Interferometric Scattering Microscopy (iSCAT): A Perspective on Visualizing and Engineering Electrode Homogeneity for Advanced Lithium‐Ion Batteries

Carbon Energy, EarlyView.
Electrode state‐of‐charge heterogeneity critically limits lithium‐ion battery performance and safety. This Perspective highlights iSCAT, a powerful optical technique for real‐time, nanoscale visualization of lithium dynamics within single particles. By revealing the origins of heterogeneity, iSCAT enables rational electrode design.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

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
