During the reaction, highly colored radicals are formed as intermediates, which were characterized by EPR and UV-vis spectroscopy. The formation rate and the rate of decay of these radicals were determined kinetically. These radicals exhibit high persistency and under inert conditions can be handled conveniently. Based on detailed kinetic and spectroscopic studies and DFT calculations, a plausible mechanism has been proposed.},

	abstract = {The roles of biologically active transition metal (such as Fe, Cu) complexes with antibacterial, antifungal, and anticancer property have attracted much interest during last decades. Numerous chelates containing Cu2+ have been shown to possess anti-inflammatory activity [1]. Efforts are now focused to develop novel antitumor drugs which can improve clinical effectiveness, in order to reduce general toxicity and to broaden the spectrum of activity. Due to its interaction with many biomolecules and synthetic substances including organometallic compounds and metal complexes, DNA is a main target for the therapeutic treatment of various disorders and diseases [2]. Metal complex based functional metalloenzymes play also an important role as highly active and selective catalysts governing vital functions of living organisms [3].
		In our research project new Fe(II) and Cu(II) complexes were synthesized from the reaction between azomethine derivatives (glyoximes, Schiff bases, semi- and thiosemicarbazones) and Fe(II) or Cu(II) salts, respectively, in suitable solvent. After presenting a short historical survey, classification, and possible application fields of these compounds, we report the study of their thermoanalytical behaviour (TG, DTA, DTG), spectroscopic features (such as FTIR, NMR, UV-VIS, Raman, Mössbauer, ESR spectroscopy, mass spectrometry) as well as their powder XRD. The biological activity of complexes, especially their antibacterial activity, will also be discussed.},

The bidentate coordination mode of the ligands has been found preferentially with cis arrangements in 1 and 2 and trans arrangements in 3-5. The solution speciation and complex stability of aqueous solutions have been studied by pH-dependent electron paramagnetic resonance spectroscopy resulting in the detection of solely monomeric [CuL](+) and [CuL2] complexes. The stability order obtained for the [CuL](+) complexes could be correlated with the deprotonation constants of their hydroxyl group (log beta(LH)) reflecting that the higher acidity increases the complex stability in the order L2 < L1 approximate to L6 < L4 approximate to L5 < L3. This stability order elucidates the different axial linkers in the cyclic dimers 2 and 3. DFT quantum-chemical calculations support the effect of the electron distribution on the established stability order.},

	abstract = {In this study, relationships between preparation conditions, structure, and activity of Pt-containing TiO2 photocatalysts in photoinduced reforming of glycerol for H-2 production were explored. Commercial Aerolyst((R)) TiO2 (P25) and homemade TiO2 prepared by precipitation-aging method were used as semiconductors. Pt co-catalysts were prepared by incipient wetness impregnation from aqueous solution of Pt(NH3)(4)(NO3)(2) and activated by calcination, high temperature hydrogen, or nitrogen treatments. The chemico-physical and structural properties were evaluated by XRD, H-1 MAS NMR, ESR, XPS, TG-MS and TEM. The highest H-2 evolution rate was observed over P25 based samples and the H-2 treatment resulted in more active samples than the other co-catalyst formation methods. In all calcined samples, reduction of Pt occurred during the photocatalytic reaction. Platinum was more easily reducible in all of the P25 supported samples compared to those obtained from the more water-retentive homemade TiO2. This result was related to the negative effect of the adsorbed water content of the homemade TiO2 on Pt reduction and on particle growth during co-catalyst formation.},
