GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching
Advanced Functional Materials, EarlyView.The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Numerical modeling of strain transfer from rock mass to a fibre optic sensor installed inside a grouted borehole [PDF]
, 2012 , 2023Strain measurements in underground excavation are usually done locally, with extensometers or similar devices placed within 10-15 meters of adit or stope faces, mainly to gage development of the EDZ (excavation damaged zone) and assess its ...

Effect of layered joints on rockburst in deep tunnels
International Journal of Coal Science & Technology, 2022 The existence of joints in the surrounding rock mass has a considerable effect on tunnel rockbursts. Herein, we studied the effect of layered joints with different inclination angles and spacings on rockburst in deep tunnels and investigated the failure ...

Displacement Analytic Solution of a Deep Elliptical Tunnel in Transversely Isotropic Rock Mass
, 2011 Sedimentary rocks with layered structure account for two third of global land area, and this proportion is 77.3% in China, lots of metamorphic rocks also have significant features of layered structure, so there are a large number of stability problems ...

Tantalum–Palladium Ultrathin Resistance Hydrogen Sensor
Advanced Functional Materials, EarlyView.Nanoconfined Ta‐alloy thin films enable fast, reversible hydrogen sensing by suppressing unwanted phase transitions. A Ta0.88${\rm Ta}_{0.88}$Pd0.12${\rm Pd}_{0.12}$ sensing layer delivers hysteresis‐free detection from ppb to 100% H2${\rm H}_2$ at room temperature.

Failure behaviors of anisotropic shale with a circular cavity subjected to uniaxial compression
Journal of Rock Mechanics and Geotechnical EngineeringLayered rock formations are frequently encountered during the excavation of underground structures. The stability of such structures is influenced not only by the stress concentration caused by the cavities in the strata but also by the anisotropy of the

Earth pressure on a retaining structure in layered and jointed rock masses
KSCE Journal of Civil Engineering, 2017 This work looked into the earth pressure induced on retaining walls in different rock layer formations and joint conditions. Based on the simulation of a large-scale expermental test, extended numerical tests were carried out focusing on the effect of various rock layer formations on earth pressure characteristics.
