Advanced Science, EarlyView.An electrochemically induced transformation of polar MgO(111) into Mg(OH)2(001) creates a proton‐conductive hydroxide layer during hydrogen evolution. Operando synchrotron XRD and DFT reveal a low‐barrier Grotthuss proton‐hopping mechanism, establishing a feasible strategy for designing oxide‐hydroxide electrocatalysts with enhanced proton transport ...

Advanced Science, EarlyView.Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...

Second law of thermodynamics and the failure of rock materials
, 2001 The relation of nonequilibrium thermodynamics to some failure and fracture theories of rock mechanics is investigated. The basic concepts are given to connect failure to the properties of material equations describing the elastic properties.

Advanced Science, EarlyView.A type of thermoelectric ionogels with convertible n‐p thermopowers are demonstrated with Seebeck coefficients ranging from ‐3.61 to +9.74 mV K−1. Thus, thermoelectric gating organic electrochemical transistor is achieved by employing ionogel as thermoelectric modules and ionic dielectrics simultaneously, paving the road to self‐powered, highly ...

The computer simulation and prediction of rock fall [PDF]
, 2001 This thesis deals with the study of rock falls using a mathematical model, codified for computer use, entitled GeoFall. GeoFall, which was developed by the author, allows predictions to be made of rock fall trajectories, run out distances and kinetic ...

Advanced Science, EarlyView.A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Advanced Science, EarlyView.This work presents a molecular‐level kinetic regulation strategy employing iodoacetic acid (IAA) to simultaneously suppress point defects and solvent inclusion in solution‐grown Cs4PbI6 single crystals. The obtained crystals demonstrate significantly enhanced charge transport properties, enabling X‐ray detectors with high sensitivity, low noise, and ...

Persistence and tensile strength of incipient rock discontinuities
, 2020 Rock discontinuities are fundamentally important to most rock engineering projects but predicting or measuring their properties such as roughness, aperture, shape and extent (persistence) are fraught with difficulty.
