Using LA-ICPMS and SR-LEXRF imaging techniques for mapping of the Se distribution in sunflower roots (after being fed with Se(IV) or Se(VI)) we have shown that Se(VI) is more mobile compared to Se(IV) which findings will be used in further studies on Se tolerance.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 5144858The goal of this study was to determine the concentration of Hg in soil and accumulation capacity of certain plants. Another aspect of the study was focused on the relation between Hg soil pollution and growth of arbuscular mycorrhizal (AM) fungi. The results showed that Hg concentrations in soil exceeded the critical levels of 10 mg kg-1. The highest concentration of Hg was near the river Idrijca, while the lowest concentration was found in the gardens above the Antonij's mine. The concentration of Hg in plants tissues depended on Hg concentrations in soil, plant species, soil and Hg types. Hg concentrations were higher in the roots than in the shoots. All examined plant species were colonized with AM fungi, however the arbuscule density negatively correlated with increasing Hg concentrations in soil. The highest level of AM colonization and the highest concentration of AM spores were found near the chimney.

COBISS.SI-ID: 9264457The main goal of this thesis was to implement a fundamental study of ablation and deposition processes, i.e. to understand the ejection of the target material in the plume and eventual deposition of the ablated species onto the substrate using two different PLD setups: a commercial laser (213 nm solid state Nd:YAG laser) and a 157 nm molecular F2 laser. A Fe-Sm-Ta alloy (Sm13.8Fe82.2Ta4.0) was used as a target material to study PLD; this material was obtained through induction melting of Fe (13.8 at. %), Sm (82.2 at. %) and Ta (4.0 at. %) via a number of phases (SmFe2, SmFe3, Sm2Fe17, and TaFe2), each with clearly defined boundaries.
