Liquid transport detection using single FET devices

Truman P., Uhlmann P., Stamm M., Institute of Polymer Research, DE

Observation and monitoring liquid transport and transport in liquids is a major task for lab on a chip applications and research. We use novel thin film FET devices based on silicon-on-insulator (SOI) substrates as planar [...]

Methods of energizing micro flows by acoustic and electric fields

Schönfeld F., Dadic D., Hardt S., Püschl R., Schmitz F., Institut für Mikrotechnik Mainz –(IMM), DE

We present two different concepts for energizing (e.g. mixing, pumping) of micro flows, which rely on the coupling of acoustic and electromagnetic energy into a liquid. Both concepts are analyzed using computational fluid dynamics (CFD) [...]

Separation dynamics of binary liquid mixtures – Theory & Experiment

Truman P., Varnik F., Uhlmann P., Stamm M., Raabe D., Institute of Polymer Research, DE

We study how chemically patterned surfaces can be applied for the separation of two incompatible liquids and introduce a novel simplified separation scheme utilizing surfaces with an abrupt change of surface energy. Firstly we analyse [...]

A Method for Semi-Automated Modeling of Analog-Mixed Signal Systems in Automotive Applications based on Transient Simulation Data

Mielenz H., Doelling R., Rosenstiel W., Robert Bosch Group, DE

Functional verification by simulation is an important step during the development of present microelectronic solutions for automotive applications. Its relevance is based on the capability to compare the behavior of a developed circuit with its [...]

Optimization of Masks for High Aspect Ration UV-Lithographic Patterning

Triltsch U., Büttgenbach S., Technische Universität Braunschweig, DE

The increasing complexity of micro actuators and micro sensors (e.g. electroplated micro coils, flux guidances, insulation and planarization layers) make new fabrication technologies and materials inevitable. For such purposes thick-film photo resists like SU-8 or [...]

Piezoresistive effect in DLC Films and Silicon

Tibrewala A., Phataralaoha A., Peiner E., Bandorf R., Büttgenbach S., TU Braunschweig, DE

In this work piezoresistive effect in Diamond-like carbon (DLC) films and p-diffused strain gauges is compared for the first time. DLC films are already well known in optical coatings. Here it is integrated with silicon [...]

Nano-Catalysts and Colloidal Suspensions of Carbo-Iron for Environmental Application

Mackenzie K., Hildebrand H., Kopinke F.-D., Helmholtz Centre for Environmental Research - UFZ, DE

The presentation contains two innovative applications of nano-sized materials for environmental application: 1) Pd catalysts for wastewater treatment. The new ferromagnetic nano-sized Pd catalysts have proved effective for selective dechlorination of industrial wastewater. Extraction by [...]

Nanobiopore: A Novel Nano-Porous Electrode System to Enhance Biosensor Sensitivity

Müller U., Nisch W., Neugebauer S., Schuhmann W., Linke S., Kaczor M., Lohmüller T., Spatz J., Motz M., Sorsa J., Hecke S., Hartwich G., Stelzle M., NMI Natural and Medical Sciences Institute, DE

The primary objective of this research is to create electrode systems for use as electrochemical transducers with enhanced sensitivity in order to enable detection of low concentration diagnostic targets not accessible to date. NanoBioPore sensors [...]

Dispersing Nanoparticles – The Key to Application

Pilotek S., Tabellion F., Schär S., Steingröver K., Buhler PARTEC GmbH, DE

Inorganic nanoparticles are used in many different branches: e.g. display technology, consumer goods, coatings, plastics, cosmetics, and paper industry use nanoparticles as major components or functional additives. In most applications, the particles are needed in [...]

Smart Silver Nanoparticles from Nanoreactors made by Invertible Polyesters

Voronov A., Kohut A., Peukert W., Friedrich-Alexander University Erlangen-Nuremberg, DE

A simple way to prepare uniform amphiphilic silver nanoparticles in concentrated solutions of an invertible polyester is developed. The mobility of polymer fragments increases by dissolving of the polyester in benzene. Experimental data show that [...]
