Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity

Advanced Science, EarlyView.
In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

The Moscow Mathematical Society and metric geometry: from Peterson to contemporary research

Transactions of the Moscow Mathematical Society, 2016
The paper is devoted to the presentation of researches on geometry in the Moscow Mathematical Society. Geometry is meant here in a broader sense. The material is organized into the following subjects: manifolds with a metric, in particular manifolds with a Riemannian metric or Riemannian spaces, isometric realizations of abstract metrics as metrics of ...

Mathematical Foundations of Radial Coherential Dynamics — Paper I: Coherent Fields, Adjacency Structure, and Pre-Metric Geometry

This work establishes the first mathematical foundations of Radial Coherential Dynamics (RCD) without presupposing spacetime geometry. Version 1.1 introduces the adjacency structure ∼, resolving the dimensional-collapse problem of v1.0 and allowing spatial structure to emerge independently of coherence. Starting from four primitives — a coherence field,
