Energetics of Lithium Insertion into Magnetite, Defective Magnetite, and Maghemite

Chemistry of Materials, 2018
At low concentrations of lithium insertion into inverse spinel magnetite Fe3O4, a phase change to rock-salt-like LixFe3O4 has been observed. We used density-functional-theory-based (DFT-based) calculations to study the structural origins of this phase change, the concentration at which it occurs, the role of iron vacancies, and the stability of the ...

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.

Enhancement of Pb and Cd Adsorption in Water Samples by Magnetite Using Humic Acid as Modifier

Yankuang ceshi, 2019
BACKGROUND Magnetite is widely used as a green and cheap mineral material to adsorb heavy metals in water samples, but it has the disadvantages of low adsorption capacity, poor selectivity and easy reunion.

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 ...

Size-dependent magnetic responsiveness of magnetite nanoparticles synthesised by co-precipitation and solvothermal methods

Journal of Science: Advanced Materials and Devices, 2018
The dependence of the magnetic responsiveness on magnetite nanoparticle size has been studied. Monodisperse magnetite nanoparticles of 10 nm diameter were prepared by an ultrasonically enhanced co-precipitation procedure.

Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.
