The traditional approach to solving this problem has been to attempt better characterization of active sites on known catalysts, and while some significant advances have been made in this direction, the progress in general has been painfully slow. Another approach, and the one which will be ...
As is known, the geometric and electronic properties of Au particles on the oxide support strongly affect the catalytic activity of Au nanocatalyst4,20,21,22,23. Thus, we first performed AIMD simulations for ceria-supported Au20cluster to illustrate how the finite temperature and the nature of ...
The glutaminase enzymes GAC and GLS2 catalyze the hydrolysis of glutamine to glutamate, satisfying the ‘glutamine addiction’ of cancer cells. They are the targets of anti-cancer drugs; however, their mechanisms of activation and catalytic activity have
Binary phase diagrams usually contain an assortment of single-phase materials known as solid solutions and these have already been introduced in Sections 5.1 and 5.4.3. In the substitutional solid solution alloy the involved solute and solvent atoms are randomly mixed on lattice sites. The single-...
The O22- species on the new active sites of the 2%K-2%Ag/MnO2 catalyst can easily desorb; therefore, the hydroxylated active sites can remain stable. These factors are key to the stable ozone decomposition activity of 2%K-2%Ag/MnO2 catalyst in humid gas. This study represents a critical ...
(2) to identify the respective roles of matrix, bedding-plane fractures and other tectonic structures (stratabound joints and faults) on conducting flow at a range of scales (core-plug vs. well-test scale) and depths (up to 1,100 m BGL) under pumped conditions; and (3) to determine ...

Thus, no direct formation of indanol, as precursor of indanone, via metal-oxo derivatives is likely to occur. The ratio hydroperoxide/indanone is highly dependent on the nature of the transition metal in TPIP-derived complexes.关键词: Copper(II Indane Hydroperoxides ...
Definitive experimental proof for catalytic pathways and active sites during the low-temperature water-gas shift reaction remains elusive. Herein, we combine spectroscopic, kinetic and computational analyses to address the decades-long mechanistic contro
