Title: Detection of vapor nanobubbles by small angle neutron scattering (SANS)

Abstract

Experiments using boiling water on untreated (roughness 100–300 nm) metal surfaces using small-angle neutron scattering (SANS) show the appearance of structures that are 50–70 nm in size when boiling is present. The scattering signal disappears when the boiling ceases, and no change in the signal is detected at any surface temperature condition below saturation. This confirms that the signal is caused by vapor nanobubbles. Two boiling regimes are evaluated herein that differ by the degree of subcooling (3–10 °C). A polydisperse spherical model with a log-normal distribution fits the SANS data well. In conclusion, the size distribution indicates that a large number of nanobubbles exist on the surface during boiling, and some of them grow into large bubbles.

Protein-based nanobubble x-ray imaging method and agent

Patent Rose-Petruck, Christoph ; Douglas, Trevor ; Rand, Danielle ; ...

Systems, compositions, methods and kits employ protein shells, such as ferritin or viral capsid shells, herein called nanobubbles, to enhance X-ray images of cells or body tissue under certain x-ray imaging methods. The nanobubbles have sub-micron size such as about 10 nm, about 40, 60, or 100 nm and may be functionalized for effective delivery to or uptake by a target tissue, in vivo or a cell culture. The nanobubbles are hollow, having a central core which may be empty or contain a fluid, such that the shells effectively form long-lived bubbles in the imaged environment, and are of lowmore »« less

Effects of soil particles and convective transport on dispersion and aggregation of nanoplastics via small-angle neutron scattering (SANS) and ultra SANS (USANS)

Journal Article Astner, Anton F. ; Hayes, Douglas G. ; Pingali, Sai Venkatesh ; ... - PLoS ONE

Terrestrial nanoplastics (NPs) pose a serious threat to agricultural food production systems due to the potential harm of soil-born micro- and macroorganisms that promote soil fertility and ability of NPs to adsorb onto and penetrate into vegetables and other crops. Very little is known about the dispersion, fate and transport of NPs in soils. This is because of the challenges of analyzing terrestrial NPs by conventional microscopic techniques due to the low concentrations of NPs and absence of optical transparency in these systems. Herein, we investigate the potential utility of small-angle neutron scattering (SANS) and Ultra SANS (USANS) to probemore »« less

Small-Angle and Ultrasmall-Angle Neutron Scattering (SANS/USANS) Study of New Albany Shale: A Treatise on Microporosity

Journal Article Bahadur, Jitendra ; Radlinski, Andrzej P. ; Melnichenko, Yuri B. ; ... - Energy and Fuels

We applied small-angle neutron scattering (SANS) and ultrasmall-angle neutron scattering (USANS) techniques in order to study the microstructure of several New Albany shales of different maturity. It has been established that the total porosity decreases with maturity and increases somewhat for post-mature samples. One new method of SANS data analysis was developed, which allows the extraction of information about the size range and number density of micropores from the relatively flat scattering intensity observed in the limit of the large scattering vector Q. Macropores and significant number of mesopores are surface fractals, and their structure can be described in termsmore »« less

Characterization of porosity in sulfide ore minerals: A USANS/SANS study

Journal Article Xia, F. ; Zhao, J. ; Etschmann, B. E. ; ... - American Mineralogist

Porosity plays a key role in the formation and alteration of sulfide ore minerals, yet our knowledge of the nature and formation of the residual pores is very limited. Herein, we report the application of ultra-small-angle neutron scattering and small-angle neutron scattering (USANS/SANS) to assess the porosity in five natural sulfide minerals (violarite, marcasite, pyrite, chalcopyrite, and bornite) possibly formed by hydrothermal mineral replacement reactions and two synthetic sulfide minerals (violarite and marcasite) prepared experimentally by mimicking natural hydrothermal conditions. USANS/SANS data showed very different pore size distributions for these minerals. Natural violarite and marcasite tend to possess less poresmore »« less
