1.
Rapid hydrophilization of model polyurethane/urea (PURPEG) polymer scaffolds using oxygen plasma treatment

This extensiove paper (18 pages) was published in journal "Polymers" - a highly reputable journal in the field of tailoring surface properties of polymers. The paper is a result of collaboration with biochemists from Shantou University (a private establishment in one of the Chinese special economic zones). Innovative material of great potential for biodegradible scaffolds in tissue engineering was nanostructured and functionalized by plasma treatment leading to excellent biocompatibility.

The influence of growth defects in sputter-deposited TiAlN hard coatings on their tribological behavior

This journal is perhaps the most reputable in the field of thin films so our research group publishes scientific results regularly. The growth kinetics was explained to details stressing the influence of defects upon sputter-deposition of such hard coatings.

Erosion of a-C:H in the afterglow of ammonia plasma

This paper is a result of fruitful collaboration with foreign fusion-oriented research groups. We report an innovative method from removal of hydrogenated carbon deposits from inner surfaces of fusion plasma reactors. We take advantage of high chemical reactivity of NHx radicals which are capable of removal the deposits even in remote areas of thermonuclear reactors.

Reduction of a thin chromium oxide film on Inconel surface upontreatment with hydrogen plasma

Corrosion represent a major technological issue so various alloys have been developed to suppress it, but so far no appropriate material has been invented. Inconel is one of the best materials but still suppers from chromia film that forms in hash conditions. We managed to remove this film at reasonable temperature usng highly reactive hydrogen plasma. Research was a part of an EU project.

Degradation of albumin on plasma-treated polystyrene by soft X-ray exposure

One of the most advanced beamlines at Soliei synchrotron was used to study the conformation of blood proteins on the surface of polystyrene which had been previously treated by gaseous plasma to obtain desired surface finish. Apart from interesting adsorption kinetics we also observed degradation due to irradiation.
