Biodegradation of cotton fabric impregnated with TiO2 nanoparticles
(Srpsko hemijsko društvo, Beograd, 2019)
Commercial P25 TiO2 nanoparticles are widely exploited as an efficient photocatalyst. In the textile domain, these nanoparticles are used for the production of self-cleaning, highly UV protective textiles, with an antimicrobial ...
Production of technology metals from waste electronics
(Institut za istrazivanja i projektovanja u privredi, 2019)
The rising criticality of technologically inevitably metals and the continuous growth of the waste electronics promote a scientific need for development of innovative recycling process, both efficient and selective. ...
Assessment of Leaching Characteristics of Solidified Products Containing Secondary Alkaline Lead Slag
(MDPI, Basel, 2019)
Reuse of waste is one of the main principles of sustainable development and circular economy. Secondary alkaline lead slag is a hazardous waste generated in the recycling process of lead-acid batteries that may be suitable ...
Recyclability of technology metals from E-waste: Case study of in and Ga recovery from magnetic fraction
(Association of Metallurgical Engineers of Serbia, 2019)
This study presents the results of the theoretical assessment and a preliminary experimental investigation of technology metals (TM) recovery from magnetic fraction obtained after mechanical treatment of waste printed ...
Electrophoretically deposited hydroxyapatite-based composite coatings loaded with silver and gentamicin as antibacterial agents
(Srpsko hemijsko društvo, Beograd, 2019)
Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)-based composite materials on titanium and titanium alloy surfaces. Owing ...
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 ...
Preparation and characterization of oxidized wheat starch with hydrogen peroxide as an environmentally friendly oxidant
(7th Conference of the Young Chemists of Serbia, 2019)
The starch oxidation involves oxidation of primary or secondary hydroxyl to carbonyl
or carboxyl groups, whereas the number of these groups indicates the level of oxidation.
Oxidized starch is used as surface sizing agent ...
Novel composite zinc-alginate hydrogels with activated charcoal aimed for potential applications in multifunctional primary wound dressings
(Savez hemijskih inženjera, Beograd, 2019)
Composites based on Zn-alginate hydrogels in the form of beads were produced by extrusion of a suspension containing 0.5 % w/w of alginate and 20 % w/w of activated charcoal (AC) with the intent to simultaneously release ...
Synthesis of Tribological WS2 Powder from WO3 Prepared by Ultrasonic Spray Pyrolysis (USP)
(MDPI, Basel, 2019)
This paper describes the synthesis of tungsten disulfide (WS2) powder by the sulfurization of tungsten trioxide (WO3) particles in the presence of additive potassium carbonate (K2CO3) in nitrogen (N-2) atmosphere, first ...
The influence of short thermal treatment on structure, morphology and optical properties of Er and Pr doped ceria pigments: Comparative study
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2019)
Potential non-toxic pink and red ceramic pigments based on CeO2 were successfully synthesized by self-propagating room temperature method and thermally treated at 600, 900 and 1200 degrees C for 15 min. The structure, ...
