Haloalkane dehalogenase catalyzes the hydrolytic cleavage of carbon-halogen bonds in short-chain haloalkanes. Two tryptophan residues of the enzyme (Trp125 and Trp175) form a halide-binding site in the active-site cavity, and were proposed to play a role in catalysis. The function of these residues was studied by repl…

We investigated the correlation between orientational order and microscopic organization of the molecules in smectic A and chiral (racemic) smectic C phases by means of solid-state C-13 NMR, powder X-ray diffraction, and electrooptical measurements. The compounds under investigation are 4-((S)-2-methyloctanoyl)phenyl…
The residual stresses within a deformation band in a ceriastabilized tetragonal zirconia/alumina (Ce‐TZP/Al 2 O 3 ) ceramic composite are measured by piezo‐spectroscopy, in the zirconia phases from their Raman spectra and in the alumina phase from its Cr 3+ fluorescence. The concentrations of monoclinic zirconia acros…

Shape memory alloy (SMA) composites are a class of smart materials in which embedded nitinol wires are used as actuators. Previous research in SMA composites has been limited to wires using one-way shape memory behavior. The objective of this paper is to assess the feasibility of using two-way shape memory (TWSM) trai…
The effect of the method of silanation of zirconia-silica by 3-methacryloxypropyltrimethoxysilane (MAPM) and 3-acryloxypropyltrimethoxysilane (APM) on the diametral tensile and transverse strength of composites made from these silanated fillers and a urethane dimethacrylate was determined after 0-108 h of boiling in w…

The sintering behavior of doped manganite powders was found to be highly dependent on changes in calcination conditions and A/B cation ratio. Coarsening of combustion synthesized powders by calcination allowed for higher green densities in dry‐pressed compacts, which resulted in higher sintered densities for powders c…
Single crystal silicon field emitters have been modified by surface deposition of diamond using bias-enhanced microwave plasma chemical vapor deposition. Polycrystalline diamond with a high nucleation density (1010/cm2) and small grain size (<20 nm) was achieved on silicon field emitters. Field emission from th…
