Bimagnetic FePt/CoFe2O4 nanoparticles having a bricklike morphology were synthesized by growing a soft magnetic CoFe2O4 phase on FePt cubic nanoparticle seeds. The size of the soft phase could be controlled by tuning the material ratio of the FePt seeds to the CoFe2O4 component. To obtain magnetic hardening, the as-synthesized bricklike nanoparticles were annealed at elevated temperatures under...

Iron cobalt oxides, such as typical FeCo2O4 and CoFe2O4, are two spinel structured transitional metal oxide materials with excellent electrochemical performance. As the electrodes, they have been widely applied in the current energy storage and conversion processes such as supercapacitors, Lithium-ion batteries and fuel cells. Based on synthesis approaches and controlled conditions, these two m...

Nanocomposite of CoFe2O4/SrFe12O19 has been synthesized by the electrospinning and calcination process. A novel method that cobalt powder was used to replace traditional cobalt salt in the precursor sol-gel for electrospinning was proposed. The crystal structures, morphologies, and magnetic properties of these samples have been characterized in detail. Moreover, when the average crystallite siz...

IL-32, a recently discovered proinflammatory cytokine with four isoforms, induces IL-1beta, TNF-alpha, IL-6, and chemokines. Here, we used ligand (IL-32alpha) affinity chromatography in an attempt to isolate an IL-32alpha soluble receptor or binding protein. Recombinant IL-32alpha was covalently immobilized on agarose, and preparations of concentrated crude human urinary proteins were applied f...

We discuss the atomic structure of cobalt ferrite nanoparticles doped with Mn via an analysis based on combining pair distribution functions high energy X-ray diffraction and high-resolution transmission electron microscopy measurements. Cobalt are promising materials for metal–air battery applications. ferrites, however, generally show poor electronic conductivity at ambient temperatures, whic...

Due to their narrow homogeneous linewidths, rare-earth ions in inorganic crystals at low temperatures have recently been given considerable attention as test materials for experiments in coherent quantum optics. Because these narrow linewidth transitions have been buried in a wide inhomogeneous line, the scope of experiments that could be carried out in these materials has been limited. However...

Antineutrophil cytoplasm autoantibodies with specificity for proteinase 3 (PR3) are thought to play a major role in the pathogenesis of Wegener's granulomatosis (WG), presumably by their potential to activate neutrophils. In patients with WG, high expression of PR3 on the surface of nonprimed neutrophils is associated with an increased incidence and rate of relapse. In this study, we analyzed t...
