Development of a Scalelable Interconnection Technology for Nano Packaging

Becker K.-F., Löher T., Pahl B., Wittler O., Jordan R., Bauer J., Aschenbrenner R., Reichl H., Fraunhofer IZM, DE

Microelectronics miniaturization is following Moore’s law since the mid sixties and over the years it has always been possible to follow it without meeting fundamental technological limits. This might be in question for future applications, [...]

Coating of Glass Surfaces with Nanoparticles of different Materials Synthesized in Microemulsions

López-Trosell A., Schomäcker R., TU Berlin, DE

In this paper a developed methodology is presented to coat glass substrates with nanoparticles of different materials. Particles of palladium, zirconium oxide, yttrium iron garned and perovskite Ca0.5Sr0.5MnO3 were synthesized in microemulsions. The microemulsions form [...]

Nanomechanical Properties of Silica Coated Multiwall Carbon Nanotubes – Poly(methyl methacrylate) Composites

Olek M., Kempa K., Jurga S., Giersig M., Caesar - Research Center, DE

Nanomechanical properties of polymer composites, reinforced with silica coated multiwall carbon nanotubes (MWNT), have been studied using the nanoindentation technique. The nanohardness and the Young’s modulus have been found to increase strongly with the increasing [...]

Synthesis and Characterization of Perovskite Ca0.5Sr0.5MnO3 Nanoparticles in w/o-Microemulsions

López-Trosell A., Schomäcker R., TU Berlin, DE

In the present work, w/o-microemulsions were employed to produce nanoparticles of perovskite Ca0.5 Sr0.5 MnO3. The reaction inside the microemulsion droplets was achieved by addition of sodium hydroxide as co-precipitation agent. Afterward the precursor of [...]

Simulation Toolkit for Micro-Fluidic Pumps using Lumped Models

Litterst C., Streule W., Zengerle R., Koltay P., IMTEK, University of Freiburg, DE

Simulation of micro pumps is complicated by the interaction of various physical domains. The fluid structure interaction (FSI) essentially determines the dynamics of micro pumps and therefore has to be taken into account. Mesh based [...]

Compact Model of a Laminar Micro Mixer

Cupelli C., Koltay P., Zengerle R., Santer M., University of Freiburg, DE

In this paper we discuss a novel approach towards a system-level description for microreactors. In particular, a compact model for laminar micromixers for fluids with different viscosities is presented. We show how the well known [...]

Flat Fluidics: Programmable On-Chip Networks for Biological and Chemical Applications

Wixforth A., University of Augsburg and Advalytix AG, DE

We present a novel approach towards the needs of a versatile microfluidic chip-based microfluidic system with unique properties and functionality. Like for microarrays and in contrast to many existing microfluidic technologies, the fluid handling is [...]

Design Paradigms and Methodologies for Microfluidics

Hardt S., Darmstadt University of Technology, DE

This paper reviews and compares different strategies for designing and building up microfluidic systems, with a special emphasis on the system aspect as opposed to single components capable of performing only special operations. An overwhelming [...]

A Novel Class of Sensors for System Integrative Concepts in Biotechnological Applications

Schober A., Kittler G., Kittler M., Buchheim C., Majdeddin A., Cimalla V., Fischer M., Yanev V., Himmerlich M., Krischok S., Schaefer J.A., Romanus H., Sändig T., Burgold J., Weise F., Wurmus H., Drüe K.H., Hintz M., Thust H., Gebinoga M., Kittler G., Kittler M., Spitznas A., Gottwald E., Weibezahn K-F., Wegener D., Schwienhorst A., Ambacher O., Technical University of Ilmenau, DE

The application of an system integrative approach based on hetereostructure sensors (group III nitrides) for the examination of differnt biological systems is shown and discussed.

TMAZ Nanoparticles as Potential Drugs Influencing the Cellular Signal Transduction Pathways

Ivkovic S., Baranek T., Bendzko P., Schulz J., Klinomed Institut für Angewandte Nanotechnologie und Nanomedizin GmbH, DE

Currently, various antioxidants are under clinical investigation as an adjunct to standard and experimental cancer therapies. Anti-cancer activity of antioxidants may not only be attributed to their radical scavenger properties, but also to direct modulation [...]
