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.

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Thermoresponsive Gel Polymer Electrolytes Enabled by Retained Double Bonds for Thermal Shutdown in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A smart gel electrolyte with thermal shutdown capability has been proposed enabled by a two‐step cross‐linking strategy, which preserves a high density of unreacted double bonds at room temperature. This strategy brings negligible degradation to room temperature electrochemical performance, while under thermal abuse conditions above 115 °C, the gel ...

Anion‐Synergistic Regulation of Solvation‐Layer Chemistry in Nonflammable Electrolytes Enables Highly Safe and Durable Sodium Metal Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study establishes a new anion‐synergistic solvation chemistry framework for directing interfacial reactions and stabilizing sodium metal anodes. Uncontrolled dendrite growth, accompanied by thermal runaway in sodium metal, remains a critical bottleneck for practical applications of sodium metal batteries (SMBs).

Structure‐Driven Thermal Insulation Through Single‐ and Double‐Shell Hollow Silica Nanospheres Via a Single‐Step Sacrificial‐Interlayer Strategy

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A single‐step sacrificial‐interlayer strategy enables precise modulation of inter‐shell spacing in hollow silica nanospheres, allowing direct comparison of thermal insulation characteristics between single‐ and double‐shell architectures. The hierarchical design amplifies phonon scattering and disrupts solid heat pathways, achieving an ultralow thermal
