Synergistic extraction of critical metals from the oxalic leachate of spent FCC catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study introduces an improved hydrometallurgy process utilizing a synergistic approach to improve metal recovery from secondary sources of critical metals. It provides a more efficient alternative to traditional single‐extractant methods for separating critical metals from spent refinery catalysts.

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Advantages of Pulsed Laser Ion Source (LIS) at an Intensity of About 1010 W/cm2 for Heavy‐Ion Injection Into High‐Energy Accelerators

Contributions to Plasma Physics, EarlyView.
ABSTRACT At the Laser Plasma Physics laboratories of the University of Messina, an experimental platform for generating and accelerating low‐energy ions (keV) using pulsed lasers and for their potential applications has been put into operation. A Q‐switched Nd:YAG laser produces the beam for the system, operating at 1064 nm.

Enhanced Photocatalytic Antibiotic Micropollutants Removal Resulting From a Synergism Between Cu Single Atoms and Carbon Vacancies on Graphitic Carbon Nitride

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Scheme of the synergistic degradation for antibiotic micropollutants in the Cu/ag‐C3N4 system. Photocatalytic processes driven by visible‐light irradiation offer a sustainable means of micropollutants removal from aquatic environments without the addition of reagents.

Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.
