For lack of alternatives, echelle-grating diffraction behavior has in the past been modeled on scalar theory, despite observations that indicate significant deviations. To resolve this difficulty a detailed experimental, theoretical, and numerical study is performed for several echelles that work at low (18-13), mediu…
Molecular dynamics simulation results are used to demonstrate the existence of a growing length in supercooled, fragile glass-forming liquids. This length is the longest wavelength, propagating shear wave the fluid can support. Explicit results are reported for an equimolar soft-sphere mixture. A possible connection b…
A homologous series of liquid crystalline cis, cis-(3,5-dihydroxycyclohexyl) 3,4-bis(alkoxy)-benzoates ('two chain' diols) is described. The formation of different mesophase structures by these compounds is influenced by the length of the alkoxy side chains; changes from smectic via cubic to hexagonal columnar mesopha…
Abstract Microcellular polycarbonate is a novel cellular material with cells on the order of 10 μm in diameter and a cell density on the order of 10 9 cells per cm 3 . In this study the room temperature creep response of microcellular polycarbonate is experimentally determined and compared with the creep behavior of p…
In the re-investigation by neutron powder diffraction of 3 mol% yttria–tetragonal zirconia polycrystal (Y-TZP), it was realized that the sample, initially taken to be single-phase tetragonal zirconia, was in fact a two-phase mixture of the tetragonal (80%) and cubic (20%) polymorphs. Two-phase refinement gave for the…

Abstract The pyrolytic processes of polycarbosilane (PCS) to silicon carbide and of polycarbosilazane (PCSZ) to silicon carbonitride were studied by gas analysis, electron spin resonance (ESR), and X-ray diffraction. On the progress of conversion from organic polymers to ceramics above 800 K, decomposition gases like…
The dehydration behavior of an analcime formed by ion exchange from leucite (X-type analcime, or secondary analcime) is contrasted with the behavior of an analcime formed by hydrothermal recrystallization from structurally dissimilar materials (hydrothermal analcime, or H-type analcime). The kinetics of dehydration of…

Use of low‐quality fuels in gas turbines can lead to vana‐dium hot corrosion of stabilized‐zirconia turbine blade coatings. The stabilizing oxide reacts with V 2 O 5 in the melt, forming a vanadate, thus removing the stabilizer from the zirconia. To better understand the vanadation reaction of one such oxide, CeO 2 ,…
Abstract The interaction of chlorine with the hydrogenated diamond surface has been investigated by diffuse reflectance Fourier‐transform Infrared (FTIR) spectroscopy, temperature‐programmed desorption (TPD) spectroscopy, and X‐ray photoelectron spectroscopy (XPS). The hydrogenated diamond surface is chlorinated by th…
Homopolymers of β-butyrolactone, L-lactide, δ-valerolactone, and methyl methacrylate, as well as their block copolymers, were prepared with simple initiator systems based on alkali metal alkoxides and alkali metal supramolecular complexes. The goal was to synthesize polymeric materials with potential biodegradability.

Abstract The effect of synthesis conditions on the electrical conductivity and the morphology of a chemically oxidized polypyrrole was investigated. It was found that the electrical conductivity of polypyrrole was strongly dependent on the pyrrole/FeCl 3 ratio, which controls the redox potential of the reaction medium…
The temperature dependence of the deuteron NMR line shape was studied in pentylcyanobiphenyl (5CB) and octylcyanobiphenyl (8CB) liquid crystals confined in porous silica aerogel matrices with two different pore size distributions. The average pore sizes 〈${\mathit{R}}_{\mathit{c}}$〉 of the two aerogel matrices were 0.…
A notation is introduced and used to transform a conventional specification of the non-bonded force and virial algorithm in the case of periodic boundary conditions into an alternative specification. The implementation of the transformed specification is simpler and typically a factor of 1.5 faster than a conventional…
