Silicon hydrides and nickel complexes : II. Mechanism of the hydrosilylation catalyzed by nickel-phosphine complexes The interchange of hydrogen and chlorine on silicon accompanying the hydrosilylation is related to a high electron density at the nickel atom bearing the phosphine, olefin, and silicon hy...

However, 99.95% pure material, even at concn down to 1% in hydrogen and/or nitrogen, ignites in contact with air unless emerging at very high gas velocity, when mixtures with up to 10% silane content may not ignite. Silane from a cylinder at 24 bar contained inside a ventilated cabinet ...
For silicon and germanium donors, the factors inside the bracket are renormalized, and of particular importance here Ia is ten orders of magnitude smaller for silicon than it is for hydrogen. This is apparent from the formulae of the Hartree energy and Bohr radius for donors in these ...
