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…

Abstract Seven samples from a chronosequence of soils developed in historically created polders on the Atlantic coast (Marais Poitevin, Vendée, France) were investigated in order to illustrate the rate of mineralogical change in a clay-dominated system. The oldest polder was constructed in 1665, the last one in 1912;…

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…

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…
