Fabrication and Characterization of Thin Metal Films Deposited by Electroless Plating with Organic Additives for Electrical Circuits Applications.

In our work, we studied thin nickel films deposited by electroless plating for use as a barrier and seed layer in the through-silicon vias (TSV) technology. El-Ni coatings were deposited on a copper substrate from the original electrolyte and with the use of various concentrations of organic additives in the composition of the electrolyte. The surface morphology, crystal state, and phase composition of the deposited coatings were studied by SEM, AFM, and XRD methods.

Analysis of the spectral-luminescence properties of imidazo[1,2-b]pyrido[4,3-e][1,2,4]triazin-6(7Н)-ones.

The article presents a method for the construction of a new tricyclic system of imidazo[1,2-b]pyrido[4,3-e][1,2,4]triazin-6(7Н)-ones based on subsequent reactions of the obtained 1,2-diamino-4-phenylimidazole ethyl ether of 3-methyl-6-phenylimidazo[1,2-b][1,2,4]triazin-2-carboxylic acid with dimethylformamide dimethyl acetal and primary amines. The structures of the obtained compounds were confirmed using the data obtained from Н and С NMR, HRMS, and XRD analyses. We analyzed the dependence of the absorption and photoluminescence spectra on the structure of the compounds obtained using quantum chemistry methods.
