Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Chitin‐Chitosan Cryogels for the Reversible Sequestration and Recovery of Heavy Metals From Wastewater

Advanced Materials Technologies, EarlyView.
Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

Underground mine stream crossing assessment: A multi-disciplinary approach

International Journal of Mining Science and Technology, 2021
Underground mine designs typically try to avoid extraction beneath streams and rivers of any significant size, especially when the overburden rock thickness between the stream bed and the mine is thin. Potential issues with mining beneath streams include
