Indeed, if not chlorinated ( or insufficiently chlorinated ) the platinum and rhenium in the catalyst would be reduced almost immediately to metallic state by the hydrogen in the vapour phase.

The company is the largest independent outsource producer of epiwafers manufactured by metalorganic vapour phase epitaxy ( MOCVD ), molecular beam epitaxy ( MBE ) and chemical vapor deposition ( CVD ).
23.
Below this temperature, the water produced will react with the sodium, above this point, any water formed will be driven off in the vapour phase, creating an essentially anhydrous reaction.
24.
Thin films can be produced by chemical vapor deposition, metalorganic vapour phase epitaxy, electrodeposition, pulsed laser deposition, sputtering, sol-gel synthesis, atomic layer deposition, spray pyrolysis, etc.
25.
As of 2014 multi-junction cells were expensive to produce, using techniques similar to semiconductor device fabrication, usually metalorganic vapour phase epitaxy but on " chip " sizes on the order of centimeters.
26.
One, a standard univerity text, says " sublimation in the process by which a solid passes from solid phase to vapour phase without going through a liquid phase, and occurs at low pressures.
27.
Further interest in artificial snowflake genesis continued in 1979 with Toshio Kurod and Rolf Lacmann, of the Braunschweig University of Technology, publishing " Growth Mechanism of Ice from Vapour Phase and its Growth Forms ".
28.
An enlarged synchrotron X-ray transmission section topograph on the right shows a diffraction image of the section of a sample having a gallium nitride ( GaN ) layer grown by metal-organic vapour phase epitaxy on sapphire wafer.
29.
Probably the most similar main group species is Re 2 O 7 is not molecular but consists of crosslinked Re centers with both tetrahedral and octahedral sites; in the vapour phase it is molecular with a similar structure to Tc 2 O 7.
30.
If the Tolman length is known to be positive ( with k > 0 ) the interface tends to curve towards the liquid phase, whereas a negative Tolman length implies a negative R _ { 0 } and a preferred curvature towards the vapour phase.
