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

Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Multifunctional Organic and Inorganic Composite Coating for Outdoor Droplet Energy Collection and Water Quality Monitoring

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The difluoropyridine‐based benzoxazine (BA‐fa) was synthesized through a Mannich reaction, and a MoO3‐doped PBA‐fa complex layered DEG was fabricated using an ultrasonic spray coating method, which can not only generate electricity in rainy days but also effectively prevent fires on building roofs, self‐cleaning the surface of buildings on rainy days ...

Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.
