A method for manufacturing porous-wall, hollow-glass microspheres (PWHGMs) over an adjustable range of pore sizes promises to substitute the doped-ceramic packing material employed in various processes, by delivering improved kinetics and a denser, more uniform arrangement of active materials. The…
The use of palladium on carbon powder supports (Pd-CP) has traditionally been a commercially viable means of catalyzing deprotection reactions, despite also requiring substantive quantities of precious metal and limiting the selection of solvents due to low hydrogenation activity. However,…
BASF SE (Ludwigshafen, Germany; edlinks.chemengonline.com/7374-542) has developed a new class of enzymes, called enoate reductases, which can be used for the asymmetric synthesis of chiral intermediates, such as esters and aldehydes. The modified biocatalysts, which the company has patented, are…
Chemists at Stanford University (Calif.; edlinks.chemengonline.com/7374-543) have constructed a field-effect transistor (FET) with graphene that can operate at room temperature. Previous graphene FET demonstrations have been performed at liquid helium temperature (4K). The researchers were able to make 10-nm wide…
Researchers at TU Delft (edlinks.chemengonline.com/7374-544) and the FOM Foundation for Fundamental Research on Matter (Utrecht, both Netherlands) have demonstrated the so-called avalanch effect, where a single photon of light can release more than one electron within a semiconductor crystal. The…
