Plasma-surface interactions

Plasma-surface interactions of hydrogenated carbon

We present a review of our study of interactions of plasma particles (atoms, molecules) with hydrogenated amorphous carbon surfaces typical of plasma-facing divertor tiles and deposited layers in magnetic-fusion reactors. Our computer simulations of these processes are based on classical molecular dynamics simulations, using the best currently available multibody bond-order hydrocarbon potentia...

Fundamental Ion–surface Interactions in Plasma Thrusters

Ion thrusters offer the potential to enable many future interplanetary robotic missions presently under consideration by NASA. To realize the benefits offered by these low thrust devices, the sputtering mechanisms that are responsible for the degradation of thruster components over time must be well understood. Predictions of thruster life depend directly on the material removal rates from thru...

Plasma-surface Interactions of Model Polymers for Advanced Photoresist Systems

Title of Document: PLASMA-SURFACE INTERACTIONS OF MODEL POLYMERS FOR ADVANCED PHOTORESIST SYSTEMS Sebastian Ulrich Engelmann, Doctor of Philosophy, 2008 Directed By: Professor Gottlieb S. Oehrlein, Department of Material Science and Engineering Plasma processing of advanced photoresist (PR) materials is a critical step in nano-manufacturing. We have studied the interactions of PRs and polymers ...

Characterization of drug-plasma protein interactions using surface plasmon resonance

Binding to plasma proteins is a key parameter in evaluating candidate compounds during the lead optimization and early ADME phases of the drug development process. Biacore’s surface plasmon resonance (SPR) technology is ideally suited for the analysis of multiple aspects of drug-plasma protein interactions. BiacoreS51 was used to analyze a panel of low molecular weight drug compounds for bindin...
