The phosphorylation and oxidation state of cofilin1 determines not only its binding capacity to F-actin [34,35,36], it is also essential for translocation to mitochondria [26]. In particular, dephosphorylated cofilin1 attains activity for translocation from the cytosol to mitochondria [37]. In ...
This value is significantly lower than the one (~ 3.64) expected on the basis of the value determined for the Na to Co stoichiometry ratio, x. The "lower-than-expected" value for the Co oxidation state may be alternatively explained by presence of oxygen vacancies or excess protons. More...
Using X-ray absorption spectroscopy (XAS) at the Cu L(2,3) and Co L(2,3) edges, we demonstrate that the valence state of copper in the thiospinel carrollite (CuCo(2)S(4)) is Cu(+) with a d count of Cu d(9.8). The Co has a d count of d(6.4), so that the highly cova...
Variations in the oxidation state of copper during CO catalytic oxidation over powdered CuO and Cu 2 O in a gas mixture of 5% CO/He and air (O 2 ) were investigated by means of an appropriate combination of evolved gas analysis, thermogravimetry, XRD, and FT-IR in the temperature range ...
The objective of this work was to validate experimentally some CO oxidation reaction mechanisms currently used in modelling platinum diesel oxidation catalysts. Many steady-state and transient measurements of catalytic activity involving CO ramps, step-functions and light-offs were made over the typical ...
Steady-state multiplicity was observed in the catalytic oxidation of mixtures of H2 and CO over a cordierite monolith wash-coated with Pt/Al2O3. Increasing the CO concentration or decreasing the H2 concentration across the hysteresis limit results in extinction, whereas decreasing the CO concentration...
The robust topological surface state(s) (TSS) on the three-dimensional topological insulators provide a perfect platform for exploiting surface states in less stringent environments. Employing first-principles density functional theory calculations, we demonstrate that the TSS can play a vital role in ...

Ag decorated topological surface state protected hierarchical Bi2Se3 nanoflakes for enhanced field emission properties The enhanced FE properties of the Ag attached Bi2Se3heterostructure is attributed to the electron injection from Ag nanoparticles to Bi2Se3and also to the formation of extra emitting sit...
An in-depth understanding of the oxidation state of Pt on such oxides and its relationship to the CO oxidation activity is needed. Infrared reflection absorption spectroscopy (IRAS) is often used as a tool for identifying the chemical states of Pt nanoclusters16,17,18,19. If oxidized Pt ...
