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

AI‐Enhanced Laser Manufacturing: A Social Life Cycle Perspective From the White Goods Industry

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainable manufacturing transitions require companies to demonstrate not only environmental and economic benefits, but also measurable advances in corporate social responsibility (CSR). Therefore, we propose using a guideline‐based Social Life Cycle Assessment (S‐LCA) aligned with UNEP (2020) and ISO 14075 (2024) to evaluate the social ...

The effect of calcium and magnesium on the aggregation of a purple phototrophic bacteria mixed consortium

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND An essential aspect of applying Purple Phototrophic Bacteria (PPB) technology for wastewater treatment is the biomass separation from the aqueous phase. Ca2+ and Mg2+ have been used to enhance the aggregation of different biological matrices. In this paper, the effect of Ca2+ and Mg2+ on the aggregation of a mixed culture of PPB was

Use of predictive tools for the analysis of bioactive compounds in crocus SATIVUS L. flowers

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Crocus sativus L. (saffron) flowers have high bioactive potential because of their content of crocins, safranal and phenolic compounds. The development of predictive models based on near‐infrared (NIR) spectroscopy and partial least squares regression to estimate the antioxidant capacity of saffron flower, evaluated using oxygen ...

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

open access: yesOikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

Process‐Induced Anisotropy and Fracture Behavior of Pellet‐3D Printed PLA and PLA/Flax Biocomposites

open access: yesPolymer Composites, EarlyView.
Fused Granular Fabrication of PLA and PLA/flax biocomposites, followed by tensile testing and fracture surface analysis to evaluate the effects of raster orientation and layer number on anisotropy and fracture behavior. ABSTRACT Fused granular fabrication (FGF) enables cost‐effective, large‐scale polymer additive manufacturing; however, the mechanical ...
