DC and AC dielectric properties transformer oil based magnetic fluid

Timko M., Kopcansky P., Tomco L., Marton K., Koneracka M., Herchl F., Tomasovicova N., Institute of Exprimental Physics SAS, SK
The comparison of the AC-dielectric breakdown strength of transformer oil based magnetic fluid with pure transformer oil confirmed better insulating properties of magnetic fluid in external magnetic field. The better heat transfer properties provided by [...]

Formation of Ni/NiO core/shell nanostructures and their attachment on carbon nanotubes

Chopra N., Claypoole L., Bachas L.G., University of Alabama, US
We report a facile wet synthesis method coupled with microwave irradiation to successfully control the morphology of Ni/NiO core/shell nanoparticles. Furthermore, we report for the first time, microwave-based synthesis of hollow NiO nanostructures from Ni [...]

Synthesis and Characterization of Silver Nanoparticle Rings Embedded in Glass

Chen Y., Jaakola J., Ge Y., Säynätjoki A., Tervonen A., Hannula S-P, Honkanen S., Helsinki University of Technology, FI
Ion exchange technique with photolithography-patterned metal mask is used to form silver nanoparticle patterns embedded in glass. Optical transmission measurement is performed to characterize the optical properties of silver nanoparticles. Atomic force microscopy (AFM) of [...]

Control of Nanoparticle on Nanofiber via Magnetic Electrospinning

Chung M., Lan J.W., Lin H-Y, Suen T.W., Cheng S.H., Southern Taiwan University, TW
Nanoparticles added into nanofibers produced by electrospinning can expand the functions of such fibers, and these nanoparticles can serve as vehicle for drugs in active drug delivery concept. Depending on the toxicity of these nanoparticles, [...]

Impedance of Nanoparticles Embedded Electrospun Nanofiber

Chung M., Lan J.W., Lin H-Y, Suen T.W., Cheng S.H., Southern Taiwan University, TW
Electrospinning produces nanofibers with diameters ranging from 100-500 nm under 10-20 KV at 10-20 cm distances, and if these nanofibers were composed of polymers like PVA or PVP, they are usually nonconductive with resistances too [...]

Effect of Particle Morphology and Content on the Properties of Palladium/Polycarbonate Nanocomposites

Onbattuvelli V.P., Atre S.V., Ostroverkhova O., Pillai V.K., Oregon State University, US
Influence of Pd particle size and Pd content on the properties of the Pd/PC nanocomposites was investigated. Nanocomposites with varying Pd content were synthesized via the ex situ and in situ methods. Discrete Pd nanoparticles [...]

Preparation and Characterization of Polyimide-Cobalt Ferrite Nanocomposite

Mazuera D., Cedeño Y., Perales-Perez O., Singh S.P., University of Puerto Rico-Mayagüez, PR
Synthesized 20 nm cobalt ferrite single crystals, which exhibited a coercivity of 2.9kOe at room-temperature, were dispersed in precursor polyamic acid at different volume fractions and cured at 300oC to develop the polyimide matrix. Polyamic [...]

Nickel ferrite Nanomaterials by Pulsed laser ablation in Water; Structural, Optical and Magnetic Characterizations

Gopal R., Singh S.C., Swarnkar R.K., Allahabad University, IN
Nickel ferrite nanoparticles are synthesized by pulsed laser ablation of corresponding bulk target in the double distilled water. Focused output of fundamental and third harmonics from pulsed Nd:YAG laser operating at 40 and 25 mJ/pulse [...]

Quantum Dot (QD) gate Si-FET with Self Assembled GeOX Cladded Germanium Quantum Dots

Gogna M., AlAmoody F., Karmakar S., Papadimitrakopoulos F., Jain F., University of Connecticut, US
This paper presents preliminary data on the transfer and output characteristics of a GeOXcladded Ge quantum dot (QD) gate Si MOSFET. The MOSFET is formed by depositing cladded QDs above the SiO2 gate insulator formed [...]

Exposure modeling of engineered nanoparticle

Som C., Mueller N.C., Sonderer T., Gottschalk F., Scholz R., Nowack B., Empa Materials Science and Technology, CH
An elementary step towards a quantitative assessment of the risks of new compounds to the environment is to calculate their predicted environmental concentrations (PEC). The aim of this study was to use a life-cycle perspective [...]
