2. Interaction Studies of Nanomaterials with Biological Systems

Supervisor: Mgr. Zdenka Lukáčová Bujňáková, PhD.

Nowadays, huge progress is being made in nanotechnology. New nanomaterials with extraordinary properties applicable in electronics, optics, constructed materials, waste water treatment or medicine are extensively studied and produced. Such nanomaterials come into contact with the environment and humans and subsequently interact with different biological systems (proteins, cells, membranes, organelles, DNA, etc.) and create a so called nano-bio interface. The aim of the thesis will be study of the interactions between selected nanosized materials and biological systems using spectroscopy techniques. The surface modification of nanomaterials with various biocompatible substances and ligands and the considearation of relationships between microstructural, morphological and surface properties and biological activity will also be studied in this work.

 

3. Hydrometallurgy and Mechanochemical Synthesis of Selected Metal Selenides

Supervisor: Mgr. Marcela Achimovičová, PhD.

Selected natural, mechanically activated metal selenides and their synthetic analogues prepared by mechanochemical synthesis will be studied. Mechanical activation and mechanochemical synthesis will be performed in high-energy milling equipments, in mills to find the most suitable conditions for these processes. There will be investigated and compared crystal structures, morphology and physico-chemical properties of natural and synthetic metal selenides in terms of their potential use for solar cells, thermocouples and Li-batteries. The study of the hydrometallurgical treatment of natural metal selenides by leaching to obtain useful metals in solution will bring new insights into the application of this mineral group.

 

4. Novel Lead-free Inorganic Materials for Energetic Industry

Supervisor: RNDr. Martin Fabián, PhD.

The energy sector is the backbone of every economy. It provides stability, independence and prosperity. Nowadays the focus of the European energy policy is the development ol low-carbon technologies. In this context, the PhD topic is focused on synthesis and study of novel green-energy related inorganic materials. Special effort will be
devoted towards preparation of components for Li/Na-ion batteries and Solid Oxide Fuel Cells (SOFCs). Proposed topic combines scientific disciplines of inorganic chemistry, solid state chemistry and preparation of ceramic materials. It will require application of several methods of synthesis of selected inorganic materials and study
of their structure by diffraction (XRD), spectroscopic (Raman, FTIR, MAS NMR,…) and microscopic (SEM, TEM) methods. Electrochemical properties will be investigated within the cooperation of partner institutes in Slovakia and abroad.

 

5. Heavy Metals and Organic Pollutants in Particulate Matter and Atmospheric Deposition

Supervisor: Ing. Jozef Hančuľák, PhD.

The research will be focused on the investigation of dust particles in air, which represent serious environmental and health risks. Field sampling of suspended (PM) and dust particles of atmospheric deposition will be realized mainly in urban and industrial environment. The goal of PhD thesis is to acquire the knowledge on the origin of dust particles related to the anthropogenic and natural sources of their emissions and their effect on selected components of environment, based on the study of specific characteristics of dust particles (chemical and phase composition, size distribution, shape characteristics).

New topics of PhD study in academic year 2018/2019

1. Synthesis and properties of nanocrystalline materials for environmental applications

Supervisor: RNDr. Matej Baláž, PhD.
Consultant: Dr.h.c. prof. RNDr. Peter Baláž, DrSc.

Within the frame of the thesis, nanomaterials of different composition will be synthesized using high-energy milling. Based on the character of the nanoproducts, they will be tested for photocatalytic, sorption or antibacterial activity. For the selected products, also a potential in the application in solar cells and thermoelectric materials will be studied. The environmental viewpoint of mechanochemical approach will resonate in the whole thesis.

 

2. Preparation and study of multicomponent materials for cleaning of leachates originated from the bioremediation process of contaminated soil loaded by metallurgical industry

Supervisor: Ing. Zuzana Danková, PhD.
Consultant: Ing. Alexandra Bekényiová, PhD.

Subsequent toxic elements contamination of soils is one of the main environmental problems of urbanization and industrialization and has recently become a serious concern in the world. The treatment of contaminated soils and sediments can be achieved by either physical or chemical methods. Also a bioremediation has received a great deal of attention in recent years. The reverse immobilization of toxic elements from the leachates originated from the soil bioremediation is interesting for their following utilization in industry. The aim of the PhD thesis will be the preparation of multicomponents materials (natural/synthetized) and study of their properties. These materials will be tested as adsorbents of toxic elements from the real leachates. The leachates will originate from the experimental process of bioremediation of contaminated soil loaded by metallurgical industry (for example the locality Krompachy, which is hazardous due to enhanced contents of mobile forms of As, Cu, Pb, Cd in soil). The study of sorption conditions and properties of particular materials in dynamic regime will allow determining the optimal ratio of filters components. These filters should be used in ex-situ bioremediation process of contaminated soils on heaps for reverse immobilization of toxic elements.

 

3. Heavy metals and organic pollutants in solid phase of aerosols and atmospheric deposition

Supervisor: Ing. Jozef Hančuľák, PhD.

The research will be focused on the investigation of dust particles in air, which represent serious environmental and health risks. Field sampling of suspended (PM) and dust particles of atmospheric deposition will be realized mainly in urban and industrial environment. The goal of PhD thesis is to acquire the knowledge on the origin of dust particles related to the anthropogenic and natural sources of their emissions and their effect on selected components of environment, based on the study of specific characteristics of dust particles (chemical and phase composition, size distribution, shape characteristics).

 

4. Preparation, characterization and physico-chemical properties of complex oxides

Supervisor: RNDr. Erika Tóthová, PhD.

The research will be focused on the preparation and characterization of pyroxenes, i.e. compounds with the general chemical formula M2M1T2O6 where M2 = Li1+, Na1+; M1 = Fe3+ a T = Si4+. Both materials, LiFeSi2O6 a NaFeSi2O6, have interesting electrochemical properties with potential application in  Li-ion a Na-ion baterries. Their conventional preparation is complicated, multistep, time and cost consuming. Mechanochemistry is the field of chemistry focused on the preparation of materials by mechanochemical way, by mechanosynthesis. It is possible to prepare various materials by simple and one-step way at relatively short time. The aim of this work is preparation of these materials by non-conventional mechanochemical synthesis. The influence of various types of starting materials on the kinetic of the process and physico-chemical properties will be studied.

 

5. Composite materials for elimination of industrial contaminants from environment

Supervisor: Ing. Miroslava Václavíková, PhD.

The objective of PhD thesis is the synthesis and study of nanopartcles basod on metal oxides (Fe, Cu) incorporated into porous structures such as activated carbons, alumosilicates, silicates and/or other well organized porous structures. Such composite materials (sorbents) will be tested to remove inorganic and organic pollutants from environment. Moreover, they will be modified by various functional groups to develepe selective active sorption sites towards various contaminants. The sorption capacity as well as stability of the composites will be investigated.
