On macroscopic quantum phenomena in biomolecules and cells: From levinthal to hopfield
(Hindawi Publishing Corporation, 2014)
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 ...
Mechanical properties of composites based on unsaturated polyester resins obtained by chemical recycling of poly(ethylene terephthalate) / Mehanička svojstva kompozita na bazi nezasićenih poliestarskih smola dobijenih hemijskom reciklažom poli(etilen-tereftalata)
(Association of Chemical Engineers of Serbia, 2013)
Composites based on unsaturated polyester (UPe) resins and fumed silica AEROSIL® RY 50, NY 50, RX 50 and NAX 50, as well as graphite, TiO2 or organically modified clay CLOISITE 30B were prepared in order to investigate the ...
Mechanical and magnetic properties of composite materials with polymer matrix
(Technical Faculty, Bor, 2010)
Many of modern technologies require materials with unusual combinations of properties that cannot be met by the conventional metal alloys, ceramics, and polymeric materials. Material property combinations and ranges have ...
Quality attributes of a fermented whey-based beverage enriched with milk and a probiotic strain
(Royal Society of Chemistry, 2014)
Beverages produced by fermentation of whey have significantly lower viscosity, milder flavour and less viability of probiotic microorganisms compared to those obtained by fermentation of milk. Therefore, it is necessary ...

Influence of annealing treatment on magnetic properties of Fe2O3/SiO2 and formation of epsilon-Fe2O3 phase
(Ceramics International, 2017)
Magnetic properties of Fe2O3/SiO2 samples were studied after being produced by sol-gel synthesis and formation of epsilon-Fe2O3 polymorph. Samples were thermally treated, using different annealing temperatures and annealing ...
Technological possibilities and justification of electro-contact rapairing
(Technics Technologies Education Management, 2011)
This paper presents a selected repair technology for different types of electro-contacts by replacing the contact plates on the brass body of the electro-contacts and connecting the elements by process of brazing with ...
RuxTi1-xO2 as the support for Pt nanoparticles: Electrocatalysis of methanol oxidation
(Elsevier, Amsterdam, 2015)
Two binary Ru-Ti oxides, Rum Ti0.9O2 and Ru0.7Ti0.3O2, were synthesized by the sol-gel method and used as an electrocatalyst support. The system was characterized by XRD, EDS, TEM and cyclic voltammetry. The Rum Ti0.9O2 ...
Modification of chitosan by zeolite A and adsorption of Bezactive Orange 16 from aqueous solution
(Composites: Part B: Engineering, 2013)
This study represents new material based on chitosan modified by zeolite A as adsorbent for anionic dye, using Bezactive Orange 16 as a model compound. Interactions between dye and chitosan/zeolite A film at initial ...
