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.

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Synergistic Optical Strategies for Enhanced Perovskite Photocatalytic Activity

EcoEnergy, EarlyView.
This review addresses bottlenecks of halide perovskites' photoactive components from an optics‐driven perspective and organizes recent advances into four interconnected design principles. This review provides practical design principles and outlines key directions toward efficient, selective, and stable perovskite photocatalysis for CO2 reduction ...

Nanostructured Optical Superabsorbers from Carbon Nanotube Forest for Heat Management Using Environmental Blackbody Radiation from the Visible to Mid‐Infrared

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,
