Speaker: Kostya (Ken) OstrikovProfessor

 

Kostya (Ken) Ostrikov is Professor of Queensland University of Technology and Science Leader of Office of Chief Executive of CSIRO. His achievements include Pawsey (2008) medal of Australian Academy of Sciences, Walter Boas (2010) medal of Australian Institute of Physics, Building Future Award (2012), NSW Science and Engineering Award (2014), election to the Academy of Europe (2015), >10 prestigious fellowships/professorships in 6 countries, several patents, 3 monographs, and >500 journal papers. His research on nanoscale control of energy and matter helps solve the grand challenge of directing energy and matter at nanoscales, to develop renewable energy and energy-efficient technologies for a sustainable future.

 

Abstract:

This presentation poses and critically examines two fundamental questions, the cornerstones of plasma nanoscience: 1) what happens when low-temperature plasmas face a solid object of nanoscale dimensionsand 2) is it possible to reduce the plasma size to the nanoscales, similar to other (solid, liquid, and gas) states of matter? And what unique and interesting physical and chemical effects one could produce through these localized interactions at plasma-solid interfaces? Interestingly, these interactions at the plasma interface lead to the many synergistic effects which in turn appear useful in the applications of low-temperature plasmas for nanoscale synthesis and processing, catalysis, development of sustainable green-chemistry-based industrial processes, and in the attempt to harness unique and exotic effects when attempting to reduce the size of plasmas down to nanometer domain. Some of the examples of these synergistic effects are related to plasma-nano-catalysis, sustainable, green-chemistry based nanotechnology, and nano-plasmas generated by intense radiation. The most relevant plasma interfacial phenomena will be discussed, e.g., synergistic effects of the plasmas and nanoscale catalysts that may potentially lead to value-added products. The relevant physical limitations in the approach to generate nanoplasmas (can the plasma go nano?) will be introduced to help evaluate some of the possibilities to generate such plasmas and discuss the relevant transient and highly non-equilibrium phenomena. I will also discuss and interpret related effects owing to nanoscale plasma-surface interactions, as well as size-dependent and other intriguing nanostructure properties.
