A Multiphysics Finite‐Element Framework for Magnetically Tunable Electrochemical Hydrogen Sensors Based on Cs/GO/Fe3O4/PANi Hydrogels

Engineering Reports, Volume 8, Issue 3, March 2026.
A multiphysics finite‐element model is developed to elucidate magnetically tunable electrochemical hydrogen sensing in a Cs/GO/Fe3O4/PANi hydrogel nanocomposite. The framework couples hydrogen diffusion, electrochemical kinetics, charge transport, and superparamagnetic Fe3O4 alignment to predict sensor performance.

Ligand‐Driven Optimization of Iron Oxide Nanoprobes for In Vivo MRI Enhancement at Ultra‐High Field

Small, Volume 22, Issue 16, 17 March 2026.
Ligand‐tailored iron oxide nanoparticles reveal how surface chemistry controls T2 relaxivity and in vivo performance in ultra‐high‐field MRI. Systematic variation of hydrophilicity and charge across five coatings modulated r2 by up to 333 mm−1 s−1, with chemical properties, rather than shell thickness, dictating magnetic dephasing and enabling reliable
