| CLEANWATER – Multifunkčné udržateľné adsorbenty na úpravu vody pomocou plazmových technológií a na ochranu zdravia pred xenobiotikami | |
| Multifunctional sustainable adsorbents for water treatment assisted with plasma technologies and for health protection from xenobiotics | |
| Program: | Horizont Európa |
| Project leader: | Melnyk Inna, PhD. |
| Annotation: | Contamination of drinking-water is an urgent global health concern, preferentially in rural areas, and is highly related to the poor and vulnerable population. This challenge requires a single, easy to handle and low-cost solution able to decrease the levels of pathogens, chemical and radiological hazards to tolerable levels in a single and simple pot (from a sorbent on a glass to a more powerful cold plasma technology). Furthermore, climate change, natural disasters and the actual war in Ukraine urges having available fast effective solutions to avoid the spread of waterborne epidemies and being exposed to unsafe levels of heavy metals or hazardous organic pollutants. The complexity of such contamination including organic/inorganic species, cationic/anionic species, different size and shape, etc., requires a multicomponent system and/or device, in the form of a tablet or monolith, able to tackle specifically each of these hazards at once. In addition, this multicomponent system, besides tacking the problem in water, can be prepared and/or modified to be biocompatible so that it can also be used as a dietary complement to mitigate/remove all these hazards in human body (as enterosorbent). Based on these premises, the main goal of the CLEANWATER project is the design and development of multicomponent sorbents prepared by the combination of safe materials (e.g., activated carbons, bone-chars, pectins, among others) able to eliminate these contaminants in drinking water in a single pot or in combination with cold plasma for complete destruction. Furthermore, this sorbent will be modified accordingly to be applied in human body as a dietary complement to remove these species once assimilated in the body. |

| Zero-waste valorisation of feldspathic ores: Green application and sustainable sourcing of strategic raw materials. | |
| Program: | ERANET |
| Project leader: | Mgr. Achimovičová Marcela, PhD. |
| Annotation: | Feldspathic ores containing mainly K-Feldspar (KAlSi3O8) will be valorised by applying several hydro- and pyrometallurgical processes at which KCl, Al2O3, and SiO2 will primarily be produced without generating any solid waste. Objective is to provide new resources for potashand alumina. Targets are to produce fertilizer-grade KCl, high purity Al2O3, synthetic SiO2, Ca-silicate, and SiC from one ore and to sequester CO2 on the same ore.Although there are many studies for K and Al2O3 recovery from feldspars and clays, there are no notable commercial attempt to date. Unlike the other KCl and Al2O3 production methods suggested in the literature, manufacturing KCl, Al2O3, SiO2, Ca-silicate and SiC from the same ore without generating any waste is the novelty of this project. Thus, innovative aspect of the project is that feldspathic ores will be processed as a source of high value-added materials for the first time and with zero-waste approach, thus increasing the economic value of the proposed process. Also, CO2 sequestration capability of the feldsphatic ores will also be verified to enhance the economic importance those types of resources. For increased raw materials efficiency, a novel, hybrid and zero-waste processing method will be put forward. This will be established by exploiting the ores, other than bauxite and natural potash ores, and by applying environmentally sensitive production processes. The project will unlock substantial volume of various raw materials from deposits that cannot be economically or environmentally exploited within or outside the EU through enabling the better efficiency of exploitation of raw materials’ resources and increasing the range andyields of recovered raw materials; and push Europe to the forefront in the area of raw materials processing technologies and increase availability of recovered raw material and create added value products through reducing the amounts of industrial tailings to be disposed or landfilled. |

The combustion of new materials in SHS processes will be studied under stationary conditions and conditions of centrifugal acceleration, which will improve the accuracy of calculations of mixed systems for use in rocket fuels.The second program is aimed at the development of new adhesive additives to bitumen based on ash from thermal power plant dumps (inorganic additives), as well as waste from fat and oil production (organic additives). The separation of the carbon part of the ash from the mineral and their mechanical activation will increase the affinity of the activated material for both bitumen and stone fillers; this will improve the stability of road surfaces. The use of oil and fat industry waste will reduce the cost of organic additives.The third subprogram will develop technical documentation for a plasma torch and a plasma-chemical reactor for processing industrial and municipal solid waste; The plasma torch and the plasma-chemical reactor will be manufactured and tested. The developed reactor will have a fundamental difference from existing analogues.In the fourth subprogram, new catalytic systems will be obtained by impregnation, solution combustion and SHS, for the conversion of greenhouse gases into synthesis gas; in addition, the technological process of catalytic conversion will be optimized. The industrial use of the results of the subprogram will, firstly, reduce the negative impact of greenhouse gases; secondly, demanded raw materials (synthesis gas) will be obtained. |

| Výbuchy v guľových mlynoch – využitie mechanicky vyvolaných samošíriacich sa reakcií na syntézu materiálov | |
| Explosions in ball mills – utilizing mechanically-induced self-propagating reactions for materials synthesis | |
| Program: | SAS-UPJŠ ERC Visiting Fellowship Grants |
| Project leader: | RNDr. Baláž Matej, DrSc. |
| Annotation: | Mechanochemical synthesis utilizing tools of high-energy ball milling is a solvent-free, sustainable, and environmentally friendly synthetic methodology applied in multiple areas of chemistry. Inorganic mechanochemistry, albeit being the older branch, is currently in the shadow of its organic analogue. The aim of this project is to bring a renaissance to this field via the investigation of mechanically induced self-propagating reactions (MSR), which offer the possibility to prepare inorganic compounds via controllable explosive reaction pathways in very short time. This possibility will be demonstrated on the synthesis of metal chalcogenides (MCs), a group of semiconductor compounds containing Earth-abundant elements with multidisciplinary applications. The conventional syntheses of nanocrystalline MCs (e.g, solvothermal or high-temperature one) are time-consuming and energy-demanding, as they require the use of solvents and external heating/pressure. This can be avoided by using the blitz mechanochemical synthesis via MSR proposed here. This field is rather unexplored and thus needs fundamental studies aimed on the understanding of the phenomena behind. This seems to yield a concept that should widely be applied as a completely new synthesis tool for a wide array of compounds. |

| Program: | Mobility |
| Project leader: | RNDr. Fabián Martin, PhD. |
| Annotation: | Functional properties of advanced materials are significantly influenced by their preparation including size of crystallites and formation of defects. Apart variety of several groups of materials, complex and/or doped oxides are still widely used and studied because of high variety of applications. Nevertheless, the synthesis procedure contributes to their applications as it can influence their structure, size, morphology, formation of vacancies, structure distortion etc. Synthesis of materials by ball milling is considered to fast and simple method for preparation of oxides of various composition and structures with modified structures. However, standard available X-ray diffraction methods are often unsufficient to get insight real structure of prepared materials. In this context, spectroscopy methods provides very detail information on local structure of investigated samples.

One of the alternatives for synthesis of inorganic materials offers mechanochemical synthesis, very oftenresulting in nanoscale products, that are prepared by solvent-free method and in relatively short reacting time without post-heating. This is in hand with novel trends indeveloping simpler processes for the synthesis of solidstate reactions of oxides that avoid high-temperature processing. Moreover, the high-energy ball milling cancreate defects that affect the final properties of products.

| Li+/Na+ pyroxenes as potential materials for energy storage industry | |
| Program: | Bilaterálne – iné |
| Project leader: | Mgr. Skurikhina Olha |
| Annotation: | This project is aimed at preparation on novel pyroxenes (LiTiGe2O6, NaTiGe2O6) that are potential non-toxic, cheap and safe alternatives electrode materials. The pyroxene structure (M2M1T2O6) consists of alternating layers of tetrahedra (TO4) and octahedra (M1O6), that create three-dimensional structure with channels for the mobility of M2 cations (Li, Na). The feasibility of commercial application of such materials is under question due to low conductivity and slow Li intercalation. The preparation of new pyroxenes with GeO4 instead of SiO4 will exploit the benefit of the stable 3D structure but in the same time will facilitate the movement of the small M2 ions due to higher elasticity of bonds in GeO4 compared to SiO4 (with retarded rate of M2 diffusion). The new pyroxenes will be prepared using the high-energy ball milling, sustainable and fast synthesis route of solid materials, which allows reducing the sintering time and temperature. Moreover, it enables the preparation of counterparts in far-from equilibrium state (nanoglassy). This approach enables to increase the capacity by particles downsizing and increase the conductivity due to the structural disorder. By solid-state impedance spectroscopy I can establish the potential of LiTiGe2O6 and NaTiGe2O6 pyroxenes (crystalline and far-from equilibrium form) as electrode materials. The use of of Potenstiostat will help to establish the electrode properties of these materials for their practical application in LIB and SIB. |

| Li-ion dynamics in complex oxides prepared by mechanochemical route | |
| Program: | Bilaterálne – iné |
| Project leader: | Mgr. Skurikhina Olha |
| Annotation: | Pyroxenes with chemical formula M2M1T2O6 have shown the potential as cheaper and ecologically friendly alternatives for cathode materials. Silicate pyroxenes (LiFeSi2O6 and LiVSi2O6) were investigated for that purpose but did not show sufficient rate of Li+ insertion during charging-discharging process. One of the reasons is the rigidity of chemical bonds in [SiO4] tetrahedra that hampers the process. In the framework of this project, ion mobility of selected pyroxenes (LiFeSi2O6 and LiFeGe2O6) prepared by non-conventional mechanochemical process will be studied for the first time by impedance spectroscopy. Mechanochemical approach will be used for the induction of (nano)glassy state in these materials. The effect of milling on crystallinity thus the Li-ion mobility will be studied by EIS and XRD. |

| Alternative methods of biocompatibility assessment of porous materials developed for the bone tissue regeneration | |
| Program: | APVV |
| Project leader: | RNDr. Baláž Matej, DrSc. |
| Annotation: | The presented project solves the issue of in vitro testing of an innovative porous materials and their subsequent invivo biocompatibility testing without or with seeded cells in relation to bone tissue regeneration. The scientific levelof the project is increased by so far little-studied connection between the material seeded with endothelial cells andpreviously formed capillaries with the surrounding vessels of the chorioallantoic membrane (CAM) of the birdembryo. The project intensively uses available alternative in vitro and in vivo models with respect to thepreservation of the 3Rs principles, thereby following the current trend in the field of science and research. Thanksto this trend, it will significantly contribute to reducing the number of experimental animals in the biocompatibilityevaluation process. At the same time, the project supports a multidisciplinary approach, as it links in vitro and invivo monitoring of the biocompatibility of prepared materials and biomaterial engineering, which will enable a betterassessment of the use of biomaterials in medical applications. An important point of the project is the effort tocreate a vascularized and therefore viable bone tissue construct important not only for the field of implantology butalso for the creation of tissue models for developmental, physiological, pathological -physiological and otherbiomedical studies. The creation of a vascularized tissue substitute, including a complex of porous material withcells and connecting the capillary bed of the construct to the vascular system of the recipient would significantly push the boundaries of tissue engineering in a positive direction. The project should therefore provide relevantanswers to questions regarding the ability of biomaterials to stimulate the formation of new blood vessels orwhether the newly created construct with cells is suitable for the formation of a bone tissue model in vitro or ex ovo. |

| Project leader: | Melnyk Inna, PhD. |
| Annotation: | Water purification is an essential area of research in the 21st century, in line with the principles of the 2030Agenda for sustainable development. This project aims to contribute to these efforts by developing progressivenanomaterials based on Si, Fe, and Zn oxides for removing organic pollutants from water. To achieve this, rawminerals such as kaolinite, talc, and pyrophyllite, which are widely available in the SR, will be used as sources ofSiO2. In addition, the research will focus on synthesizing functional magnetic adsorbents and catalysts based onFe oxides and photocatalysts based on ZnO. By modifying these materials with various functional groups andmetal ions, their surface properties can be improved, and their selectivity can be enhanced to effectively adsorborganic pollutants. These materials will be applied to eliminate and decompose various organic pollutants,including polyaromatic hydrocarbons and halides from mine waters, azo dyes from the textile industry, drugresidues from wastewater. |

| Synthesized minerals with the structure of complex oxides as components for devices for green energy production and storage | |
| Program: | VEGA |
| Project leader: | RNDr. Fabián Martin, PhD. |
| Annotation: | The issue of the development of sustainable energy sources is one of the most intensively researched scientific areas today. However, addressing this issue requires a comprehensive approach. One of the possibilities is the synthesis and modification of new materials based on minerals with a structure of complex oxides. It is known that complex oxides have a wide range of applications as components for energy generating and storing equipment. Nevertheless, the influence of the modification of the composition, structure, variations in the size of the crystallographic grains and the contribution of the active surface on the functional properties of the studied materials still requires intensive research. Therefore, within the solution of the project, complex oxides of various structural and chemical compositions (especially with perovskite and spinel structure) will be synthesized and investigated utilizing milling of precursors and investigated by standard methods used for the characterization of minerals. |

| Microwave Energy Utilization in the Removal of Toxic Pollutants from Model Solutions, Mine Drainage and Industrial Waste Decontamination. | |
| Program: | VEGA |
| Project leader: | RNDr. Zubrik Anton, PhD. |
| Annotation: | The project is focused on the preparation of advanced carbon adsorbents from local precursors (e.g. Slovak lignite, waste biomass). Microwave heating will be applied in the pyrolytic synthesis of the adsorbents, their surface activation, and modification, as well as in the regeneration process. The modification will be realized by incorporating magnetic nanoparticles (Fe (0), Fe-oxides) into carbon structures. It allows the separation of the solid adsorbent from the cleaned water by magnetic filtration. In addition to the static adsorption experiments, the dynamic mode will be applied during the adsorption studies to eliminate selected toxic metals/metalloids and organic pollutants. Desorption and regeneration of adsorbents as well as microwave degradation of organic pollutants will also be examined. The main goal is to prepare the advanced material with excellent surface properties applicable in the environmental technologies e.g. for remediation of mine drainage and industrial wastes. |

| Project leader: | Melnyk Inna, PhD. |
| Annotation: | Drinking water problems persistently present significant challenges on a global scale, profoundly impacting the health and well-being of millions of individuals. The contamination of water sources, resulting from industrial waste, agricultural runoff, and inadequate sanitation practices, further jeopardizes the quality of drinking water. The UN\’s SDGs 6 and 14 specifically aim to ensure the availability and sustainable management of water and sanitation for all. In line with these objectives, the proposed project will address tasks aligned with these goals, specifically focusing on the creation of materials for water purification and the determination of pollutants in water through the development of sensors. The basis of these substances will be silica, which will be prepared from silica-containing minerals. To create adsorbents (for the removal of a large amount of organic and inorganic pollutants), various organic and complexing groups will be introduced into the surface layer, along with combinations of them. To create catalysts (for the degradation of small concentrations of organic pollutants), transition metals and rare-earth elements will be fixed on the surface of such carriers. The sensors will contain luminescence-sensitive organic groups within the matrix. Such a comprehensive approach will help solve many problems related to water purification |

| Unlocking the innovative potential of silica/pectin composites as environmentally friendly adsorbents for water treatment | |
| Program: | Plán obnovy EÚ |
| Project leader: | Mgr. Kyshkarova Viktoriia, PhD. |
| Annotation: | The primary objective of this project is to develop silica/pectin composites as sorbents. Our approach stands out in recycling waste materials to obtain the necessary components for the desired composite: silica derived from minerals and pectin sourced from agricultural by-products. This approach ensures both environmental sustainability and the renewability of the manufacturing process. Pectin was chosen as a crucial component due to its abundance and the presence of numerous carboxyl groups. These groups exhibit the ability to form complexes with metal ions, thereby enhancing the overall sorption capacity. The utilization of pectin as an adsorbent offers environmental benefits owing to its natural origin and biodegradability. To further improve its adsorption properties, techniques such as chemical modification, cross-linking, and blending with other materials, specifically silica in our case, can be employed. These modifications enhance the adsorption capacity, selectivity, and stability of pectin for specific applications. The main focus of this project will be on the removal of heavy metals from water, considering the biocompatible nature of the composite components. |

| Project leader: | Mgr. Hagarová Lenka, PhD. |
| Annotation: | According to the Critical Raw Materials List (2023), the European Union\’s (EU) reliance on antimony has reached 100%. However, some countries have antimony resources, such as Slovakia, which has more than 3 Mt of antimony available. This project deals with recovering critical raw materials (CRMs) with a primary focus on antimony by advanced biotechnological methods considering the environmental aspect. The main aim of this work is bioleaching of primary CRM source – polymetallic Ag-Cu-Sb-siderite ores/tetrahedrite concentrate from Rožňava (Slovakia) by acidophilic iron-oxidizing bacteria at ambient temperature using a stirred slurry and percolation column techniques. The bioleaching represents one of the environmentally less demanding yet energy-efficient ways of extracting metals comparing to conventional mineral separation and chemical processing routes like alkaline leaching with Na2S. |

Acid mine effluents are a long-standing problem in the region, and waters containing metals pose a high risk to the environment and human health. There is therefore a significant room for modern innovative approaches in the MinePig project, where environmental burden is perceived as an opportunity that creates value in the form of secondary mineral raw materials. These raw materials are presented in the MinePig project as mineral pigments in the form of a powder that is suitable for direct use. |

| Program: | APVV |
| Project leader: | Mgr. Lukáčová Bujňáková Zdenka, PhD. |
| Annotation: | The project deals with development of novel multifunctional media for contemporary photonics, IR optoelectronics, telecommunication and sensing technique, as well as biomedicine based on mechanically activated nanostructured amorphous arsenic selenides, na-As-Se (nano-arseno-selenides). The coupled nanostructurization–re-amorphization effects in these substances activated by high-energy milling in dry and wet modes will be recognized in compositional domains including under-stoichiometric, stoichiometric (As3Se3) and over-stoichiometric substances. The quantum-chemical ab-initio models of covalent-network clusters in As-Se system, complemented by structural re-amorphization probes on short- and medium-range atomic ordering (employing X-ray diffraction related to the first sharp diffraction peak, XRD-FSDP) and sub-atomistic free-volume voids (employing positron annihilation spectroscopy in lifetime measuring mode (PALS) developed within the Positronics approach), allow selection the most perspective na-As-Se with optimized exploitation properties for multifunctional applications. This project is grounded on hypothesis that optimal functionality of mechanically activated glassy arseno-selenides is governed by their atomic-specific and atomic-deficient microstructure, i.e. arrangement of both atoms and atomic-deficient free-volume spaces. That is why PALS, probing free-volume imperfections in a condensed matter at the levels stretching far below experimental measuring limits of many conventional microstructural probes, complemented with atomic-sensitive XRD-FSDP method, are the best tools to through more light on the essence of this phenomenon. This collaborative research is opening novel direction in the engineering of the modern multifunctional solid-state media with predicted, guided and reliable exploitation properties, these being mechanically activated nanostructured glassy arseno-selenides in re-amorphized state – nano-arseno-selenides, na-As-Se. |

| Project leader: | Ing. Ficeriová Jana, PhD. |
| Annotation: | Complicated technological treatment of gold-containing concentrates and non-ecological methods of their processing have initiated the use of a non-traditional environmental method of this precious metal recovery. For these reasons, the scientific project is focused on gold obtained from concentrate White Hill (Detva) by using algae and mechanical activation. Mechanical activation of the concentrate and silica shells of freshwater algae causes changes in the physico-chemical properties of gold carriers as well as mineral components of algae. These structural changes have a decisive influence on the precipitation of nano-size gold into solutions of environmentally friendly reagents, from which the gold is subsequently fixed in the cell matrix on mechanically activated silica algae shells. The gold nanoparticles obtained in this way can have a very important benefit in practice for the disposal of hazardous substances in the environment. |

| Annotation: | Recently, green technologies have attracted much attention due to environmental concerns. The project is focused on the verification of three strategies of silver selenide, Ag2Se mechanochemical synthesis, which is nanostructured semiconductor and perspective thermoelectric material. One-step direct synthesis from the precursors AgNO3 and SeO2 and two other two-steps synthetic pathways will be studied, whereby in the first step, Ag nanoparticles will beprepared by milling-induced reduction using a chemical or biological reducing agent. These hitherto unrealized processes represent a simple, low-cost, environmentally friendly, and solvent-free method with the potential for largescale fabrication of Ag2Se. Innovative energy-saving technology is considered to be a promising way to relieve the impact on the environment. The project includes the monitoring of the kinetics of the proposed mechanochemical syntheses, an evaluation of the phase purity of the prepared products by X-ray powder diffractometry (XRPD), morphology characterization by scanning and transmission electron microscopy (SEM, TEM) and measurement of thermoelectric properties. |

| Gold recovery from refractory sulphide concentrates by mechanochemico-biological activation | |
| Program: | VEGA |
| Project leader: | Ing. Ficeriová Jana, PhD. |
| Annotation: | The demanding processing of gold-containing concentrates, as well as dangerous cyanide method for gold recovery encourage the application of new ways to obtain this precious metal. Therefore, the aim of this project is obtaining gold from refractory sulphide concentrates by using of non-cyanide mechanochemico-biological processes. Mechanochemical activation of concentrates and siliceous shells of specified algae in the non-cyanide environment causes changes in the physico-chemical properties of gold minerals as well as algae mineral constituents. These structural changes have a decisive influence on the formation of gold nanoparticles into non-cyanide media under the specific reaction conditions, from which they are subsequently fixed in the cellular matrix of mechanochemically activated algal shells. Gold nanoparticles can have various utilization in practice, such as accelerating the breakdown of hazardous substances or disposal of pollutants from contaminated water, soil and air. |

| Annotation: | Bacterial strain Acidithiobacillus ferrivorans SS3 belongs to autotrophic iron-oxidizing acidophiles, that play an essential role in the weathering of sulphide minerals e.g. pyrite. The hydrolysis of Fe3+ ion, which is a product of bacterial oxidation, is an acidity producing reaction leading to the formation of secondary iron minerals such as hydroxysulphates (schwertmannite, jarosite). The objective of this project is to describe oxygen and carbon dioxide consumption rates of bacteria and to determine the bacterial growth, iron oxidation kinetics and ferric iron minerals precipitation at suboptimal temperatures simulating the real conditions of AMD (acid mine drainage). The morphology and chemical composition of schwertmannite and jarosite-group minerals will be characterized by SEM microscopy and EDX analyses. The obtained information will lead to better knowledge of acidophilic bacteria-associated reaction in mine environments, their application in hydrometallurgy and water and soil remediation. |

| 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 |

| 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. |

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. |

| 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. |

| 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. |

Complex investigation of the disintegration mechanism of the wear of disintegrating tools in rock drilling shall enable to control the drilling process more effectively. Simultaneous application of direct and indirect methods for wear assessment will allow their comparison and evaluation of the effectiveness of indirect methods for continuous observation of tool wear. Correlations of tool wear and rock properties, primarily of abrasiveness, shall improve the usability of indentor selection and the applied process regime. |

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. |

| 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. |

| 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. |

| Relationships between structure and unusual physical properties in highly nonequilibrium oxides prepared by unconventional mechanochemical synthesis | |
| Program: | APVV |
| Project leader: | RNDr. Fabián Martin, PhD. |
| Annotation: | Nonconventional mechanochemical methods will be used to prepare the far-from-equilibrium novel nanooxides. The studies of the early stages of the mechanically induced nucleation and growth of nonequilibrium phases will provide access to the elucidation of the microscopic mechanism of the nonconventional mechanochemical preparation route. This point represents one of the fundamental but till now the unsolved scientific issues in the field of mechanochemistry/solid state chemistry. Valuable quantitative insights into the atomic and electronic structures as well as into the dynamic and kinetic processes in the mechanochemically prepared nanomaterials will be obtained. Mechanical, magnetic and electric responses of the far-from-equilibrium nanophases will be studied experimentally with the aim to establish the interplay between their local structure and the functional behavior. |
