Metamorphism of hydrothermally altered rocks
, 1998 In some metamorphosed volcanic belts, evidence of premetamorphic hydrothermal activity is preserved in the form of distinct metamorphic mineral assemblages. By considering the effect of metamorphism on rocks of various compositions, it is possible to deduce premetamorphic mineral assemblages, some of which could be products of hydrothermal alteration ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

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.
