1. Synthesis and doping of selected transition metal selenides by high-energy milling for prospective thermoelectrics

Supervisor: Mgr. Marcela Achimovičová PhD.

The thesis will deal with the study of mechanochemical or mechano-thermal synthesis of selected selenides as potential semiconductor materials for thermoelectric generators. Thermoelectric materials have the ability to convert thermal energy, especially to recycle waste heat into electrical energy. The method of metal selenides synthesis by high-energy milling represents an ecological, simple and relatively inexpensive alternative compared to other methods. Kinetics of the syntheses, the crystal structures, the morphology, the physico-chemical properties, and the thermoelectric properties of synthetic metal selenides will be investigated. Doping of synthesized metal selenides by milling will present a promising strategy for optimizing their thermoelectric performance.

2. Mechanochemical evaluation of eggshell waste for the preparation of nanocrystalline minerals with environmental and biological applications

Supervisor: RNDr. Matej Baláž, PhD.

Eggshell waste is one of the most widespread food wastes (its global production is approximately 6.82 million tons per year). As part of the dissertation, it is planned to use this waste as a sorbent for wastewater treatment, while the increase in sorption capacity will be achieved through its high-energy milling in a planetary ball mill (so-called mechanical activation). In addition, eggshell waste will be used as a source of calcium and sulfur for the preparation of nanocrystalline minerals (specifically chalcogenides and oxides). In this case, the waste will be ground together with other reagents (so-called mechanochemical synthesis). The obtained compounds will be tested in terms of their potential application in the fields of photocatalysis, microbiology or thermoelectric materials

3. Functional Materials for the Removal and Catalytic Oxidation of Organic Pollutants from Wastewater

Supervisor: Dr. Inna Melnyk
Consultant: Ing. Miroslava Václavíková, PhD.
The intensive industrial activity results in more organic pollutants, heavy metals, radionuclides, petroleum products, and other highly toxic substances enter to the environment in the form of solid, liquid, and gaseous wastes. In this PhD research, new adsorptive and catalytic nanomaterials will be developed for the removal of inorganic and organic wastes from the environment. The adsorbent part will be composed of one-pot synthesized SiO2 materials with different types of functional ligands both hydrophobic and hydrophilic moieties in order to interact with pollutants via hydrogen bonds, electrostatic interactions, coordination, and other interactions. These materials will be studied for Fe, Cu, Ni, Co ions adsorption. Metal-loaded silica particles will play a catalyst role to decompose the organic contaminants via advanced oxidation processes.
