Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Activation of persulfate using a biochar polyacrylic acid composite loaded with nanoscale zero-valent iron for the in situ remediation of anthracene-contaminated soil

Green Energy & Environment
Synthesizing highly efficient, low-toxicity catalysts for the remediation of polycyclic aromatic hydrocarbons (PAHs) contaminated soils is crucial. Nanoscale zero-valent iron (n-ZVI) is widely used in the treatment of pollutants due to its high catalytic

Dynamic Chloride‐Ion Adsorption on Ag Nanoparticles and Carboxylic Acid Ligands: Enabling Highly Stable Industrial‐Scale Seawater Oxidation

EcoEnergy, EarlyView.
We propose a strategy where trimesic acid (TA) is anchored between LDH layers, enabling Ag nanoparticles to preferentially adsorb free Cl− to form AgCl. By modulating the charge environment within LDH layers, both chlorine corrosion resistance and OER activity are enhanced, enabling long‐term stable operation under industrial conditions.

Role of vertex corrections in the matrix formulation of the random phase approximation for the multiorbital Hubbard model

, 2016
In the framework of a multiorbital Hubbard model description of superconductivity, a matrix formulation of the superconducting pairing interaction that has been widely used is designed to treat spin, charge and orbital fluctuations within a random phase ...

Entropy‐Driven Design of Stable High‐Performance Sodium‐Ion Battery Cathodes

EcoEnergy, EarlyView.
This review explores high‐entropy strategies for advanced sodium‐ion battery cathodes, focusing on LTMOs and PBAs. It details how entropy engineering mitigates challenges: phase transitions, interface degradation, and air instability in LTMOs; vacancy defects and crystalline water in PBAs.
