Uticaj anjonskog i nejonskog tenzida na fizičko-hemijske osobine vodenih rastvora makromolekula [PDF]

open access: yes, 2016
The possible interactions between polymers and surfactants are of great interest in the development of drug delivery systems, where they improve therapeutic efficiency by the controlled release and reduced toxicity. The addition of even a small amount of surfactant could change the physico-chemical properties of polymer dispersions in terms of ...

Uticaj sorte na prorodevanje, rast stabla, prinos i fizičko-hemijske osobine ploda kajsije

open access: yes, 2012
Tokom tri godine (2008-2010) ispitivano je prorodevanje, bujnost stabla, osobine prinosa i najznačajnije fizičko-hemijske osobine ploda pet sorti kajsije kalemljenih na džanarici i gajenih na plitkom, peskovitom i kiselom zemljištu u okolini Čačka. Sorta per se (genotip) je pokazala snažan uticaj na rast stabla, prinos, krupnoću i čvrstinu ploda i ...

Fizičko-hemijske i katalitičke osobine ugljeničnih nanocevi sintetisanih metodom katalitičke hemijske depozicije iz gasne faze – korelacija sa osobinama primenjenih katalizatora na bazi prelaznih metala (Fe, Co, Ni) [PDF]

open access: yes, 2014
The existance of carbon nanotubes (CNTs), as one of the carbon allotropes, was noted over half century ago. However, the true interest for these nanomaterials appeared at 1991, when they were "redescovered" by Japanese scientist S. Iijima. Since then, due to their unique physico-chemical properties, CNTs begin to attract attention of the scientific ...
