The subject of this invention is a sol-gel procedure for the preparation of anticorrosion coatings for solar collectors. Core of this invention are processes for the preparation of ultra thin coatings (0.5-500 nm), which do not deteriorate optical properties of surfaces. So protected absobers can be more than 20 days in slat spray chamber. The innovation was awarded by golden prize at Regional competition and golden prize of Chamber of Commerce and Industry of Slovenia for innovation in 2009. There was already submitted the world patent claim. Patent was sold abroad (Alanod, Germany).

COBISS.SI-ID: 4235290Black and coloured (red, green, blue) thickness insensitive spectrally selective (TISS) coatings were prepared for use as solar facade absorbers from polyurethanes. Their low emittance was achieved by aluminium flakes, while black pigment was added to adjust solar absorptance. TISS coatings combine advantages of paints (longevity, chemical resistance, variety of colours, simple application) with their spectral selectivity. The innovation was awarded by silver prize at Regional competition of Chamber of Commerce and Industry for innovation in 2009. Patent was sold abroad (Alanod, Germany).

COBISS.SI-ID: 4562714University of Nova Gorica together with the European Association for Chemistry and the Environment ACE, organized European meeting on Environmental Chemistry EMEC11. The researchers from University were involved as the Chairman f the International Scientific Cmmittee (Mladen Franko) as well as in chairing the Organizing committee (Polonca Trebše). Polonca Trebše, Vesna Lavtižar and Marta Petrič have also taken the opportunity to edit the book of abstract of the conference.

COBISS.SI-ID: 253623296Cooperation of National Institute of Chemistry and Helios led to the development of new spectrally selective coatings for solar absorbers. The result of successful cooperation was awarded by Puh Award for Inventions, Development Achievements and Transfer of Scientific Investigations in Industry, which belong among the highest state awards in the scientific field. New coatings enable mass production of absorption coatings for solar collectors with continuous deposition on aluminium or zincated sheet metal. Absorbers, prepared in this way, are much cheaper than vacuum deposited absorbers.

COBISS.SI-ID: 4562714The patent consists of a general method for the preparation of polyhedral silsesquioxanes. The method includes the application of inorganic or organic hydrogen difluorides and polyether, which has not yet been used for the preparation of polyhedral silsesquioxanes during the conditions of reflux. With this method higher turnovers at lower concentration of catalysts are obtained compared to methods used so far. Hydrogen difluorides as acid catalysts are basically different compared to methods reported until now, where exclusively basic catalysts have been used.
