Proučavanje uticaja metalnih vlakana na neka svojstva tehničkih pređa / Investigation of influence of metallic fibers on some properties of technical yarns
(Savez hemičara i tehnologa Srbije, 2000)
Ispitivana su neka mehanička i elektrofizička svojstva pređa formiranih od mešavine pamučnih i metalnih vlakana. Rezultati su upoređeni sa rezultatima dobijenim za pamučne pređe iste finoće. Registrovano je smanjenje ...
The Influence of Low-temperature Plasma Treatment on Wool Drying
(Institute of Phusics : Faculty of Physics : Institute of Nuclear Sciences "Vinča", Belgrade, 2000)
Morphologies of electrochemically formed copper powder particles and their dependence on the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Copper powder particles formed by electrolysis under different quantities of evolved hydrogen were analyzed using the scanning electron microscopy (SEM) technique. It was found that the structure of the powder particles ...
Hydrophobization of Cotton Fabrics with Fluorocarbon Plasmas
