Abstract The thermodynamic parameters for solution of hydrogen at infinite dilution and the (a+B) plateau thermodynamic properties for hydrogen absorption at moderate temperatures for a series of Pd‐based f.c.c binary alloys with relatively low solute metal content have been correlated from the viewpoint of whether th…
Linear, paraelectric (Pb 0.72 La 0.28 )TiO 3 or PLT(28) thin films with a bandgap>3 eV were deposited on Pt/Ti/SiO 2 /Si substrates by the sol-gel technique. Specific top-contact metals from two distinct groups (i.e., non-noble or M T and noble or M N ; the former being oxidizable transition metals) were selected t…

(sup13)C nuclear magnetic resonance spectroscopy and (sup1)H nuclear magnetic resonance spectroscopy were used to identify and quantify the organic solutes of several strains of halophilic or halotolerant thermophilic bacteria. Two strains of Rhodothermus marinus and four strains of "Thermus thermophilus" grown in com…
Abstract The structure and physical properties of optically active, metal‐free 2,3,9,10,16,17,23,24‐octa ( S ‐3,7‐dimethyloctoxy)phthalocyanine (( S )‐Pc(8,2)) are reported and compared with those of the phthalocyanine with ( R , S ) side chains (mixture of 43 stereoisomers). Unlike the latter compound, ( S )‐Pc(8,2)…

A high-luminance green-emitting electroluminescent (EL) device fabricated using a manganese-activated zinc gallate ( ZnGa 2 O 4 :Mn) thin-film phosphor in conjunction with a thick barium titanate ceramic insulator has been demonstrated. The green emission was observed in EL devices fabricated using as-deposited ZnGa 2…
Corrosion reactions spontaneously generate fluctuations of the corrosion potential and corrosion current, known as electrochemical noise. In certain cases good correlation between electrochemical noise and corrosion rates and types can be achieved by means of spectral analysis. However, due to the chaotic nature of co…
Room-temperature (20° C) epitaxy of high-melting point CeO 2 thin films was achieved for the first time on Si(111) substrates. Cross-sectional high-resolution transmission electron microscopy, Rutherford backscattering spectrometry and ion scattering spectroscopy confirmed the formation of a sharp oxide/silicon hetero…
Aliovalent Nb doping (<10 at.%) of sol—gel‐derived lead zirconate titanate (PZT) thin films was investigated with the intention of improving the ferroelectric properties. Nb addition was found to significantly alter the perovskite crystallization by stabilizing the transient pyrochlore phase, resulting in the reten…
We report storage and electrical switching of holographic image data in an economical polymer-dispersed liquidcrystal material. The hologram is recorded in a fast, single-step process and can be reversibly erased and restored repeatedly by the application of fields of approximately 10-15 V/ microm, with a response tim…
The structure of copper films grown on (0001) sapphire by molecular beam epitaxy at 200°C and 600°C was studied by in situ reflection high-energy electron diffraction (RHEED) and transmission electron microscopy (TEM). Both RHEED and TEM confirm that growth is epitaxial at 200°C, but {111}Cu textured at 600°C. However…

Anecdotal reports suggest that soda lime and Baralyme brand absorbent can degrade inhaled anesthetics to carbon monoxide (CO). We examined the factors that govern CO production and found that these include: 1) The anesthetic used: for a given minimum alveolar anesthetic concentration (MAC)-multiple, the magnitude of C…
We describe LINUS, a hierarchic procedure to predict the fold of a protein from its amino acid sequence alone. The algorithm, which has been implemented in a computer program, was applied to large, overlapping fragments from a diverse test set of 7 X-ray-elucidated proteins, with encouraging results. For all proteins…
Abstract Investigation of the effects of an interfacial modifier on the rheological behavior of binary high‐density polyethylene (HDPE) composites showed that the interfacial modifier significantly changed the melt state behavior of HDPE/carbon black (CB) composites. This suggests that the interfacial adhesion between…

Abstract Four biofiber materials were compared against wood flour for their ability to act as reinforcing fillers in melt‐blended composites with polypropylene as the matrix polymer. The four materials were a waste wood composite (mixture of plywood, particleboard, and fiberboard), kenaf core, a waste jute–polyester c…
