Brief
annotation and scientific rationale:
The
aim of the project is to accumulate a database for a better
understanding of the fundamental laws of high-intensity ionization
in model and structural materials. Knowledge of fundamental
mechanisms is of considerable importance for nuclear power
engineering, nanotechnology applications and for testing target
materials for nuclear physics experiments. As an innovative
approach, it is proposed to study the effects of dense ionization
on a previously created defect structure, which was formed by
exposure to “conventional” radiation (hundreds of keV
and units of MeV, ion irradiation), which is the most reliable way
to simulate damage produced by fission products.
The
main approach to achieving the goals of the project will be the
use of modern structural analysis techniques –
high-resolution transmission electron microscopy in combination
with molecular dynamics methods for modeling track formation
processes. Structural changes will be also investigated using
scanning electron microscopy, X-ray diffraction, confocal Raman
and luminescence microscopy, and real-time optical spectroscopy
under ion irradiation. The radiation resistance of promising
reactor materials and target materials for nuclear physics
experiments will be investigated by micro- and nanomechanical
testing methods.
Expected
results upon completion of the project:
Advanced
understanding
of the fundamentals of high-density ionization in solids, based
on the studied dependencies of the kinetics of structural changes
in the tracks of swift heavy ions in the near-surface areas of
nanostructured dielectrics – nanoparticles, interfacial
layers, layered structures.
Results
of modeling by molecular dynamics methods of lattice relaxation
processes and the formation of regions with a modified structure
in the near-surface and interphase regions of composite materials
exposed to energetic ions – nanoclusters in matrices,
layered materials.
Data
on the combined effect of dense ionization and helium on the
transport properties of fission fragments in protective layers
and inert matrices.
Accumulation
of a database on the parameters of ion tracks in conventional and
nanostructured ceramics promising for nuclear physics
applications
Data
on the long-term stability of target materials during prolonged
irradiation with intense heavy ion beams.
Expected
results of the project in the current year:
Investigation
of the microstructure of the interface layers AlN/Al2O3,
CeO2/ZrO2: Y, Si/Al2O3 irradiated with high-energy heavy ions by
high-resolution transmission electron microscopy.
Measurement
by TEM methods of the parameters of helium porosity in nickel-
and titanium-based alloys uniformly
ion-doped with helium
and annealed.
Micromechanical

high-energy xenon ions.

Brief
annotation and scientific rationale:
The
project’s goal is to develop nanocomposite and functional
track-etched membranes (TMs) for their applications in
nanotechnology, biomedicine, sensor technologies, and novel
membrane separation processes.
TMs
are an example of the industrial application of ion-track
technology. They have a number of significant advantages over
conventional membranes due to their precisely determined
structure. Their pore size, shape, and density can be varied in a
controllable manner so that a membrane with the required transport
and retention characteristics can be produced. The modern trends
in biology, medicine, environmental research, green energy
harvesting, and other areas formulate the demands for membranes
with specific novel functionalities. These functionalities can be
provided by tuning (setting) the geometry, morphology, and
chemical properties of TMs. The present project will focus on the
development of various functional
track-etched
membranes using the following approaches:
Tuning
the pore architecture.
Composite
structures.
Hybrid
structures.
Targeted
chemical and biochemical modification.
Selection
of bulk material.
Special
attention will be focused on
biomedical
applications of
track-etched membranes. The
main result of the project will be the creation of scientific and
technical foundations for the development of new membranes with
specific functions.
The applicability of the developed
membranes in practically important membrane separation processes,
biomedical procedures and analytical tasks will be investigated.
Expected
results upon completion of the project:
Functionalized
TMs obtained from ion-irradiated polymer films using soft
photolysis and liquid extraction of degradation products from
tracks for the electrodialysis
and electro-baromembrane process:
– determination
of ion-selective properties of the membranes;
– investigation
of the possibility of mono- and multivalent-ion separation on
nanoporous TMs using the electrodialysis
and electro-baromembrane process.
Experimental
verification
of results on
the possibility of manufacturing nanocomposite, functionalized,
and hybrid TMs:
– TMs with asymmetric and modified
nanopores for the separation of racemic mixtures;
–
microfiltration TMs with immobilized proteins for the detection
of free RNA and DNA and their use in biosensors;
–
functionalized nanoporous membranes made of polyvinylidene
fluoride (PVDF) for selective preconcentration of toxic
metals and their quantitative determination;
– TMs
functionalized with silver nanoparticles and bioactive substances
for the creation of bactericidal and viricidal filtration
materials;
– modified TMs with improved cell adhesion
for cell culture systems;
affinity ultra- and
microfiltration TMs for exosome separation;
–
nanocomposite TMs with immobilized silver and gold nanoconjugates
and aptamers for the diagnosis of viral diseases using SERS and
fluorescence spectroscopy;
– hybrid TMs with surface
polymer nanofiber structures and modified selective complex
compounds, ligands and metal-organic frameworks for selective
removal of toxic metals from water.
Data
on ion-selective, electrokinetic, and osmotic properties of
modified nanopores, including asymmetric nanopores, depending on
their geometry and functional groups on the surface.
Expected
results of the project in the current year:
Investigation
of the patterns of track formation in polyvinylidene fluoride
under heavy-ion irradiation and production of nanoporous PVDF
TMs. Development of methods for modification of nanoporous PVDF
TMs by functional monomers using postradiation graft
polymerization

with a core/shell structure consisting of silver and gold for
further use in the analysis of viruses employing aptamers

hydrophobic coatings obtained by electron-beam dispersion of
polymers.
Study

conjugates of curcumin and quercetin, as well as the evaluation
of their biological effectiveness against RNA and DNA-containing
viruses.
Development
