Abstract The propagation rate coefficient K p of the free‐radical bulk polymerization of styrene is determined between 30 and 90°C up to a maximum pressure of 2800 bar. The data from pulsedlaser polymerizations and product analyses by gel‐permeation chromatography (PLP‐GPC) are adequately represented by the expression…

The collisional deactivation of highly vibrationally excited NO2 and CS2 by a variety of buffer gases has been examined by time-resolved Fourier transform IR emission spectroscopy. The results show that there is a dramatic increase in the average energy removed per collision for NO2 excited above ∼10 000 cm−1 and for…

The symmetry lowering observed when passing from bulk samples to nearly two-dimensional thin magnetic films requires new expressions of the free energy to be derived. A larger number of coefficients must be included to describe the magnetocrystalline anisotropy and magnetoelastic coupling energies, depending on the sy…
Abstract Poly‐3‐hydroxyalkanoates (PHAs) containing repeating units with terminal alkene substituents at the 3‐position were produced by Pseudomonas oleovorans grown with either 7‐octeneoic acid [OA()] alone, or 10‐undeceneoic acid [UND()] alone, or mixtures of UND() and either nonanoic acid (NA) or octanoic acid (…
Abstract The three-dimensional crystal structure of rotationally disordered illite/smectite (I/S) in K-bentonite samples from the Appalachian basin and neighboring areas is described using the parameters of 1) P 0 , the proportion of zero-degree layer stacking rotations, such as in the polytype series 1Md-1M ; 2) P cv…

Abstract In order to realize a higher valency ion conduction in solids, the Sc2(WO4)3 material which possesses a larger tunnel size for ion migration was selected to reduce the electrostatic interaction and the single crystals of Sc2(WO4)3 were grown to eliminate grain boundary effects found in polycrystalline state.…
Measurements of the enthalpy relaxations in liquid orthoterphenyl in the supercooled state have been carried out using specific-heat spectroscopy over the frequency range from 2 Hz to 6.3 kHz, as a function of temperature and as a function of pressure. The observed \ensuremath{\alpha}-relaxation peaks in the phase of…
A comparative study of cyclic fatigue damage from Hertzian contacts in silicon carbide ceramics with homogeneous microstructure (fine, equiaxed grains, strong grain boundaries) and heterogeneous microstructure (coarse, contiguous elongate grains, weak interphase boundaries) is presented. Observations of the surface an…
The solution structure of the isolated fragments 1-20 (beta-hairpin), 21-40 (alpha-helix) and 41-56 (beta-hairpin), corresponding to all the secondary structure elements of the protein G B1 domain, have been studied by circular dichroism and nuclear magnetic resonance techniques. In the protein G B1-(1-20) fragment tu…
Two complexes of gallium with 3-hydroxy-4-pyrones were synthesized as potential pharmaceutical compounds for oral administration. These compounds were analyzed by powder X-ray diffraction followed by computer indexing of the data. The first compound, tris(3-hydroxy-2-methyl-4-pyronato)gallium [Ga(C 6 H 5 O 3 ) 3 ], wa…
