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

open access: yesDeep 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

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

open access: yesDeep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Bioinspired Janus Evaporator for Efficient Desalination of Saline‐Alkali and Seawater Through Photothermal‐Capillary Effects

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work combines textile technology to ingeniously integrate a hydrophobic PP/MXene photothermal sheath with a hydrophilic cotton core into functionalized yarns, successfully developing a Janus core‐sheath evaporator (PM‐CSY‐F). The evaporator demonstrates outstanding evaporation rates and efficient desalination efficiency when applied to treating ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.
