Pannierps around 300 and 400°C for W.O. and one distinct step around 300°C for MoO. leaving dimeric W.O. intermediate phase, monomeric WO. and MoO. final phase products, which can be reversibly oxidized in O. at 300°C back to starting metal(VI) oxides. Dimethylmetal precursors are anchored to the BrØnsted

M. E. Safar,J. L. Cuche,B. M. PannierThis polymer may be pyrolysed to give a silicon carbonitride product with an electronic conductivity in the same range as glassy carbon (10. -10. (Ω.cm).. Both FTIR and NMR spectrocopies have been used to determine the structure of the polymer and of the series of intermediate materials that are pro

Endorphins in Mental Health Researchd hydridopolycarbosilane (HPCS) derived from Grignard coupling of Cl.SiCH.Cl followed by LiAlH. reduction. This polymer thermosets on heating at 200–400 °C (or at 100 °C with a catalyst) and gives near stoichiometric SiC in ca. 80% yield on pyrolysis to 1000 °C. Unlike PSE which is difficult to prep

Endoscopic Anatomy of the Paranasal Sinusestiple additions occur, it is difficult to control the level (or stoichiometry) of addition and the regiochemistry of the addition. Separation of pure derivatives of the fullerenes frequently requires extensive chromatography. Crystallization of the fullerenes and their simple derivatives produces so
