Dynamic Response Analysis of Roadway Surrounding Rock Induced by Dynamic Load under the Action of Hard and Thick Rock Stratum [PDF]
, 2023 In the process of coal seam mining, there are often hard thick key layers in the overlying strata. Due to the high strength and good integrity of the hard thick key layer, after the hard thick key layer is broken, the overlying strata will collapse and ...

Correlated Metal LaNiO3 as a p‐Type Transparent Conductor
Advanced Functional Materials, EarlyView.p‐type transparent conducting oxides are needed to enable superstrate solar cell geometries with n‐type absorbers. The p‐type correlated metal LaNiO3 combines high optical transmission with low electrical resistivity and is compatible with a range of scalable deposition processes.

Microseismic monitoring of the controls on coastal rock cliff erosion [PDF]
, 2012 The aim of this thesis has been to improve understanding of the controls on coastal rock cliff erosion, utilising microseismic ground motion. Coastal cliff erosion has remained poorly understood, in part confounded by the challenges associated with ...

The Major Problems and Countermeasures on the Shield Machine Tunneling in the Hard Rock Stratum [PDF]
, 2011 With the rapid development of urban construction, the shield construction technology has been greatly developed. Shield tunneling method generally adapts to relatively uniform soil, soft rock and sand rock strata, and the shield tunnel construction has ...

Advanced Functional Materials, EarlyView.A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Advanced Functional Materials, EarlyView.A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Electrostatic Superlattices Beyond 1:1 Stoichiometry
Advanced Functional Materials, EarlyView.Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

New Tehniques of Pressure Relief and Permeability Enhancement by Abrasive Jet in Coal Mine Roadways
Shiyou jixie, 2023 Pure water jet penetration in hard coal seams is deficient for low rock-breaking efficiency and complex operation.This paper presents two new techniques of pressure relief and permeability enhancement by deep penetration with abrasive jet and by radial ...
