Sentences with phrase «gallium catalyst»

Scientists from Stanford University, SLAC National Accelerator Laboratory and the Technical University of Denmark have identified a new nickel - gallium catalyst that converts hydrogen and carbon dioxide into methanol at ambient pressure and with fewer side - products than the conventional catalyst.

Not exact matches

In this process, the gallium droplets act as catalysts for the longitudinal growth of the wires.

One group at Lund University in Sweden has been able to kick - start the spontaneous growth of «forests» of 1000 - nm - high «nanowire trees», using 50 - nm - wide clusters of gold as a catalyst, and a gallium phosphide substrate.

In the study, the researchers found that the gallium - nitride nanowire growth orientation strongly depended on the relative concentration of nickel and gold within the catalyst.

Nickel - gallium thin films of various stoichiometries were found to reduce CO2 to methane, ethane, and ethylene, at overpotentials lower than the best polycrystalline catalyst, copper.

Our team started with a nickel - gallium intermetallic catalyst known to be active for thermal CO hydrogenation.

This material, a hybrid formed from interfacing the semiconductor gallium phosphide with a molecular hydrogen - producing cobaloxime catalyst, has the potential to address one of the major challenges in the use of artificial photosynthesis to make renewable solar fuels.

The new JCAP photocathode construct consists of the semiconductor gallium phosphide and a molecular cobalt - containing hydrogen production catalyst from the cobaloxime class of compounds.

Moore and his colleagues found that coating the surface of gallium phosphide with a film of the polymer vinylpyridine alleviates the instability problem, and if the vinylpyridine is then chemically treated with the cobaloxime catalyst, hydrogen production is significantly boosted.
