Title: Does Plasma Matter?

Date/Time:  Mar. 14 Wednesday @ 10:40 (Coffee/Tea @ 10:20 in SUNUM Hall)

Place:  SUNUM building, room G111


Plasma called fourth state of matter has special characteristics and applications than the other matters.  While plasma occupies more than 99 % of space and most abundant matter in the universe, the use of plasmas in technology and industry is rather limited.  Plasma is one of the state of the art technologies important for high tech industry, surface modifications, thin film, nanomaterial and nanocomposite manufacturing, space physics, and fusion energy.  For example, plasma extends the properties of nanoparticles, nanostructures and nanocomposites beyond those obtained by classical technologies. Plasma complexity can modify the surface properties of various materials in order to form nanomaterials, nanoparticles and nanostructures by etching, depositing, crosslinking, aggregating or functionalizing the surface for many purposes; damaging or unwanted processing can also occur. Although plasma is used in surface modification for nanomaterial manufacturing, its physics and chemistry are not understood well. Understanding the plasma physics and technology from space physics, fusion down to nanoscale is crucial in order to control and design many materials and equipments.  Recently plasma techniques have gained increasing importance for bio-applications such as microarrays, modified substrates for tissue engineering, biocompatible materials, etc.

This talk intends to give an overview of plasma characteristics, plasma diagnostic techniques and direct and indirect plasma applications.
