Harnessing Random Polymers as Chemoselective Catalysts With Structural Adaptability: Epoxidation of Olefinic Quaternary Ammonium Salts via Charge Recognition

open access: yesChemistry – A European Journal, EarlyView.
The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

A Strategic Action Plan to Advance Circular Economy Practices in the Automotive Industry Based on Sector Insights to Support Sustainable Development

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The circular economy is gaining traction as a transformative approach to address climate change and the shortcomings of the linear economic model, which is defined by unsustainable production and consumption patterns. This study explores the implementation of circularity principles in the Spanish automotive industry, with particular attention ...

Life Cycle Analysis as a Sustainable Governance Lever for Environmental Performance: Evidence From French SBF 120 Companies

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study draws on neo‐institutional theory, stakeholder theory, and the resource‐based view to examine the relationship between the use of Life Cycle Analysis (LCA) and firms' Environmental Performance (EP). Focusing on French companies listed on the SBF 120 index from 2002 to 2021, it investigates how LCA adoption influences EP across three
