Ing. Lazarová Edita PhD. |
| 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. |

prof. RNDr. Baláž Peter DrSc. |
| Annotation: | The sicentific project will be aimed at modification of the properties of selected minerals by mechanochemical treatment. Intensive milling generates changes of many physico-chemical properties which can be utilized for advanced applications in several branches. For environmental application the ability of activated silicates to sequestrate the carbon dioxide will be used. The same ability manifest the oxides and the carbonates by sorption of toxic metals from soltions. Two-step decomposition of sulphides leads to application in nanotechnology by preparation of the nanocrystalline copper. Mechanochemical synthesis of the synthetic minerals (sulphides, selenides, titanates) in nanosize dimensions can find application in materials engineering. Nanosuspensions of arsenic sulphide show the new-in Europe till now not studied-positive effect by elimination of cancer cell. |

| Annotation: | The nonequilibrium structure of the near-surface layers and the grain boundary regions in novel nanocrystalline oxides (mullites, perovskites, olivines, garnets) prepared via mechanochemical routes will be systematically investigated. The comparative spectroscopic studies of the local structure of bulk and nanosized oxides will enable us to separate the surface/interface effects from the core/grain effects in oxide nanoparticles. An attempt will be made to quantitatively characterize the far-from-equilibrium structural state of surfaces/interfaces in terms of the nonequilibrium cation distribution, the canted spin arrangement, the modified nearest neighbor cation configuration, and the deformed polyhedron geometry.
The particle size dependent magnetic properties of the mechanochemically prepared and subsequently thermally treated nanooxides will be studied with the aim to contribute to the understanding of the structure-property relationships in nanocrystalline solids. |

| Annotation: | Bacterial iron reduction and dissolution are highly regulated biochemical process. This scientific area represents one of unknown and few investigated areas of microbial ecology, and is one of central importance to the propose proceedings for the utilization of biotechnology. The knowledge of bacterial activity in iron cycle can provide different directions of exploiting in improvement quality of non-metallics, sediments, soil, iron coated filters and wastes. The bioavailability of Fe(III) is increased in environments that are rich in organic compounds
including humic substances and chelating agents. The iron-reducing bacteria are thought to play an important role in the cycle of iron and carbon, and also in the bioremediation processes of organic and metal contaminants. Unsterile condition gives a phylogenetic diversity of Fe- reducing bacteria; it is likely that more than one strategy for iron mineral dissolution exists and will be studied. |

| Annotation: | The project is focused on two components of environment in specifically loaded areas, i.e. the atmospheric deposition in the areas of the central Spiš and the Košice city and the bottom sediments of the water-work Ružín.The purpose is to determine the current and real stage of loading in the investigated areas by quantification of observed pollutants mass flows based on the monitoring of atmospheric deposition. On the basis of study on solid
component of deposition the ability of its mobility will be assessed and the hazards for the other components of environment arising therefrom will determine using extraction methods. The forms of occurrence and bond of
selected heavy metals, their mobility, bio-facility and ecotoxicity from viewpoint of possible interaction(autochthonously and/or allochthonously) with the other components of environment will be studied in bottom sediments by extraction methods and toxicity tests. On basis of obtained results a possibility of sediments utilization will be evaluated. |

| Project leader: |
Ing. Danková Zuzana PhD. |
| Annotation: | The aim of the proposed project is the study of natural materials properties used as components of the mixture sorbent in the process of the removal of heavy and toxic metals from the water environment. The compounds of the mixture material will consist of bentonite and quartz sand modified by precipitated metal oxides on their surfaces. Modifications of the bentonite and quartz sand, characterized by the changes in their structural, surface and porous properties will serve new sorbents, whose sorption properties will be evaluated through the experiments. Using the bacterial cell adhesion on the studied modified minerals surfaces is aimed at the next enhancement of the sorption properties of the mixture components. Sorption-diffusion parameters of the powdered mixture obtained from the column experiments in dynamic conditions will be important for the optimal ratio of mixture components. From the stimulation of bacterial coverage by nutrients, the regeneration of sorbent is expected. |

Ing. Labaš Milan PhD. |
| Annotation: | Mechanical disintegration including rotary drilling is characterized by an interaction of indentor and disintegrated material. Interaction consists in the rock disintegration as a beneficial process and in tool wear as an unfavourable process. During the disintegration, the indentor is pushed against the rock surface and concurrently performs a pre-defined motion (advance- or rotational motion) according to the type of applied tool. 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. |

| Program: |
APVV |
| Project leader: |
Ing. Václavíková Miroslava PhD. |
| Annotation: | Intensive industrial activities as well as old pollution represent serious threat to the environment. Among them, heavy metals became priority pollutants due to their non-degradable character. They dissociate in aqueous environment and their forms (cationic or anionic) depend on physical and chemical properties of the system. The objective of the project is the synthesis and investigation of sorbents based on Fe oxides, natural and synthetic modified porous materials as well as microorganism for the removal of heavy metals ions from aqueous media. Besides the cation exchange capacity, the attention is given to the less investigated anion exchange capacity of mentioned materials. The main goal of the project is the selective elimination of heavy metals ions from waters and their bioremediation. The reuse of remediated metals in the industrial applications significantly contributes to the development of environmental friendly technologies. The considerable attention is also given to the investigation of Fe-nanooxides prepared by microbial activity and their applications in the selective sequential precipitation. |
