk and gapless edge or surface states which are protected by time-reversal symmetry. These topological materials have been theoretically predicted and experimentally observed in a variety of systems, including HgTe quantum wells, BiSb alloys, and Bi2Te3 and Bi2Se3 crystals. Theoretical models, materials properties, and experimental results on two-dimensional and three-dimensional topological insulators are reviewed, and both the topological band theory and the topological field theory are discussed. Topological superconductors have a full pairing gap in the bulk and gapless surface states consisting of Majorana fermions. The theory of topological superconductors is reviewed, in close analogy to the theory of topological insulators.

Chapter 9 - Pipeline Insulation  

Science Journals Connector (OSTI)

Oilfield pipelines are insulated mainly to conserve heat. The need to keep the product in the pipeline at a temperature higher than the ambient could exist for the following reasons: preventing the formation of gas hydrates, preventing the formation of wax or asphaltenes, enhancing the product flow properties, increasing the cooldown time after shutting down, and meeting other operational/process equipment requirements. On the other hand, in liquefied gas pipelines, such as LNG, insulation is required to maintain the cold temperature of the gas to keep it in a liquid state. This chapter describes the commonly used insulation materials, insulation finish on pipes, and general requirements for insulation of offshore and deepwater pipelines.

Identifying the Bose glass phase  

E-Print Network (OSTI)

Introducing disorder into the Bose-Hubbard model at integer fillings leads to a Bose glass phase, along with the Mott insulator and superfluid phases. We suggest a new order parameter: the determinant of the one body density matrix, which is nonzero only within the Mott-insulator phase. Alongside the superfluid fraction, it is then possible to distinguish the three phases. The Bose glass phase is the only phase which has vanishing determinant and superfluid fraction. The vanishing of the determinant in the Bose glass phase occurs due to the partial fragmentation of the condensate into localized fragments, each with zero superfluid response, which implies the presence of unoccupied sites and hence the presence of lines of zeros in the one body density matrix. In the superfluid phase, the determinant vanish for another reason - due to the macroscopic occupation of a single particle state. Finally, we suggest the enhancement of the three body decay rate in the Bose glass phase, as an experimental indicator for the presence of localized fragments.

Finite element analysis of substation composite insulators  

Science Journals Connector (OSTI)

Composite insulators are rapidly replacing their porcelain counterparts in electrical substation applications. These insulators consist of a glass-reinforced polymer (GRP) rod, with two metal end fittings radially crimped onto the ends of the rod during assembly. In this paper, axisymmetric finite element models are developed to evaluate the mechanical performance of composite insulators under externally applied axial compression. The analyses are performed by assuming both a perfectly bonded interface between the composite rod and the end fittings, and an imperfect interface which permits large relative sliding with Coulomb friction. Results indicate that the perfect interface model is unrealistic since it predicts singular stresses at the interface comer and an overall linear structural response. On the other hand, the imperfect interface model is found to simulate accurately the structural non-linearity caused by relative sliding of the GRP rod within the end fittings. The imperfect interface model has therefore been used to evaluate the effects of interface friction, and the extent of crimping, on the maximum load-bearing capacity of substation composite insulators.

Electricity bills, oil bills, gas bills - all homeowners pay for one or more of these utilities, and wish they paid less. Often many of us do not really know how to control or reduce our utility bills. We resign ourselves to high bills because we think that is the price we have to pay for a comfortable home. We encourage our children to turn off the lights and appliances, but may not recognize the benefits of insulating the attic. This publication provides facts relative to home insulation. It discusses where to insulate, what products to use, the decision making process, installation options, and sources of additional information.

Constraints on topological order in Mott Insulators  

E-Print Network (OSTI)

We point out certain symmetry induced constraints on topological order in Mott Insulators (quantum magnets with an odd number of spin $\\tfrac{1}{2}$ per unit cell). We show, for example, that the double semion topological order is incompatible with time reversal and translation symmetry in Mott insulators. This sharpens the Hastings-Oshikawa-Lieb-Schultz-Mattis theorem for 2D quantum magnets, which guarantees that a fully symmetric gapped Mott insulator must be topologically ordered, but is silent on which topological order is permitted. An application of our result is the Kagome lattice quantum antiferromagnet where recent numerical calculations of entanglement entropy indicate a ground state compatible with either toric code or double semion topological order. Our result rules out the latter possibility.

Coated glass in the automotive industry  

Science Journals Connector (OSTI)

Inorganic coatings on glasses have reached the level where they will certainly be applied in the automotive industry in order to solve such glazing problems as heat load, heat loss, glare, UV adsorption, disturbed reflections, electromagnetic influence and thermal insulation. Their widespread use will depend on optimising the solution to problems of solar control and heatable glasses while the glass is also capable of the other functions required of it, thus justifying the relatively high cost that is predicted. There remain unsolved problems in optical limits and colour matching. When these are solved solar control glasses are likely to give real advantages in terms of air conditioning and comfort, and heatable glasses will be used in association with electrical power for demisting and deicing. Particular attention is being directed to a class of infrared reflecting and heatable glasses, obtained by selectively coating transparent plastic films that are embedded or bonded in laminated or tempered glasses. Fabricating this type of glasses has mainly been useful for two reasons: (I) to develop versatile techniques to make solar control IR reflecting and heatable glasses for all kinds and dimensions of vehicle glazing; and (2) to assess whether these glasses are really feasible alternatives to directly coated glasses. This paper describes results of some solar control experiments in Fiat cars: to ascertain the actual internal temperature differences found when glazing vehicles with the absorbing and reflecting IR glasses currently available; and to obtain results with a similar purpose using heatable glasses. There is also discussion of how the glasses could be used in glazing all or parts of a car's windows / especially addressing problems of glare. Suggestions are made of the directions of this research in the future.

Cooper Pairs in Insulators?!  

ScienceCinema (OSTI)

Nearly 50 years elapsed between the discovery of superconductivity and the emergence of the microscopic theory describing this zero resistance state. The explanation required a novel phase of matter in which conduction electrons joined in weakly bound pairs and condensed with other pairs into a single quantum state. Surprisingly, this Cooper pair formation has also been invoked to account for recently uncovered high-resistance or insulating phases of matter. To address this possibility, we have used nanotechnology to create an insulating system that we can probe directly for Cooper pairs. I will present the evidence that Cooper pairs exist and dominate the electrical transport in these insulators and I will discuss how these findings provide new insight into superconductor to insulator quantum phase transitions.

A Review of Irradiation Effects on Organic-Matrix Insulation  

SciTech Connect

This review assesses the data base on epoxy and polyimide matrix insulation to determine whether organic electric insulation systems can be used in the toroidal field (TF) magnets of next generation fusion devices such as ITER* and TPX*. Owing to the difficulties of testing insulation under fusion reactor conditions, there is a considerable mismatch between the ITER requirements and the data that are currently available. For example, nearly all of the high-dose (5 x 10{sup 7} to 10{sup 8} Gy) data obtained on epoxy and polyimide matrix insulation employed gamma irradiation, electron irradiation, or reactor irradiation with a fast neutron fluence far below 10{sup 23}/m{sup 2}, the fluence expected for the insulation at the TF magnets, as set forth in ITER conceptual design documents. Also, the neutron spectrum did not contain a very high energy (E {ge} 5 MeV) component. Such data underestimate the actual damage that would be obtained with the neutron fluence and spectrum expected at a TF magnet. Experiments on a polyimide (Kapton) indicate that gamma or electron doses or mixed gamma and neutron reactor doses would have to be downgraded by a factor of up to ten to simulate fusion neutron doses. Even when neutrons did constitute a significant portion of the total dose, B-containing E-glass reinforcement was often used; therefore, excess damage from the {sup 10}B + n {yields} {sup 7}Li + {alpha} reaction occurred near the glass-epoxy interface. This problem can easily be avoided by substituting B-free glass (R, S, or T types).

Research Needs: Glass Solar Reflectance and Vinyl Siding  

SciTech Connect

The subject of glass solar reflectance and its contribution to permanent vinyl siding distortion has not been extensively studied, and some phenomena are not yet well understood. This white paper presents what is known regarding the issue and identifies where more research is needed. Three primary topics are discussed: environmental factors that control the transfer of heat to and from the siding surface; vinyl siding properties that may affect heat build-up and permanent distortion; and factors that determine the properties of reflected solar radiation from glass surfaces, including insulating window glass. Further research is needed to fully characterize the conditions associated with siding distortion, the scope of the problem, physical properties of vinyl siding, insulating window glass reflection characteristics, and possible mitigation or prevention strategies.

Highly Insulating Windows - Cost  

NLE Websites -- All DOE Office Websites (Extended Search)

Cost Cost The following is an estimate of the cost effective incremental cost of highly-insulating windows (U-factor=0.20 Btu/hr-ft2-F) compared to regular ENERGY STAR windows (U-factor 0.35 Btu/hr-ft2-F). Energy savings from lower U-factors were simulated with RESFEN over an assumed useful window life of 25 years. To determine the maximum incremental cost at which highly-insulating windows would still be cost-effective, we used a formula used by many utility companies to calculate the cost of saved energy from energy efficiency programs, based on the programs' cost and savings. We turned this formula around so that the cost of saved energy equals the present energy prices in the studied locations, whereas the program cost (the incremental cost of the windows) is the dependent variable.

Frames Frames Research performed at the Norwegian University of Science and Technology and LBNL has identified various highly insulating frame solutions. A report was released in 2007 describing some of these frames. This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m2K ), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC.

Smoldering combustion hazards of thermal insulation materials  

SciTech Connect

Work on the smolder ignitability in cellulosic insulation and on thermal analytical characterization of the oxidation of this material is presented. Thermal analysis (TGA and DSC) shows that both retarded and unretarded cellulosic insulation oxidizes in two overall stages, both of which are exothermic. The second stage (oxidation of the char left as a residue of the first stage) is much more energetic on a unit mass basis than the first. However, kinetics and a sufficient exothermicity make the first stage responsible for ignition in most realistic circumstances. Existing smolder retardants such as boric acid have their major effect on the kinetics of the second oxidation stage and thus produce only a rather small (20/sup 0/C) increase in smolder ignition temperature. Several simplified analogs of attic insulations have been tested to determine the variability of minimum smolder ignition temperature. These employed planar or tubular constant temperature heat sources in a thermal environment quite similar to a realistic attic application. Go/no-go tests provided the borderline (minimum) ignition temperature for each configuration. The wide range (150/sup 0/C) of minimum ignition temperatures confirmed the predominant dependence of smolder ignition on heat flow geometry. Other factors (bulk density, retardants) produced much less effect on ignitability.

CRYSTALLIZATION IN MULTICOMPONENT GLASSES  

SciTech Connect

In glass processing situations involving glass crystallization, various crystalline forms nucleate, grow, and dissolve, typically in a nonuniform temperature field of molten glass subjected to convection. Nuclear waste glasses are remarkable examples of multicomponent vitrified mixtures involving partial crystallization. In the glass melter, crystals form and dissolve during batch-to-glass conversion, melter processing, and product cooling. Crystals often agglomerate and sink, and they may settle at the melter bottom. Within the body of cooling glass, multiple phases crystallize in a non-uniform time-dependent temperature field. Self-organizing periodic distribution (the Liesegnang effect) is common. Various crystallization phenomena that occur in glass making are reviewed.

Multiple layer insulation cover  

DOE Patents (OSTI)

A multiple layer insulation cover for preventing heat loss in, for example, a greenhouse, is disclosed. The cover is comprised of spaced layers of thin foil covered fabric separated from each other by air spaces. The spacing is accomplished by the inflation of spaced air bladders which are integrally formed in the cover and to which the layers of the cover are secured. The bladders are inflated after the cover has been deployed in its intended use to separate the layers of the foil material. The sizes of the material layers are selected to compensate for sagging across the width of the cover so that the desired spacing is uniformly maintained when the cover has been deployed. The bladders are deflated as the cover is stored thereby expediting the storage process and reducing the amount of storage space required.

Potential for energy conservation in the glass industry  

SciTech Connect

While the glass industry (flat glass, container glass, pressed and blown glass, and insulation fiber glass) has reduced its specific energy use (Btu/ton) by almost 30% since 1972, significant potential for further reduction still remains. State-of-the-art technologies are available which could lead to incremental improvements in glass industry energy productivity; however, these technologies must compete for capital with projects undertaken for other reasons (e.g., capacity expansion, equipment rebuild, labor cost reduction, product quality improvement, or compliance with environmental, health or safety regulations). Narrowing profit margins in the large tonnage segments of the glass industry in recent years and the fact that energy costs represent less than 25% of the value added in glass manufacture have combined to impede the widespread adoption of many state-of-the-art conservation technologies. Savings in energy costs alone have not provided the incentive to justify the capital expenditures required to realize the energy savings. Beyond implementation of state-of-the-art technologies, significant potential energy savings could accrue from advanced technologies which represent a radical departure from current glass making technology. Long-term research and development (R and D) programs, which address the technical and economic barriers associated with advanced, energy-conserving technologies, offer the opportunity to realize this energy-saving potential.

Bioactive Glass Scaffolds for Bone Regeneration  

NLE Websites -- All DOE Office Websites (Extended Search)

Bioactive Glass Scaffolds for Bioactive Glass Scaffolds for Bone Regeneration Bioactive Glass Scaffolds for Bone Regeneration Print Wednesday, 28 September 2011 00:00 Natural materials are renowned for their unique combination of outstanding mechanical properties and exquisite microstructure. For example, bone, cork, and wood are porous biological materials with high specific stiffness (stiffness per unit weight) and specific strength. The outstanding mechanical properties of these materials are attributed to their anisotropic structures, which have optimized strength-to-density and stiffness-to-density ratios. Working at ALS Beamline 8.3.2, researchers from Berkeley Lab and the Imperial College London have created bioactive glass scaffolds that mirror nature's efficient materials. The three-dimensional glass scaffold is as porous as trabecular bone, has a compressive strength comparable to that of cortical bone, and a strength-to-porosity ratio higher than any previously reported scaffolds.

Compression of felt?type thermal insulation layer for underfloor heating system and floor impact sound  

Science Journals Connector (OSTI)

In Korea almost every house uses underfloor heating which has advantages of thermal comfort and energy efficiency. However when it is constructed for high?rise apartment houses it yields a problem in floor impact sound insulation. It accounts for the fact that a foam?type thermal insulator sandwiched between structural slab and heating floor functions as a spring and easily transmits impacts on the floor to the slab. In that case the system's transmissibility is determined by dynamic stiffness of the thermal insulation layer and the lower the dynamic stiffness is the more the floor impact is isolated. For that reason apartments construction companies are attempting to lower the dynamic stiffness of the thermal insulation layer for impact sound reduction. As part of the attempt felt?type materials with relatively low dynamic stiffness such as glass wool or polyester felt are considered as a substitution for the foam?type thermal insulator. However there is a possibility that compression of the felt?type materials would increase the dynamic stiffness and the impact sound insulation effect at early stage might be weakened in the long term. This paper investigates the correlation between gradual compression of the felt?type thermal insulation layer and the impact sound variation.

Structure of rhenium-containing sodium borosilicate glass  

SciTech Connect

A series of sodium borosilicate glasses were synthesized with increasing fractions of KReO4 or Re2O7, to 10000 ppm (1 mass%) target Re in glass, to assess the effects of large concentrations of rhenium on glass structure and to estimate the solubility of technetium, a radioactive component in typical low active waste nuclear waste glasses. Magic angle spinning nuclear magnetic resonance (MAS-NMR), Fourier transform infrared (FTIR) spectroscopy, and Raman spectroscopy were performed to characterize the glasses as a function of Re source additions. In general, silicon was found coordinated in a mixture of Q2 and Q3 structural units, while Al was 4-coordinated and B was largely 3-coordinate and partially 4-coordinated. The rhenium source did not appear to have significant effects on the glass structure. Thus, at the up to the concentrations that remain in dissolved in glass, ~3000 ppm Re by mass maximum. , the Re appeared to be neither a glass-former nor a strong glass modifier., Rhenium likely exists in isolated ReO4- anions in the interstices of the glass network, as evidenced by the polarized Raman spectrum of the Re glass in the absence of sulfate. Analogous to SO42-¬ in similar glasses, ReO4- is likely a network modifier and forms alkali salt phases on the surface and in the bulk glass above solubility.

The influence of different electricity-to-emissions conversion factors on the choice of insulation materials  

Science Journals Connector (OSTI)

Abstract The current practice of building energy upgrade typically uses thick layers of insulation in order to comply with the energy codes. Similarly, the Norwegian national energy codes for residential buildings are moving towards very low U-values for the building envelope. New and more advanced materials, such as vacuum insulation panels (VIPs) and aerogel, have been presented as alternative solutions to commonly used insulation materials. Both aerogel and \\{VIPs\\} offer very high thermal resistance, which is a favourable characteristic in energy upgrading as the same insulation level can be achieved with thinner insulation layers. This paper presents the results of energy use and lifecycle emissions calculations for three different insulation materials (mineral wool, aerogel, and vacuum insulation panels) used to achieve three different insulation levels (0.18 W/m2 K, 0.15 W/m2 K, and 0.10 W/m2 K) in the energy retrofitting of an apartment building with heat pump in Oslo, Norway. As advanced insulation materials (such as VIP and aerogel) have reported higher embodied emissions per unit of mass than those of mineral wool, a comparison of performances had to be based on equivalent wall U-values rather than same insulation thicknesses. Three different electricity-to-emissions conversion factors (European average value, a model developed at the Research Centre on Zero Emission Buildings – ZEB, and the Norwegian inland production of electricity) are used to evaluate the influence of the lifecycle embodied emissions of each insulation alternative. If the goal is greenhouse gas abatement, the appraisal of buildings based solely on their energy use does not provide a comprehensive picture of the performance of different retrofitting solutions. Results show that the use of the conversion factor for Norwegian inland production of electricity has a strong influence on the choice of which of the three insulation alternatives gives the lowest lifecycle emissions.

Chapter 14 - Glass Recycling  

Science Journals Connector (OSTI)

Abstract Glass has established itself as an essential material in our lives. The composition of glass depends on what it is used for, but the majority of glass in circulation is of the soda-lime–silicate type. It is a material that is eminently recyclable, in the sense that it merely needs to be remelted and reformed to produce another glass article. However, glass must be color-sorted and processed to remove contaminants to ensure it is compatible with the product being manufactured. The key benefit of recycling via remelting is the reduced energy demand. However, because differences in color composition can arise between recovered glass and manufacturing output, alternative outlets are also often necessary. This chapter examines both the recycling of glass back into glass manufacture and these alternatives.

Method for forming silicon on a glass substrate  

DOE Patents (OSTI)

A method by which single-crystal silicon microelectronics may be fabricated on glass substrates at unconventionally low temperatures. This is achieved by fabricating a thin film of silicon on glass and subsequently forming the doped components by a short wavelength (excimer) laser doping procedure and conventional patterning techniques. This method may include introducing a heavily boron doped etch stop layer on a silicon wafer using an excimer laser, which permits good control of the etch stop layer removal process. This method additionally includes dramatically reducing the remaining surface roughness of the silicon thin films after etching in the fabrication of silicon on insulator wafers by scanning an excimer laser across the surface of the silicon thin film causing surface melting, whereby the surface tension of the melt causes smoothing of the surface during recrystallization. Applications for this method include those requiring a transparent or insulating substrate, such as display manufacturing. Other applications include sensors, actuators, optoelectronics, radiation hard and high temperature electronics.

Approximating Metal-Insulator Transitions  

E-Print Network (OSTI)

We consider quantum wave propagation in one-dimensional quasiperiodic lattices. We propose an iterative construction of quasiperiodic potentials from sequences of potentials with increasing spatial period. At each finite iteration step the eigenstates reflect the properties of the limiting quasiperiodic potential properties up to a controlled maximum system size. We then observe approximate metal-insulator transitions (MIT) at the finite iteration steps. We also report evidence on mobility edges which are at variance to the celebrated Aubry-Andre model. The dynamics near the MIT shows a critical slowing down of the ballistic group velocity in the metallic phase similar to the divergence of the localization length in the insulating phase.

Assessment of health implications related to processing and use of natural wool insulation products  

Science Journals Connector (OSTI)

Abstract This paper discusses possible health implications related to dust particles released during the manufacture of sheep's wool-based non-woven insulation material. Such insulation may replace traditional synthetic insulation products used in roofs, wall cavities, etc. A review of the literature concerning organic dusts in general and sheep's wool fiber summarizes dust exposure patterns, toxicological pathways and the hazards imposed by inhalation and explosion risk. This paper highlights a need for more research in order to refrain from overgeneralizing potential pulmonary and carcinogenic risks across the industries. Variables existing between industries such as the use of different wool types, processes, and additives are shown to have varying health effects. Within the final section of the paper, the health issues raised are compared with those that have been extensively documented for the rock and glass wool industries.

The influence of the insulator surface in the plasma focus behavior  

Science Journals Connector (OSTI)

The insulator (Pyrex glass pipe in our system) surface alteration suffered due to successive plasma focus discharges was found to be responsible for the improvement in stabilization in the plasma focus behavior. The development of microscopic conductive sites (?1 ?m in size) observed on the insulator surface due to the accumulation of successive discharges increases the efficiency by a metal?insulator?metal process on current sheath buildup with an increment in current density during the breakdown. The influence of the surface in the early stage of the discharge and its correlation with the intensity of the pinch was studied by analyzing the Si concentration on the surface of the targets of AISI 304 exposed to the plasmas and ion beams generated in the discharge for different experimental situations.

Vacuum-insulated catalytic converter  

DOE Patents (OSTI)

A catalytic converter has an inner canister that contains catalyst-coated substrates and an outer canister that encloses an annular, variable vacuum insulation chamber surrounding the inner canister. An annular tank containing phase-change material for heat storage and release is positioned in the variable vacuum insulation chamber a distance spaced part from the inner canister. A reversible hydrogen getter in the variable vacuum insulation chamber, preferably on a surface of the heat storage tank, releases hydrogen into the variable vacuum insulation chamber to conduct heat when the phase-change material is hot and absorbs the hydrogen to limit heat transfer to radiation when the phase-change material is cool. A porous zeolite trap in the inner canister absorbs and retains hydrocarbons from the exhaust gases when the catalyst-coated substrates and zeolite trap are cold and releases the hydrocarbons for reaction on the catalyst-coated substrate when the zeolite trap and catalyst-coated substrate get hot.

Use of coconut fiber as a low-cost thermal insulator  

SciTech Connect

Cost is one of the major factors to be considered when choosing a thermal insulator. Design engineers continuously strive to provide the best at the lowest possible cost. In the tropics climate conditions are essentially hot and humid and a cause for daily discomfort. To some extent, air-conditioning of buildings has solved this problem. The major deterrent to air-conditioning is the exorbitant cost of imported thermal insulation materials. This has prompted a search for local, low-cost but effective thermal insulation for buildings. Coconut fiber is available at minimal cost from the copra industry in Trinidad, as it is a waste product from the coconut. The viability of using coconut fiber as building thermal insulation was explored by conducting thermal conductivity tests on 200 mm X 400 mm X 60 mm thick slab-like specimens. The test equipment used was a locally designed constant temperature hot box apparatus. This apparatus was designed to test slab-like specimens under steady-state conditions. The reliability if this experimental set up was checked using Gypsum Plaster. The thermal conductivity test results for coconut fiber over the density range 30 kg/m{sup 3} to 115 kg/m{sup 3} showed the characteristic hooked shape graph for fibrous material. For the 60 mm thick specimens at a mean temperature of 39 C, a minimum thermal conductivity of 0.058 W/mK occurred at an optimum density of 85 kg/m{sup 3}. The thermal conductivity of commonly used industrial insulators, namely loose-fill expanded vermiculite, cellular glass and blanket fiber glass, at a mean temperature of 38 C are 0.066 W/mK, 0.061 W/mK and 0.052 W/mK respectively. When compared, these results show that air dried coconut fiber has far reaching potential for use as an effective building thermal insulation.

Benefits Aerogel insulation products displace current insulation materials. The thermal conductivity of aerogel is very low, allowing it to retain insulation properties at a much thinner thickness. Application Aerogel insulation is appropriate for deployment across piping, ducts, and within most building categories. It should be considered in building design, construction, or major renovation. Key Factors for Deployment Aerogel insulations are more expensive than typical insulations. However, they are ideal for special applications, such as translucent wall panels.

Nonequilibrium viscosity of glass  

Science Journals Connector (OSTI)

Since glass is a nonequilibrium material, its properties depend on both composition and thermal history. While most prior studies have focused on equilibrium liquid viscosity, an accurate description of nonequilibrium viscosity is essential for understanding the low temperature dynamics of glass. Departure from equilibrium occurs as a glass-forming system is cooled through the glass transition range. The glass transition involves a continuous breakdown of ergodicity as the system gradually becomes trapped in a subset of the available configurational phase space. At very low temperatures a glass is perfectly nonergodic (or “isostructural”), and the viscosity is described well by an Arrhenius form. However, the behavior of viscosity during the glass transition range itself is not yet understood. In this paper, we address the problem of glass viscosity using the enthalpy landscape model of Mauro and Loucks [Phys. Rev. B 76, 174202 (2007)] for selenium, an elemental glass former. To study a wide range of thermal histories, we compute nonequilibrium viscosity with cooling rates from 10?12 to 1012?K/s. Based on these detailed landscape calculations, we propose a simplified phenomenological model capturing the essential physics of glass viscosity. The phenomenological model incorporates an ergodicity parameter that accounts for the continuous breakdown of ergodicity at the glass transition. We show a direct relationship between the nonequilibrium viscosity parameters and the fragility of the supercooled liquid. The nonequilibrium viscosity model is validated against experimental measurements of Corning EAGLE XG™ glass. The measurements are performed using a specially designed beam-bending apparatus capable of accurate nonequilibrium viscosity measurements up to 1016?Pa?s. Using a common set of parameters, the phenomenological model provides an accurate description of EAGLE XG™ viscosity over the full range of measured temperatures and fictive temperatures.

Noise?insulation requirements for multi?family dwellings  

Science Journals Connector (OSTI)

Noise insulation standards are part of the California Administrative Code (Title 25 Section 1092). These standards apply to all new multi?family dwelling units such as hotels apartments duplexes townhouses and condominium units. Detached single?family dwellings are specifically excluded. The standards establish minimum requirements for the isolation of interior spaces from exterior noise and set minimum ratings for noise insulation of partitions between dwelling units. A community noise equivalent level (CNEL) of 45 dB is set as the maximum for intrusive noise from exterior sources such as rail or road traffic or aircraft operations. American Society for Testing and Materials (ASTM) testing procedures for party wall and floor/ceiling system sound transmission provide the basis for setting minimum acceptable performance for separations between units. As a consultant to builders planners and architects the site planning and design of residential projects have been examined and field evaluations have been performed on completed projects. Building designs and the selection of suitable building elements (wall construction composites window assemblies vent configurations etc.) which assure compliance with the standards have been identified. The paper provides a brief description of the standards their enforcement pitfalls and an assessment of their impact on residential construction in California.

Irradiation Effect on the Interface of the Composites Used as the Insulation Materials in the Nuclear Fusion Reactor  

Science Journals Connector (OSTI)

Abstract In ITER (International Thermonuclear Experimental Reactor), the insulation materials containing polymeric matrix are the most radiation-sensitive among the materials constituting the superconducting magnet in the nuclear fusion reactor. Insulation materials are fabricated by impregnating the polymeric material into the stacks of alternating layers of polyimide films and glass cloth. There are a lot of studies about irradiation property of each constituent material, whereas few studies are reported about the irradiation effect on the resin -glass cloth and the resin –polyimide film boundary. In this study, we focused on the degradation of the resin-glass cloth boundary. The influence of the surface treatment and the weaving density of the glass cloth on the boundary degradation was evaluated by the mechanical properties before and after irradiation. The composite material specimens were prepared using the glass cloth with different surface treatment, and with different weaving density. The inter laminar shear strength (ILSS) test was conducted to examine the influence of the boundary on the radiation effect. In addition, the fracture mechanism were evaluated by optical micro-scope. Based on the results, it was indicated that the weaving density of the glass cloth is small influence on the irradiation effect and the radiation resistance was improved by the surface treatment.

Critical insulation thickness for maximum entropy generation  

Science Journals Connector (OSTI)

Critical insulation thickness is known to refer to the insulation thickness that maximises the rate of heat transfer in cylindrical and spherical systems. The same analogy is extended to the rate of entropy generation in the present study. The possible critical insulation thickness that yields a maximum rate of entropy generation is investigated. Entropy generation is related to heat transfer through and temperature distribution within the insulation material. It is found that there exists a critical insulation thickness for maximising the rate of entropy generation that is a function of the Bi number and the surface to ambient temperature ratio. The solution of such critical thickness is formulated analytically for both cylindrical and spherical geometries. It is also found that the critical insulation thickness for the rate of entropy generation does not coincide with that for the rate of heat transfer.

Topological Insulators in Three Dimensions  

Science Journals Connector (OSTI)

We study three-dimensional generalizations of the quantum spin Hall (QSH) effect. Unlike two dimensions, where a single Z2 topological invariant governs the effect, in three dimensions there are 4 invariants distinguishing 16 phases with two general classes: weak (WTI) and strong (STI) topological insulators. The WTI are like layered 2D QSH states, but are destroyed by disorder. The STI are robust and lead to novel “topological metal” surface states. We introduce a tight binding model which realizes the WTI and STI phases, and we discuss its relevance to real materials, including bismuth.

The present invention is a cable which, although constructed from inexpensive polyolefin tapes and using typical impregnating oils, furnishes high voltage capability up to 765 kV, and has such excellent dielectric characteristics and heat transfer properties that it is capable of operation at capacities equal to or higher than presently available cables at a given voltage. This is accomplished by using polyethylene, polybutene or polypropylene insulating tape which has been specially processed to attain properties which are not generally found in these materials, but are required for their use in impregnated electrical cables. Chief among these properties is compatibility with impregnating oil.

ITER Central Solenoid Coil Insulation Qualification  

SciTech Connect

Design efforts to bring stresses in the turn and layer insulation within allowables failed. It turned out to be impossible to eliminate high local tensile stresses in the winding pack. When high local stresses can not be designed out, the qualification procedure requires verification of the acceptable structural and electrical strength by testing. We built two 4x4 arrays of the conductor jacket with two options of the CS insulation and subjected the arrays to 1.2 million compressive cycles at 60 MPa and at 76 K. Such conditions simulated stresses in the CS insulation. We performed voltage withstand tests and after end of cycling we measured the breakdown voltages between in the arrays. After that we dissectioned the arrays and studied micro cracks in the insulation. We report details of the specimens preparation, test procedures and test results.

Development of polymer concrete for dike insulation at LNG (Liquid Natural Gas) facilities. Final report, August 1983-July 1984  

SciTech Connect

An insulating polymer concrete (IPC) composite has been developed for possible use as a dike insulation material at Liquid Natural Gas (LNG) storage facilities. Using hermetically sealed glass nodules or expanded perlite aggregates and unsaturated polyester resins, a new class of lightweight polymer concretes can be manufactured. Two application procedures have been identified and shown to be feasible in laboratory studies. Precast IPC composite panels 1-in thick can be bonded to concrete substrates using epoxy gel type adhesives or mortars. Cast-in-place IPC to concrete substrates have been shown to have good bonding and insulating characteristics. Modifications of the mix design to improve the workability and sagging of the IPC for installation on vertical or sloped surfaces is necessary.

DWPF GLASS BEADS AND GLASS FRIT TRANSPORT DEMONSTRATION  

SciTech Connect

DWPF is considering replacing irregularly shaped glass frit with spherical glass beads in the Slurry Mix Evaporator (SME) process to decrease the yield stress of the melter feed (a non-Newtonian Bingham Plastic). Pilot-scale testing was conducted on spherical glass beads and glass frit to determine how well the glass beads would transfer when compared to the glass frit. Process Engineering Development designed and constructed the test apparatus to aid in the understanding and impacts that spherical glass beads may have on the existing DWPF Frit Transfer System. Testing was conducted to determine if the lines would plug with the glass beads and the glass frit slurry and what is required to unplug the lines. The flow loop consisted of vertical and horizontal runs of clear PVC piping, similar in geometry to the existing system. Two different batches of glass slurry were tested: a batch of 50 wt% spherical glass beads and a batch of 50 wt% glass frit in process water. No chemicals such as formic acid was used in slurry, only water and glass formers. The glass beads used for this testing were commercially available borosilicate glass of mesh size -100+200. The glass frit was Frit 418 obtained from DWPF and is nominally -45+200 mesh. The spherical glass beads did not have a negative impact on the frit transfer system. The transferring of the spherical glass beads was much easier than the glass frit. It was difficult to create a plug with glass bead slurry in the pilot transfer system. When a small plug occurred from setting overnight with the spherical glass beads, the plug was easy to displace using only the pump. In the case of creating a man made plug in a vertical line, by filling the line with spherical glass beads and allowing the slurry to settle for days, the plug was easy to remove by using flush water. The glass frit proved to be much more difficult to transfer when compared to the spherical glass beads. The glass frit impacted the transfer system to the point that the test apparatus had to be disassembled to dislodge the plugs created in the system.

Excavationless Exterior Foundation Insulation Field Study  

SciTech Connect

Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. However, such an approach can be very costly and disruptive when applied to an existing home, requiring deep excavation around the entire house. The NorthernSTAR Building America Partnership team implemented an innovative, minimally invasive foundation insulation upgrade technique on an existing home. The approach consisted of using hydrovac excavation technology combined with a liquid insulating foam. The team was able to excavate a continuous 4" wide by 4' to 5' deep trench around the entire house, 128 linear feet, except for one small part under the stoop that was obstructed with concrete debris. The combination pressure washer and vacuum extraction technology also enabled the elimination of large trenches and soil stockpiles normally produced by backhoe excavation. The resulting trench was filled with liquid insulating foam, which also served as a water-control layer of the assembly. The insulation was brought above grade using a liquid foam/rigid foam hybrid system and terminated at the top of the rim joist. Cost savings over the traditional excavation process ranged from 23% to 50%. The excavationless process could result in even greater savings since replacement of building structures, exterior features, utility meters, and landscaping would be minimal or non-existent in an excavationless process.

Insulation failure assessment under random energization overvoltages  

SciTech Connect

This paper offers a new simple approach to the evaluation of the risk of failure of external insulation in view of their known probabilistic nature. This is applied to EHV transmission systems subjected to energization overvoltages. The randomness, both in the applied stresses and insulation`s withstand characteristics are numerically simulated and then integrated to assess the risk of failure. Overvoltage control methods are accounted for, such as the use of pre-insertion breaker resistors, series capacitive compensation, and the installation of shunt reactors.

Electrical Strength of Multilayer Vacuum Insulators  

SciTech Connect

The electrical strength of vacuum insulators is a key constraint in the design of particle accelerators and pulsed power systems. Vacuum insulating structures assembled from alternating layers of metal and dielectric can result in improved performance compared to conventional insulators, but previous attempts to optimize their design have yielded seemingly inconsistent results. Here, we present two models for the electrical strength of these structures, one assuming failure by vacuum arcing between adjacent metal layers and the other assuming failure by vacuum surface flashover. These models predict scaling laws which are in agreement with the experimental data currently available.

We find a semimetal-insulator transition at ?gcrit=1.11±0.06, where ?g?2.16 in vacuum, and ?g?0.79 on a SiO2 substrate. Our analysis uses the logarithmic derivative of the order parameter, supplemented by an equation of state. The insulating phase disappears above a critical number of four-component fermion flavors 4

Asymmetric electroresistance of cluster glass state in manganites  

SciTech Connect

We report the electrostatic modulation of transport in strained Pr{sub 0.65}(Ca{sub 0.75}Sr{sub 0.25}){sub 0.35}MnO{sub 3} thin films grown on SrTiO{sub 3} by gating with ionic liquid in electric double layer transistors (EDLT). In such manganite films with strong phase separation, a cluster glass magnetic state emerges at low temperatures with a spin freezing temperature of about 99?K, which is accompanied by the reentrant insulating state with high resistance below 30?K. In the EDLT, we observe bipolar and asymmetric modulation of the channel resistance, as well as an enhanced electroresistance up to 200% at positive gate bias. Our results provide insights on the carrier-density-dependent correlated electron physics of cluster glass systems.

Eco-efficient waste glass recycling: Integrated waste management and green product development through LCA  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer A new eco-efficient recycling route for post-consumer waste glass was implemented. Black-Right-Pointing-Pointer Integrated waste management and industrial production are crucial to green products. Black-Right-Pointing-Pointer Most of the waste glass rejects are sent back to the glass industry. Black-Right-Pointing-Pointer Recovered co-products give more environmental gains than does avoided landfill. Black-Right-Pointing-Pointer Energy intensive recycling must be limited to waste that cannot be closed-loop recycled. - Abstract: As part of the EU Life + NOVEDI project, a new eco-efficient recycling route has been implemented to maximise resources and energy recovery from post-consumer waste glass, through integrated waste management and industrial production. Life cycle assessment (LCA) has been used to identify engineering solutions to sustainability during the development of green building products. The new process and the related LCA are framed within a meaningful case of industrial symbiosis, where multiple waste streams are utilised in a multi-output industrial process. The input is a mix of rejected waste glass from conventional container glass recycling and waste special glass such as monitor glass, bulbs and glass fibres. The green building product is a recycled foam glass (RFG) to be used in high efficiency thermally insulating and lightweight concrete. The environmental gains have been contrasted against induced impacts and improvements have been proposed. Recovered co-products, such as glass fragments/powders, plastics and metals, correspond to environmental gains that are higher than those related to landfill avoidance, whereas the latter is cancelled due to increased transportation distances. In accordance to an eco-efficiency principle, it has been highlighted that recourse to highly energy intensive recycling should be limited to waste that cannot be closed-loop recycled.

Crystalline fragments in glasses  

Science Journals Connector (OSTI)

The nature of tetrahedral molecular fragments is investigated in SiSe2 glasses using the molecular-dynamics method. The glass consists of both edge-sharing (ES) and corner-sharing tetrahedra. The ES tetrahedra are the building blocks of chain-like-molecular fragments. The two-edge-sharing tetrahedra are the nucleus, and corner-sharing configurations provide connecting hinges between fragments. Statistics of rings and fragments reveals that threefold and eightfold rings are most abundant, chainlike fragments that are typically 10–15 Å long occur mostly in eightfold rings, and the longest fragments occur in elevenfold rings.

Method for forming silicon on a glass substrate  

DOE Patents (OSTI)

A method by which single-crystal silicon microelectronics may be fabricated on glass substrates at unconventionally low temperatures. This is achieved by fabricating a thin film of silicon on glass and subsequently forming the doped components by a short wavelength (excimer) laser doping procedure and conventional patterning techniques. This method may include introducing a heavily boron doped etch stop layer on a silicon wafer using an excimer laser, which permits good control of the etch stop layer removal process. This method additionally includes dramatically reducing the remaining surface roughness of the silicon thin films after etching in the fabrication of silicon on insulator wafers by scanning an excimer laser across the surface of the silicon thin film causing surface melting, whereby the surface tension of the melt causes smoothing of the surface during recrystallization. Applications for this method include those requiring a transparent or insulating substrate, such as display manufacturing. Other applications include sensors, actuators, optoelectronics, radiation hard and high temperature electronics. 15 figs.

Foam insulation for a liquid oxygen densifier  

Science Journals Connector (OSTI)

Analyses indicated that it would not be cost effective to vacuum insulate a 7 foot diameter by 30 foot long liquid nitrogen vessel for a launch facility liquid oxygen densifier. Foam insulation appeared to be the logical choice for this infrequently used ground support equipment but the history of foam problems due to cracking, adhesive failure and internal shearing weighed against the use of commercial spray-on material. These problems were solved with a system consisting of alternate sealing and flexible foam layers: (1) an inner membrane sealed to itself but not attached to the cold shell or pipe; (2) a flexible foam insulation layer; (3) a vapor-tight sealing membrane; (4) a second flexible foam insulation layer and (5) an outer aluminized sealing membrane. The second and subsequent layers are sealed to each underlying layer by flexible foam contact adhesive. The inner sealing membrane is particularly vital in that it allows the first foam layer to expand and contract as the tank temperature changes and it also protects the tank from chloride corrosion from the foam. This paper describes preliminary testing to prove out the system and the steps taken to install flexible foam insulation on the oxygen densifier vessel.

Flipping Photoelectron Spins in Topological Insulators  

NLE Websites -- All DOE Office Websites (Extended Search)

Flipping Photoelectron Spins in Topological Insulators Print Flipping Photoelectron Spins in Topological Insulators Print Inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. This new phase of condensed matter is an insulator in the bulk, yet behaves like a metal on its surface, even at room temperature. The electrons that flow swiftly across the surfaces of TIs are "spin polarized", meaning the electron's spin is locked to its momentum, perpendicular to the direction of travel. These electronic states already promise many uses, but ALS researchers working at Beamline 4.0.3 with a team from Berkeley Lab and the University of California, Berkeley have just made an unexpected discovery about TIs that will broaden their possible range of applications: when hit with a photon beam, the spin polarization of the electrons they emit (in a process called photoemission) can be completely controlled in three dimensions, simply by tuning the polarization of the incident light. This strong effect was not what had been assumed about photoemission from topological insulators, or any other material. Controlling the interaction of polarized light and photoelectron spin opens a wide range of possibilities for TIs.

Separation and concentration of water-borne contaminants utilizing insulator-based dielectrophoresis.  

SciTech Connect

This report focuses on and presents the capabilities of insulator-based dielectrophoresis (iDEP) microdevices for the concentration and removal of water-borne bacteria, spores and inert particles. The dielectrophoretic behavior exhibited by the different particles of interest (both biological and inert) in each of these systems was observed to be a function of both the applied electric field and the characteristics of the particle, such as size, shape, and conductivity. The results obtained illustrate the potential of glass and polymer-based iDEP devices to act as a concentrator for a front-end device with significant homeland security and industrial applications for the threat analysis of bacteria, spores, and viruses. We observed that the polymeric devices exhibit the same iDEP behavior and efficacy in the field of use as their glass counterparts, but with the added benefit of being easily mass fabricated and developed in a variety of multi-scale formats that will allow for the realization of a truly high-throughput device. These results also demonstrate that the operating characteristics of the device can be tailored through the device fabrication technique utilized and the magnitude of the electric field gradient created within the insulating structures. We have developed systems capable of handling numerous flow rates and sample volume requirements, and have produced a deployable system suitable for use in any laboratory, industrial, or clinical setting.

Ion implantation effects in insulators and the long-term stability of radioactive waste storage materials  

Science Journals Connector (OSTI)

Most insulator materials so far proposed for storing high-level radioactive wastes, such as glass and and the constituent minerals of ceramics are nuclear track detectors. Lead ion implantation experiments show that such materials should be transformed into “giant” nuclear tracks, when the internal fluence of heavy recoils emitted during the ?-decay of actinide elements stored in them exceeds a critical value, which corresponds to an equivalent storage period of a few thousand years for the wastes expected from a pressurized water reactor. In contrast, actinide bearing minerals are much more stable against ?-recoil damage. As nuclear tracks are extremely chemical reactive, ?-recoil damage is expected to shorten the lifetime of storage materials such as glass and ceramics against dissolution in ground waters. Fortunately new nuclear track concepts are already yielding guidelines for predicting and improving the long-term stability of storage materials. The results of the present studies also bear on the physics of ion implantation phenomena an insulator targets exposed to high fluences of low energy ions.

12 - Life cycle assessment (LCA) of building thermal insulation materials  

Science Journals Connector (OSTI)

Abstract: In this chapter thermal insulation materials and types of plaster and their properties are described. The impact of the selected thermal insulation materials and plaster on the environment is assessed using LCA analysis. A method of assessing the ecological and economic benefits resulting from thermal insulation of the external walls of buildings is proposed. On this basis, ecological and economic payback periods for thermal insulation are defined as well as the ecological efficiency of thermal insulation. The conducted analyses conclude that thermal insulation of the external walls of buildings is environmentally favourable.

Is graphene in vacuum an insulator?  

E-Print Network (OSTI)

We present evidence, from Lattice Monte Carlo simulations of the phase diagram of graphene as a function of the Coulomb coupling between quasiparticles, that graphene in vacuum is likely to be an insulator. We find a semimetal-insulator transition at $\\alpha_g^\\text{crit} = 1.11 \\pm 0.06$, where $\\alpha_g^{} \\simeq 2.16$ in vacuum, and $\\alpha_g^{} \\simeq 0.79$ on a SiO$_2^{}$ substrate. Our analysis uses the logarithmic derivative of the order parameter, supplemented by an equation of state. The insulating phase disappears above a critical number of four-component fermion flavors $4 < N_f^{\\text{crit}} < 6$. Our data are consistent with a second-order transition.

DOE Patents (OSTI)

The reactor vessel of a nuclear reactor installation which is suspended from the cold leg nozzles in a reactor cavity is provided with a lower thermal insulating barrier spaced from the reactor vessel that has a hemispherical lower section that increases in volume from the center line of the reactor to the outer extent of the diameter of the thermal insulating barrier and smoothly transitions up the side walls of the vessel. The space between the thermal insulating harrier and the reactor vessel forms a chamber which can be flooded with cooling water through passive valving to directly cool the reactor vessel in the event of a severe accident. The passive inlet valve for the cooling water includes a buoyant door that is normally maintained sealed under its own weight and floats open when the cavity is Hooded. Passively opening steam vents are also provided.

Thermal radiative properties of phenolic foam insulation  

Science Journals Connector (OSTI)

Thermal insulation has long been an important subject in engineering. Foam insulations have become the most widely used insulations due to their low cost and ease of procesing. In recent years, phenolic foams find increasing applications because of their fire retardation. This paper presents experimental results of thermal radiative properties of phenolic foams, with or without activated carbon. Transmittance spectra were first taken using FTIR for samples of various densities. Extinction coefficient spectra were then obtained by applying Beer's law. Finally, by using the diffusion approximation, the Rosseland mean extinction coefficients and radiative thermal conductivities were obtained for various temperatures. Results show that the extinction coefficient increases with sample density. The addition of activated carbon increases the extinction coefficient slightly.

Massive Dirac surface states in topological insulator/magnetic insulator heterostructures  

Science Journals Connector (OSTI)

Topological insulators are new states of matter with a bulk gap and robust gapless surface states protected by time-reversal symmetry. When time-reversal symmetry is broken, the surface states are gapped, which induces a topological response of the system to electromagnetic field—the topological magnetoelectric effect. In this paper we study the behavior of topological surface states in heterostructures formed by a topological insulator and a magnetic insulator. Several magnetic insulators with compatible magnetic structure and relatively good lattice matching with topological insulators Bi2Se3, Bi2Te3, Sb2Te3 are identified, and the best candidate material is found to be MnSe, an antiferromagnetic insulator. We perform first-principles calculations in Bi2Se3/MnSe superlattices and obtain the surface state band structure. The magnetic exchange coupling with MnSe induces a gap of ?54 meV at the surface states. In addition we tune the distance between Mn ions and the topological insulator surface to study the distance dependence of the exchange coupling.

Test Report: Cost Effective Foundation Insulation  

SciTech Connect

A field experiment was conducted to demonstrate and quantify the thermal effectiveness of rigid insulation board when installed on the exterior of a buried concrete foundation wall. A heated, insulated box was constructed along one wall of an existing, unheated building to simulate the living space of a home. The crawl space beneath the living space was divided into two sections. One featured external foundation insulation, while the other side had none. 36 temperature and heat flux sensors were installed at predetermined locations to measure the temperature profile and heat flow out of the living space. The temperature profile through the foundation was then used to calculate the total heat flow out of the foundation for both cases. This experiment showed that a significant energy savings is available with exterior foundation insulation. Over the course of 3 months, the heat-loss differential between the insulated and non-insulated foundations was 4.95 kilowatt-hours per lineal foot of foundation wall, for a ratio of 3:1. For a 2200 sq. ft home with a foundation perimeter 200 ft. long, this would amount to a savings of 990 kW-hrs in just 3 months, or 330 kW-hrs per month. Extrapolating to an 8-month heating year, we would expect to save over 2640 kW-hrs per year for such a home. The savings for a basement foundation, rather than a crawlspace, would be approach twice that amount, nearing 5280 kW-hr per year. Because these data were not collected during the coldest months of the year, they are conservative, and greater savings may be expected during colder periods.

Development and Testing of Insulated Drill Pipe  

SciTech Connect

This project has comprised design, analysis, laboratory testing, and field testing of insulated drill pipe (IDP). This paper will briefly describe the earlier work, but will focus on results from the recently-completed field test in a geothermal well. Field test results are consistent with earlier analyses and laboratory tests, all of which support the conclusion that insulated drill pipe can have a very significant effect on circulating fluid temperatures. This will enable the use of downhole motors and steering tools in hot wells, and will reduce corrosion, deterioration of drilling fluids, and heat-induced failures in other downhole components.

Analytical Plan for Roman Glasses  

SciTech Connect

Roman glasses that have been in the sea or underground for about 1800 years can serve as the independent “experiment” that is needed for validation of codes and models that are used in performance assessment. Two sets of Roman-era glasses have been obtained for this purpose. One set comes from the sunken vessel the Iulia Felix; the second from recently excavated glasses from a Roman villa in Aquileia, Italy. The specimens contain glass artifacts and attached sediment or soil. In the case of the Iulia Felix glasses quite a lot of analytical work has been completed at the University of Padova, but from an archaeological perspective. The glasses from Aquileia have not been so carefully analyzed, but they are similar to other Roman glasses. Both glass and sediment or soil need to be analyzed and are the subject of this analytical plan. The glasses need to be analyzed with the goal of validating the model used to describe glass dissolution. The sediment and soil need to be analyzed to determine the profile of elements released from the glass. This latter need represents a significant analytical challenge because of the trace quantities that need to be analyzed. Both pieces of information will yield important information useful in the validation of the glass dissolution model and the chemical transport code(s) used to determine the migration of elements once released from the glass. In this plan, we outline the analytical techniques that should be useful in obtaining the needed information and suggest a useful starting point for this analytical effort.

Mixed polyanion glass cathodes: Iron phosphate vanadate glasses  

SciTech Connect

Mixed polyanion (MP) glasses have been investigated for use as cathodes in lithium ion batteries. MP glass cathodes are similar in composition to theoretically promising crystalline polyanionic (CP) cathodes (e.g., lithium cobalt phosphate, lithium manganese silicate), but with proper polyanion substitution, they can be designed to overcome the key shortcomings of CP cathodes, such as poor electrical conductivity and irreversible phase changes. Iron phosphate/vanadate glasses were chosen as a first demonstration of the MP glass concept. Polyanion substitution with vanadate was shown to improve the intercalation capacity of an iron phosphate glass from almost zero to full theoretical capacity. In addition, the MP glass cathodes also exhibited an unexpected second high-capacity electrochemical reaction. X-ray absorption near-edge structure (XANES) and x-ray diffraction (XRD) of cathodes from cells having different states of charge suggested that this second electrochemical reaction is a glass-state conversion reaction. With a first demonstration established, MP glass materials utilizing an intercalation and/or glass-state conversion reaction are promising candidates for future high-energy cathode research.

Compositional threshold for Nuclear Waste Glass Durability  

SciTech Connect

Within the composition space of glasses, a distinct threshold appears to exist that separates "good" glasses, i.e., those which are sufficiently durable, from "bad" glasses of a low durability. The objective of our research is to clarify the origin of this threshold by exploring the relationship between glass composition, glass structure and chemical durability around the threshold region.

Elaboration And Characterization Of Foam Glass Based On Cullet With Addition Of Soluble Silicates  

SciTech Connect

The politics of the energy saving and of the acoustic comfort buildings is at the heart of the research of new compounds permitting to improve the materials performance actually commercialised. With this aim in view, we'll purpose to elaborate a porous material (foam glass) with addition of soluble silicates (up to 40%) of which the principal material is the waste glass in order to recycle it and improving the present laws about the waste products in closed circuit: (Finished products (leftarrow) waste products (leftarrow) finished products). The investigations have shown that grinding waste glass to particle size less than 0.1 mm and adding 1% of Ca CO{sub 3} content provide production of material with the following properties: particle density 0,5 g/cm{sup 3}, strength 17,50 MPa and water adsorption 95%, the temperature for foaming ranges were determined at 850 deg. C. The microstructures are homogenous, with pore sizes up to 2 mm. The addition of soluble silicates (up to 40%) has resulted in the foam glass of very high porosity. The foam glass is counted among the new glass products meeting certain requirements sought comfort in the building industry in particular (thermal and acoustic insulation). The product obtained present of excellent properties thermal ({lambda} = 0,031 W/m deg. C) and acoustic (R = 15 dB).

Refractory Glass Seals for SOFC  

SciTech Connect

One of the critical challenges facing planar solid oxide fuel cell (SOFC) technology is the need for reliable sealing technology. Seals must exhibit long-term stability and mechanical integrity in the high temperature SOFC environment during normal and transient operation. Several different approaches for sealing SOFC stacks are under development, including glass or glass-ceramic seals, metallic brazes, and compressive seals. Among glass seals, rigid glass-ceramics, self-healing glass, and composite glass approaches have been investigated under the SECA Core Technology Program. The U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL) has developed the refractory glass approach in light of the fact that higher sealing temperatures (e.g., 930-1000 degrees C) may enhance the ultimate in-service bulk strength and electrical conductivity of contact materials, as well as the bonding strength between contact materials and adjacent SOFC components, such as interconnect coatings and electrodes. This report summarizes the thermal, chemical, mechanical, and electrical properties of the refractory sealing glass.

Engineering design of the Z magnetically-insulated transmission lines and insulator stack  

SciTech Connect

A 3.3 m diameter cylindrical insulator stack and a set of 3 m diameter conical magnetically insulated transmission lines (MITLs) were built for the Z accelerator. The 1.7 m tall insulator stack operates at {approx}20 MA and 2.5-3.5 MV, and was instrumented with 12 current and 24 voltage monitors. The insulator stack was concentrically and azimuthally aligned within 1.5 mm. The stack, containing 22 crosslinked polystyrene insulators and 18 grading rings, was designed to provide vertical stability for the MITLs and to resist radial buckling. 2-D and 3-D static finite element analyses (FEA) were used in designing the MITLs to limit gravity deflections to less than .25 mm. 2-D FEA dynamic analyses were done to predict motion and to help design features to restrict damage. Each MITL is divided into four concentric zones which fasten together in a way which facilitates fabrication, limits the extent of possible damage and allows for future changes at minimal cost. The tapered MITLs are supported by feedthrough rings in the insulator stack so that the gaps at small radius are adjustable from 0 to 22 mm. The MITL anodes were instrumented with 24 current monitors and have 48 additional diagnostic locations available. The MITLs were fabricated from 304L stainless steel except the outer anode sections, which were made from 6061-T6 aluminum alloy. Procedures were developed for fabrication of the large and small diameter MITL cones, as well as for the feedthrough rings and grading rings of the stack. The power-flow surfaces were successfully machined to within {+-}.25 mm of the specified contours. A large, multi-trolley MITL handling system was designed to allow for removal, cleaning and replacement of the MITLs for each shot, at a shot rate of 1.5 shots/day. Additional equipment allows for cleaning of the insulators.

Glass Ceramic Formulation Data Package  

SciTech Connect

A glass ceramic waste form is being developed for treatment of secondary waste streams generated by aqueous reprocessing of commercial used nuclear fuel (Crum et al. 2012b). The waste stream contains a mixture of transition metals, alkali, alkaline earths, and lanthanides, several of which exceed the solubility limits of a single phase borosilicate glass (Crum et al. 2009; Caurant et al. 2007). A multi-phase glass ceramic waste form allows incorporation of insoluble components of the waste by designed crystallization into durable heat tolerant phases. The glass ceramic formulation and processing targets the formation of the following three stable crystalline phases: (1) powellite (XMoO4) where X can be (Ca, Sr, Ba, and/or Ln), (2) oxyapatite Yx,Z(10-x)Si6O26 where Y is alkaline earth, Z is Ln, and (3) lanthanide borosilicate (Ln5BSi2O13). These three phases incorporate the waste components that are above the solubility limit of a single-phase borosilicate glass. The glass ceramic is designed to be a single phase melt, just like a borosilicate glass, and then crystallize upon slow cooling to form the targeted phases. The slow cooling schedule is based on the centerline cooling profile of a 2 foot diameter canister such as the Hanford High-Level Waste canister. Up to this point, crucible testing has been used for glass ceramic development, with cold crucible induction melter (CCIM) targeted as the ultimate processing technology for the waste form. Idaho National Laboratory (INL) will conduct a scaled CCIM test in FY2012 with a glass ceramic to demonstrate the processing behavior. This Data Package documents the laboratory studies of the glass ceramic composition to support the CCIM test. Pacific Northwest National Laboratory (PNNL) measured melt viscosity, electrical conductivity, and crystallization behavior upon cooling to identify a processing window (temperature range) for melter operation and cooling profiles necessary to crystallize the targeted phases in the waste form.

Topological Response Theory of Doped Topological Insulators  

Science Journals Connector (OSTI)

We generalize the topological response theory of three-dimensional topological insulators (TI) to metallic systems—specifically, doped TI with finite bulk carrier density and a time-reversal symmetry breaking field near the surface. We show that there is an inhomogeneity-induced Berry phase contribution to the surface Hall conductivity that is completely determined by the occupied states and is independent of other details such as band dispersion and impurities. In the limit of zero bulk carrier density, this intrinsic surface Hall conductivity reduces to the half-integer quantized surface Hall conductivity of TI. Based on our theory we predict the behavior of the surface Hall conductivity for a doped topological insulator with a top gate, which can be directly compared with experiments.

Vacuum insulation properties of phenolic foam  

Science Journals Connector (OSTI)

Characteristic properties of phenolic foam as the interstitial material of a vacuum insulation panel are investigated experimentally. For the measurement of effective thermal conductivity, a vacuum guarded hot plate (VGHP) apparatus is used and the conductivity is measured at various vacuum levels. Radiative properties are found using a Fourier transform infrared spectroscopy (FT-IR) device. Solid conductivity is estimated using the porosity of the foam. Effective thermal conductivity at high level of vacuum is measured to be 5 mW/m K which is sum of solid conductivity (2.56 mW/m K) and radiative conductivity (2.44 mW/m K) with 5% of measurement uncertainty. The pore size of the foam is estimated to be 260 ?m using rarefied gas conduction theory. This ensures insulation performance of phenolic foam up to about 10?3 atm. Other practical characteristics of phenolic foam as the VIP core material are also discussed.

Contaminant trap for gas-insulated apparatus  

DOE Patents (OSTI)

A contaminant trap for a gas-insulated electrical conductor is provided. A resinous dielectric body such as Kel-F wax, grease or other sticky polymeric or oligomeric compound is disposed on the inside wall of the outer housing for the conductor. The resinous body is sufficiently sticky at ambient temperatures to immobilize contaminant particles in the insulating gas on the exposed surfaces thereof. An electric resistance heating element is disposed in the resinous body to selectively raise the temperature of the resinous body to a molten state so that the contaminant particles collected on the surface of the body sink into the body so that the surface of the resinous body is renewed to a particle-less condition and, when cooled, returns to a sticky collecting surface.

BOA: Asbestos pipe-insulation removal robot system, Phase 2. Topical report, January--June 1995  

SciTech Connect

This report explored the regulatory impact and cost-benefit of a robotic thermal asbestos pipe-insulation removal system over the current manual abatement work practice. The authors are currently in the second phase of a two-phase program to develop a robotic asbestos abatement system, comprised of a ground-based support system (including vacuum, fluid delivery, computing/electronics/power, and other subsystems) and several on-pipe removal units, each sized to handle pipes within a given diameter range. The intent of this study was to (i) aid in developing design and operational criteria for the overall system to maximize cost-efficiency, and (ii) to determine the commercial potential of a robotic pipe-insulation abatement system.

Superconducting nano-layer coating without insulator  

E-Print Network (OSTI)

The superconducting nano-layer coating without insulator layer is studied. The magnetic-field distribution and the forces acting on a vortex are derived. Using the derived forces, the vortex-penetration field and the lower critical magnetic field can be discussed. The vortex-penetration field is identical with the multilayer coating, but the lower critical magnetic field is not. Forces acting on a vortex from the boundary of two superconductors play an important role in evaluations of the free energy.

A Topological Glass  

E-Print Network (OSTI)

We propose and study a model with glassy behavior. The state space of the model is given by all triangulations of a sphere with $n$ nodes, half of which are red and half are blue. Red nodes want to have 5 neighbors while blue ones want 7. Energies of nodes with different numbers of neighbors are supposed to be positive. The dynamics is that of flipping the diagonal of two adjacent triangles, with a temperature dependent probability. We show that this system has an approach to a steady state which is exponentially slow, and show that the stationary state is unordered. We also study the local energy landscape and show that it has the hierarchical structure known from spin glasses. Finally, we show that the evolution can be described as that of a rarefied gas with spontaneous generation of particles and annihilating collisions.

Topological insulators with arbitrarily tunable entanglement  

E-Print Network (OSTI)

We elucidate how Chern and topological insulators fulfill an area law for the entanglement entropy. By explicit construction of a family of lattice Hamiltonians, we are able to demonstrate that the area law contribution can be tuned to an arbitrarily small value, but is topologically protected from vanishing exactly. We prove this by introducing novel methods to bound entanglement entropies from correlations using perturbation bounds, drawing intuition from ideas of quantum information theory. This rigorous approach is complemented by an intuitive understanding in terms of entanglement edge states. These insights have a number of important consequences: The area law has no universal component, no matter how small, and the entanglement scaling cannot be used as a faithful diagnostic of topological insulators. This holds for all Renyi entropies which uniquely determine the entanglement spectrum which is hence also non-universal. The existence of arbitrarily weakly entangled topological insulators furthermore opens up possibilities of devising correlated topological phases in which the entanglement entropy is small and which are thereby numerically tractable, specifically in tensor network approaches.

Fracture mechanics of cellular glass  

SciTech Connect

Cellular glasses are prime candidate materials for the structural substrate of mirrored glass for solar concentrator reflecting panels. These materials are brittle, however, and susceptible to mechanical failure from slow crack growth caused by a stress corrosion mechanism. The results are detailed of one part of a program established to develop improved cellular glasses and to characterize the behavior of these and commercially available materials. Commercial and developmental cellular glasses were tested and analyzed using standard testing techniques and models developed from linear fracture mechanics. Two models describing the fracture behavior of these materials are developed. Slow crack growth behavior in cellular glass was found to be more complex than that encountered in dense glasses or ceramics. The crack velocity was found to be strongly dependent upon water vapor transport to the tip of the moving crack. The existence of a static fatigue limit was not conclusively established, however, it is speculated that slow crack growth behavior in Region I may be slower, by orders of magnitude, than that found in dense glasses.

Observation of a Macroscopically Observation of a Macroscopically Quantum-Entangled Insulator Observation of a Macroscopically Quantum-Entangled Insulator Print Wednesday, 27 May 2009 00:00 It has recently been proposed that insulators with large band gaps and strong spin-orbit coupling can host a new phase of quantum matter called a topological insulator that is characterized by entangled wavefunctions. The proposal has now been realized by an international collaboration led by researchers from Princeton University who studied the electronic structure of insulating alloys of bismuth and antimony by means of angle-resolved photoemission spectroscopy (ARPES) and spin-resolved ARPES. Their results constitute the first direct experimental evidence of a topological insulator in nature that is fully quantum entangled. In the future, a detailed study of topological order and quantum entanglement using their method can potentially pave the way for fault-tolerant (topological) quantum computing.

Tunable Geometric Fano Resonances in a Metal/Insulator Stack  

E-Print Network (OSTI)

A metal-insulator-metal-insulator stack is shown to have a Fano resonance in the angular domain. The metal/insulator stack consists of two interacting subsystems, a metallic waveguide mode and a surface plasmon mode, coupled by a finite layer metal film. The two modes in close spatial proximity interfere destructively resulting in level repulsion of two metal/insulator stack modes. By adding a coupling prism to momentum match the input EM field, the reflected field exhibits a geometric Fano resonance. Changes to the waveguide insulator permittivity and thickness are shown to tune the geometric Fano resonance. The geometric Fano resonance is also tuned by variations of the exterior insulator permittivity. At a given frequency, the geometric Fano resonance can be tuned to desired lineshape. In addition, this tunability allows for a geometric Fano resonance for any frequency in the visible range.

Production of a High-Level Waste Glass from Hanford Waste Samples  

SciTech Connect

The HLW glass was produced from a HLW sludge slurry (Envelope D Waste), eluate waste streams containing high levels of Cs-137 and Tc-99, solids containing both Sr-90 and transuranics (TRU), and glass-forming chemicals. The eluates and Sr-90/TRU solids were obtained from ion-exchange and precipitation pretreatments, respectively, of other Hanford supernate samples (Envelopes A, B and C Waste). The glass was vitrified by mixing the different waste streams with glass-forming chemicals in platinum/gold crucibles and heating the mixture to 1150 degree C. Resulting glass analyses indicated that the HLW glass waste form composition was close to the target composition. The targeted waste loading of Envelope D sludge solids in the HLW glass was 30.7 wt percent, exclusive of Na and Si oxides. Condensate samples from the off-gas condenser and off-gas dry-ice trap indicated that very little of the radionuclides were volatilized during vitrification. Microstructure analysis of the HLW glass using Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Analysis (EDAX) showed what appeared to be iron spinel in the HLW glass. Further X-Ray Diffraction (XRD) analysis confirmed the presence of nickel spinel trevorite (NiFe2O4). These crystals did not degrade the leaching characteristics of the glass. The HLW glass waste form passed leach tests that included a standard 90 degree C Product Consistency Test (PCT) and a modified version of the United States Environmental Protection Agency Toxicity Characteristic Leaching Procedure (TCLP).

We study the electronic properties of M\\"{o}bius graphene strip with a zigzag edge. We show that such graphene strip behaves as a topological insulator with a gapped bulk and a robust metallic surface, which enjoys some features due to its nontrivial topology of the spatial configuration, such as the existence of edge states and the non-Abelian induced gauge field. We predict that the topological properties of the M\\"{o}bius graphene strip can be experimentally displayed by the destructive interference in the transmission spectrum, and the robustness of edge states under certain perturbations.

Assuming $AdS_{5}$ UV asymptotics, the small frequency/(temperature) dependence of the AC/(DC) electric conductivity along the director of the helix are computed. A large class of insulating and conducting anisotropic phases is found, as well as isotropic, metallic phases.

Novel metals and insulators from holography  

E-Print Network (OSTI)

Using simple holographic models in $D=4$ spacetime dimensions we construct black hole solutions dual to $d=3$ CFTs at finite charge density with a Q-lattice deformation. At zero temperature we find new ground state solutions with broken translation invariance, either in one or both spatial directions, which exhibit insulating or metallic behaviour depending on the parameters of the holographic theory. For low temperatures and small frequencies, the real part of the optical conductivity has a power-law behaviour, with the exponent determined by the ground state. We also obtain an expression for the the DC conductivity at finite temperature in terms of horizon data of the black hole solutions.

We construct continuum models of 3D and 4D topological insulators by coupling spin-1/2 fermions to an SU(2) background gauge field, which is equivalent to a spatially dependent spin-orbit coupling. Higher dimensional generalizations of flat Landau levels are obtained in the Landau-like gauge. The 2D helical Dirac modes with opposite helicities and 3D Weyl modes with opposite chiralities are spatially separated along the third and fourth dimensions, respectively. Stable 2D helical Fermi surfaces and 3D chiral Fermi surfaces appear on open boundaries, respectively. The charge pumping in 4D Landau level systems shows quantized 4D quantum Hall effect.

Natural analogues of nuclear waste glass corrosion.  

SciTech Connect

This report reviews and summarizes studies performed to characterize the products and processes involved in the corrosion of natural glasses. Studies are also reviewed and evaluated on how well the corrosion of natural glasses in natural environments serves as an analogue for the corrosion of high-level radioactive waste glasses in an engineered geologic disposal system. A wide range of natural and experimental corrosion studies has been performed on three major groups of natural glasses: tektite, obsidian, and basalt. Studies of the corrosion of natural glass attempt to characterize both the nature of alteration products and the reaction kinetics. Information available on natural glass was then compared to corresponding information on the corrosion of nuclear waste glasses, specifically to resolve two key questions: (1) whether one or more natural glasses behave similarly to nuclear waste glasses in laboratory tests, and (2) how these similarities can be used to support projections of the long-term corrosion of nuclear waste glasses. The corrosion behavior of basaltic glasses was most similar to that of nuclear waste glasses, but the corrosion of tektite and obsidian glasses involves certain processes that also occur during the corrosion of nuclear waste glasses. The reactions and processes that control basalt glass dissolution are similar to those that are important in nuclear waste glass dissolution. The key reaction of the overall corrosion mechanism is network hydrolysis, which eventually breaks down the glass network structure that remains after the initial ion-exchange and diffusion processes. This review also highlights some unresolved issues related to the application of an analogue approach to predicting long-term behavior of nuclear waste glass corrosion, such as discrepancies between experimental and field-based estimates of kinetic parameters for basaltic glasses.

Sound insulation ratings—the STC revisited  

Science Journals Connector (OSTI)

About twenty years ago building authorities and their acoustical experts were faced with a confusing variety of schemes for rating the sound insulation of walls and floors. There was need for a definitive rating system that would digest the 16 transmission loss values that characterize a partition and produce a single number that would describe its sound insulation performance especially in respect to multi?family dwellings. Two standards committees ISO/TC 43 and ASTM E6 (now E33) began more or less together to develop a new improved rating system to fill this need. The product of these labors was what is known in North America as the ASTM sound transmission class (STC). This rating system was so successful that it was almost universally adopted—even in applications for which it was not intended. Despite the apparent success there is now increasing awareness of imperfections in the system. These are examined in light of accumulated data and experience to see whether the system could or should be improved by certain minor changes.

Multiple reentrant glass transitions in confined hard-sphere glasses  

E-Print Network (OSTI)

Glass forming liquids exhibit a rich phenomenology upon confinement. This is often related to the effects arising from wall-fluid interactions. Here we focus on the interesting limit where the separation of the confining walls becomes of the order of a few particle diameters. For a moderately polydisperse, densely packed hard-sphere fluid confined between two smooth hard walls, we show via event-driven molecular dynamics simulations the emergence of a multiple reentrant glass transition scenario upon a variation of the wall separation. Using thermodynamic relations, this reentrant phenomenon is shown to persist also under constant chemical potential. This allows straightforward experimental investigation and opens the way to a variety of applications in micro- and nanotechnology, where channel dimensions are comparable to the size of the contained particles. The results are in-line with theoretical predictions obtained by a combination of density functional theory and the mode-coupling theory of the glass transition.

Development of Pre?Preg Ceramic Insulation for Superconducting Magnets  

Science Journals Connector (OSTI)

A new pre?impregnated (pre?preg) ceramic?based electrical insulation system capable of surviving high superconductor reaction temperatures has been developed for use in superconducting magnets. The use of Nb 3Sn superconductors holds great promise for increased magnet performance for high energy physics fusion and other applications. A robust cost?effective manufacturing process is critical to the successful implementation of these coils. Due to its embrittlement after the high temperature reaction cycle Nb 3Sn cable is usually insulated and wound into the coil prior to heat treatment. An earlier ceramic?based insulation system applied using wet?winding or vacuum impregnation has been successfully used in the “wind and react” fabrication process. Use of the new pre?preg system will further simplify the manufacturing process while improving control over the insulation properties. Pre?preg insulation offers several advantages including improved dimensional control of the insulation controllable and uniform fiber to matrix ratio and certainty that the insulation does not infiltrate the superconductor. This paper describes the pre?preg development process processing properties as well as insulation performance data at cryogenic temperatures.

In our study, a series of lab-scale crucible tests were performed on designed glasses of different compositions to further investigate and simulate the effect of Cr, Ni, Fe, Al, Li, and RuO2 on the accumulation rate of spinel crystals in the glass discharge riser of the HLW melter. The experimental data were used to expand the compositional region covered by an empirical model developed previously (Matyᚠet al. 2010b), improving its predictive performance. We also investigated the mechanism for agglomeration of particles and impact of agglomerates on accumulation rate. In addition, the TL was measured as a function of temperature and composition.

Crystal structure of Sr-akermanite glass–ceramics  

Science Journals Connector (OSTI)

A glass–ceramic of Sr-akermanite (Sr2MgSi2O7, SG: P 4 ¯ 2 1 m ) was prepared by crystallization of a glass with composition of 2SrOMgO3SiO2. Parameters of the crystal structure were refined by Rietveld method. The analysis of the experimental results showed the following: the unit cell of Sr-akermanite in the glass–ceramic is larger than in single crystal. The thermal expansion coefficients of Sr-akermanite, calculated from the lattice constants obtained from X-ray diffractograms at high temperatures, were ?a = 3.663 × 10?6 K?1 and ?c = 6.666 × 10?6 K?1. It is suggested that the atomic displacements from the atomic coordination in single crystal depend on the stress developed during the crystallization process and the thermal contraction stress developed during cooling. Both types of stresses are related to the presence of residual glass and should be responsible for the expansion of the crystal lattice.

Experiments Provide First Direct Signatures of a Topological Insulator - a  

NLE Websites -- All DOE Office Websites (Extended Search)

Experiments Provide First Direct Experiments Provide First Direct Signatures of a Topological Insulator - a New Phase of Quantum Matter It has recently been proposed that insulators with large band gap and strong spin-orbit coupling can host a new phase of quantum matter called a topological insulator [1,2]. This exotic phase of matter is a subject of intense research because it is predicted to give rise to dissipationless spin currents [3], quantum entanglements and novel macroscopic behavior that obeys axionic electrodynamics rather than Maxwell's equations [4]. Unlike ordinary quantum phases of matter such as superconductors, magnets or superfluids, topological insulators are not described by a local order parameter associated with a spontaneously broken symmetry but rather by a quantum entanglement of its wave function, dubbed topological order. In a topological insulator this quantum entanglement survives over the macroscopic dimensions of the crystal and leads to surface states that have unusual spin textures.

Tuning of the Metal-Insulator Transition via Alkali Adsorption

Tuning of the Metal-Insulator Transition via Alkali Adsorption Print Tuning of the Metal-Insulator Transition via Alkali Adsorption Print Turning a material from an insulator to a metal, or vice versa, by light irradiation, exposure to electric or magnetic fields, or applying small changes in temperature, pressure, or doping-such intriguing control of a material's electronic properties is possible by exploiting strongly interacting or "correlated" electrons. Now a team of researchers from the University of Kiel in Germany and the ALS has found a novel, surprising way to continuously transform a layered metallic transition-metal compound, TaS2, into an insulator. Using angle-resolved photoemission spectroscopy (ARPES), they have demonstrated that adsorption of alkali atoms onto this material's surface gradually makes it more insulating, although in general, alkali adsorption should lead to more metallic behavior, as alkali atoms easily give away their loosely bound outermost electron.

Design of Experiments Results for the Feedthru Insulator  

SciTech Connect

A design of experiments (DoE) was performed at Ceramtec to improve the yield of a cermet part known as the feedthru insulator. The factors chosen to be varied in this DoE were syringe orifice size, fill condition, solvent, and surfactant. These factors were chosen because of their anticipated effect on the cermet slurry and its consequences to the feedthru insulator in succeeding fabrication operations. Response variables to the DoE were chosen to be indirect indicators of production yield for the feedthru insulator. The solvent amount used to mix the cermet slurry had the greatest overall effect on the response variables. Based upon this DoE, there is the potential to improve the yield not only for the feedthru insulator but for other cermet parts as well. This report thoroughly documents the DoE and contains additional information regarding the feedthru insulator.

Chapter Four - Cryogenic Insulation Systems for LNG Industries  

Science Journals Connector (OSTI)

Abstract The market for liquefied natural gas (LNG) is growing faster than any other market for energy resources. Since LNG is normally carried by ship at -163°C, the functional requirements of a ship carrying LNG include cryogenic reliability due to thermal cyclic stresses and high thermal insulation performance for safe and efficient transportation of LNG. In order to guarantee the LNG cold temperature around -160°C, high-quality insulation installation in accordance with strict specifications is essential. Cryogenic insulation restricts the inflow of atmospheric heat into the pipe or process equipment, keeping the liquid cold and allowing it to retain its form. This chapter covers fundamentals for thermal insulation for various thermal insulation materials in LNG industries.

Development of microwave foaming method for phenolic insulation foams  

Science Journals Connector (OSTI)

Many types of foams are used for thermal insulation in building, frozen food industries and LNG containment systems. Low thermal conductivity, low density and low flammability are required for thermal insulation. Among many foams, phenolic foams are preferred for thermal insulation due to its lower flammability and lower gas generation than any other polymer insulation foams. However, it takes long time to manufacture large size phenolic foams and the environmental regulation limits the use of blowing agents. Urethane foams and polystyrene foams are widely used in spite of their high flammability and toxic gas generation because conventional phenolic foams usually have higher thermal conductivity than expected. In this work, a foaming method for the resole-type phenolic foams was developed using microwave and air instead of blowing agents, and its thermal and mechanical properties were measured. From the measured results, it was found that the phenolic foams developed had low thermal conductivity and low density suitable for insulation foams.

Crystallization of niobium germanosilicate glasses  

SciTech Connect

Niobium germanosilicate glasses are potential candidates for the fabrication of transparent glass ceramics with interesting non-linear optical properties. A series of glasses in the (Ge,Si)O{sub 2}-Nb{sub 2}O{sub 5}-K{sub 2}O system were prepared by melting and casting and their characteristic temperatures were determined by differential thermal analysis. Progressive replacement of GeO{sub 2} by SiO{sub 2} improved the thermal stability of the glasses. Depending on the composition and the crystallization heat-treatment, different nanocrystalline phases-KNbSi{sub 2}O{sub 7}, K{sub 3}Nb{sub 3}Si{sub 2}O{sub 13} and K{sub 3.8}Nb{sub 5}Ge{sub 3}O{sub 20.4} could be obtained. The identification and characterization of these phases were performed by X-ray diffraction and Raman spectroscopy. The 40 GeO{sub 2}-10 SiO{sub 2}-25 Nb{sub 2}O{sub 5}-25 K{sub 2}O (mol%) composition presented the higher ability for volume crystallization and its nucleation temperature was determined by the Marotta's method. An activation energy for crystal growth of {approx}529 kJ/mol and a nucleation rate of 9.7x10{sup 18} m{sup -3} s{sup -1} was obtained, for this composition. Transparent glass ceramics with a crystalline volume fraction of {approx}57% were obtained after a 2 h heat-treatment at the nucleation temperature, with crystallite sizes of {approx}20 nm as determined by transmission electron microscopy. - Abstract: TEM image and XRD pattern of the glass ceramic produced (circles indicate nanocrystals).

Glass Transition in Confined Geometry  

E-Print Network (OSTI)

Extending mode-coupling theory, we elaborate a microscopic theory for the glass transition of liquids confined between two parallel flat hard walls. The theory contains the standard MCT equations in bulk and in two dimensions as limiting cases and requires as input solely the equilibrium density profile and the structure factors of the fluid in confinement. We evaluate the phase diagram as a function of the distance of the plates for the case of a hard sphere fluid and obtain an oscillatory behavior of the glass transtion line as a result of the structural changes related to layering.

PROPERTY CHANGES OF CYANATE ESTER/EPOXY INSULATION SYSTEMS CAUSED BY AN ITER-LIKE DOUBLE IMPREGNATION AND BY REACTOR IRRADIATION  

SciTech Connect

Because of the double pancake design of the ITER TF coils the insulation will be applied in several steps. As a consequence, the conductor insulation as well as the pancake insulation will undergo multiple heat cycles in addition to the initial curing cycle. In particular the properties of the organic resin may be influenced, since its heat resistance is limited. Two identical types of sample consisting of wrapped R-glass/Kapton layers and vacuum impregnated with a cyanate ester/epoxy blend were prepared. The build-up of the reinforcement was identical for both insulation systems; however, one system was fabricated in two steps. In the first step only one half of the reinforcing layers was impregnated and cured. Afterwards the remaining layers were wrapped onto the already cured system, before the resulting system was impregnated and cured again. The mechanical properties were characterized prior to and after irradiation to fast neutron fluences of 1 and 2x10{sup 22} m{sup -2}(E>0.1 MeV) in tension and interlaminar shear at 77 K. In order to simulate the pulsed operation of ITER, tension-tension fatigue measurements were performed in the load controlled mode. The results do not show any evidence for reduced mechanical strength caused by the additional heat cycle.

Strong side of weak topological insulators  

Science Journals Connector (OSTI)

Three-dimensional topological insulators are classified into “strong” (STI) and “weak” (WTI) according to the nature of their surface states. While the surface states of the STI are topologically protected from localization, this does not hold for the WTI. In this work, we show that the surface states of the WTI are actually protected from any random perturbation that does not break time-reversal symmetry, and does not close the bulk energy gap. Consequently, the conductivity of metallic surfaces in the clean system remains finite even in the presence of strong disorder of this type. In the weak disorder limit, the surfaces are found to be perfect metals, and strong surface disorder only acts to push the metallic surfaces inwards. We find that the WTI differs from the STI primarily in its anisotropy, and that the anisotropy is not a sign of its weakness but rather of its richness.
