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.

Deep 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

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

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 ...

Study on Roof‐Control Technology for Gob‐Side Entry Retaining Under Composite Roofs
Energy Science &Engineering, EarlyView.This study develops a roof‐control technology system for gob‐side entry retaining under composite roofs. By integrating field measurements, theoretical analysis, and numerical simulation, it reveals the spatiotemporal evolution of the plastic zone and proposes a targeted support method, providing theoretical and practical guidance for safe and ...
