In this article, phase diagram in a ternary system CaO-La2O3-TiO2 at 1400 °C was established. The samples prepared by solid state or wet synthesis route by precipitation, and were characterized with X-ray powder diffraction (XRPD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The structures of several new phases – solid solutions on the tie lines CaTiO3–Ca3La4Ti3O15 and La2TiO5–Ca3La4Ti3O15 – were determined in detail. Related studies have been published in Stare et al.

Oxidovanadium(IV) complexes with cyano, difluoro and hydroxy derivatives of pyridine-2-carboxylic acid and pyrazine-2-carboxylic acid have been synthesized and characterized in solid state and aqueous solution. In organic and aqueous solution of each system an equilibrium of three isomers was observed, and confirmed by DFT simulations. The strength order of the ligands has been determined. Biotransformations in the presence of blood plasma proteins were monitored and in all systems with apo-transferrin (VO)2(apo-hTf) is the main species in solution, with the hydrolytic species becoming more important with lowering the strength of the ligand while in the systems with albumin variety of species were observed depending on the strength of the ligand. Finally, the consequence of the hydrolysis on the binding of (VO2+)-O-IV to the blood proteins, the possible uptake of V species by the cells, and the possible relationship with the insulin-enhancing activity were discussed. Related studies on insulin-enhancing activity with V and Zn species have been published in Koleša-Dobravc et al. New J. Chem. 2017, 41, 735 and the results were presented on invited plenary lecture at International Conferences on Current Challenges in Drug Discovery Research CCDDR 2015, Jaipur, India.

Herein, the magnetic interactions within several related Cu-vanillin-water isomers are investigated. Though all compounds are composed of neutral mononuclear coordination unit building blocks, connected in chains only by the H-bondings, they all show antiferromagnetic interactions. These were analyzed by experimental and theoretical data/calcullations. Such a system shows a rare and crytical example of H-bonding enabled magnetic interaction paths insight for the naturally occuring sistems. Related studies have been published in Kozlevčar et al.

Here, we address three challenges (low efficiency, short lifetime of catalysts and a lack of low-cost materials) by establishing and exploring an intimate functional link between the reactivity and stability of crystalline (CoS2 and MoS2) and amorphous (CoSx and MoSx) hydrogen evolution catalysts. By combining the higher activity of CoSx building blocks with the higher stability of MoSx units into a compact and robust CoMoSx chalcogel structure, we are able to design a low- cost alternative to noble metal catalysts for efficient electrocatalytic production of hydrogen in both alkaline and acidic environments. Results of this paper we also summarized in the review article published recently in Strmčnik, D. et al. Nano Energy 2016, 29, 29–36. The article has been cited 31 times.

Here, we have prepared chemically modified electrodes by modifying Pt with calix[4]arene molecules that are highly stable and can effectively tune the selectivity of anode catalysts for ORR without altering the maximum activity of the HOR. This behavior is highly transformational, extending from long-range-ordered stepped Pt single-crystal surfaces to Pt- polycrystalline electrodes. Above mentioned study shows potential for the commercial use. In this respect we have filed a patent application and done further studies that were published in high impact factor journals: Genorio et al., Angewandte Chemie 2011, 50, 5468-5472, Strmčnik, et al., Nano Energy 2016, 29, 29–36.

This article reports the synthesis of chlorido and pta organoruthenium complexes bearing beta-diketonate ligands. While the chorido complexes showed cytotoxic activity induced through ROS generation the pta analogues displayed cytostatic activity as evidenced by reduced DNA damage and apoptosis induction while they displayed a stronger loss of cancer cell viability over a 72 h drug exposure. This presents the most important findings on the biological and catalytic properties of ruthenium-diketonate complexes, a theme studied by PhD student Sara Seršen who has been awarded the The Krka Award for significant achievements and exceptional dissertation. Related studies have been published in Seršen et al. Organometallics 2013, 32, 609, Traven et al. Chem.-Biol. Inter. 2015, 234, 349 and Seršen et al. J. Inorg. Biochem. 2016, 170, 70.

In this article we presented the synthesis of four novel ruthenium-quinolone complexes bearing the crown thioether trithiacyclononane. The behaviour of the complexes in aqueous solution was investigated and the interavtions with serum albumins and DNA were studied. The inhibitory potency for two enzymes of the cathepsin family and the cytotoxicity against several cancer cell lines were determined. With this article we expanded our studies in the research field of ruthenium-quinolone complexes previously published in Turel et al. Inorg. Chem. 2010, 49, 10750, Kljun et al.

In this article, the BF2 complex of 1-phenyl-3-(3,5-dimethoxyphenyl)-propane-1,3-dione (1), was prepared and its polymorphism was resolved by means of X-ray single crystal structural analysis. Compound 1 exists as two polymorphs having different mutual orientations of the two methoxy groups: in polymorph A away from each other (termed anti), while in polymorph B one methoxy group is oriented toward the other (syn-anti). In both crystals, the molecules which are antiparallel form stacks through face-to-face ?-? interactions, while in polymorph A the crystal packing is further stabilized by hydrogen bonds. That results in numerous chromic effects. The article has been cited 105 times.

The article describes a new innovative synthesis of an anode material (NiO-SDC) from a solution of metal acetates, and ethylene glycol. The influences of preparating conditions including calcination temperature and morphology characteristics, sintering temperature on the final microstructure were investigated using TG, QMS, BET, XRD, heating microscope and SEM microscope. The results were used to prepare a bi-layered anode/electrolyte system. A bi-layer system had an appropriate microstructure of both materials, showed the highest contiguity, excellent contact between phases and no visible cracks. Related studies were described in Skalar et al., Journal of the European ceramic society, 2012, 32, 2333-2339; Skalar et al., Materiali in tehnologije, 2015, 5, 731-738.
