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…
As a result of the reassessment of the Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory for the kinetics of nucleation and growth transformations, an integral-equation formulation has been developed instead of the well-known and widely used Avrami equation. The presented formulation considers interfacial and diffusional g…
Laboratory exposures of copper have been performed at exposure conditions comparable to those in the UN ECE exposure program with respect to air flow conditions, relative humidity, and concentration of the gaseous pollutants sulfur dioxide and nitrogen dioxide. Extrapolation of the weight increases in the laboratory e…

During the preparation of alumina supported platinum catalysts, the precursor [Pt(NH3)4](OH)2 decomposes\nto a neutral Pt(NH3)zO species during the drying process at 120 'C. Treatment in flowing hydrogen at 180\n'C leads to partial reduction of the platinum ammine complex and formation of platinum metal particles. A\n…
Abstract New oligomers of N ‐vinyl‐2‐pyrrolidone, functionalized at one end with hydroxy functions, were obtained by radical polymerization in the presence of a hydroxylated compound, namely 2‐isopropoxyethanol, acting as chain‐transfer agent. The oligomeric samples obtained were characterized in terms of molecular we…
Summary A new Nicalon SiC‐based fibre, characterized by a low oxygen content (0–5% wt) has been studied. The absence in this fibre of a continuous Si–C–O phase, which characterized the previous NLM 202 series of fibres, induces larger mean sizes for the constituents: the fibre is composed of β‐SiC grains 5–20 run in d…

Adsorption-desorption of plasma protein on various polymer membranes was evaluated by a dynamic contact angle (DCA) measurement using the Wilhelmy plate method. Poly(ethylene terephthalate) (PET) was used as a substrate membrane; we examined this membrane coated with hydrophilic polymers such as poly[2-methacryloyloxe…
