Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

open access: yesCarbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

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

open access: yesThe 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

Hydrological and Thermal Dynamics of a Supra‐Permafrost Subterranean Estuary

open access: yesWater Resources Research
Subterranean estuaries (STEs), where groundwater interacts with seawater, influence surface and subsurface coastal ecology and biogeochemistry. In Arctic‐STEs overlying permafrost, groundwater flow and heat transport determine the fate of organic matter.
