Growth of Carbon Nanotubes on Co(x)‐Ni(1‐x) Ferrites by Chemical Vapor Deposition and Performance on Catalytic Wet Peroxide Oxidation

open access: yesChemCatChem, Volume 17, Issue 16, August 18, 2025.
This study presents a sustainable approach for synthesizing carbon nanotubes (CNTs) via chemical vapor deposition (CVD) using polyolefins as model plastic waste as the carbon source and Ni─Co ferrite catalysts. The CNTs were applied in catalytic wet peroxide oxidation (CWPO) to degrade bisphenol A (BPA) and sulfamethoxazole (SMX), achieving efficient ...

Waste pickers in extended producer responsibility policies: A comparative analysis of Brazil and the European Union

open access: yesReview of European, Comparative &International Environmental Law, Volume 34, Issue 2, Page 352-364, July 2025.
Abstract This article presents a case study of extended producer responsibility (EPR) policies adopted by the European Union (EU) and Brazil. It focuses on waste pickers—a group increasingly visible in EU countries such as Spain and Italy. While EU directives emphasise the polluter pays principle, little attention is given to the role of informal ...

Polyolefin and Polystyrene‐Derived Carbon Nanotubes: Catalysts for Oxidative Desulfurization Under a Biphasic System

open access: yesChemCatChem, Volume 17, Issue 11, June 6, 2025.
Polyolefins and polystyrene, simulating plastic solid waste (PSW), are transformed into value‐added carbon nanotubes (CNTs) through chemical vapor deposition (CVD). The CNTs are then applied in the oxidative desulfurization (ODS) of dibenzothiophene (DBT) in the oil–water biphasic system, resulting in C─S cleavage, yielding sulfur‐free products ...

Green Startups Led by Young Entrepreneurs in Tunisia: Transforming the Future With Sustainable Innovation

open access: yesDigest of Middle East Studies, Volume 34, Issue 3, Summer 2025.
ABSTRACT The Arab Spring resulted in an expansion of social and individual freedoms in Tunisian society, but it also brought political instability, negatively impacting what had long been the country's primary source of employment—tourism. This economic crisis forced many to improvise their own sources of income, and it was in this context that a new ...

A Systems Thinking Approach to Nuclear Pedagogy and Workforce Development

open access: yesJournal of Critical Infrastructure Policy, Volume 6, Issue 2, Fall/Winter 2025.
ABSTRACT Nuclear technology's controversial status has been shaped by its early use in military applications, fear driven by high‐profile accidents, and unresolved waste management challenges. There have, on the other hand, been periodic claims that a “nuclear renaissance” is imminent, driven by different dynamics at different times, most recently ...
