Recent progress of the exchange bias based on 2D van der Waals ferromagnet

InfoScience, EarlyView.
Ultrathin magnetic materials could help make smaller, energy‐efficient memories, but their magnetic states must remain stable and controllable. This review brings together recent research on exchange bias, a magnetic pinning effect in layered materials, and explains how interfaces and electrical, thermal or mechanical controls can tune it, with optical

Detection of Molecular High Explosives in Post‐detonation Residue: Environmental Persistence of Days to Months

Propellants, Explosives, Pyrotechnics, EarlyView.
Atmospheric flow tubemass spectrometry detects trace RDX residue in soil and dust collected days to months after large explosive detonations. Post‐detonation soil samples contain detectable RDX aligned with prevailing wind direction and generally decreasing over weeks, while dust and soil samples still show picogram‐level RDX months later, providing ...
