Galvanic electrocatalytic layers in water alkali electrolysis

Hnát Jaromír, Ing. Ph.D. ( h...@vscht.cz)
Zemanová Matilda, doc. Ing. PhD. ( mat...@stuba.sk)
The aim of this project is development of an efficient electrocatlyst for cathodic hydrogen evolution reaction (HER) in an alkaline environement based on galvanic modification of the Ni substrate. After identification of the optimal coatings properties and deposition method the techniques will be transferred to the 3D porous electrodes to enhance process efficiency and tested in a laboratory and pilot scale alkaline water electrolysis cell.

Optimization of Electrochemical Ferrates(VI) Synthesis

Bystroň Tomáš, doc. Ing. Ph.D. ( bys...@vscht.cz)
Híveš Ján, prof. Ing. CSc. ( jan...@stuba.sk)
The aim of this project is characterization of chemical and electrochemical oxidation processes taking place at the surface of an anode made of iron based materials in strongly alkaline solutions. Deeper understanding of mechanism of these processes allows to enhance efficiency of synthesis of Ferrate (VI) making it economically viable.

Mathematical models of composite materials prepared by dispersing solid particles of a filler in a liquid polymer matrix

Čapek Pavel, doc. Ing. CSc. ( cap...@vscht.cz)
Van der Bruggen Bart, Prof. PhD ( bar...@cit.kuleuven.be)
The work is aimed at the mathematical modelling of composite materials, the preparation of which includes the creation of a suspension of solid particles in a liquid mixture of a solvent and a polymer precursor, volume contraction of the suspension caused by evaporating the solvent and by forming a solid polymer matrix. The initial suspension is modelled using the random sequential addition of particles of various shapes. Then, the motion of particles of the filler in the shrinking suspension is simulated. Each model microstructure and the corresponding microstructure of the real composite material sample are characterised using statistical measures and these measures are subsequently compared with each other for the quality of the model to be evaluated. The real microstructures are deduced from digital images of their polished sections that are observed using a scanning electron microscope.
