A low pressure reactor (Knudsen cell) coupled to molecular beam modulated mass spectrometry was used to study the heterogeneous kinetics of the following three systems: (1) NO2 on amorphous carbon, (2) H2O vapor on ice and (3) gaseous HCl on ice. The first ...
Platinum silicide films are widely used in silicon devices for ohmic and Schottky contacts. It has been demonstrated in the recent years that Schottky barriers employing ultra-thin platinum silicide films (thickness < 10 nm) are useful for photodetection i ...
Treatment of RO3SC6H4Me-4 with R1MgBr in THF over Li2CuCl4 at -78 Deg with slowly raising the temp. to room temp. gave, in good yields, the derivs. RR1 (R = e.g. Et, Ph, cyclohexyl, or octyl; R1 = Et, CMe3, Ph, cyclohexyl). [on SciFinder (R)] ...
A one-step procedure for the preparation of ion-selective membranes is described. The method employs the thermally induced gel crystallization of ultrahigh molecular weight poly(ethylene) (UHMW-PE) from a dilute xylene solution. After evaporation of the xy ...
For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3 (perovskite) catalyzed bifunctional oxygen electrodes and 3-D zinc electrodes were prepd. and tested in a bipolar zinc/air battery. In addn., a numerical model for the zinc electrode wa ...
Membranes suitable for microfiltration, ultrafiltration, and dialysis consist of polycation-polyanion complexes prepd. by casting an aq. soln. of CM-cellulose (I) and cellulose sulfate (II) into a film and then treating with a cationic polyelectrolyte. Thu ...

Single crystals of layered semiconductors such as WS2 and MoS2 have already proven their efficiency as active elements in photovoltaic cells. Due to their high optical absorption coefficient in the visible range, these materials could be used in the form o ...
Electron Beam Induced Deposition (EBID) allows deposition of three-dimensional micro- and nano-structures of conductive and insulating materials on a wide range of substrates. The process is based on the decomposition of molecules of a pre-selected precurs ...
