Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking
Advanced Science, Volume 13, Issue 56, 9 October 2026.The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Experimental methods in chemical engineering: Magnetometry
The Canadian Journal of Chemical Engineering, Volume 104, Issue 10, Page 5176-5188, October 2026.Abstract Magnetometry is a non‐invasive technique to characterize the behaviour of magnetic materials of which the most common contain Fe, Co, and Ni. Vibrating sample magnetometers (VSMs) vibrate samples at a fixed frequency in a static, homogeneous magnetic field to induce a voltage in pick up coils according to Faraday's law of induction.

Phase Transformation and Particle-Mediated Growth in the Formation of Hematite from 2‑Line Ferrihydrite [PDF]
, 2016 Iron oxide nanoparticles are present throughout the Earth and undergo mineral phase transformations that affect their stability and reactivity. The formation of the iron oxide hematite from a 2-line ferrihydrite (2lnFh) precursor requires both phase ...

Water Resources Research, Volume 62, Issue 10, October 2026.Abstract Groundwater contamination has become an increasingly critical environmental concern worldwide. In situ chemical oxidation (ISCO) is considered a promising technology for groundwater remediation, but its performance in heterogeneous aquifers is often constrained by mass‐transfer limitations in low‐permeability zones, leading to suboptimal ...

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems
Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...
