Mikrowellenplasma-Simulation, Abscheidung und Charakterisierung von polykristallinen, dotierten und undotierten Diamantschichten
… Schichten herstellen zu können, wurde ein neuer Mikrowellenplasma-Reaktor mit ellipsoidförmigem Reflektor (Ellipsoidreaktor ERIX) aufgebaut. Als Dotierquelle für Bor wird flüssiges Trimethylborat (TMB) verwendet. Mit Hilfe einer Gasmischanlage können die Bor-Konzentrationen über fünf …

Numerische Untersuchung von N 2 -O 2 -Plasma-Freistrahlen als plasmatechnologische Methode zur NO x -Reduktion in synthetischen Abgasen
The attempt to use microwave induced N2-O2 plasmas to reduce NOx emissions of direct injecting gasoline and Diesel engines reaching the limits of the EURO 4 exhaust gas standards is of special interest. This work makes the attempt to explore the fundamental plasmachemical reaction paths of NOx …

Untersuchungen zur Modifizierung von Folien und Nadelfilzen aus Polyethylenterephthalat mit Fluorcarbonplasmen
Needle felts from PET are commonly used for textile filters because of their low costs and good mechanic properties. The filter surface is provided with fluorocarbon compounds by a wet chemical process as best available technology for achieving a low surface energy and an easy dedustion. Although a …

Behandlung von PP- und PET-Substraten im Argon- und Methan, Argon-Plasma
PP and PET are very cheap materials with a growing market. Due to the improvement of surface properties of these polymers microwave induced plasma is an favourably method. In particular reduced damages of the polymer with the low temperature in plasma processes are expected. The aim of the work was …

Funktionalisierung von Polydimethylsiloxan-Oberflächen zur Steuerung molekularer Zell-Substrat Wechselwirkungen
Aim of this work is the formation of biologically functional PDMS surfaces which are able to control adhesion and proliferation of cells like fibroblasts and keratinocytes. This purpose requires biologically inert hydrogel layers on PDMS that prevent unspecific protein adsorption and - as a …
