Abstract Linz‐Donawitz (LD) slag, containing 29% calcium (Ca), 21% iron (Fe), and 5% magnesium (Mg), is a by‐product of the iron and steel‐making industry. It is produced in large quantities in Europe and poses a substantial disposal problem. A field trial was conducted to study whether LD slag could be used as a dolo…
Pulsed laser-induced surface damage experiments were made on the cleaved (001) face of (−)2-(α-methylbenzylamino)-5-nitropyridine crystals at a pulse length of 25 ns FWHM. The highest single-pulse damage threshold value was 24.2 J/cm2 at 1064-nm wavelength for light polarized along the crystallographic a axis, whereas…
Summary X‐ray microtomography (XMT) is a non‐destructive technique that allows the internal structure of a material to be imaged by the spatial distribution of its linear X‐ray absorption coefficients. This paper demonstrates the use of XMT to investigate: (1) the distribution of TiB 2 reinforcement in composites form…

Abstract Elastic moduli of the crystalline regions of cellulose triesters in the direction both parallel E l and perpendicular E t to the chain axis are measured by x‐ray diffraction. E l values for cellulose triesters are as follows: cellulose triacetate (CTA), 33.2 GPa; cellulose tripropionate (CTP), 21.6 GPa; cellu…
The effects of additives on the nonenzymatic deamidation of an Asn residue in a peptide and racemization of Asp and/or Asn in lysozyme were investigated at pH 6 and 100 degrees C. These chemical reactions were accelerated by the addition of phosphate ions. Several salts suppressed the deamidation in the presence of ph…
Abstract A series of experiments involving the combustion of inherently fire‐retarded compounds has been performed using the DIN 53 436 furnace. Six chlorinated compounds comprising four pesticides, an organic solvent, and polyvinyl chloride (PVC) have been investigated with the focus on the combustion efficiency expr…
A comparative study of transient photoconductivity and dark conductivity in the discotic liquid crystal hexahexyloxytriphenylene (HAT6) is reported. In both experiments the transport is dispersive, and the carrier mobilities are essentially identical demonstrating that the presence of the counterions in the chemically…
Broadband dielectric spectroscopy has been employed to study the electric charge transport and molecular dynamics in columnar stacks of liquid crystalline phthalocyanine derivatives, materials which are of interest as one‐dimensional semiconductors or as photoconductors. Three relaxation processes and a conductivity c…
Thin-film decoupling capacitors based on ferroelectric lead lanthanum zirconate titanate (PLZT) films are being developed for use in advanced packages, such as multichip modules. These thin-film decoupling capacitors are intended to replace multilayer ceramic capacitors for certain applications, since they can be more…
We have clarified growth conditions and isolation strategies for the nonagglutinating fimbriae from Proteus mirabilis. Nonagglutinating fimbriae were expressed by all P. mirabilis strains we examined, and the major subunit proteins, which ranged from 23 to 29 kDa as determined by sodium dodecyl sulfate-polyacrylamide…
Efforts to improve the blood compatibility of artificial materials have involved coating the surfaces with heparin. However, the anticoagulation activity of heparin is based on its binding to antithrombin, and if the specific structure involved in this interaction is compromised by the coating procedure, then the acti…
Peak positions of silica structural bands, both in infrared absorption and reflection modes, were used earlier to measure the fictive temperature of silica glass. In the present study, the method was applied to determine the fictive temperatures of a soda‐lime silicate glass. For the silicate glass, the IR absorption…
Abstract Fixation of K in vermiculitic soil and the residual benefit from fertilizer‐K addition are influenced by soil moisture. The purpose of this study was to determine K fixation rates under simulated field moisture regimes. Fixation rates were measured during three consecutive wetting‐drying cycles and in long‐te…
This paper is devoted to the calculation of the density expansions (at fixed temperature) of the Maxwell-Boltzmann thermodynamic functions for a quantum plasma. We start from a standard identity that relates the free energy to the particle correlations. These correlations are represented by diagrammatic series, which…
Abstract High-yield synthesis of pure oxo(phthalocyaninato)titanium(IV) was conveniently achieved by heating a mixture of 1,2-dicyanobenzene, titanium(IV) butoxide, urea, and 1-octanol at 150 °C. It is suggested that a key pathway of the efficient condensation reaction is the complex formation of titanium(IV) butoxide…
In-situ photopolymerization of liquid-crystalline networks offers the opportunity to fix the molecular organisation of any LC phase in a thin plastic film. In addition to that, one has access to a number of additional techniques to affect the molecular organisation during or after the polymerization process which make…
