Microwave-assisted superparamagnetic FePt synthesis for MRI application

Tsai J.L., Tsai M.J., Tsai T.Y., Tsai J.L., Tsai M.J., Tsai T.Y., Tsai J.L., Tsai M.J., Tsai T.Y., Lai P.S., National Chung Hsing University, TW

uperparamagnetic iron oxide (SPIO) nanoparticles have demonstrated their practicability as MRI T2-shortening agents for non-invasive cell labeling, drug delivery or tumor detections in clinical practice. Recently, superparamagnetic chemically disordered face-centered cubic (fcc) FePt nanoparticles has [...]

Synthesis of highly-doped silicon and germanium nanoparticles in a low-pressure plasma-reactor for thermoelectric and solar applications

Grimm H., Petermann N., Gupta A., Wiggers H., University of Duisburg-Essen, DE

Microwave-plasma induced thermal decomposition of gaseous precursors like germane (GeH4) and silane (SiH4) is used to synthesize semiconductor nanoparticles for thermoelectric and thermal applications. P and n-doping can be achieved by mixing silane and germane [...]

Au, Ag and Au-Ag nanoparticles: microwave-assisted synthesis in water and applications in ceramic and catalysis

Blosi M., Albonetti S., Gatti F., Dondi M., Migliori A., Ortolani L., Morandi V., Baldi G., Istec-CNR, IT

The research was focused on the synthesis of Au, Ag and Au-Ag core-shell sols, prepared by a patented microwave-assisted green synthesis. The method provides colloidal mono and bimetallic nanoparticles throughout the reduction of precursor’s salts [...]

Domestic hydrogen production by an integrated biomass gasification/sponge iron process

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

The share of hydrogen in the energy market is increasing with the implementation of fuel cell systems and the growing demand for zero-emission fuels. One major challenge is a distribution system for hydrogen. This drawback [...]

Bio Mass for CO2 Neutral Steel Production

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

The paper presents a process to strongly increase the efficiency of bio mass as energy source in steel production by direct use of wood chips instead of charcoal combined with a new microwave based heating [...]

Micrwave based microfluidic sensor

Tanbakuchi H., Bynum M., Brennen R., Whitener M., Agilent Technologies, US

SPR ( surface Plasmon Resonance) is an non destructive sensor capable of measuring the changes in refractive index above the gold surface (~300 nm) .The advantage of the SPR is in its capability of looking [...]

Development of a Mobile Asbestos Decontamination Process

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

Within the European project “New Safe and Cost Effective Techniques Against Asbestos Risks” different methods for decontamination of asbestos in asbestos containing wastes, abbreviated as ACW from building industry were investigated. A mobile asbestos decontamination [...]
