Low-Temperature Polyol Synthesis of Nanocrystalline Co and CoPt Alloys

Chávarri-Pajares E., Pérez J., Perales-Perez O., Singhal R., Tomar M.S., University of Puerto Rico, PR

The strong size-dependent magnetic properties of transition metal nanocrystals can be used to estimate the scaling limits of magnetic storage, a key component of information technology. High Ku (magnetocrystalline anisotropy constant) materials become then very [...]

Conjugates of Enzyme-Magnetic Nanoparticles for Bioremediation*

Qiang Y., Sharma A., Paszczynski A., Meyer D., University of Idaho, US

Enzymes are proteins that function as biocatalysts in bioremediation. One of the major concerns in environmental applications of enzymes is their short lifetime. Enzymes lose their activity due to oxidation, which results in less stability [...]

Femtosecond laser micromachining of IC for semiconductor defect analysis

Halbwax M., Sarnet T., Hermann J., Delaporte Ph., Sentis M., Fares L., Haller G., LP3 UMR CNRS 6182, FR

The detection and analysis of defects in Integrated Circuits (IC) are major challenges faced by the semiconductor industry as outlined by the roadmap in the latest International Technology Roadmap for Semiconductors (ITRS). Advanced tools used [...]

Synthesis and Characterization of Magnetite Powders

Silverman B.M., Parasher S., Milner B., Zhou B., Headwaters Technology Innovation Group, US

Low-cost magnetic powders have been synthesized by Headwaters Technology Innovation Group. These powders exhibit a strong magnetic susceptibility mainly due to magnetite formation. The potential applications for this product range from cancer treatment, ferrofluids, to [...]

Study on non-Freon air cooling system using water refrigerant

Sugawara A., Nakamikawa S., Kageyama M., Yamazaki S., Abe N., Itou T., Tsurumaki A., Kawasaki K., Niigata University, JP

This paper aims for construction of a small, clean air cooling system using a water refrigerant and examines it experimentally. We offer a basic report for realization of the non-Freon air-cooling system using only water [...]

Resist Mask Designs for Quantum Dot Transistor Using E-Beam Nanolithography

Hashim U., Sutikno S., Jamal Z.A.Z., Northern Malaysia University College of Engineering (KUKUM), MY

Quantum dot single electron transistor (QD SET) can be fabricated using e-beam nanolithography (EBL) and then continued by combination process of pattern dependent oxidation (PADOX) and high density plasma etching. EBL was used to pattern [...]

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) [...]

Development of Functionally Graded SiC-Based

Gerdes T., Willert-Porada M., University of Bayreuth, DE

Hot gas filtration using ceramic filters for diesel engine exhaust gas cleaning has gained considerable attention and growth over the last 15 years. In this contribution the development of a SiC-carbide based filter that combines [...]

DIRECT: An Efficient Optimization Scheme for Mask Generation Using Inverse Lithography

Xiong W., Tsai M-C, Zhang J., Yu Z., Tsinghua University, CN

Resolution Enhancement Technologies (RETs) are widely used to cope with the severe optical effects that are manifests in sub-wavelength lithography. Inverse Lithography Technique (ILT) has recently been proposed [1-3] as an effective RET for sub [...]

Magnetic Properties of Multi- and Sigle-Domain Particles of CuxNi1-xFe2O4 Ferrites

Msomi J.Z., Moyo T., University of the Free State, ZA

The crossover effect from multi- to single-domain particles on the magnetic properties of CuxNi1-xFe2O4 oxides due to grain size reduction to nanometre scale is investigated. The properties of the bulk and nanosized oxide have been [...]
