Age hardening potential of an Al-4.6 wt.% Mg alloy with Cu addition
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The ageing behavior of an Al-4.6Mg-0.54Cu (in wt.%) alloy was studied after: (i) solution
treatment for 1h at 530°C, and (ii) annealing at 280°C for 3h. Both groups of the heat treated
specimens underwent further ...
DIELECTRIC LOSS TANGENT OF ALKALI TREATED JUTE WOVEN FABRICS: EFFECT OF HEMICELLULOSES CONTENT / TANGENS DIELEKTRIČNIH GUBITAKA ALKALNO TRETIRANIH TKANINA OD JUTE: EFEKAT SADRŽAJA HEMICELULOZA
(Belgrade : Union of Engineers and Technicians of Serbia, 2019)
The jute woven fabric was treated with sodium hydroxide at room
temperature for 5, 30 and 45 min in order to obtain jute fabric with different
hemicelluloses content and to study their influence on the dielectric loss ...
Nanocomposite Hydrogels Based on Poly(vinyl alcohol) and Chitosan with Silver Nanoparticles and Graphene Aimed for Wound Dressing Applications
(Belgrade : Serbian Academy of Sciences and Arts, 2018)
In this work, we prepared hydrogels based on PVA, CHI and Gr, and used them
as a porous matrix to synthesize silver nanoparticles by an in situ electrochemical
method [3,4]. The hydrogels were prepared from PVA/CHI/Gr ...
The influence of DBD plasma treatment on the dielectric loss tangent and surface morphology of fibrous polymeric materials
(Belgrade : Serbian Ceramic Society, 2019)
The aim of this work was to investigate the influence of dielectric barrier discharge (DBD) plasma
treatment during 30 and 60 seconds on the fibrous polymeric materials made of cotton, polyethylene terephthalate and ...

(Beograd : Srpsko kristalografsko društvo, 2015)
U proteklih nekoliko godina intenzivno se ispituje ideja o heterometalnim
koordinacionim jedinjenjima, zbog mogućnosti da se uvođenjem različitih prelaznih metala
poboljšaju katalitička, magnetna, fotoluminiscentna i ...
Antimikrobna aktivnost bagremovog meda / The antimicrobial activity of the acacia honey
(Leskovac : Tehnološki fakultet = Faculty of Technology, 2015)
Antibacterial, antifungal and antiviral activity of honey has been known since ancient times and mostly is connected with hydrogen peroxide, produced by the activity of the enzyme glucose oxidase, secreted by honeybees. ...
CORROSION BEHAVIOUR OF AN Al-Zn-Mg-Cu ALLOY AFTER DIFFERENT HEAT TREATMENTS
(Technical faculty Mihajlo Pupin, Zrenjanin, University of Novi Sad, Srbija, 2012)
The variation of factors such as the amount of alloying elements in solid solution, thermal and
thermo-mechanical treatments changes the corrosion tendency in the Al-Zn-Mg-Cu alloy. The measurements of
electrical ...
