Ultrafast Transitions in X‐Ray Irradiated Solids
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Nanolignin Functional Separators for Flexible Lithium–Sulfur Batteries With Enhanced Performance
Nanolignin‐functionalized separators, incorporating lignin nanoparticles into a crosslinked PEGDA coating applied on commercial separators, reduce polysulfide shuttling, thereby enhancing cycling performance in flexible lithium–sulfur pouch cells, while also improving thermo‐oxidative stability and flame retardancy.
