| 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. |

| 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, PhD. |
| 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. |

| Insight to local structure of doped/nanocrystalline complex oxides by sophisticated physico-chemical methods. Educational approach. | |
| 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. The project is focused on synthesis and characterization of novel classes of high-entropy oxides. |

| Li +/Na+ pyroxény ako potenciálne materiály pre batériový priemysel | |
| 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. |

| 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. |

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. |

| 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. |

| 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. |

| Project leader: | Mgr. Hagarová Lenka, PhD. |
| 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. |

| 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. |

| 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. |

| Energy interpretation of rock mass strength properties | |
| Program: | VEGA |
| Project leader: | Ing. Lazarová Edita, CSc. |
| Annotation: | Successful mechanized tunnelling of underground structures is determined by range of knowledge on excavated rock mass and suitability of the construction of the full-face tunnelling machine (TBM) for expected natural conditions. Rock mass is an inhomogeneous and anisotropic spatial discontinuum, with only incomplete mathematical descriptions and properties, which have to be determined from a conventional engineering-geological survey. Designed inverse continuous method of the assessment of rock mass properties based on monitored data of tunnelling process complements the usual survey. The method enables to specify the rock environment and outnumbers the data density acquired from conventional survey. Transformations of energetic interpretation of rock cutting by TBM into the problem of energy interpretation of rock mass strength properties would enable to acquire the detailed information for designing stage of constructional phase of the construction within the destructional phase of the tunnel construction. |

| Annotation: | The content of hazardous substances in atmospheric deposition (AD) is one way of their input to individual components of environment. Besides gaseous emissions, both mining and metallurgical industries also produce solid emissions, which by their special composition significantly influence the quality and quantity of inputs from AD, above all in their vicinity. The inputs of selected heavy metals and mineral dispersions into components of environment will be qualitatively and quantitatively determined by analysis and study of samples obtained from monitoring of AD in observed areas. The following areas will be monitored: the area of Nižná Slaná and Jelšava with mining industry and the one of Krompachy and Central Spiš with metallurgical and former mining industries. The solution and results of project bring new knowledges with subsequent possible application in other practical tasks, which require understanding of real level of immission load of environmental components in given area. |

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. |

| 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. |
