AB  - Composite systems of monolayer and multilayer nickel films electrochemically deposited on single crystal (100)-oriented silicon wafers were fabricated with and without the ultrasonic agitation. The hardness and adhesion behaviour of these composite structures were characterized by Vickers microindentation test. The dependence of composite microhardness and film adhesion on the structure of the film and mixing conditions of electrolyte were analysed. Mathematical models of Chicot-Lesage and Chen-Gao were applied to experimental data in order to obtain the film hardness and adhesion parameter respectively. It is confirmed that the mechanical properties of composite systems of nickel thin films on silicon substrate can be enhanced by formation of multilayer film structure by ultrasound-assisted electro-deposition and by reducing the layer thickness in the multilayer film.
AB  - Formirani su kompozitni sistemi od jednoslojnih i višeslojnih filmova nikla elektrohemijski deponovanih sa i bez ultrazvučnog mešanja na pločicama od monokristalnog silicijuma orijentacije (100). Tvrdoća i adhezija tih kompozitnih struktura su okarakterisane testom mikrotvrdoće po Vikersu. Analizirana je zavisnost mikrotvrdoće kompozita i adhezije filma od strukture filma i uslova mešanja elektrolita. Matematički modeli Šiko-Lezaža i Čen-Gaoa su primenjeni na eksperimentalne podatke kako bi se dobile vrednosti tvrdoće filma i parametra adhezije. Potvrđeno je da se mehanička svojstva kompozitnih sistema sastavljenih od tankih filmova nikla na silicijumskoj podlozi mogu poboljšati formiranjem višeslojne strukture filmova, primenom ultrazvučnog mešanja pri elektrodepoziciji i smanjenjem debljine sloja u višeslojnom filmu.

AB  - In the context of the macroscopic quantum phenomena of the second kind, we hereby seek for a solution-in-principle of the long standing problem of the polymer folding, which was considered by Levinthal as (semi)classically intractable. To illuminate it, we applied quantum-chemical and quantum decoherence approaches to conformational transitions. Our analyses imply the existence of novel macroscopic quantum biomolecular phenomena, with biomolecular chain folding in an open environment considered as a subtle interplay between energy and conformation eigenstates of this biomolecule, governed by quantum-chemical and quantum decoherence laws. On the other hand, within an open biological cell, a system of all identical (noninteracting and dynamically noncoupled) biomolecular proteins might be considered as corresponding spatial quantum ensemble of these identical biomolecular processors, providing spatially distributed quantum solution to a single corresponding biomolecular chain folding, whose density of conformational states might be represented as Hopfield-like quantum-holographic associative neural network too (providing an equivalent global quantum-informational alternative to standard molecular-biology local biochemical approach in biomolecules and cells and higher hierarchical levels of organism, as well).
