Hierarchically Engineered Transition Metal Electrode for Direct Lithium Extraction From Brine

open access: yesCarbon Energy, EarlyView.
Carbon‐modified WO3 nanoparticles deliver lithium extraction from simulated brine with Li+ capacity of 3 mmol Li g−1h−1 and 43% recovery efficiency. Reduced graphene oxide enhances charge transport and interfacial stability, while reversible W redox validated by in‐situ spectroscopy, governs lithium intercalation dynamics and structural stability ...

Mechanical and environmental evaluation of ground calcium carbonate (CaCO3) filled polypropylene composites as a sustainable alternative to virgin polypropylene

open access: yesResults in Materials
Polypropylene (PP) has raised environmental concerns particularly for its depletion of fossil-fuels and contribution to climate change. To lower environmental impacts, PP can be combined with biobased fillers such as calcium carbonate (CaCO3).

Fe–Mn Heterojunction Modulated Electronic Environment for Enhanced CO2 Capture and In Situ Conversion

open access: yesCarbon Energy, EarlyView.
Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and

Nichtlineare Staubungsneigung binärer Schüttgutmischungen: Herausforderungen bei der Prognose Non‐linear dusting tendency of binary bulk material mixtures: Challenges in prognosis

open access: yesChemie Ingenieur Technik, EarlyView.
Aufgrund überlagerter oder konkurrierender Mechanismen sind relevante Wechselwirkungen bei der Staubung von Schüttgutmischungen komplex und nur unzureichend verstanden. Selbst für Mischungen aus umfassend charakterisierten Einzelkomponenten existieren keine belastbaren Modelle. In dieser Arbeit werden die Hürden bei der Prognose thematisiert.

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
