High H2S gas sensitivity was improved by electrochemically engineering Co3O4/CoO heterostructures with oxygen vacancies and aligning nanosized particles via magnetic‐field‐assisted deposition. This alignment enhanced gas diffusion and electron transport, reducing base resistance. The resulting sensor exhibited high selectivity and a strong response (Rg/

Abstract Self‐reversed magnetization, acquired antiparallel to the external field, can complicate the interpretation of paleomagnetic directional records, particularly in altered greigite‐bearing sediments with anomalous magnetizations. The underlying physical process for this self‐reversal remains poorly constrained.

The effect of polycations on the formation of magnetite nanoparticles
Nanoparticles of magnetite (Fe3O4) are envisioned to find used in diverse applications, ranging from magnetic data storage, inks, ferrofluids as well as in magnetic resonance imaging, drug delivery, and hyperthermia cancer treatment. Their magnetic properties strongly depend on their size and morphology, two properties that can be synthetically ...

Synthesis and Properties of MPEG-Coated Superparamagnetic Magnetite Nanoparticles
The magnetite nanoparticles were synthesized by the thermal decomposition of iron(III) acetylacetonate in methoxy polyethylene glycol, which was used as solvent, reducing agent, and modifying agent in the reaction. The morphologies and phase compositions
