"MULTISCALE SCIENCE FOR TUNING INTERFACES AT NANOSCALE"

Predrag S. Krstić

University of Tennessee, Knoxville TN 37996-6173, USA

Abstract:

       Plasma-Material Interface (PMI) mixes materials of the two worlds,
creating a dynamical surface which is one of the most challenging areas of
multidisciplinary science, with many fundamental processes and synergies.
The traditional trial-and-error approach to developing first-wall materials
and component solutions for current and future fusion reactors is becoming
prohibitively costly because of the increasing device size, curved toroidal
geometry, access restrictions, and complex programmatic priorities. The
experimentally validated atomistic theory and computation for studying
dynamics of  creation and evolution of the PMI under irradiation by heavy
particles (atoms, molecules) at carbon, lithiated carbon and tungsten, as
well as the emerging elastic and inelastic processes, in particular
retention and sputtering chemistry, will be shown. 

            The National Institute of Health research initiatives over the
past ten years resulted in the reduction of the human DNA sequencing cost by
more than 100,000 times, reflecting the highest rate of progress in history
of science. This research still requires development of fast, label-free and
cheaper technologies, which can be massively produced and used. Particularly
interesting is the prospect of the so-called physics-based third-generation
methods, since these are intrinsically fast and can operate on a single DNA
or protein polymer. Multiscale theory and computation, with predictive
powers for localization, control, detection and recognition of biomolecules
in nanofluidic environment will be presented. 

 

Predrag Krstic

is senior research scientist of Joint institute of Computational Sciences
and adjunct professor of physics at Department of Physics and Astronomy of
University of Tennessee, till recently senior staff scientists at Oak Ridge
National Laboratory, founder and owner of TheoretiK Consulting, contractor
of NIH, ORNL,ArizonaStateUniversity,YaleUniversity.     

  Dr. Krstić completed his PhD degree at City College of C.U.N.Y on the
multiphoton theory, after obtaining his BSC and MSC in technical physics
from University of Belgrade. His research includes a wide range of fields,
from physical methods for DNA sequencing and biomolecule sensing,
plasma-facing surface physics, to molecular collision physics, quantum and
classical molecular dynamics, multiphoton physics and chemistry. This work
is published in more than 200 journal papers, as well as
in book chapters and patents. He has been PI/PD and Co-PI in a series of
grants with DOE, NIH, NSF, and IAEA, consultant of International Atomic
Energy Agency,
Fellow of the American Physical Society.
