Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

Advanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.

Finite temperature Casimir pistons for electromagnetic field with mixed boundary conditions and its classical limit

, 2009
In this paper, the finite temperature Casimir force acting on a two-dimensional Casimir piston due to electromagnetic field is computed. It was found that if mixed boundary conditions are assumed on the piston and its opposite wall, then the Casimir ...
