Study of electrical and impedance characteristics of thermally stressed dielectrics 

In the course of the research, the student will become familiar with the current status of insulation materials and their behaviour at low, room and high temperatures. The research will lead to the design and development of methods that can be used to continuously monitor the insulation properties of the dielectrics and to predict the practical lifespan of the insulators and their resistance to extreme temperatures. The principal experimental method will be the measurement of complex impedance at variable temperatures as well as the measurement of DC resistance and loss factor at 50 Hz. The methodology will be supplemented by monitoring ageing due to sunlight exposure.

Redox flow cells for energy storage

In this work, the students will learn the current issue of storing energy through electrochemical redox flow cells. The experimental work will lead to the improvement of electrochemical cells based on the principle of reduction of vanadium compounds and to design and development of cells with new types of redox systems eventually aimed to replace the vanadium cells.

Optical and electrochemical monitoring of the state of charge of electrochemical cells

In this work the students will become familiar with current issues in energy storage electrochemical redox flow cells and with monitoring the extent of their state of charge. The research will lead to the design and development of methods that can be used for continuous monitoring of the state of charge status. Two basic principles will be used: first, optical tracking in those systems where the spectrum varies coloration due to state of charge, and second, in the absence of optical changes,  measuring electrochemical properties.

Modelling of the dependence of measured electrical and electrochemical material properties on the actual physical shape and dimensions of the studied samples

In this work the student will become familiar with problems of electrical and electrochemical measurements (especially impedance, voltage and current distribution on the electrodes and the flow of material in electrochemical cells). The student will concurrently learn the principles of computer modeling through the method "Finite Elements Modelling" while using commercial software. Computational research will lead to the clarification of the best practice for practical measurements, proposals for possible new practical geometry and the feedbacks to colleagues who are developing samples of functional designs.
