Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Data-Space Inversion with Ensemble Smoother

open access: yes, 2019
Reservoir engineers use large-scale numerical models to predict the production performance in oil and gas fields. However, these models are constructed based on scarce and often inaccurate data, making their predictions highly uncertain.

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep 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

2D/2D MOF‐Based S‐Scheme Photocatalyst for Enhanced H2 Production and Charge Transfer

open access: yesEcoEnergy, EarlyView.
An ultrathin 2D/2D MOF‐based S‐scheme heterojunction is constructed via pH‐mediated electrostatic self‐assembly, generating a built‐in electric field that accelerates interfacial charge separation while preserving strong redox potentials. This design enables highly efficient cocatalyst‐free photocatalytic hydrogen evolution.

Predicting oxygen thresholds of marine taxa to improve ecological forecasts

open access: yesEcography, EarlyView.
Species' ranges are shifting in response to increasing temperature and decreasing oxygen in coastal oceans. Predicting these shifts is limited by information on physiological oxygen thresholds and how they depend on temperature. Here we collate laboratory‐derived measurements of a common oxygen threshold, pcrit, for 148 animal species that span six ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.
