This study examines the mineral composition of the extracts of the fruits, leaves and roots of white mulberry (Morus alba L.) and black mulberry (Morus nigra L.) grown in Serbia. All extract samples of white and black mulberry were analyzed for the content of micro (B, Co, Cr, Cu, Fe, Li, Mn, Ni, Se, Sr, Zn), macro (Ca, Mg, Na), and toxic metals (Al, As, Cd, Hg, Pb) by inductively coupled plasma optical emission spectrometry (ICP-OES). The study revealed that parts of the plant had statistically significant impact on the levels of the examined elements among the two Morus species. All extracts contained high amounts of Ca, Mg, Na, B, Cu, Fe, Mn and Zn. The studies showed that in the most of extracts dominant macro element was Mg (591- 1942 ?g/g of dry extract), while dominant microelements were Zn, B, Cu in all extracts, except for the black mulberry leaves, whose extract was most abundant in Fe (143 ?g/g of dry extract). The highest content of micro and macro elements was detected in the extract of black mulberry leaves. This work contributes to the knowledge of the nutritional properties of Morus species. The obtained results may be useful in the evaluation of new dietary and food products.

The present work has been undertaken to assess the evolution of dissolution process of large dendritic precipitates in a V-Nb-Ti microalloyed steel. The study was performed by reheating the samples at 1250°C, simulating the industrial reheating practices at laboratory scale and in situ, following industrial profile; afterwards the samples were quenched in 10%NaCl aqueous solution. The characterization of the material was carried out by scanning electron microscopy accompanied with dispersive energy spectrometry, and chemical analysis by inductively coupled plasma optical emission spectrometry. The results showed a partial dissolution of dendritic precipitates. This process ocurred by a progressive dissolving the Nb-rich shells formed over cuboidal particles and primary arm of well-faceted dendritic precipitates, and by fragmentation and spheroidization of secondary branches. These processes gave rise to spherical Nb rich precipitates and cuboidal particles at the reheating conditions used in this study. Both type of particles contain vanadium.

A novel Cu(II) complex 1 of 2-methoxy-5-sulfamoylbenzoic acid (Hsba) and eight novel mixed-ligand Cu(II) complexes 2–9 have been prepared using Hsba and 2-aminopyridine derivatives [2,3-diaminopyridine (2,3dap), 2,3-diamino-5-bromopyridine (2,3da5Brp), 2,3-diamino-5-chloropyridine (2,3da5Clp), 2-amino-3-benzyloxypyridine (2a3bxp), 2-amino-3-hydroxypyridine (2a3OHp), 2-amino-3-methylpiridine (2a3mp), 2-amino-3-methyl-6-ethylpiridine (2a3m6Etp) and 2-amino-3-nitro-6-methylpiridine (2a3NO26mp)], respectively. The structures of the amorphous metal complexes have been proposed by evaluating the data obtained from elemental analysis, inductively coupled plasma optical emission spectrometry (ICP-OES), Fourier-transform infrared spectroscopy (FTIR), ultraviolet–visible spectroscopy (UV–Vis), magnetic susceptibility and molar conductivity methods.
