The capacity, power and actions of these actors – and their interactions – offer a "site" for understanding the evolution and regulation of work globally [ 1].
The sites for evolution markers were mapped onto available influenza A virus protein structures, retrieved from the Protein Data Bank (PDB; supplementary table S1).
We determined the active site for hydrogen evolution, a reaction catalyzed by precious metals, on nanoparticulate molybdenum disulfide (MoS2) by atomically resolving the surface of this catalyst before measuring electrochemical activity in solution.
In this case, the base metal behaves as the active site for hydrogen evolution, and hence the hydrogen overpotential of the alloy is close to that of the base metal and less dependent on the alloying element.
After loading Pt cocatalyst as the active site for H2 evolution reaction, the rGO/g-C3N4 composite photocatalysts exhibited an obviously improved performance (ca. 23.7%) by the addition of a small amount of rGO (0.08%), compared with the pure g-C3N4.
We hypothesize that Cd ions form the active site for CO evolution.
By the kinetic considerations, it was clarified that noble metal sites dispersed on the oxide surface serve effectively as an active site for the chlorine evolution reaction.
To illustrate this, I simulated the evolution of a binding site for Bcd (a developmental transcription factor in Drosophila whose specificity is well-characterized) under an HKY model (dotted trace in Figure 1a).
In such a case the alloying element provides preferable sites for hydrogen evolution reactions, since the excess electrons promote proton discharge.
A large amount of nanometric "steps," served as the active sites for hydrogen evolution reaction, were observed.
Among the five samples, the CoO x -loaded SrW(O,N 3 exhibited higher photostability and photocatalytic O2 evolution rate of 3.3 μmol h−1 due to the presence of active sites for O2 evolution on the surfaces and absence of the intrinsic defects related to the partly filled 4f orbitals.
