Advanced Energy Materials, EarlyView.Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Shatter cones in Illinois: Evidence for metoeritic impacts at Glasford and Des Plaines [PDF]
Shatter cone fragments were recovered from rock cores at two previously suspected, but heretofore unverified, impact structures in Illinois. Both sites are buried features known from geophysical surveys and drill holes.

Discovery Prospects for a Supernova Signature of Biogenic Origin
, 2011 Approximately 2.8 Myr before the present our planet was subjected to the debris of a supernova explosion. The terrestrial proxy for this event was the discovery of live atoms of 60Fe in a deep-sea ferromanganese crust.

American Journal of Industrial Medicine, EarlyView.ABSTRACT We evaluated 12 workers with documented exposure to respirable crystalline silica who were referred to a tertiary care center due to clinical suspicion of silicosis, sarcoidosis, or silicosarcoidosis. Although silica exposure is a well‐established risk factor for silicosis and has been associated with autoimmune diseases, mycobacterial ...

Study on the Fragmentation Characteristics and Dust Generation Mechanism of Coal Cutting by Pick
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT During underground excavation, coal dust generation threatens miners' health and damages ecosystems. Its generation is directly influenced by cutting pick performance and inherent coal properties. This study investigates the effects of coal properties and cutting parameters on coal fragmentation characteristics from a mesoscopic perspective ...
