The findings of Liu and Gabbaï also have important ramifications for the field of frustrated Lewis pair (FLP) chemistry. Such systems feature Lewis acids and bases that are sterically precluded from forming adducts, and this enables the activation of small molecules such as dihydrogen (H 2) ().For discrete FLP systems, the reaction of the acid, base, and …

α-Al 2 O 3 or corundum, is one of the hardest known materials on Earth, second only to diamond. Although pure Al2O3 is colorless, trace impurities turn it into a range of colored gemstones such as ruby and sapphire. The α-Al 2 O 3 (0001) crystal surface is commonly used as a substrate for growing thin films in microelectronics, for …
