Research on dust control mechanism of coal baffle based on CFD-DPM model
The fully mechanized mining face is among the most critical areas for dust pollution within a mine, in large mining height faces, the elevated coal fall height during the mining process facilitates the dispersion of particulate matter from the coal ...

Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set records direct sampling of total atmospheric deposition from March 2015 to ...

An interstitium‐mimicking membrane combines three‐dimensional alveolar geometry, high pore interconnectivity, and mechanical compliance to overcome transport limitations of conventional lung‐on‐chip barriers. The resulting platform supports physiologic aerosol transport, quantitative analysis of cross‐barrier particle movement, and reveals divergent ...

A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...

Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

ABSTRACT Background Airway allergies affect 20%–30% of the global population, with pollen and fungal spores representing major environmental triggers. Although fungal spores are far more abundant than pollen, their allergenic role—particularly from phytopathogenic rust fungi such as birch rust (BR)—remains poorly understood.

Selective laser sintering enables the fabrication of personalized oral drug delivery systems using biocompatible thermoplastics such as PA12 and polyethylene, offering controlled release and structural precision. However, high‐energy processing introduces safety concerns, including emissions and micro‐ and nanoplastic formation.

Spatial distribution and migration law of respirable dust in fully mechanized mining face
For the problem that the dust sampling method can only measure the dust mass concentration at fixed working locations, and can not systematically reflect the spatial distribution characteristics and migration rules of the dust mass concentration in the ...
