The efficacy of the banana peel (Musa sapientum) biomass was tested for the removal of lead, copper, zinc and nickel metal ions using batch experiments in single and binary metal solution under controlled experimental conditions. It is found that metal sorption increases when the equilibrium metal concentration rises. At highest experimental solution concentration used (150 mg/L), the removal o...

Four heteroleptic complexes of nickel(ii), cobalt(ii) and zinc(ii), containing a monodentate silanethiolate ligand derived from tris(2,6-diisopropylphenoxy)silanethiol (TDST), were prepared and characterized. Nickel(ii) and cobalt(ii) complexes of the formula M(NH3)2(TDST)2 (M = Ni(ii) complex , M = Co(ii) complex ) were obtained from the respective chlorides. Zinc complexes of the general form...

Polyaniline-NiFe2O4 nanocomposites (PANI-NiFe2O4) with different contents of NiFe2O4 (2.5, 5 and 50 wt%) were prepared via in situ chemical oxidation polymerization, while the nanoparticles nickel ferrite were synthesized by sol-gel method. The prepared samples were characterized using some techniques such as Fourier transforms infrared (FTIR), X-ray diffraction (XRD), scanning electron microsc...

Title of Document: NANOSTRUCTURED NICKEL-ZINC MICROBATTERIES USING THE TOBACCO MOSAIC VIRUS Konstantinos Gerasopoulos, Master of Science, 2008 Directed By: Professor Reza Ghodssi, Department of Electrical and Computer Engineering The development of nanostructured nickel electrodes using the Tobacco mosaic virus (TMV) for microbattery applications is presented in this Thesis. The TMV is a high a...

HPMC Polymer composites were prepared by doping various concentrations of Zinc ferrite nanoparticles using solution casting method. These polymer composites were characterized using X-Ray Diffraction and conductivity measurements. The addition of nanoferrites in the polymer matrix do change the structural and the AC conductivity properties of the film, which is supported by the results obtained...

Applications of magnetostrictive materials, such as sensors and energy-harvesting devices, generally involve the use dynamic deformation, i.e., piezomagnetic effect, induced by an exciting magnetic field H ac . However, this effect is rarely measured directly but commonly approximated strain der...

Anisotropic nano-plate structures in self-assembled perovskite-spinel thin films, BiFeO3-NiFe2O4 and BiFeO3-CoFe2O4, which were deposited on (001)c SrRuO3/SrTiO3 and DyScO3 substrates, respectively, have been demonstrated using transmission electron microscopy combined with strain analysis. Unlike the unitary cube-on-cube orientation relationship reported widely, the growth direction of the CoF...

We report a novel core-shell-structured ternary nanocube of MnZn ferrite synthesized by controlling the reaction temperature and composition in the absence of conventionally used reducing agents. The highly monodispersed core-shell structure consists of an Fe(3)O(4) core and an MnZn Ferrite shell. The observation of a Moiré pattern indicates that the core and the shell are two highly crystallin...

Multiferroic ceramic composites have been engineered to incorporate multiple desired physical properties within a single component. The objective of this study was create such through pressure less sintering ferroelectric-doped PZT and nickel–zinc ferrite at temperature 1250 °C. growth grains found be influenced by the concentration ferroelectric phase. Consequently, an increase in content decr...

The processes of melt formation were studied by methods optical and electron scanning microscopy. These occur during induction brazing a hard alloy to steel holder contact interaction low-melting (copper-zinc system alloy) refractory (iron-nickel) components the solders. It is shown that effect thermal magnetic-dynamic high-frequency electromagnetic field on composite solder how high-strength j...
