Program: Medziakademická dohoda (MAD)
Project leader: Ing. Václavíková Miroslava PhD.
Annotation:The joint Ukrainian-Slovak project is supposed to result in the detailed study of the effect of the conditions of magnetite functionalization on hydrophobic and hydrophilic properties of the coating layers. The surface of the obtained materials will be characterized by the presence of different types of dominant groups, specific functional groups selective to particular metal or group of elements; electron withdrawing or electron accepting groups, both from hydrophobic hydrocarbon radicals attached to the silicon atom and from organic groups directly incorporated in the silica framework (it is an organic bridge for bridged silsesquioxanes); residual silanol groups, and oxygen atoms of the siloxane bond. Such nature of sorbents surface will enable different types of interactions with different sorbates.

Mechanism of anti-tumor activity of realgar nanoparticles and its synergism with anti-myeloma agents
Mechanizmus protinádorového účinku nanočastíc realgáru a synergia s anti-myelónovými liečivami
Program: VEGA
Project leader: Mgr. Lukáčová 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.

Program: APVV
Project leader: Dr.h.c. prof. RNDr. Baláž Peter DrSc.
Annotation:The scientific project will be focused on elaboration of the specific mechanochemical routes to synthesize the advanced substances with high level of utilization in nanotechnologies.

Study of physico-chemical properties of nanooxides prepared by combined mechanochemical-thermal synthesis
Štúdium fyzikálno-chemických vlastností nanooxidov pripravených kombinovanou mechanochemicko/termickou syntézou
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.

Multicomponent filters in process of leachates cleaning from the toxic elements after the bioremediation of soils contaminated by metallurgical industry
Viaczložkové filtre v procese čistenia výluhov od toxických prvkov po bioremediácii pôd kontaminovaných hutníckym priemyslom
Program: VEGA
Project leader: Ing. Danková Zuzana PhD.
Annotation:The project involves the basic research oriented on the treatment of leachates containing toxic elements originated from the bioremediation process of contaminated soils. The project continues original methods of soils and sediments bioleaching by heterotrophic bacteria in aerobic and anaerobic conditions studied in previous VEGA project focused on the development of bioremediation technology. The subject of the project is preparation and study of multicomponent filters properties, composed from the natural materials (quartz sand, siderite, pyrite) and synthetic prepared materials (iron and manganese oxides/hydroxides) that will be used for cleaning of leaching media containing toxic elements. The original gain of the project will be the definition of optimal ratio of particular filters components for the most effective recycling of media containing different concentrations of toxic ions in dependence of locality and soil contamination. The greatest accent will be focused on the arsenic removal.

High-energy milling for the synthesis of nanomaterials using bio-approach and selected environmental applications
Vysoko-energetické mletie pre syntézu nanomateriálov bio-prístupom a vybrané environmentálne aplikácie
Program: VEGA
Project leader: RNDr. Baláž Matej PhD.
Annotation:The research project is focused on mechanochemical synthesis of the selected nanomaterials via combination of high-energy milling and green approach using precursors based on minerals, natural materials and waste. Mechanochemical reduction will be aimed at preparation of nanocrystalline metals with bactericide effects (Ag, Cu). At the same time, the project will be focused also environmentally, because the application of mechanochemistry will be tested on elimination of halogenated compounds and sorption of toxic metals present in wastewaters after mining and metallurgical activities. Environmental aspect will also resonate by research of selected organic reactions where solid state approach via mechanochemistry can be realized through solvent-free technology. Available characterization methods will be applied for products characterization and monitoring of environmental parameters. The project broadens the application potential of mineralurgy and also metallurgy.

ZVNI - Development of a system for continuous monitoring of pollution impact on the high-voltage insulation
Vývoj systému pre kontinuálne monitorovanie vplyvu znečistenia na vysokonapäťovú izoláciu
Program: APVV
Project leader: RNDr. Fabián Martin PhD.
Annotation:The dynamics of the environmental pollution is affected by the industrial emissions and the ongoing climate change. The environmental pollution on electrical insulation is one of the problems faced by distribution utilities and electricity transmission system. Moreover, it can be classified as a potential danger for reliable operation of an electric power system. Seasonal conversions affect the tendency accumulation of contaminants on the surface of insulators and cause chemical changes which influence their original characteristics. This fact needs to be addressed, as mentioned insulation is an important part in the chain of the transmission and the distribution systems reliability. Current knowledge points to the fact that, depending on the profile of the insulator, the pollution, 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 are included in the electricity transmission and distribution systems. Nevertheless, at present time in Slovakia no information is gathered about the current state of pollution in key areas of strategic energy objects. The project is focused on the development of modern equipment, enabling real-time monitoring of insulator surface condition either in autonomous mode or as part of an existing network-based IT infrastructure with a remote dispatching control system. This proposal of research and development is invoked by the project implemented within the EU

Program: VEGA
Project leader: RNDr. Dolinská Silvia PhD.
Annotation:The mineral waste coming from mining (mineral processing), metallurgy and coal-fired power industry can be also treated as a significant source of so called critical mineral raw materials or possibly elements. Submitted project proposal includes detailed analysis of the following selected waste from Slovakia: black coal fly ash (Košice), tailings from flotation and polymetallic ore processing (Markušovce), bauxite residuum (dump of red mud after Bayer process, Žiar nad Hronom), from viewpoint of critical elements abundance. On the basis of obtained data physical and physico-chemical techniques of critical elements beneficiation will be proposed. An extraction of critical elements by various chemical agents and an optimization of leaching process will be performed. Chemical and physico-chemical methods will be applied in selective separation of critical elements from leachates. An influence of microwave energy on efficiency of critical elements extraction from waste will be also investigated.
