Interaction of magnetite-based receptors in the beak with the visual system underlying "fixed direction" responses in birds [PDF]

, 2010
Background: European robins, Erithacus rubecula, show two types of directional responses to the magnetic field: (1) compass orientation that is based on radical pair processes and lateralized in favor of the right eye and (2) so-called 'fixed direction ...

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 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 ...

Interaction between magnetite and inoculum characteristics in accelerating methane production kinetics

GCB Bioenergy
Magnetite nanoparticles can boost methane production via direct interspecies electron transfer. However, the combined effect of inoculum and particle characteristics on magnetite's methanogenesis stimulation is poorly understood.

Effect of magnetostatic interactions on the hysteresis parameters of single-domain and psuedo-single domain grains [PDF]

, 2003
From experiments it is known that magnetostatic interactions between grains strongly affect the magnetic behavior of samples. However, because of the difficulty in predicting the nonlinear behavior, the effect of interactions has been largely ignored ...

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.

Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

Magneto‐responsive fibers and fabrics for soft systems

FlexMat, EarlyView.
Abstract The combination of functional materials in fiber form has led to a surge in the integration of functional fibers and fabrics into soft systems that span sensing, communication, and actuation domains. A key subset is magnetic fibers and fabrics.
