Finite element analysis of magnetic materials allows accurate prediction losses and is crucial in the design electromagnetic devices products. Soft composites are an alternative to silicon steel laminations, yet material properties less well documented include uncertainties which can lead inaccurate iron Joule loss computations. The microstructure soft composites, based on ferromagnetic particl...

This article presents a soft pneumatic bending actuator using a magnetically assisted bilayer composite composed of silicone polymer and ferromagnetic particles. Bilayer composites were fabricated by mixing ferromagnetic particles to a prepolymer state of silicone in a mold and asymmetrically distributed them by applying a strong non-uniform magnetic field to one side of the mold during the cur...

The magnetoresistance Rxx was investigated in arrays of abutted square cavities with lengths L ranging from 500 nm to 1.2 mm near filling factor n ­ 1y2. Maxima in Rxx occur for effective magnetic field values satisfying the magnetic focusing condition between the cavity spacing and the cyclotron radius of composite fermions, also for the effective magnetic field direction when composite fermio...

Abstract Soft magnetic materials are key for the cores used in motors and generators. To improve energy efficiency of cores, it is important to understand mechanism loss under oscillating fields. Here, we clarify nanocrystalline soft (NSMMs), which candidates energy-efficient cores. investigate an NSMM, necessary consider interaction between magnetization crystal lattice, i.e., magnetostriction...

A new class of LC-resonators for micro-magnetic sensor device was invented and fabricated by means of micro-electromechanical system (MEMS) technique. The micro-LC-resonator consists of a solenoidal micro-inductor with a bundle of soft magnetic micro-wire cores and a capacitor connected in parallel to the micro-inductor. The core magnetic material is a tiny glass-coated Co83.2B3.3Si5.9Mn7.6 mic...

Design and application of powder composite electrodes for electrosynthesis and electroanalysis research has been carried out. The physical characterization of electrodes was analysis using SEM, EDX and FTIR. The electrochemical stability was analysis using cyclic voltammetry. The stability of electrodes was analyzed using Atomic Absorption Spectroscopy (AAS). The powder composite electrodes wer...

A nano-composite powder composed of silica and carbon with a unique property could be prepared from a mixture of a silicate compound and an epoxy compound, in which the silica within the nano-composite powder has a BET surface area of as high as greater than 800m2/g although the nano-composite powder has a BET surface area of less than 10m2/g. It was estimated that the silica and the carbon are...

Magnetic nanoparticles (MNPs) are very important systems with potential use in drug delivery systems, ferrofluids, and effluent treatment. In many situations, such as in biomedical applications, it is necessary to cover inorganic magnetic particles with an organic material, such as polymers. A superparamagnetic nanocomposite Fe3O4/poly(maleic anhydride-co-acrylic acid) P(MAH-co-AA) with a core/...
