This presentation reviews and highlights the key aspects of progress achieved in plasma
nanoscience research over the last dozen years. The advances made and the knowledge base
created is critically examined through the prism of the fundamental framework structured
along the key fundamental questions: (1) what happens when low-temperature plasmas face a
solid object of nanoscale dimensions [1] and (2) is it possible to reduce the plasma size to the
nanoscales, similar to other (solid, liquid, and gas) states of matter [2]?
These fundamental questions are at the foundations of plasma nanoscience. The
answers lead to better understanding of many unique and interesting physical and chemical
effects that could be generated through such nanoscale localizations of multi-phase
interactions at plasma-solid interfaces under extreme non-equilibrium conditions.
Many synergistic (1 + 1 >2) effects appear through these interactions at the plasma
interface. These effects enable several advanced applications of low-temperature plasmas in
micro- and nanofabrication, nanoscale materials synthesis and processing, industrial
catalysis, new sustainable industrial processes based on green-chemistry approaches. Many
exotic effects appear when plasma size is reduced into nanometre domain. The examples are:
plasma-nano catalysis [3], sustainable nanotechnology [4], nanoscale plasma-surface
interactions [5], and nano-plasmas generated by intense radiation [2].
The presentation will conclude with some examples of using plasma, thermal, ionic
and other processes to control macroscopic properties of materials by precise manipulations
of atomic bonds, atoms and defects at nanoscales and the opportunities for industrial
applications and entrepreneurship [6], and the challenges and cross-disciplinary platforms
such as plasma-materials informatics on the way materialize these ambitious goals.
