This paper is concerned with reaction systems in which fuel production is achieved by illumination of aqueous solutions. Research interest in this field focuses on the photoredox reaction A + D [graphic omitted] A–+ D+ in which A and D are solutes of which ...
Bromide promoted decompn. of tert-Bu bromide in the presence of triphenylphosphine gives, besides isobutene, hydrogen(triphenyl)phosphonium bromide. When heated to approx. 150 DegC in the presence of xylene, the latter salt liberates hydrogen bromide which ...
Ion-bombarded polystyrene with a 0.5-keV Ar+ beam has been investigated by means of photoelectron spectroscopy performed with synchrotron radiation. After a dose of 10(15) ions/cm2 the evolution of the valence band of the bombarded sample towards an amorph ...
A method for the simultaneous production of hydrogen and oxygen from water by the visible light irradiation of a water solution containing photosensitizer, an electron relay and a suitable combination of redox catalysts. ...

The effects of hydrogen diffusion on p-n GaAs junctions have been studied by electron beam induced current (EBIC) and cathodoluminescence (CL) at room temperature. Hydrogen passivates both the acceptors in the p-side of the junction and the donors in the n ...
