Impregnation of cellulose acetate with natural bioactive compounds using supercritical carbon dioxide
(Book of abstracts - 7th International Congress of the European Polysaccharide Network of Excellence, 2021)
Porous acetate cellulose (CA) beads were tested as carriers for thymol, eugenol and
carvacrol, natural compounds well known for their biological activity. For this purpose,
selected compounds were impregnated into CA ...
Influence of sintering time on density properties and SEM analysis of cordierite-based ceramics / Uticaj vremena sinterovanja na gustinu i SEM analiza kordijeritne keramike
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
Electrical properties of isothermally sintered cordierite-based ceramics as function of sintering and activation time / Električna svojstva izotermski sinterovane keramike na bazi kordierita kao funkcija vremena sinterovanja i aktivacije
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)

Tailoring of MgO/Mg(OH)2 structures by molten salt electrolysis
(Beograd : Udruženje inženjera Srbije za koroziju i zaštitu materijala (UISKOZAM), 2022)
The magnesium oxide (MgO)/magnesium hydroxide (Mg(OH)2) nanostructures aside from showing high surface area, good thermal, electrical, optical and chemical characteristics, are also low-cost materials of benign nature with ...
Characterization of raw peach stones and its biochar by SEM, FTIR and Raman spectroscopy
(Association of Metallurgical Engineers of Serbia (AMES), 2023)
Growing industrialization and non-renewable resource depletion have a huge impact on alternative clean up technologies development, inducing investigation of the renewable, low-cost waste materials. Recently, lignocellulosic ...
The Morphological Characterization of Mechanically Activated ZnO Powder
(Belgrade : Serbian Ceramic Society, 2014)
The authors investigated the morphological characteristics of mechanically activated ZnO powder. ZnO powder was mechanically activated for 2, 5, 10 and 30 minutes in a planetary ball mill. Mechanical activation introduces ...
Influence of IR camera integration time on the accuracy of Tmax determination during laser interaction with ceramics
(Belgrade : Military Technical Institute, 2020)
This paper presents the results of an infrared thermography (IRT) application for monitoring temperature
distribution on a ceramic surface during Nd: YAG laser irradiation. The laser operated in the Q-switch ...
Polyethersulfone membranes with integrated adsorbent particles for heavy metals capture
(Belgrade, Serbia : Society of Physical Chemists of Serbia, 2014)
Novel polyethersulfone membranes with integrated submicron adsorbent particles were prepared by combining photoirradiation with liquid phase inversion. These particles consist of cross-linked poly(glycidyl methacrylate-c ...
The effect of poly(dimethylsiloxane) segment content on the morphology of polyurethane composite materials
(Belgrade : Serbian Academy of Sciences and ArtsBelgrade : Faculty of Technology and Metallurgy, University of Belgrade, 2022)
in this study, in situ polymerization procedure in solvent mixture was used for the preparation of thermosetting PU nanocomposites (PUNCs) with different content of soft segment (from 30 to 60 wt%), and with the addition ...
Some questions about morphology and structure of electrodeposited metal coatings
(The Society of Chemists and Technologists of Macedonia, 2008)
The relationship between the light-reflecting property generally referred to as the brightness, and structure of electrodeposits has been the subject of many investigations. These studies have led to two theories. One ...
