Preparation and Application of Copper Oxide Nanoparticles

Chang M-H, Tai C.Y-D, National Taiwan University, TW

The aim of this research was to synthesize copper oxide (CuO) nanoparticles, which were further applied to prepare CuO-water nanofluid, using a spinning disk reactor (SDR). The precursor of copper oxide was first synthesized by [...]

Adhesion of Water on Flat Polymer Surfaces and Superhydrophobic Surfaces

Law K-Y, Zhao H., Samuel B., Xerox Corporation, US

The interaction of water droplet with flat polymer surfaces of varying hydrophobicity (contact angle) has been studied using a high-sensitivity microelectromechanical balance system (tensiometer). Both attractive force and pull-off force are studied as the water [...]

Preparation of Silver Nanoparticles via Ionomer Clusters

Atorngitjawat P., Pipatpanyanugoon K., Faculty of science, Burapha University, TH

Silver nanoparticles can be prepared via the cluster of ionomer templates, which is a simple, fast and economical technique. The lower of acid levels of ionomers provided the smaller size of silver nanoparticles. Furthermore, using [...]

A facile low-temperature route for preparing monodisperse Mn3O4 nanopolyhedrons from amorphous MnO2 nanoparticles

Ma J., Zhang S., Liu W., Zhao Y., University of Shanghai for Sci& Tech., CN

In the paper, we firstly show a facile hydrothermal route for synthesizing monodisperse Mn3O4 nanopolyhedrons directly used new-made amorphous MnO2 nanoparticle with its mother solution as precursors. The hydrothermal process was performed at 160 ºC [...]

Transport of large Particles and Macromolecules in Flow Through Inorganic Membrane

Imdakm A.O., Matsuura T., University of Ottawa, CA

The influence of transport of large particles and macromolecules on membrane separation efficiency and permeation rate limitation has been observed in many separation processes of microscopic scale. In this paper a Monte Carlo simulation model [...]

From Micro to Nano Magnetic Spheres: Size-Controllable Synthesis, Multilayer Coatings, and Biomedical Applications

Leung K.C.F., Xuan S., The Chinese University of Hong Kong, HK

Magnetic material has become a particular important research area and is attracting a great deal of attentions because of their potential technological applications, such as in ferrofluids, colored pigments, high-density magnetic recording media, chemical sensors, [...]

Luminescent mechanism of bulk and nano ZnS:Mn2+ phosphors

Biggs M.M., Ntwaeaborwa O.M., Swart H.C., Hoffman M.J.H., University of the Free State, ZA

In this study ZnS nanophosphors, with or without different concentrations of Mn2+ activator ions, were synthesized by using the chemical precipitation method. Luminescent properties of the samples were determined by photoluminescence (PL) measurements. Two peaks [...]

Combustion synthesis and Magnetic Characterizations of Mn Substituted Ni–Zn Ferrite Nanoparticles

Mane D.R., Birajdar D.D., Shirsath S.E., Kadam R.H., Shrikrishna Mahavidyalaya, IN

The ferrite samples synthesized by sol–gel auto combustion method using nitrates of respective metal ions. An analysis of X-ray diffraction patterns reveals the formation of single phase cubic spinel structure. Nano size of the particle [...]

Magnetite particle size dependence on the co-precipitation synthesis method for protein separation
