Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.

Bidentate‐Ligand Molecular Bridge in NiFe‐LDH as a Dynamic Proton Relay and Electronic Modulator to Enhance the Oxygen Evolution Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
By introducing 4‐chlorobenzoic acid ligands into the interlayer of NiFe‐LDH, the carboxyl and Cl groups on either side are respectively bonded to nearby Fe atoms, yielding a stable Bridge‐Linked structure. The strong electron interaction between the ligands and metal ions suppresses metal ion leaching during the reaction process, thereby maintaining ...

A Novel Bipolar DC Connection Strategy for Photovoltaic Power Plants With a 50% Reduction in DC Cabling Length

Energy Science &Engineering, EarlyView.
Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China

Energy Science &Engineering, EarlyView.
This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...
