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 ...

Trace Mo Doping in NaMnO2 Cathode Materials for High‐Capacity Sodium‐Ion Batteries

Energy Science &Engineering, EarlyView.
Mo‐doping demonstrates great potential in promoting energy intensity. NaMn0.99Mo0.01O2 shows an average working voltage of 3.0 V and an initial capacity of 183.7 mAh g−1 at 0.2 C. It has a remarkable specific capacity of 138.1 mAh g−1 and 84.7% capacity retention over 100 cycles even at 1 C.

Damage Characteristics and Stress Distribution Law of Overburden Rock in Multiple Mining of Close Coal Seams

Energy Science &Engineering, EarlyView.
This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Recent Progress on Graphitic Carbon Nitride–Based Photocatalysts for Hydrogen Peroxide Synthesis

Exploration, EarlyView.
This review summarizes recent progress in using graphitic carbon nitride (g‐C3N4) photocatalysts to produce hydrogen peroxide (H2O2). It highlights how solar energy can cleanly convert water and oxygen into this valuable chemical. We discuss key modification strategies, such as defect engineering, doping, and junction construction, to enhance ...

Microbial Interventions in Processing of Plant Based Proteins: Unlocking Extraction Dynamics and Functionality for Human Health

Food Bioengineering, EarlyView.
Fermentation enhances nutritional & techno‐functional properties of plant protein. Three distinct stages of fermentation impact on different aspects of plant protein. Fermentation induces flavors modulation through new organic compounds formation. Plant protein fermentation improves their utility in food applications.
