stability, the equivalency between accelerated ageing tests and natural ageing of materials is determined. The
method will be applied for the life-time prediction of materials under extreme conditions, i. e. in automotive
industry and nuclear power plants. Experimental results will be interpreted using theoretical models involving
kinetics, thermodynamics and statistical thermodynamics of processes with the implementation of modern
mathematical approach, such as the fractal theory and neural networks.

ELECTRON STRUCTURE AND PROPERTIES OF MATERIALS IN SOLID PHASE (Jozef
Kožíšek)
The ambition of the solved project is the integrated study of the selected systems in solid state with possible
applications in understanding the mechanisms of enzymatic reactions in biological systems, developing new
materials (spin cross-over systems), or catalysts for asymmetric synthesis. Project benefits from just developed
laboratory for studying electronic structure (GEMINI R diffractometer, 16-processor cluster), running EU project in
HASYLAB/DESY (synchrotron radiation), as well as the possibility to make data collection on neutron sources
(Garching, Grenoble).
Project duration: from 2005 to 2007
Liquid fuels based on vegetable oils and animal fats for transport and energetics (Ján
Cvengroš)
Project is focused on the study of non-traditional utilization of natural triacylglycerols (TAG) as liquid fuels for
transport and energetics, hydrogenation cracking of TAG, utilization of mixtures naphta and ethanol and/or TAG
as diesel fuels,energetic utilization of glycerol. The targets of the project are as follows:
- Study of natural TAG hydrogenation cracking and hydro-isomerisation, complex analysis of products and their
blends with fossil fuel, process optimization, documentation for application.
- TAG or TAG + bio-ethanol blend as a fuel for non-adapted / adapted diesel fuel, laboratory and bench engine
tests neat / additived TAG / TAG + bio-ethanol, TAG treatment, optimization of treatment. Blended fuel TAG +
fossil fuels for diesel engines.
- Laboratory and engine tests of blends fossil fuel + bio-components (ethanol, ethanol + FAME), their parameters,
additived for improvements of the parameters of mixed fuel.
- Energetic utilization of GP or partly refined G, direct combustion of highly pre-heated GP or G by spraying
through nozzles in combustion chamber, combustion of GP/G as blended fuel with fossil component or methanol.
Project duration: from 2006 to 2009
Basic characteristics of horizontal evaporator with wiped film (Ján Cvengroš)
Model study of evaporation, distillation and film flow in horizontal evaporator with wiped film. Basic characteristics
of horizontal evaporator whit controlled residence time of liquid on evaporation surface. The influence of selected
design parameters (wiper, evaporation surface) and operational parameters (feed rate, viscosity, peripheral speed
of wiper, pressure, temperature, evaporation degree) on the evaporator performance.
Project duration: from 2004 to 2006
Antioxidant and prooxidant properties of carotenoids - EPR study (Marian Valko)
Carotenoids are pigments that are found in plants and microorganisms and may prevent or inhibit certain types of
cancer, atherosclerosis, age-related muscular degeneration, and other diseases. The protective role of
carotenoids is related to their antioxidant ability to efficiently scavenge free radicals. The main objective of this
project is to perform a comparative study of antioxidant efficiency of several carotenoids to scavenge oxygen free
radicals in solution. However, recent epidemiological studies have surprisingly demonstrated that some
carotenoids can also exhibit prooxidant properties. In this connection we plan to investigate the most important
factors, such as concentration, role of trace metals (Cu 2+ , Fe 2+ ), isomerism and oxygen partial pressure (pO 2 ),
which affect a switch between antioxidant and prooxidant behaviour of carotenoids using EPR spectroscopy. In
particular the role of cis-trans isomerism within the conjugated chain, which recent biochemical experiments
suggest might have a very significant effect on activity, has received little attention.
