Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

open access: yesEnergy Science &Engineering, EarlyView.
This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...

Continuous Detonation Combustor Operating on a Methane–Oxygen Mixture: Test Fires, Thrust Performance, and Thermal State

open access: yesAerospace
Test fires of a rotating detonation engine (RDE) annular combustor operating on a methane–oxygen mixture were conducted. Compared to the original RDE combustor previously tested, it was modified in terms of changing the layout of the water cooling system,

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

open access: yesiMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Harnessing cracks in metal films: Design strategies for stretchable conductors

open access: yesInfoMat, EarlyView.
In stretchable electronics, metal film‐based components function either as strain‐insensitive interconnects/electrodes or as strain‐sensitive sensors, both of which are governed by crack‐induced electromechanical responses, yet these two roles have often been discussed separately in previous reviews.
