Magnetic characteristics of FePt nanodots formed by a self-assembled nanodot deposition method

Yin C.K., Choi H., Bea J.C., Murugesan M., Yoo J-H, Fukushima T., Murakami Y., Tanaka T., Shindo D., Miyao M., Koyanagi M., Tohoku University, JP

FePt nanodot with L10 fct structure has attracted considerable attention owing to its potentials for new applications. FePt nanodots dispersed in a SiO2 film (FePt nanodot film) were formed by a self-assembled nanodots deposition (SAND) [...]

Magnetically Controlled Valve for Flow Manipulation in Polymeric Microfluidic Devices

Gaspar A., Piyasena M.E., Gomez F.A., California State University Los Angeles, US

Microfluidic devices (MDs) have emerged as novel analytical tools in many areas of science and industry. Their inherent qualities such as low power requirements, low sample consumption, rapid and parallel analysis, and automation provides unique [...]

Nano-Engineering Of Magnetic Particles For Biocatalysis And Bioseparation

Yu C.H., Lo C.C.H., Yeung C.M.Y., Tam K., Tsang S.C., University of Reading, UK

Magnetic nanoparticles encapsulated in a thin coating as magnetic separable nano-vehicle for chemical species is a hot but challenging area. The stability of the small magnetic body remains a key issue. In this meeting, we [...]

Novel Method for the Electrochemical Synthesis of Nickel-Rich Oxide Nanowires

Thorne S.A., Bhargava Y.V., Mintz T.S., Radmilovic V., Suzuki Y., Devine T.M., University of California-Berkeley, US

Using a novel electrochemical process, functionalized and self-assembled Ni-rich oxide nanowires were grown from an Alloy 600 (Ni – 15.5 a/o Cr, 8a/o Fe) substrate. The formation of the nanowires occurs in a high-temperature (238-288 [...]

Novel Magnetic Separable Nano-Carriers For Chemical Catalysis & Bio-Catalysis

Tsanga S.C., Tamb K., Gaoa X., Yua C.H., Yua K.K.M., Yeunga C.M.Y., Yua C.H., Yua K.K.M., University of Reading, UK

Separation of nanosize catalyst from product in liquid phase has been a major problem in industry. Thus the facilitated separation of a small magnetic body carrying catalytically active species is of a tremendous interest however; [...]

Synthesis and Properties of Magnetic Nanoparticles with Potential Applications in Cancer Diagnostic

Neamtu J., Jitaru I., Malaeru T., Georgescu G., Kappel W., Alecu V.-V., National Institute for Research, RO

The size, shape and composition of magnetic nanoparticles are very attractive for diagnostic tools of cancer tumors and targeting treatment in HIV infection. The goal of this paper is the preparation from colloidal solutions of [...]

Synthesis of Magnetic Nanocomposite Gels for Ophthalmic Applications

Haik Y., Chatterjee J., Chen C-J., Biomagnetic Engineering Lab, Tallahassee, US

Retinal detachment is estimated to cause 150,000 (in the United States alone) to be blind every year. Many detached retinas occur in older people. It occurs when the vitreous gel that adheres to retina shrinks [...]

Analytical Modeling of Beam Behavior Under Different Actuations

Sarraute E., Dufour I., URA CNRS 1375, FR

The aim of this paper is to establish simple analytical equations of the beam deflection for different actuation methods (magnetic with current, magnetic with magnet, electrostatic and piezoelectric). The analytical formulae are obtained from the [...]

Accurate Inductance Extraction with Permeable Materials Using Qualocation

Massoud Y., Wang J., White J.K., Massachusetts Institute of Technology, US

In this paper we present a more accurate method for solving a frequency-dependent inductance of 3-D structures that contains permeable materials. The extracted inductance using the new method is much more accurate than when using [...]

Fast Inductance Extraction of 3-D Structures with Non-Constant Permeabilities

Massoud Y., White J.K., Massachusetts Institute of Technology, US

In this paper we present a discretized integral formulation for calculating the frequency-dependent inductance and resistance for 3-D structures that contains permeable materials. The method uses a magnetic surface charge formulation, and we present analytic [...]
