The Dinuclear Cu (II) complex [{CuCl}2(μ – tppz)](PF6)2, where tppz represents tetra-2-pyridinylpyrazine, has been prepared and characterized by elemental analysis, 1H-NMR, IR and UV-vis spectroscopies. A crystal structure of the complex showed the Cu (II) are surrounded by three N atoms of tppz bridging ligand and one Cl atom. Crystal structure data are as follows: crystal system monoclinic, s...

     The fabrication of complex-shaped parts out of (wt %) Co-28Cr-6Mo alloy by three-dimensional printing (3DP) was studied using two grades of the alloy with average particle sizes of 20 and 75 μm. To produce sound specimens, 3DP processing parameters were tuned. The sintering behavior of the powders was characterized by the dilatometric analysis. Batch sintering in argon atmosphere at 1280 °...

The article focuses on the factors that cause linear and vertical sentence extension of multiple complex-compound sentences used in English fictional literature. Considering the sentence structure as a combination of 2 Units – paratactic and hypotactic the authors define the structural peculiarities of paratactic and hypotactic units including the number of clauses and its bonds. The extension ...
