Title: Characterization of the structure of low-e substrates and consequences for IR transflection measurements

Abstract

Spectral distortions caused by the electric field standing wave effect were investigated for two commonly used reflective substrates: low-emissivity glass and gold-coated glass. Our analytical calculations showed that spectral distortions may arise for both incoherent and coherent light sources when performing transflectance measurements. We experimentally confirmed our predictions using a commercial mid-infrared quantum cascade laser microscope and an interferometric infrared imaging system.

  • During the hydrogenation of arenes using the cobalt catalyst precursor (eta{sup 3}{minus}C{sub 3}H{sub 5})Co(dippp) (dippp = 1,3-bis(diisopropylphosphino)propane), a catalytically inactive cobalt hydride was formed. The dark blue hydride complex was isolated and characterized. Paramagnetic behavior was noted for the hydride in solution at 20C; but upon cooling to {minus}95C, the {sup 1}H NMR spectra appears to be that of a diamagnetic compound. The magnetic susceptibility was also noted to decrease to a value of 0.7 mu{sub B} at {minus}95C. Some possible explanations of this magnetic behavior are advanced. 25 refs., 2 figs., 4 tabs.
  • Self-assembly of thiol-terminated single-stranded DNA (HS-ssDNA) on gold has served as an important model system for DNA immobilization at surfaces. Here, we report a detailed study of the surface composition and structure of mixed self-assembled DNA monolayers containing a short alkylthiol surface diluent [11-mercapto-1-undecanol (MCU)] on gold supports. These mixed DNA monolayers were studied with X-ray photoelectron spectroscopy (XPS), near-edge X-ray absorption fine structure spectroscopy (NEXAFS), and fluorescence intensity measurements. XPS results on sequentially adsorbed DNA/MCU monolayers on gold indicated that adsorbed MCU molecules first incorporate into the HS-ssDNA monolayer and, upon longer MCU exposures, displace adsorbed HS-ssDNA molecules frommore » the surface. Thus, HS-ssDNA surface coverage steadily decreased with MCU exposure time. Polarization-dependent NEXAFS and fluorescence results both show changes in signals consistent with changes in DNA orientation after only 30 min of MCU exposure. NEXAFS polarization dependence (followed by monitoring the N 1s{yields}{pi}* transition) of the mixed DNA monolayers indicated that the DNA nucleotide base ring structures are oriented more parallel to the gold surface compared to DNA bases in pure HS-ssDNA monolayers. This indicates that HS-ssDNA oligomers reorient toward a more-upright position upon MCU incorporation. Fluorescence intensity results using end-labeled DNA probes on gold show little observable fluorescence on pure HS-ssDNA monolayers, likely due to substrate quenching effects between the fluorophore and the gold. MCU diluent incorporation into HS-ssDNA monolayers initially increases DNA fluorescence signal by densifying the chemisorbed monolayer, prompting an upright orientation of the DNA, and moving the terminal fluorophore away from the substrate. Immobilized DNA probe density and DNA target hybridization in these mixed DNA monolayers, as well as effects of MCU diluent on DNA hybridization in complex milieu (i.e., serum) were characterized by surface plasmon resonance (SPR) and {sup 32}P-radiometric assays and reported in a related study.« less
  • Advanced imaging and characterization methods have permitted the 3-D and phase-specific reconstruction of dense and opaque samples with features that have a length scale on the order of tens of nanometers and comprised of materials with large X-ray mass absorption coefficients. Engineered materials, like those found in solid oxide fuel cell (SOFC) electrodes, use complex materials that have often limited opportunities to perform 3-D characterization and analysis. Still, characterization and analysis methods are needed to better understand these structures and their functional impact. The development, verification, and validation of methods used by the authors for the characterization and analysis ofmore » the heterogeneous SOFC anode are discussed in this work. These methods include the measurement of the volume fractions of the individual phases, contiguity or volumetric connectivity, tortuosity, and interfacial properties. A second and complementary part of this work will examine quantitative methods that provide detailed descriptions of the structure and its relations to the transport processes that it must support. These efforts are intended to describe the formulation of methods developed to provide insight into the SOFC anode nano/microstructure.« less
