Locking Ni Atoms in Ordered PtNi for Durable Hydrogen Production: From Electrocatalyst Design to Practical AEMWE Stack Validation

Carbon Energy, EarlyView.
DFT‐guided atomic ordering of PtNi intermetallic catalysts enhances HER activity and durability by optimizing hydrogen adsorption and increasing dissolution potential. Experimental validation from half‐cell to practical AEMWE stack demonstrates outstanding performance with less than 2% degradation over 3,000 h.

A Electromagnetic Theory of Earth's Rotation, Monsoons, and Geological Phenomena

This manuscript proposes a novel hypothesis that a continuous low-voltage electric current circulates through Earth's internal structure, contributing to geophysical phenomena such as Earth's sustained rotation, monsoonal irregularities, mountain and island formation, and the occurrence of earthquakes and volcanoes.

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Textual Tectonics in “The Man Who Died” by D. H. Lawrence

Journal of the Short Story in English, 2022
This article studies how D. H. Lawrence’s rewriting of the story of Christ’s resurrection operates along the textual fault-lines between the Bible and the novella “The Man Who Died” (1929), also known as “The Escaped Cock.” While Lawrence’s narrative ...

Review and prospects of shear test of bolted rock joints

Deep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

Deep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...
