AbstractThe idea of creating replacement for damaged or diseased tissue, which will mimic the physiological conditions and simultaneously promote regeneration by patients’ own cells, has been a major challenge in the biomedicine for more than a decade. Therefore, nanofibers are a promising solution to address these challenges. Nanofiber technology ...

AbstractThe results of experimental studies of the electroflotation extraction of sparingly soluble Al3+ compounds from aqueous solutions in the presence of surfactants of various nature and alkaline earth metal ions (Mg2+, Ca2+, Ba2+) are reported. It was found that the Mg2+, Ca2+, Ba2+ ions in a solution at a concentration of 0.5 g L–1 reduces th...

AbstractIn this article we report preparation, physico-chemical and mechanical characterization of poly (vinyl acetate) (PAVc) films resulting from the copolymerization of vinyl acetate (VAc) with two acrylate monomers, butyl acrylate (BuA) and 2‐ethyl hexyl acrylate (2-EHA) via emulsion polymerization method. Vinyl acetate (VAc) was used as princi...

AbstractStable selenium nanoparticles were synthesized in a sodium carboxymethylcellulose (Na-CMC) solution with a degree of substitution of 0.85 and an average molar weight of 250 000. The shape and size of selenium nanoparticles were determined by dynamic light scattering and UV spectroscopy. It was found that the nanoparticles coated with Na-CMC...

AbstractIn this work, CuO thin films were deposited by successive ionic layer adsorption and reaction (SILAR) method at room temperature. The synthesis parameters of the method were changed to examine the details of the production method. Our main goal was the optimization of the deposited CuO thin films in terms of their structural, optical and el...

AbstractIn this study, non-flammable insulator materials with high thermal resistance have been produced for vessel doors. Silica-based polymers were used as core materials. Four different synthesis routes are procured and their morphologies, thermal performances, and flammability properties are compared. Thermal properties of the synthesized silic...
