Spherical iron oxide nanocomposite particles composed of magnetite and wustite have been successfully synthesized using a novel method of pulsed laser irradiation in ethyl acetate. Both the size and the composition of nanocomposite particles are controlled by laser irradiation condition. Through tuning the laser fluence, the Fe3O4/FeO phase ratio can be precisely controlled, and the magnetic pr...

Development of new tools to improve the efficiency iron minerals in promoting Fenton oxidation for environmental remediation is a highly promising field. Here, we examine first time role ascorbic acid (AA) improving magnetite (Fe3O4)-mediated remove pentachlorophenol (PCP) historically contaminated soil. Experiments were performed batch and flow-through conditions. In slurry experiments, combin...

Grafting and stabilization of metal complexes for increasing catalytic activity have remained an enormous challenge in the arena. However, designing a system with complementary properties including high surface area, loading, easy separation offers promising route efficient utilization magnetic material various applications. Herein, novel core–shell nanosphere catalyst (Fe3O4@C/KP23@MnCl2) was ...

Chemically disordered B3–7-nm-diameter FePt nanoparticles are synthesized using the airless operation technique based on decomposition of iron pentacarbonyl and reduction of platinum acetylacetonate. The particle solution is then washed and subsequently deposited onto a thermally oxidized Si substrate. Nanoparticle assemblies are formed after solvent evaporation. The samples are heat-treated us...

Templated mineralization of virus particles provides routes to narrowly dispersed nanoparticles that are not readily prepared by other means. The templated mineralization of metal or metal oxide on the external surface of wild-type cowpea mosaic virus (CPMV), a plant virus, is facilitated by increasing the external surface negative charge. This is achieved by the chemical modification of surfac...

Iron nanoparticles encapsulated within graphene shells ([email protected]) were examined for cellular internalization, subcellular behavior, biocompatibility, and influence on cell viability proliferation. Studies human lung (adenocarcinoma alveolar basal epithelial) skin (epidermoid carcinoma) cells indicate [email protected] is less toxic more biocompatible than the magnetite coated by an amo...

Superparamagnetic iron oxide nanoparticles with appropriate surface modification can be widely used in various applications including magnetic resonance imaging (MRI) diagnostic contrast agents, anticancer therapy using hyperthermia, magnetic drug targeting, protein and enzyme immobilization, cell labeling and separation or RNA and DNA purification. All these biochemical and biomedical applicat...
