Plasma-gas condensation cluster deposition systems have been introduced and applied for preparation of Co/CoO Co/Siclusters assemblies. In assemblies prepared by the single source PGC system with introduction O2 gas into chamber, fcc Co cores are covered NaCl type CoO shells, showing marked enhancement unidirectional uniaxial magnetic anisotropy a clear cross-over phenomenon in relaxation from high temperature thermal regime to low temperarure quantum tunneling regime. Co/Si double system,...
Three dimensional (3D) ZnO/ZnAl2O4 nanocomposites (ZnnAl-MMO) were synthesized by a simple urea-assisted hydrothermal process and subsequent high-temperature calcination. The as-prepared samples their precursors characterized X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission (TEM), UV-Vis diffuse reflectance spectroscopy (DRS), Photoluminescence spectra (PL). It was observed that the morphology of ZnnAl-MMO could be tuned from cubic aggregates, hierarchically...
Bismuth nanoparticles (BiNPs) and Zinc Oxide photocatalysts (BiNPs/ZnO) with different Bi loadings were successfully prepared via a facile chemical method. Their morphology structure thoroughly characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission (HRTEM), photoelectron spectroscopy (XPS), UV-Vis (Ultraviolet-Visible) diffuse reflectance (DRS), photoluminescence spectra (PL), electrochemical impedance (EIS). The results showed that...
Highly ordered arrays of parallel Fe70Co30 nanowires with a diameter about 50 nm and length up to several tens micrometers were synthesized by two electrical fields in an anodized aluminum oxide film. The magnetic properties the temperature range from 5 300 K studied. When applied field is along long axis, dependence coercivity nanowire shows linear decrease increasing, which can be understood phenomenological nucleate model.
Concomitant formation of metallic Bi nanoparticles and oxygen vacancies was successfully achieved within Bi/BiOBr/RGO composites by green UV-light exposure.
Abstract Non-specific biofilm formation (biofouling) commonly occurs to the surface of biomedical devices, which causes infection human tissues and function loss after implantation. To enhance antifouling properties on bioinert hydrogel-based biomaterials, a novel grafting approach was developed using radical chain-transfer reaction mediated by DL-dithiothreitol (DTT), rather than catalyzed cytotoxic metal ions. Zwitterionic poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) brushes were...
Abstract A series of Co nanocluster-assembled films with cluster sizes ranging from 4.5 nm to 14.7 were prepared by the plasma-gas-condensation method.

Oxide-coated metal (Co, Cr and Ti) cluster assemblies whose mean sizes are 8–13 nm have been fabricated by a plasma-gas-condensation type beam deposition technique. With increasing oxygen gas flow rate R, the oxide-coated cluster-assembled films exhibit metal–nonmetal transition. In metallic regime, resistivity reveals ln T dependence at low temperature due to weak localization of conduction electrons and/or electron–electron interactions in disordered films. The still remains for very thick...
