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

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system
The Canadian Journal of Chemical Engineering, EarlyView.Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

EcoEnergy, EarlyView.An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)
