Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Mongolia at 800: The State and Nation Since Chinggis Khan [PDF]
, 2018 I hope that this brief essay on the history of the Mongolian state and nation has clarified a few points. I have tried to demonstrate that conceptually state and nation are not interchangeable and each deserves to be treated in its own right.

Deep Underground Science and Engineering, EarlyView.Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...

Locking Fe Single Atoms Into the Lattices of Mesoporous TiO2 Promotes Nitrogen Reduction
EcoEnergy, EarlyView.S‐coordinated Fe single‐atom catalysts on mesoporous TiO2 have been constructed by a universal lattice‐confined strategy. This catalyst shows a unique nanoconfinement effect for mass transfer and maximizes the active sites to mimic nitrogenase for ambient electrocatalytic N2 reduction reaction.
