Controlled oxidation of benzyl ether is established as a key synthetic parameter in the thermal decomposition of iron(III) acetylacetonate. Oxygenated solvent species alter precursor coordination and nucleation–growth kinetics, producing highly crystalline, magnetite‐rich nanoparticles with tunable size, controlled morphology, and near‐bulk ...

NiNb alloys enable efficient charge‐to‐spin conversion by combining the spin Hall effect of nickel with the orbital Hall effect of niobium. Composition tuning yields spin‐torque efficiencies of −1.4 to −1.7 and a non‐monotonic efficiency‐resistivity relationship, revealing orbital‐spin synergy beyond conventional spin Hall materials and offering a ...

Experimental methods in chemical engineering: Magnetometry
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.

Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.

ABSTRACT Magnetic particles coated with carbon shells have been considered as promising electromagnetic wave absorption materials with antibacterial features. However, how to precisely control the monodispersed magnetic nanoparticles on a carbon matrix to manipulate impedance matching and antibacterial performances is still a key challenge.

Research into methods of pipe end demagnetization under main pipeline repair
Efficiency of pipe end demagnetization methods is experimentally investigated to avoid arc magnetism at repair welding jobs on main pipelines. It is found that multi-polar biased static and dynamic demagnetization provides an acceptable level of magnetic

Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Abstract The Scourie dyke swarm in the Lewisian foreland of northwest Scotland provides key constraints on the Paleoproterozoic evolution of the North Atlantic craton. High‐precision U‐Pb geochronology identifies two distinct intrusive phases at ∼2.41–2.38 Ga and ∼2.00 Ga.
