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.

Various industrial polutants such as heavy metals, radionuclides, petroleum and other substances in waste streams have been identified as highly toxic and harmful to the environment and human health. 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.

 

6. Nanocrystalline oxides. Synthesis, characterization and possible application in industry

Supervisor: RNDr. Martin Fabián, PhD.

Non-conventional synthesis of nanocrystalline oxides mostly by mechanochemical route. Structural characterization by combination of X-ray powder diffraction and spectroscopic methods. Study of functional properties of prepared materials. Optimization of structure based on achieved physical properties.
