Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

Deep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

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.

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors

EcoEnergy, EarlyView.
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.
