A phase transition at ca 228K in cadmium trithiophosphate, CdPS 3 , has been characterized by means of single-crystal X-ray diffraction. The low-temperature phase crystallizes in trigonal symmetry [a = 6.224(3), c = 19.49 (1) A, V = 654(1) A 3 and Z = 6]. The structure determination was conducted from 679 reflections…
Strong-segregation theory (SST)l models microphase-separated block copolymer melts in terms of polymeric brushes. This approach has provided intuitive and well-accepted explanations for phase behavior far below the order-disorder transition. According to the model, AB diblock copolymers self-assemble with their juncti…

An air‐metal hydride battery (32 Ah) using a noble metal‐free air electrode (300 cm 2 ) was constructed and tested. The battery was charged with a third nickel mesh electrode and discharged using oxygen, with discharge voltages of 0.87 V at 3 A and 0.58 V at 30 A. The peak power was 25 W (83 mW/cm 2 ) with oxygen and…
This is a study of visual contrast sensitivity in a series of subjects with previously diagnosed occupational organic-solvent-induced chronic toxic encephalopathy. Contrast sensitivity was measured for 16 subjects using the Vistech VCTS 6500 chart. The results were compared with age-stratified normal data. Six of the…

A mathematical model for the discharge of a metal‐hydride electrode was developed. The model was used to study the effect of various parameters on predicted discharge curves. The simulations obtained using the model show the expected decrease of charge utilization as the rate of discharge is increased. Increasing the…
The influence of zirconium and hafnium additions in substitution to titanium, is investigated on TiNi shape memory alloy. Microstructural and thermomechanical studies are conducted on an arc-melted Ti38Ni50Hf12 alloy. Results are compared with those of an equiatomic TiNi.
The isocitrate dehydrogenases from the extremely halophilic Archaeon, Haloferax volcanii, and from the hyperthermophilic Archaeon, Sulfolobus solfataricus, have been purified to electrophoretic homogeneity. The purified enzymes have been characterised with respect to their cofactor specificities, subunit compositions…
Tryptophan synthase, an alpha 2 beta 2 tetrameric complex, is a classic example of an enzyme that is thought to "channel" a metabolic intermediate (indole) from the active site of the alpha subunit to the active site of the beta subunit. The solution of the three-dimensional structure of the enzyme from Salmonella typ…

Abstract Scandium(III) trifluoromethanesulfonate was found to be an efficient catalyst as a Lewis acid for the condensation reaction of trimethylhydroquinone with isophytol to afford α-tocopherol. The condensation reaction proceeded smoothly using only a 0.001 molar amount of the catalyst. The catalyst was easily reco…
To incorporate kenaf fibers into textiles, it is important to establish uniformity of fibers extracted from the base to the tip of the plant. Bast fiber quality depends on both physical (crystallinity, crystallite size, and orientation) and chemical (lignin, gum, and hemicellulose) properties. Therefore, the first obj…
We have investigated the local structure about the Cu, Ba, and Hg atoms in ${\mathrm{HgBa}}_{2}$${\mathrm{CuO}}_{4+\mathrm{\ensuremath{\delta}}}$ using the x-ray absorption fine structure (XAFS) technique. We find that most of the local structure results are consistent with the diffraction measurements except for two…
Abstract The addition of NO (0 to 400ppm) to mixtures of H 2 (ca. 1%) and O 2 (0.7 to 22%) has been studied over the temperature range 700 to 825 K, in a flow reactor at atmospheric pressure. The overall effect of NO is to promote the oxidation of H 2 but high concentrations of O 2 actually inhibit the NO‐promoted oxi…
Calponin from chicken gizzard induced polymerization of actin in the presence of 10 mM KCl. Only 2 min after the addition of KCl in the presence of a 0.0625-0.25:1 molar ratio of calponin to actin, a Poisson-type length distribution (with an average length of approx. 0.7 micron) was observed with formed actin filament…
