Ecotoxicity of nanoscale zero-valent iron particles – a review

open access: yesVigilância Sanitária em Debate: Sociedade, Ciência & Tecnologia, 2013
The use of nanoscale zero-valent iron particles (nZVIs) in the environmental remediation of water and soil is increasing. This increase is related to the higher reactivity and mobility of nZVIs compared with that of macro- or micro-sized iron particles ...

Advancing Biomass Valorization via Electrocatalytic Oxidation: Design Principles, Emerging Challenges, and Future Perspectives

open access: yesSusMat, EarlyView.
This review categorizes substrates for electrocatalytic biomass valorization by carbon chain length into C2–C3 alcohols, C5–C7 cyclic compounds, and Cn biopolymers. It identifies four universal catalyst design principles: optimizing intermediate adsorption, engineering synergistic multi‐type active sites, accelerating active‐site formation, and ...

Metalized Carbon Fiber Electrodes for High‐Performance Aqueous Redox Flow Batteries: The Dominance of Bismuth

open access: yesBattery Energy, Volume 5, Issue 6, November 2026.
Metal‐coated carbon fiber electrodes transform aqueous redox flow batteries by accelerating negative‐electrode redox kinetics, suppressing hydrogen evolution, and regulating metal plating. Standardized testing, operando mechanistic studies, and techno‐economic validation are essential for practical, scalable deployment.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Application of CFD in Nanoremediation Problems with Nanoscale Zero-valent Iron Particles

open access: yesChemical Engineering Transactions, 2023
TCE (Trichloroethylene) is a chlorinated solvent, known for its toxicity present in many underground water reservoirs and, as it is a less viscous and denser contaminant than water, it reaches the impermeable substrate of the reservoirs, remaining ...
