| 1 | 快速微波燃烧法制备的Cu-Ni合金纳米粒子结构和磁性能(英文)显示文摘采用微波燃烧法制备Cu2+和Ni2+摩尔比分别为3∶7,4∶6,5∶5,6∶4和7∶3的Cu-Ni合金纳米粒子,采用XRD、HR-SEM、EDX和VSM对所制备的样品进行表征.X射线衍射和能谱分析表明,在样品制备过程中形成了纯合金粉末.样品的平均晶粒尺寸为21.56~33.25 nm.HR-SEM像显示样品具有集群/团簇粒状形态结构.VSM分析结果表明,对于低Ni含量的合金(Cu5Ni5,Cu6Ni4和Cu7Ni3),样品显示顺磁性,而对于较高Ni含量的合金(Cu3Ni7和Cu4Ni6),样品呈现铁磁性. | J.ARUL MARY A.MANIKANDAN L.JOHN KENNEDY M.BOUOUDINA R.SUNDARAM J.JUDITH VIJAYA | 2014 | Transactions of Nonferrous Metals Society of China2014，24，5： | 4 |
| 2 | Co-Doped ZnO Nanoparticles:Structural,Morphological,Optical,Magnetic and Antibacterial Studies显示文摘Un-doped and Co-doped Zn O nanoparticles(NPs) with different weight ratios(0.5, 1.0, 1.5, and 2.0 wt% of Co)were synthesized by a facile and rapid microwave-assisted combustion method using urea as a fuel. The prepared NPs were characterized by X-ray diffraction(XRD), high resolution scanning electron microscopy(HR-SEM),energy dispersive X-ray analysis(EDX), diffuse reflectance spectroscopy(DRS), photoluminescence(PL)spectroscopy and vibrating sample magnetometry(VSM). XRD patterns refined by the Rietveld method indicated that Co-doped Zn O had a single pure phase with wurtzite structure suggesting that Co2 t ions would occupy Zn2 t ionic sites within the Zn O crystal lattice. Interestingly, the morphology was found to convert substantially from grains to nanoparticles with close-packed periodic array of hexagonal-like shape and then into randomly distributed spherical NPs with the variation of Co-content. The optical band gap estimated using DRS was found to be red-shifted from 3.22 e V for the un-doped Zn O NPs then decrease up to 2.88 e V with increasing Co-content. PL spectra showed a strong green emission band thus confirming the formation of pure single Zn O phase. Magnetic studies showed that Co-doped Zn O NPs exhibited room temperature ferromagnetism(RTFM) and that the saturation magnetization attained a maximum value of2.203 103emu/g for the highest Co-content. The antibacterial studies performed against a set of bacterial strains showed that the 2.0 wt% Co-doped Zn O NPs possessed a greater antibacterial effect. | N.Mohamed Basith J.Judith Vijaya L.John Kennedy M.Bououdina S.Jenefar V.Kaviyarasan | 2014 | Journal of Materials Science & Technology2014，30，11： | 1 |
