Simple and chip low-temperature hydrothermal synthesis at 90oC enables preparation of ZnO films with high optical transparency and low resistivity. The formation of ZnO nucleation layer and an influence of its characteristics on growth and optical properties of the ZnO films were studied. Highly homogeneous and continuous nucleation layer of well-connected ZnO grains with size from 30 to 100 nm, which enable hydrothermal growth of highly transparent ZnO film, were prepared.

A scientific monograph entitled 'Minerals of the mercury ore deposit Idria' was published in three languages, Slovene, German and English, the latter by the renowned international scientific publisher Springer Verlag. Mineralogy is explained in terms of geological processes that were active during the formation of the ore deposit. The central part of the book is dedicated to the main mineral of the ore deposit, cinnabar. It occurs in a variety of crystal forms, of which the most special are lateral interpenetration twins. The book is written for a broad readership, and is interesting for geologists, mineralogist and crystallographers, as well as for those interested in the history of mineral collecting in Idria and represent and important natural heritage of Slovenia.

Studies of hollow metallic nanoparticles produced by PLD in nitrogen atmosphere are becoming an area of high potential for future applications in theranostics. Hollow nanospheres were successfully produced from CoPt, Fe, Fe(Sm,Ta) and Al targets. I have proven and systematically measured the nitrogen gas pressure within the individual Al-based spheres. The nitrogen pressure ranged between 200 and 600 Bars and was generally increasing by decreasing the volume of the void. This is in accordance with the equilibrium gas pressure that would form in a bubble in Al melt considering the corresponding surface energy.

In the field of photocatalysis we designed and fabricated Ti-foil based microreactor with titania nanotubes and anatase nanoparticles. Basic photocatalytic properties and design was published in ACS applied materials & interfaces (IF 5). Using this microreactor we performed series of experiments where we studied the mechanisms of degradation reactions for various types of organic substances. It was found that during the decomposition of organics containing chlorine the efficiency of the microreactor seriously decreased. With EPR measurements we tried to established the mechanism of this phenomena, namely the chlorine could adsorb on the surface of nanoanatase particles and due to steric effects hindered the adsorption of the organic molecules or could produce chlorine radicals which are concurrent to hydroxyl radicals.

In this study we have investigated the kinetic parameters for depositing Fe and Pd and their influence on the Fe-Pd alloy’s composition, while performing the deposition on a flat Au electrode and into a Au-sputtered porous alumina template. The electrodeposition of Fe and Pd was found to be irreversible and diffusion-controlled. Kinetic parameters like the diffusion coefficient, the charge-transfer coefficient, the kinetic constant and the exchange current for both metallic ions in the porous alumina template and on the flat electrode were determined via voltammetric and chrono-amperometric analyses. We found that the diffusion coefficient is smaller for both ions when the template is used as a working electrode due to the high aspect ratio of the pores.
