| Metallic alloy is tough and ductile at cryogenic temperatures Posted: 04 Sep 2014 11:46 AM PDT A multi-element high-entropy alloy not only tests out as one of the toughest materials on record, but, unlike most materials, the toughness as well as the strength and ductility of this alloy actually improves at cryogenic temperatures. |
| Posted: 04 Sep 2014 11:19 AM PDT Researchers have, for the first time, provided direct evidence of a water-mediated reaction mechanism for the catalytic oxidation of carbon monoxide. The work used gold nanoparticles and titanium dioxide as a catalyst to speed the process and determined that water serves as a co-catalyst for the reaction that transforms carbon monoxide into carbon dioxide. |
