The current generation of tissue engineered additive manufactured scaffolds for cartilage repair shows high potential for growing adult cartilage tissue. This study proposes two surface modification strategies based on non-thermal plasma technology for the modification of poly(ethylene oxide terephthalate/poly(butylene terephthalate) additive manuf...
Multiple vapor inlet systems have been developed to enhance the homogeneity of deposited polyacrylic acid films via medium and atmospheric pressure plasma technology. Different inlet systems were experimentally tested and optical reflectance spectrometry (OPS) was used to measure the differences in thickness of the films along the exposed surface. ...
In this paper, water vapor up to 41% is added to an argon dielectric barrier discharge at medium pressure to profoundly investigate the effect of water vapor addition on the surface modification of polyethylene (PE). Contact angle measurements show that the wettability of PE significantly increases after a pure argon plasma treatment. However, the ...

In this work, medium pressure plasma treatment of polylactic acid (PLA) is investigated. PLA is a biocompatible aliphatic polymer, which can be used for bone fixation devices and tissue engineering scaffolds. Due to inadequate surface properties, cell adhesion and proliferation are far less than optimal and a surface modification is required for mo...
By using a DBD plasma, several layers of PET non-woven are treated to study the penetration of plasma into the textile material. The influence of the pore size and of the power on the penetration effect is investigated. By using a horizontal wicking experiment, the plasma effect is quantified.
The increasing emission of CO_2, due to the growing power consumption, requires more and more efforts to replace fossile fuels by sophisticated no-emission systems in power generation. Using photovoltaics is one possible option. Producing electricity by solar energy, photovoltaics may contribute to a significant reduction of CO_2 emissions. The bas...
