Description of the expertise offered
The results of work at our department are divided into 3 points: 1.) We have a model describing water infiltration and contaminant diffusion in porous medium. By inverse method we can determine physical properties – coefficients present in this model. Application: When the escape of the contaminant from waste materials occurs we can determine parameters of porous medium in which the contaminant propagates, and therefore also we can determine the evolution of contaminant propagation in given media. On this problematic we have a grant APVV in 2010-2014. 2.) Physical properties of building porous materials. - Experimental investigation of thermophysical properties by 1.) Pulse method 2.) Controlled experiment – by inverse methods. - Experimental investigation of elastic properties dependent on temperature and moisture (Temperature and moisture are changed simultaneously. I accent, that commercial dilatometers have only temperature dependances). On this problematic we have a grant VEGA in 2013-2015. - Experimental investigation of electrical and dielectric properties. 3.) Chalcogenide glasses. - The theory of transport properties of chalcogenide glasses was published (and it is being improved). - Experimental investigation of electrical and optical properties of chalcogenide glasses.
