Specialty gases used in PV manufacture are silane (SiH4), ammonia (NH3), nitrous oxide (N2O), carbon dioxide (CO2), methane (CH4), hydrogen fluoride (HF), phosphine (PH3) and diborane
Voltaix Inc, a company involved in the manufacture of a number of electronics products, including germane, diborane
, trisilane, and trimethylboron, has chosen Matthew D Stephens as its executive vice president, sales & marketing.
y]) and/or the formation of diborane
during the hydrogenation and dehydrogenation cycles.
In order to develop selective hosts for anions, we have synthesized a new macrocycle L, from the reaction of isophthalaldehyde and N'-methyl-2, 2'-diaminodiethylamine under high dilution conditions in methanol, followed by diborane
The heats of reaction of diborane
with the methylamines, and of tetramethyldiborane with trimethylamine; the dissociation energy of diborane
Applying the same idea to nanotechnology, Hutchison came up with a process that eliminates diborane
gas and benzene from the production of gold nanoparticles.

G Yes No 0.
The hydride canister treats such gases as arsine, phosphine, diborane
, silane, and organometallics, while the etch-gas canister treats boron trichloride, hydrogen chloride, hydrogen fluoride, dichlorosilane, tetrachlorosilane, and tungsten hexafluoride.
To serve its different customers Novasep Synthesis has developed know-how and innovative technologies using: Hazardous Chemistry: Azide, Diborane
, Diazomethane, Ozonolysis, Carbonylation, Asymmetric technologies: Asymmetric Chemistry, Preparative Chromatography, Synthesis and Purification of Highly Potent Molecules and multi-step, multi-ton synthesis.
The Apex system provides control of germane and diborane
flux for doped silicon germanium films.
A mild reduction of 3 with diborane
 resulted in amine 6 in high yield (Table 1, No.
