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

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Do CSR Committees Moderate the Relationship Between Democratic Societies and Firm Innovation? An International Overview

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The purpose of this study is to provide evidence of the impact of civil liberties and political rights on corporate innovation, through the lens of institutional theory. Moreover, the research also analyses the moderating role of the CSR committee in the relationships between civil liberties and innovation, and political rights and innovation.

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

open access: yesEcography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...

Intramolecular Matere Bonds in Isostructural Rubidium (18‐Crown‐6) Pertechnetate and Perrhenate Dimers

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Two rubidium cations that are not fully encapsulated by 18‐crown‐6 are bridged by two pertechnetate units to form a dimer. These two pertechnetate units are nearly linearly aligned to each other to form Matere bonds (MaBs), a type of noncovalent σ‐hole interaction.
