Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

Deep Underground Science and Engineering, EarlyView.
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.

High Cooling Rate for LRE123 Stoichiometry Control in Preparation of High‐Tc Bulk Superconductors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review presents the cooling‐rate‐control melt‐growth (CRCMG) method as an effective strategy for regulating LRE123 cation stoichiometry. By accelerating the cooling rate during crystallization, oxygen vacancies are increased in the growing lattice, which suppresses LRE3+/Ba2+ substitution and yields near‐ideal 1:2:3 stoichiometry with enhanced ...
