Carbon Energy, EarlyView.The present review discusses the advancement in the catalytic synthesis of 5‐alkoxymethylfurfural (AMF) and levulinate esters (LEs) from the aspects of catalytic systems, reaction mechanisms, product isolation, and techno‐economic analysis, supplying valuable insights toward future sustainable and efficient manufacture of AMF and LEs. ABSTRACT The huge

Chemistry – A European Journal, EarlyView.A family of amino‐acid–derived MOFs enables ultrafast (>90–95% in 30 s) simultaneous removal of four estrogenic contaminants from water under SPE conditions. A leucine‐based MOF shows excellent regenerability and robustness in real samples, with structural evidence revealing efficient hormone encapsulation.

Decolorization of Disperse Dyes in Textile Polyester Recycling Using Activated Carbon
Chemie Ingenieur Technik, EarlyView.Decolorization of disperse dyes from disodium terephthalate solutions is examined using two activated carbons with varying pore structures and surface properties. The potential impact of pore size distribution and surface charge on the adsorption process is assessed to support optimized adsorbent selection.

Nocardia effects in waste activated sludge
Water Science and Technology, 1998 Two effects of Nocardia in waste activated sludge (WAS) were investigated: (i) the influence of WAS in the solids treatment recycle streams on Nocardia persistence in the activated sludge, and (ii) the effect of Nocardia in WAS on anaerobic digester foaming.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C
