Ethanol Thymus serpyllum extracts: Evaluation of extraction conditions via total polyphenol content and radical scavenging activity
(Institute for Medicinal Plants Research "Dr. Josif Pancic", 2019)
The aim of the present study was the optimization of the extraction conditions (particle size, solid-to-solvent ratio, extraction time and procedure) via total polyphenol content and radical scavenging activity, using wild ...
Synthesis of novel wo3/zrsio4 catalysts for dehalogenation of halogenated hydrocarbons
(Savez inženjera metalurgije Srbije, Beograd, 2019)
This research aimed to develop a novel catalyst based on WO3/ZrSiO4 system for halogenated hydrocarbons processing. The production method of this catalyst involved extrusion and as such was simplified compared to thermo-chemical ...
Inventive level as a basis for the assessment of scientific contribution of inventors / Inventivni nivo pronalaska kao osnov za procenu naučnog doprinosa pronalazača
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
The history of invention reveals that the most important inventions were derived from experiments by which their authors contributed to the discovery of previously unknown natural phenomena. So the question arises as to ...
Characterisation of the nanotubular oxide layer formed on the ultrafine-grained titanium
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Commercially pure titanium (cpTi) and titanium alloys are metallic implant materials usually used in dentistry and orthopaedics. In order to improve implant properties, Ti-based materials may be surface modified by different ...
Characterization of tantalum coatings deposited using vacuum plasma spray process / Karakterizacija tantal prevlake deponovane vakuum plazma sprej procesom
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Tantalum is a very popular material for the industry as a whole because of very important characteristics such as: high melting point, significant thermal and electrical conductivity, high toughness and resistance to ...

ANTIOXIDANT and ANTIMICROBIAL CAPACITY of ENCAPSULATED THYME ESSENTIAL OIL in ALGINATE and SOY PROTEIN-BASED CARRIERS
(University of Novi Sad, Faculty of Technology, 2021)
The aim of this study was to develop a stable hydrogel carrier system for thyme essential oil (TEO) that could protect its sensitive polyphenol compounds. The impact of wall material (soy protein and alginate) on encapsulation ...
Optimizing the thermal gradient and the pulling speed in a thermoplastic pultrusion process of pet/e glass fibers using finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2018)
A thermoplastic pultrusion process was examined using commercial fiber roving of PET/E glass, to determine the optimum pulling speed and optimal zonal temperatures. Finite element analysis predicted heat transfer through ...
Nanotubular oxide layers formed on the ti-based implants surfaces-application and possible damages: a review
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Implant surface properties define the interaction of the implant with the surrounding tissue. To obtained advanced biological, mechanical and physical properties, metallic implants are often exposed to different kinds of ...
Optimization of galacto-oligosacharides synthesis using response surface methodology / Optimizacija sinteze galakto-oligosaharida pomoću metoda odzivnih površina
(Institute for Food Technology, Novi Sad, 2017)
Galacto-oligosaccharides (GOS) are important lactose-derived compounds, considered to be a prebiotics, based on abundant scientific evidence about their unique physical properties and physiological effects. This consequently ...
