Permittivity of BaTiO3 polymer composite with differing particle size distribution

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe GmbH, DE

In previous works the authors presented the possibility to raise the permittivity of polyester-reactive-resin composite materials by using thermal treatment steps to optimize the crystal structure of a nano-powder before incorporating it into the composite. [...]

Lipid Dip-Pen Nanolithography for Functional Biomimetic Membrane Systems

Lenhert S., Forschungszentrum Karlsruhe GmbH, DE

Dip Pen Nanolithography (DPN) is uniquely well suited for the integration of multiple materials (or inks) with both high resolution and high throughput. Phospholipid-based inks are particularly well suited for this purpose for several reasons. [...]

Simulation of Electrically-Excited Flows in Microchannels for Mixing Application

Meisel I., Ehrhard P., Forschungszentrum Karlsruhe GmbH, DE

In the present paper we propose a method for improved mixing in microchannels. The basic idea is to excite a secondary vortex flow around an obstacle within the micromixer by applying an external oscillatory electrical [...]

Simulation of a Micro Optical Distance Sensor Realized by the LIGA Process

Guth H., Hellmann A., Sieber I., Eggert H., Mohr J., Nakajima H., Tanimot K., Usami T., Forschungszentrum Karlsruhe GmbH, DE

The aim of the presented work is to simulate and validate an ultra miniaturized optical distance sensor, which works by means of triangulation. The sensor is dedicated for a detection range of 1 to 6mm [...]
