Photocatalytic Oxygen Evolution with Prussian Blue Coated ZnO Origami Core‐Shell Nanostructures

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Prussian Blue and its derivative hold significant potential for photocatalytic oxygen evolution. IN this contribution the photocatalytic oxygen evolution reaction (OER) was characterized using a hybrid catalyst consisting of Prussian Blue coated ZnO nanostructures. The resulting heterojunction, which was characterized both structurally and functionally,

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.
