ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

European Journal of Organic Chemistry, EarlyView.A new photocatalyst for the aerobic photochemical oxidation of sulfides to sulfoxides is described under really low catalyst loading (0.01 mol%) and methanol as the green solvent. The chemoselective oxidation of sulfides to sulfoxides is accomplished using a new family of photocatalysts, namely 1,2,6‐thiadiazin‐4‐ones. Utilizing a low catalyst loading (

Coal desulfurization by chlorinolysis production and combustion test evaluation of product coals [PDF]
Laboratory-scale screening tests were carried out on coal from Harrison County, Ohio to establish chlorination and hydrodesulfurization conditions for the batch reactor production of chlorinolysis and chlorinolysis-hydrodesulfurized coals.

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle
steel research international, EarlyView.Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction
steel research international, EarlyView.Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in
