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…

The realization of a ceramic protector covering the subregion of a substrate and using chemical vapor deposition techniques needs the temperature field in the deposition zone to be controlled. A feedback control of this temperature is based on the knowledge of the temperature in the considered subregion. The difficult…

The production of radiolytic species in a pressurized water reactor has been calculated for various initial hydrogen and boron concentrations. The concentration of oxidants decreases with increasing hydrogen concentration, but the decrease is <20% when [H2] is increased from 5 to 50 Ncm3/kg (N refers to normal conditi…
Abstract Morimotoite, Ca 3 TiFe 2+ Si 3 O 12 , has been found in contaminated rocks which are considered to be a kind of endoskarn at Fuka, Bitchu-Cho, Okayama Prefecture, Japan. Morimotoite is derived from andradite, , by the substitution Ti + Fe 2+ = 2Fe 3+ . It is associated with calcite, vesuvianite, grossular, wo…

The piezoresistance and other characteristics of boron doped polycrystalline diamond films (PDF's) were determined by analyzing free-standing films that had been formed on silicon. These structures were adhered to a dielectric substrate, and from bending stresses a gauge factor was estimated. Subsequently, a monolithi…

Abstract Rigid, closed‐cell, polyurethane foam consists of interconnected polyurethane plates that form cells. When this foam is compressed, it exhibits an initial elastic regime, which is followed by a plateau regime in which the load required to compress the foam remains nearly constant. In the plateau regime, cell…
