A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Modeling proppant transport and settling in a 3D propagating fracture

Deep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...
