Nanoarchitectonics of Layered Metal Chalcogenides-Based Ternary Electrocatalyst for Water Splitting
Energies, 2023 The research on renewable energy is actively looking into electrocatalysts based on transition metal chalcogenides because nanostructured electrocatalysts support the higher intrinsic activity for both the hydrogen evolution reaction (HER) and oxygen ...

Metal-non-metal transition in silver chalcogenides
Philosophical Magazine, 1976 Ag2S and Ag2Se undergo polymorphic, first-order transitions at about 133°C and 179°C respectively. Above the transition temperatures both compounds are cubic body centred and characterized by a strongly disturbed sublattice of Ag+ ions in a quasi molten state. This disorder is of course associated with a relatively large ionic conductivity.

Understanding and Designing Phase Change Materials: Insights From Atom Probe Tomography. [PDF]
Adv Sci (Weinh)Atom probe tomography can distinguish metallic, covalent, and metavalent bonds based upon their bond rupture; in particular, the probability to form more than one ion (PME) in laser‐assisted field evaporation. These findings open new avenues in understanding and designing phase change materials (PCMs) since they allow quantification of bonds in solids ...
