AB  - Biopolymer emulsions were processed in the form of thin films for application in active food packaging. Active packaging is defined as material designed to release active components into food or absorb them from food in order to extend durability or to maintain/improve packaging conditions and extend shelf-life of food. We synthesized emulsion based on biodegradable polymers (pectin, gelatin, chitosan) with addition of active components -essential oils and ZnO nanoparticles (NPs). By introducing essential oils in the polymer matrix, with the addition of certain emulsifiers, it comes to encapsulation of oil droplets and the formation of a homogeneous emulsion. Thin films were fabricated by mold casting or spraying of the emulsions on a substrate. The slow release of an essential oil from the polymeric matrix was determined by UV-vis spectrophotometry. It was shown that polymers with addition of nanoparticles provided a prolonged action of active components. Surface morphology of the films was characterized by atomic force microscopy (AFM), and it was noticed that nanoparticles were mainly accumulated around oil droplets, which additionally contributed to a slow release of the active components.

AB  - TiO2 (anatase) and Fe2O3 (hematite) nanopowders were mixed in the weight ratio 1:1.5 and 1:2 and homogenized in a planetary ball mill for an hour. After that pastes were prepared of the two powder mixtures, organic vehicle and glass frit. The pastes were screen printed on FTO coated glass substrates and sintered at 800°C/10 minutes. Formation of monoclinic pseudobrookite was confirmed by XRD analysis of the thick film samples. The thick film crystal structure and optical properties were observed by SEM and UV/Vis spectroscopy. Current-voltage analysis was performed on a sandwich structure formed of thick film and two conductive FTO layers (bottom and top).

AB  - Thick films of nanostructured pure TiO2, -Fe2O3, Fe2O3/TiO2 (ratio 2:3 and 3:2) and a hetero-junction in the form of a TiO2 layer over a Fe2O3 layer have been fabricated by screen printing technology on a glass substrate. The pastes used for film preparation were obtained by adding an organic vehicle to the oxide powders together with a small percentage of binding glass frit. Samples were dried up to 100oC and sintered at 650oC/60 minutes. Structural, morphological and optical studies have been carried out using XRD, SEM, EDS analysis and UV/Vis spectroscopy. Fe2O3/TiO2 thick films had a homogenous nanostructure and no new compounds were formed. Indirect band gaps were determined from the measured transmission spectra.
