In 2007, the pulsed laser induced damage threshold (LIDT) of anti-reflecting (AR) microstructures built in fused silica and glass was shown to be up to three times greater than the LIDT of single-layer thin-film AR coatings, and at least five times greater than multiple-layer thin-film AR coatings. This result suggest…
The interactive behavior of flavin adenine dinucleotide (FAD) with a bare glassy carbon electrode (GCE) and a Ru-modified GCE was investigated. The reduction of FAD at a GCE/ruthenium-modified GCE surface is a quasi-reversible, surface-controlled process, and our data implied that the attachment of FAD onto the surfac…
The solubilities of bis(benzoxazolyl-2-methyl) sulfide in ethanol, 1-butanol, 2-propanol, chlorobenzene, toluene, o -xylene, and ethanol + water were measured by a synthetic method. The laser monitoring observation technique was used to determine the disappearance of the solid phase in the solid + liquid mixture. All…
Eu‐activated BaAl 2 S 4 (BaAl 2 S 4 :Eu) blue light emission phosphor has attracted considerable attention recently as a prospective material for full color electroluminescent display applications. Although BaAl 2 S 4 :Eu was discovered over 30 years ago, the solid‐state reaction between metal sulfides in sealed quart…
Using the phase-field method, effects of the surface-tension anisotropy on sidebranching are investigated during solutal dendritic growth. The results show that without external perturbations the surface tension anisotropy has decisive effects on sidebranching and the nonmonotonic behavior of the solute profile along…
Monomolecular water in a solid polymer, which has no effective hydrogen bonding sites, was revealed by temperature-variable Fourier transform infrared spectroscopy to be condensable and crystallizable. Ice Ih formed in the polymer matrix was grown by vapor deposition and was reduced by sublimation. Moreover, rapid coo…
A systematic study was undertaken to improve the laser-damage resistance of multilayer high-reflector coatings for use at 351 nm on the OMEGA EP Laser System. A series of hafnium dioxide monolayer films deposited by electron-beam evaporation with varying deposition rates and oxygen backfill pressures were studied usin…
There exist many investigations of ionic transport in a variety of glasses. These studies exhibit strong correlation between ionic conductivity and activation energy: Typically, it is found that higher conductivity is associated with lower activation energies and vice versa. Although there are explanations for this at…
Reaction pathways, solvent effects and reaction parameters have been investigated for the water exchange on Keggin-Al13 in the aqueous solution by performing supermolecule density functional theory calculations. The calculated results suggest a dissociative (D) mechanism for water exchange on Keggin-Al13 in the aqueou…
Ferroelectric PbHPO 4 nanowires have been successfully prepared from a Pb(II)−IP 6 (IP 6, inositol hexakisphosphate acid) complex, a novel single-source precursor, by a hydrothermal method at 180 °C for 24 h. The structure and morphology of the as-prepared PbHPO 4 nanowires and the Pb(II)−IP 6 complex were systematica…
Material synthesis inspired by novel nacre architecture and mechanism is popular and has attracted more and more attention. In this paper, iso-oriented calcite tablets/layers and amino acid layers were formed alternately on calcite wafers. It is interesting that the neonatal calcite tablets/layers have the same crysta…
We demonstrate three-dimensional directed assembly of single-wall carbon nanotubes (SWNT) into porous alumina nanotemplates on silicon substrates by means of electrophoresis and dielectrophoresis at ambient temperatures. Assembled SWNT provided an interconnection between the surface and base of the nanotemplate. I-V m…
In this study effects of the preparation method on the characteristic properties and CO oxidation activities of Ag2O/Co3O4 catalysts were investigated. Catalysts were prepared by two different methods: sol gel and co-precipitation. N2 physisorption measurements, X-ray diffraction, and scanning electron microscopy meas…
Nano‐sized BaTiO 3 powders with narrow size distribution and high tetragonality were attempted to be synthesized by the rotary‐hydrothermal process in a water system as a novel technique, using a mixture of anatase‐type TiO 2 and Ba(OH) 2 as starting material. The rotary‐hydrothermal syntheses were performed under con…
Unexpected three-dimensional distributions of antiferromagnetic 180 degrees domains are observed in LiCoPO4 and LiNiPO4 by optical second harmonic generation. Domains in LiCoPO4 are isotropic in spite of the quasi-two-dimensional magnetic structure whereas domains in LiNiPO4 are distinctly anisotropic, but in contrast…
The importance of flame-retardant and smoke-suppressed poly(vinyl chloride) (PVC) compositions is increasing gradually in the polymer industry since PVC releases smoke and toxic gases (hydrogen chloride, HCl) during heating at temperatures above 140°C with the result of dehydrochlorination reaction. In this study, the…
Analysis of single crystal X-ray diffraction, neutron powder diffraction, electron diffraction and Zn-K-edge EXAFS data show that Ba2ZnO2Ag2Se2 contains unusual isolated [ZnO2]2- moieties resulting from fragmentation of a ZnO2 infinite plane placed under tension.
We extend umbrella sampling with replica exchange steps to calculate free energies that are important in the self-assembly of peptides. This leads to a more than 10-fold speed up over conventional umbrella sampling, thereby providing a practical method to calculate these free-energy differences. This approach can also…
Recent studies have reported that full monolayers of L-α-dilaurylphosphatidylcholine (L-DLPC) and D-α-dipalmitoylphosphatidylcholine (D-DPPC) formed at interfaces between thermotropic liquid crystals (LCs) and aqueous phases lead to homeotropic (perpendicular) orientations of nematic LCs and that specific binding of p…
This paper reports a straightforward approach in generating spheroid-like particles and also the orientational orders observed in the self-assembly of these particles. Nonspherical particles, such as spheroid-like particles, are useful in both fundamental studies and industrial applications due to the geometry impact…
