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.

A Thermally Robust Luminescent Antimony Halide for Real‐Time Detection of Volatile Iodine at Elevated Temperatures

EcoEnergy, EarlyView.
Zero‐dimensional antimony halides drive efficient iodine capture through electron transfer and display rapid fluorescence quenching at 75°C (348 K), establishing the first luminescent sensor for real‐time I2 detection at elevated temperatures. ABSTRACT Real‐time monitoring of volatile molecular iodine (I2), a hazardous radioactive byproduct of nuclear ...

Phosphate and fluoride removal options for Hanford high‐level waste sludge processing

Environmental Progress &Sustainable Energy, EarlyView.
Abstract High‐phosphate and high‐fluoride sludges represent some of the most challenging waste streams within the Hanford High‐Level Waste (HLW) inventory due to solubility constraints, impacts on glass loading, and corrosion risks during vitrification.

o‐Carborane‐based multi‐resonance thermally activated delayed fluorescence emitter exhibits highly efficient and multifunctional electroluminescence

FlexMat, EarlyView.
By strategically incorporating boron/nitrogen multi‐resonance (B/N‐MR) core into the o‐carborane unit, perfect exciton utilization can be achieved as well as exhibiting stimuli‐responsive properties. The resulting DBN‐oCb‐based organic light‐emitting diode (OLED) demonstrated an impressive external quantum efficiency of 22.3%, the highest reported for ...
