Our state-of-the-art atomistic semi-empirical pseudopotential modelling reveals CdTe/CdSe tetrapods as ideal catalysts for CO2 reduction to CH4, exhibiting potential unprecedented selectivity and unparalleled efficiency.

Several cobalt complexes catalyze the evolution of hydrogen from acidic solutions, both homogeneously and at electrodes. The detailed molecular mechanisms of these transformations remain unresolved, largely owing to the fact that key reactive intermediates have eluded detection. One method of stabilizing reactive intermediates involves minimizing the overall reaction free-energy change. Here, w...

In the last two years, the use of simplified models has facilitated major progress in the globular protein folding problem, viz., the prediction of the three-dimensional (3D) structure of a globular protein from its amino acid sequence. A number of groups have addressed the inverse folding problem where one examines the compatibility of a given sequence with a given (and already determined) str...

Inverse modeling of CO2 satellite observations to better quantify carbon surface fluxes requires a chemical transport model (CTM) to relate the fluxes to the observed column concentrations. CTM transport error is a major source of uncertainty. We show that its effect can be reduced by using CO satellite observations as additional constraint in a joint CO2-CO inversion. CO is measured from space...

Protein contacts contain important information for protein structure and functional study, but contact prediction is very challenging especially for protein families without many sequence homologs. Recently evolutionary coupling (EC) analysis, which predicts contacts by analyzing residue co-evolution in a single target family, has made good progress due to better statistical and optimization te...

We report the use of targeted p- and n-type chemical perturbations to manipulate high-T(C) ferromagnetism in Mn(2+):ZnO and Co(2+):ZnO in predictable and reproducible ways. We demonstrate a clear correlation between nitrogen and high-T(C) ferromagnetism for Mn(2+):ZnO and an inverse correlation for Co(2+):ZnO, both as predicted by recent theoretical models. These chemical perturbations reveal r...

In combined photoemission and inverse photoemission spectroscopy studies, we observe changes in the metal phthalocyanine molecular orbital offsets with respect to the conducting gold substrate Fermi level, with the changing d-electron filling of the metal (II) (Co, Ni, Cu) phthalocyanines. The implication is that the interfacial dipole layer depends upon the choice of metal (Co, Ni, Cu) centers...
