Magnetocapacidad en nanopartículas de Fe3O4 y NiFe2O4

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2010
We have synthesized NiFe2O4 (φ∼ 6 nm) and Fe3O4 (φ∼ 30 nm) magnetic nanoparticles by solvothermal synthesis; furthermore the Fe3O4 nanoparticles have been coated with a SiO2 shell of approximately 5 nm of thickness by the Stöber method.

Sintering‐Driven Modulation of Lattice Dynamics, Elastic Behavior, and Dielectric Response in Al–Sn Co‐Doped Zinc Ferrite Nanoparticles

open access: yesAdvanced Physics Research, EarlyView.
Sintering ZnAl0.1Sn0.1Fe1.8O4 nanoparticles at 1200°C optimizes structural lattice dynamics, significantly enhancing both macroscopic elastic stiffness and high‐frequency dielectric response through synergistic Al3+ stabilization and Sn4+‐driven charge transport. ABSTRACT In this work, ZnAl0.1Sn0.1Fe1.8O4 (ZASFO) ferrites were synthesized via a sol–gel

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

Experimental Validation of a Spoke Type Ferrite Permanent Magnet Machine Design for Heavy‐Duty Traction Applications

open access: yesIET Electric Power Applications
Rare earth elements (REEs) are central to the current solutions used for traction applications. However, REEs have fragile supply chains, which exposes them to supply interruptions and price spikes.

Advancing Upcycling and Regeneration of Spent LiFePO4: Failure Mechanisms and Recovery Strategies

open access: yesCarbon Energy, EarlyView.
This review studies the failure mechanism to promote the upcycling regeneration of spent lithium iron phosphate (S‐LFP). It first summarizes the failure mechanisms of LFP batteries revealed via advanced characterization technologies and then explores the respective advantages and challenges of hydrometallurgy and direct regeneration methods.
