· Herein we report that in situ formed gold metal nanoparticles are highly active alysts for the cross coupling of allylstannanes and activated alkylbromides to form C −C bonds. Turnover numbers up to 29 000 could be achieved in the presence of active carbon as solid support, which allowed for convenient alyst recovery and reuse. The present study is a rare case where a gold .

· Refractory gold reserves, which require more sophistied treatment methods in order to achieve oxideore recovery rates, correspond to 24 percent of current gold reserves and 22 percent of gold resources worldwide (Exhibit 1). Despite offering a higher grade, these ores can only be processed using specific pretreatment methods such as ultrafine grinding, bio oxidation, .

Present gold extraction suffers from metal loss in the form of gold adsorbed on active carbon particles that are washed out of the extraction process. Here, we investigate the use of magnetic carbon in the form of carboncoated metal nanomagnets for ionic gold recovery. In contrast to acidlabile iron oxide nanoparticles, the carbon/cobalt nanomagnets resisted dissolution in .

Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption. Each particle, or granule, of carbon provides a large surface area, or pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media.

Activated carbonsupported palladium alysts are liable to progressive deactivation even in the absence of any gaseous contaminants during the oxidation of hydrogen under ambient conditions. The high value of palladium coupled with environmental considerations means that new, efficient and cost effective methods for the quantitative recovery of palladium from such materials are .

· Gold Nanoparticles Recycle CO2 Into Useful Forms of Carbon. Gold nanoparticles make better alysts for CO2 recycling than bulk gold metal. Size is crucial though, since edges produce more desired results than corners (red points, above). Nanoparticles of 8 nm appear to have a better edgetocorner ratio than 4 nm, 6 nm, or 10 nm nanoparticles.
