Mechanochemical Activation and Synthesis – An Ecological Friendly Process in the Production of Materials for Photocatalytic Air and Water Purification
Program: Medziakademická dohoda (MAD)
Project leader: RNDr. Fabián Martin PhD.
Annotation: Doping of simple oxides (e.g. TiO2, ZnO, Fe2O3 etc.) by nitrogen results in formation of oxygen defects and shift of optical wavelength absorption maximum from UV to visible region. This fact has a great influence on preparation nanocrystalline photocatalysts working not only with UV but also with visible light. Due to the project we have prepared N doped TiO2 and ZnO. The change of their colour indicates the shift of absorption maximum from UV to visible region. This behaviour was further confirmed by DRS spectroscopy. Microstructural changes were evaluated by XRD and XPS analyses. At the present the as-prepared materials are tested for photocatalytic activity on azodyes (liquid phase) and ethylene (gas phase).

The presently known commercial TiO2 photocatalysts, based on anatase/rutile synergism, will be improved by finding an appropriate substitute of the either of anatase or rutile component with other narrow-band semiconductors. Obtaining and applying the visible-light-active photocatalysts to water and air treatment and testing them in suspension reactors (water purification) and in flat-plate gas-phase continuous flow photocatalytic reactor (air purification) will be the aim of our study. The kinetics of the photocatalytic reactions will be evaluated on the basis of Langmuir-Hinshelwood model both under continuous flow conditions (plug-flow reactor) and under flow-circulation conditions using a gas circulation pump (ideal mixing reactor) to enter the kinetic region. The effect of the thickness of the photocatalytic coating with respect to operation in the diffusion or in the kinetic region will be estimated. Optimal experimental conditions for maximal conversion degree will be selected in view of achieving steady state operation and optimal reactor configuration removing the dead zones.

Development of a system for continuous monitoring of pollution impact on the high-voltage insulation
Program: APVV
Project leader: RNDr. Fabián Martin PhD.
Annotation: The dynamics of the environmental pollution is affected by the industrial emissions and the ongoing climatechange. The environmental pollution on electrical insulation is one of the problems faced by distribution utilitiesand electricity transmission system. Moreover, it can be classified as a potential danger for reliable operation ofan electric power system. Seasonal conversions affect the tendency accumulation of contaminants on thesurface of insulators and cause chemical changes which influence their original characteristics. This fact needsto be addressed, as mentioned insulation is an important part in the chain of the transmission and the distributionsystems reliability. Current knowledge points to the fact that, depending on the profile of the insulator, thepollution, the humidity and the temperature of the surface are strongly related to the insulation withstand.External pollution modifies the electrical breakdown strength of isolation. In Slovakia, thousands of insulators areincluded in the electricity transmission and distribution systems. Nevertheless, at present time in Slovakia noinformation is gathered about the current state of pollution in key areas of strategic energy objects. The project isfocused on the development of modern equipment, enabling real-time monitoring of insulator surface conditioneither in autonomous mode or as part of an existing network-based IT infrastructure with a remote dispatchingcontrol system. This proposal of research and development is invoked by the project implemented within the EU

Mechanizmus protinádorového účinku nanočastíc realgáru a synergia s anti-myelónovými liečivami
Mechanism of anti-tumor activity of realgar nanoparticles and its synergism with anti-myeloma agents
Program: VEGA
Project leader: Mgr. Bujňáková Zdenka PhD.
Annotation: Multiple myeloma (MM) is the second most common hematological malignancy of plasma cells, which remains largely incurable despite improved survival after development of novel therapies. Arsenic trioxide (ATO) shows limited response due to long-term toxicity in clinical phase II trials of relapsed and refractory MM patients, whereas arsenic sulfide in the form of realgar nanoparticles (NREA) differs comparing with ATO with profoundly better safety. Furthermore, our preliminary data showed higher anti-MM activity of NREA than ATO. Therefore, the goal of this proposal is to define the molecular mechanism of anti-MM activity of NREA in MM pathogenesis, either alone or in combinations with anti-MM agents, using our established in vitro validation systems and preclinical in vivo models to provide the framework for clinical evaluation of NREA as novel MM therapy.

Study of physico-chemical properties of nanooxides prepared by combined mechanochemical-thermal synthesis
Program: VEGA
Project leader: RNDr. Tóthová Erika PhD.
Annotation: The research will be focused on the preparation of two attractive materials with interesting physico-chemical properties by combined mechanochemical-thermal synthesis. The plan (intent) concerns the multiferroic material LiFeSi2O6 and the well-known semiconductor ZnO. The accent is put on the preparation route, i.e. on the mechanochemical activation and following calcination of the precursors. The unconventional mechanochemical activation increases the internal and surface energy and decreases the coherence (cohesion) of the material at the same time, and this can reduce the temperature of the solid state synthesis. The influence of mechanical activation on the physico-chemical (magnetic and optical) properties of such-prepared material with respect to materials of same composition but prepared by conventional methods will be studied.

The Development of Bioremediation Technology of Metals Removing from Soil and Sediment
Program: VEGA
Project leader: Ing. Danková Zuzana PhD.
Annotation: Heavy metal contamination of soil and sediment is one of the main environmental problems in all world. Heavy metals are generally toxic and non-biodegradable in the soil and sediment matrix. It is important to develop a practical and economical technology for removal of heavy metals from metal-contaminated soils and sediments. Bioremediation primarily uses bacteria to removal and transform heavy metals. The biological method has beenconsidered as an efficient and cost-effective alternative to physicochemical treatment technologies for soil and sediment remediation. Under regulated conditions of bacterial activity, there will be possible to make the biological processes at bioremediation of soil and sediment more effective. The bioleaching mechanism leads tothe decreasing of metals concentration in sediments and these sediments can be applied again into soil. The metals released into leachates by bioleaching will be accumaccumulated by sorption to developed mineral filters which form a closed process.

Project leader: Ing. Ficeriová Jana PhD.
Annotation: The scientific project will be focused on the hydrometallurgical processing (HP) of gold ore from the White Hill deposit and goldsmith\’s wastes in order to obtain Au with utilization of mechanical activation, electrolysis and sorbents. Hydrometallurgy is a group of technologies that are crucial to the economic extraction of Au ores with sub-microscopic Au and also from wastes. Technological processing of Au ores and wastes with an attractive Au content with the requirement for sufficient recovery of the concerned metal is problematic from economic perspective. For this reason, mechanical activation is currently used, which causes changes in the physical and chemical properties, which have significant effect on the intensification of Au extraction in the HP of Au ore and wastes processing. The aim of the HP is to get Au into a solution and then get out it back from the solution. The purpose of Au ore processing and goldsmith\’s wastes using an electrolytic process is to obtain gold in the metallic form.

The particle size dependent magnetic properties of mechanochemically prepared nanomaterials will be studied with the aim to contribute to the understanding of the structure-property relationships in nanocrystalline solids. The range of thermal stability of mechanically induced metastable states and the mechanism of their relaxation into a low-energy state will be determined by studying the response of nanosized oxides to changes in temperature.

Structure-property relationships in nanocrystalline complex oxides prepared by mechanochemical methods
Program: APVV
Project leader: prof. RNDr. Šepelák Vladimír DrSc.
Annotation: Nanocrystalline complex oxides with ferrimagnetic, ferroelectric and/or piezoelectric properties will be prepared via two different mechanochemical routes: mechanosynthesis and mechanical activation of corresponding bulk materials. Quantitative microstructural information on the mechanically induced structural disorder (the non-equilibrium cation distribution, the non-collinear spin arrangement, an alteration of the nearest neighbour configuration deformation of the polyhedron geometry, etc.) in both mechanically activated and mechanosynthesized oxides will be attempted. The magnetic, dielectric and mechanical responses of the as-prepared materials will be studied experimentally and theoretically with the aim to contribute to the understanding of the structure-property relationships in nanoscale oxides. Based on the comparison of the experimental and theoretical results, the properties of the oxide nanoparticles will be additionally tailored by suitably controlling their size. The range of thermal, chemical and structural stability of mechanically induced metastable states and the mechanism of their relaxation into a low-energy state will be determined by studying the response of nanosized oxides to changes in temperature.

The study of the application possibilities of remediation methods in the elimination of environmental risk of acid mine drainage at the old mine loading Smolník
Program: APVV
Project leader: Ing. Luptáková Alena PhD.
Annotation: The matter of the project is the study of possibilities for treatment of acid mine drainage and sediments in the specific conditions of the old mine loading Smolník. The proposal of solution results from monitoring of the locality running for several years, documenting the continued production of strong mineralized and acid mine waters with the high content of heavy metals and sulphates. Whereas there is no condition on self-improving of the situation, one from the possible solution is the treatment of out-flowing acid mine drainage, which enable to eliminate of hazardous elements, or obtaining of useful compounds before they entering into the hydrosphere cycle. The water quality has the marked influence on hazardous elements content in sediments, which can be the potential source of secondary water pollution. Proposed project is focused on development of optimal physical-chemical and biological-chemical methods for pollutant elimination from acid mine drainage and sediments subject to environment.

ENVIBIOKAT – Štúdium environmentálnej biologickej katalýzy v procesoch acidifikácie a mineralizácie banských vôd v biotopoch starých banských záťaží po ťažbe sulfidických rúd
Study of environmental biological catalysis of mine drainage acidification and mineralization in old mine biotope after exploitation of sulphidic ores
Program: VEGA
Project leader: Ing. Luptáková Alena PhD.
Annotation: The project focuses on the study of existence and development of biological "in-situ" processes in the contact zones of hydrosphere and lithosphere in the sulphide ore deposits and their waste deposits. These processes are catalysed to a higher or smaller degree by autochthonous Fe- and S-oxidising microorganisms resulting in the formation of acid mine drainage containing the limit-exceeding heavy metals, which have a strong devastation effect on the surrounding environment. The project objective is to develop a method for the evaluation of environmental risk of these spontaneous natural processes and to study the possibility to use the reversible natural bio-reduction processes for liquidation of unwanted effects of acid mine drainage on the surrounding biotope.

FOCAT – Fotokatalytické čistenie kontaminovaných vôd a vzduchu použitím nanomateriálov
Photocatalytic purification of contamined water and air using nanostructured materials
Program: APVV
Project leader: RNDr. Fabián Martin PhD.
Annotation: The project is directed towards studying the processes of photocatalytic purification of polluted water and air, using nanostructured materials mostly on the basis of oxides. It will be focused on comparison the efficiency of photocatalysts – semiconductors based on oxides, obtained by mechanochemical synthesis with other commercial photocatalysts. The presently known commercial TiO2 photocatalysts, based on anatase/rutile synergism, will be improved by finding an appropriate substitute of the either of anatase or rutile component with other narrow-band semiconductors. Obtaining and applying the visible-light-active photocatalysts to water and air treatment and testing them in suspension reactors (water purification) and in flat-plate gas-phase continuous flow photocatalytic reactor (air purification) will be the aim of our study. The kinetics of the photocatalytic reactions will be evaluated on the basis of Langmuir-Hinshelwood model both under continuous flow conditions (plug-flow reactor) and under flow-circulation conditions using a gas circulation pump (ideal mixing reactor) to enter the kinetic region. The effect of the thickness of the photocatalytic coating with respect to operation in the diffusion or in the kinetic region will be estimated. Optimal experimental conditions for maximal conversion degree will be selected in view of achieving steady state operation and optimal reactor configuration removing the dead zones.
