NanoZeolites – porous nanomaterials for cleantech, encapsulation and triggered release applications

Daniell W., Sauer J., Kohl A., NanoScape AG, DE

Recent advances in hydrothermal synthesis techniques and procedures to modify the surfaces of the particles have led to the development of a new class of material – the NanoZeolites. The availability of porous, nanocrystalline materials [...]

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 [...]

NanoEnergy- Technological and economical impact of nanotechnology on the energy sector

Luther W., VDI Technologiezentrum GmbH, DE

In respect of narrowing fossil energy resources and potential side effects of climate warming carbon dioxide emissions it becomes obvious that for a sustained longterm economical prosperity a fundamental renewal of the energy sector will [...]

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 [...]

Improved layout dependent modeling of the base resistance in advanced HBTs

Lehmann S., Schroter M., University of Technology Dresden, DE

Existing equations for describing the layout dependent base resistance are improved and extended for heterojunction bipolar transistors (HBTs) in advanced process technologies. The new equations have been developed using quasi-3D device simulation and have been [...]
