Groundwater seepage can easily cause large deformation and fracture instability of the surrounding rock in deep roadways, coupling support “yield-bolt-grouting” effectively control occurrence such accidents. This paper takes specific engineering geological conditions water-enriched roadway as research background, revealing mechanism yield-bolt-grouting. The mechanical characteristics yielding tube were determined using lab analysis, an investigation was conducted for high-strength bolts....

Abstract The variation in the width of mining face significantly affects stability face, leading to potential roof fracturing and collapse. Additionally, strong pressure can manifest, severely impeding safe production coal mines. This study uses No. 16705 conventional working Jinda Coal Mine as its engineering background investigate characteristics strata movement instability under conditions variable-width shallow-buried thin seams. First, dynamic load is estimated based on key theory....
Electric field control of exchange bias (EB) plays an important role in spintronics due to its attractive merit lower energy consumption. Here, we propose a novel method for electrically tunable EB at room temperature device with the stack Si/SiO2/Ta/Pt/Ag/Mn-doped ZnO (MZO)/Pt/FeMn/Co/ITO by resistive switching (RS) via electrochemical metallization (ECM). The shows enhanced and weakened when set high-resistance state (HRS) low-resistance (LRS), respectively. For LRS, aberration-corrected...
Abstract Pure nickel and four binary Ni–Cr (5, 10, 20 30 wt%) alloys were exposed to Ar–20O 2 , –20H O Ar–20H (vol.%) at 700°C. In dry wet three 10 formed a three-layered structure: an external NiO layer, inner oxide layer of + Cr 3 internal oxidation zone (IOZ) with dispersed. The Ni–30Cr alloy continuous chromia locally outer islands. pure water vapor, all underwent oxidation, metal expulsion formation. Compared the results 650°C, increasing temperature 700°C did not alter morphology...
With the advantages of low cost and high energy density, Co-free Li-rich layered oxides (LROs) are a potential next-generation lithium-ion battery cathode material for vehicles. However, LROs suffer from defects irreversible O-redox conductivity, producing poor cycling stability rate performance initial Coulombic efficiency (ICE). In this work, ammonium niobium oxalate (C4H4NNbO9·nH2O) treatment strategy is proposed to realize oxygen vacancy construction Nb5+ doping on surface LRO material....
In the reuse stage of a gob-side entry retaining, failure structure and stability main roof have significant effect on safety advanced support ventilation space at working face. this study, field investigation, theoretical analysis, industrial experimentation were performed to analyse fracture characteristics formation process retaining during period. A dynamic-equilibrium mechanical model is presented mechanisms different types short cantilever rock beam structures are clarified. The...
Abstract A new cycad, Leptocycas yangcaogouensis sp. nov., was found in sediments from the Late Triassic western Liaoning, China. The pinnately compound leaves (Pseudoctenis type) are screwed a crown on stem top. leaflets linear, with parallel veins and decurrent bases rachis. leaf persistent. cataphylls intermix leaves. female cone is ovoid shape. characteristics of plant more similar to those gracilis, cycad North America, but species differs L. gracilis size its (7–8 vs. 3–5 cm diameter,...
Orthopedic infection is a serious complication in surgeries and remains great challenge clinics. Here, the natural antimicrobial compound vanillic acid-loaded gold nanospheres/mesoporous silica nanoparticles (VA@Au-MSNs) were fabricated for chemo-photothermal synergistic therapy to orthopedic infections. The shape morphology of Au-MSN VA@Au-MSN observed by scanning electron microscopy transmission microscopy. properties or related components characterized dynamic light scattering,...
This study investigates water-sand bursting disasters associated with fractured rock that affect safe mining in the areas of Western China. A broken seepage rheological test device was developed, and tests were conducted on multiple groups samples single-stage axial loading different load levels. When rheology each group stable, mixed fluid injected into at a certain pressure gradient to conduct masses. It found when porosity mass is within range, does not completely pass through some sand...
