In Situ Structural Evolution and Activity Descriptor of Atomically Dispersed Catalysts During Nitrate Electroreduction

Advanced Science, EarlyView.
The in situ evolution of single‐atom catalysts to metallic nanoclusters during nitrate electroreduction is demonstrated. A direct correlation between the OH binding energy on the metallic clusters and ammonia production rate is established as a key activity descriptor, explaining the superior performance of Ni and Co catalysts.

Dirac-Neutrino Magnetic Moment and the Dynamics of a Supernova Explosion

, 2009
The double conversion of the neutrino helicity $\nu_L \to \nu_R \to \nu_L$ has been analyzed for supernova conditions, where the first stage is due to the interaction of the neutrino magnetic moment with plasma electrons and protons in the supernova core,
