Preparation Co3O4 nano- and microparticles by solid state thermolysis of cobalt(II) complex
(Belgrade : Institute for Multidisciplinary Research, University, 2019)
Development of nanomaterials such as transition metal oxides with spinel
structure has been intensively examined because of their applications in catalysis,
energy storage, magnetic data storage and sensors [1]. Synthesis ...
Walsh analysis - a convenient preprocessor for period detection in astronomy
(Astronomical Observatory Belgrade, 2016)
Walsh analysis is practically analogous to Fourier analysis, except that square wave is used instead of the sine one. It has one major advantage over Fourier - it can be performed much faster. This may seem of little ...
Effect of different reaction parameters on lipase-catalyzed esterification of naringin and esculin
(Faculty of Technology, University of Banja Luka, 2018)
Fatty acid flavonoid esters are antioxidants with high potential for food, cosmetic and pharmaceutic industry. However, their application is still not wide-spread due to low efficiency of traditional chemical esterifications, ...
Određivanje veštačkog zaslađivača saharina u uzorcima otpadne vode / Determination of artificial sweetener saccharin in wastewater samples
(Beograd : Beogradska politehnika, 2019)
Široka primena veštačkih zaslađivača u prehrambenoj i farmaceutskoj industriji počela je početkom osamdesetih godina prošlog veka. Većina ovih jedinjenja se ne metaboliše u ljudskom telu i izlučuje se uglavnom nepromenjena. ...
The effects of aging on the precipitation of the W-rich phase in the matrix of the 92.5W-5Ni-2,5Fe powder metallurgy heavy alloys
(Association of Metallurgical Engineers of Serbia (AMES), Beograd, 2013)
The precipitation behavior of W-rich phase on the specific matrix locations of
Co-free and Co-containing 92.5W-5Ni-2.5Fe heavy alloys is investigated during
aging of the as-quenched samples. The aging treatment is ...
Adsorpcija estrogenih hormona iz vodenih rastvora na različitim ugljeničnim materijalima
(Beogradska politehnika, 2019)
U ovom radu vršena je adsorpcija estrogenih hormona (estrona, 17β-estradiola i
17α-etinilestradiola) na različitim ugljeničnim materijalima, u cilju ispitivanja primenljivosti ovih
materijala za uklanjanje estrogenih ...
The analysis of stability of the electrospinning process of forming PVB-SiO2 nanocomposite fibers
(Belgrade : Materials Research Society of Serbia, 2011)
The PVB-SiO2 composite nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt% where as the solvent was used ethanol. The silica nanoparticles ...
PREPARATION, CHARACTERIZATION AND ANTIBACTERIAL ACTIVITY OF CLINOPTILOLITE/THYMOL COMPOSITES
(Srpsko zeolitsko drustvo, Beograd, 2019)
Composites based on natural zeolite – clinoptilolite and thymol were prepared using
two different approaches: 1) wet impregnation (WI) and supercritical solvent impregnation
(SSI). The SSI was more superior since it ...
In situ synthesis of Cu/Cu2O nanoparticles on the TEMPO oxidized cotton fabric / In situ sinteza Cu/Cu2O nanočestica na TEMPO oksidovanoj pamučnoj tkanini
(Beograd : Serbian Chemical Society, 2017)
Recent breakthrough in nanotechnologies had large impact on research in the field of medical textiles. So far many efforts have been made to fabricate antimicrobial textile materials with incorporated metal (Ag, Cu) and ...
Antifungalna aktivnost etarskih ulja mediteranskih biljaka prema Candida albicans
(Društvo medicinskih mikrobiologa Srbije - DMMS, 2016)
Upotreba antibiotika širokog spektra dejstva, kortikosteroida, imunosupresiva, kao i brojni spoljni faktori koji slabe odbrambene funkcije organizma, intenziviraju rast Candida albicans i uzrokuju pojavu kandidijaze. Ova ...
