Introduction Production of parts using polymer-based composite materials requires physicochemical transformation of the matrix components.
To reduce the production time, it is necessary to raise the temperature of the materials to accelerate the physicochemical transformation.
However, polymeric materials are usually low in thermal conductivity and high in thermal degradability.

Real-time analyses of metal contaminations in the ppb-range Albert Hutterer 1, a, Michael Bauhuber1, Helmut Hummel1, Alfred Lechner1 1University of Applied Sciences Regensburg, Seybothstraße 2 93053 Regensburg, Germany aalbert.hutterer@hs-regensburg.de Keywords: real-time, online measurement, complexing agent, metal ions, total internal reflection, analyses, liquid-core waveguide, light guidance, absorption, Introduction In high-tech processing even smallest concentrations of metal ions in process media are of the utmost significance because they cause expensive production failures.
The Centers of Excellence Nanochem and Sensorics at the University of Applied Sciences Regensburg (owner of patent PCT/EP2010/064833) and their industrial partner Micro-Epsilon GmbH are developing a new miniaturized measurement device which allows cost-effective real-time analysis of fluidic media for the first time.
The simulated channel design is etched isotropically in silicon with a wet-chemical spin-etching method, optimized at the University of Applied Sciences Regensburg.
This acidic etching process, in contrast to alkaline processes, results in isotropic channels in crystalline materials like silicon [4-6].
