Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides
Chemie Ingenieur Technik, EarlyView.Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Regulatory Convergence and Divergence in ESG Reporting in the Indo‐Pacific Region
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Environmental, social, and governance (ESG) reporting has evolved significantly globally over the past few decades. Many countries are now signatories to international agreements such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement, with increasing commitments to emissions reduction targets and the

Deep Underground Science and Engineering, EarlyView.This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Natural radioactivity levels (K, Th and Ra) in some areas of Punjab, India
EPJ Web of Conferences, 2012 Radioactivity, natural and man-made, is omnipresent in the earth's crust in different amounts. Natural radioactive materials under certain conditions can reach hazardous radiological levels.

Deep Underground Science and Engineering, EarlyView.The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.
