Edible blend films of pectin and poly(ethylene glycol): Preparation and physico-chemical evaluation
(Elsevier Sci Ltd, Oxford, 2018)
The aim of this study was the development of novel polysaccharide based films intended to be used as edible food packaging material. The films were prepared by solution casting method using highly methoxylated pectin (PEC) ...
Honeybees as sentinels of lead pollution: Spatio-temporal variations and source appointment using stable isotopes and Kohonen self-organizing maps
(Elsevier, Amsterdam, 2018)
In this study, honeybees were used to determine spatio-temporal variations and origin sources of Pb. Lead concentrations and isotopic composition were used in combination with selected statistical methods. The sampling was ...
Synthesis of fluorapatite nanopowders by a surfactant-assisted microwave method under isothermal conditions
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
Fluorapatite nanopowders with different amounts of fluoride ions were prepared using the surfactant-assisted microwave method under isothermal conditions. Microwave irradiation was applied for the rapid formation of crystals. ...
Composite nanostructured hydroxyapatite/yttrium stabilized zirconia dental inserts - The processing and application as dentin substitutes
(Elsevier Sci Ltd, Oxford, 2018)
The objective of the study was to process nano-structured hydroxyapatite/yttrium-stabilized zirconia bioceramic and to investigate the possibilities of its application as dentin replacement in the form of dental inserts. ...
Statistical review of the insulation capacity of the geiger-mueller counter
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
This work considers the manifestation of spontaneous breakdowns of Geiger-Mueller counters. This is an experimental type of work. The reasons leading to the spontaneous breakdowns of Geiger-Mueller counters have been ...
CO2 conversion enhancement in a periodically operated Sabatier reactor: Nonlinear frequency response analysis and simulation- based Study
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Nonlinear frequency response (NFR) analysis was applied on a Sabatier reactor. A substantial improvement in CO2 conversion was predicted under certain conditions. The NFR analysis prediction was validated using a kinetic ...
Application of supercritical carbon dioxide in fabrication of materials with repellent properties based on pyrethrins / Primena natkritičnog ugljenik(IV)-oksida za dobijanje materijala sa repelentnim svojstvima na bazi piretrina
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2018)
This PhD thesis was aimed to investigate the possibility of supercritical solvent impregnation (SSI) of selected polymer materials (cotton fabric, polypropylene (PP) non-woven fabric, polyamide (PA) polymers (fabric, ...
Tomato pomace powder as a raw material for ketchup production
(Elsevier Science Bv, Amsterdam, 2018)
A value-added ketchup from tomato pomace powder was developed and compared to a previously developed ketchup from fresh tomato pomace. The total dietary fiber content of tomato pomace powder ketchup was higher than fresh ...
Cleaner and energy efficient production: a case study
(Gheorghe Asachi Technical University of Iasi, Romania, 2018)
A project called 'Cleaner Production' is conducted in the organization of the Cleaner Production Centre of Serbia at the Faculty of Technology and Metallurgy, University of Belgrade and the United Nations Industrial ...
Synthesis and characterization glycidyl azide polymer of an attractive binder for energetic materials / Sinteza i karakterizacija glicidil azid polimera atraktivnog veziva za energetske materijale
(Military Technical Institute, Belgrade, 2018)
The glycidyl azide polymer (GAP), known as an energetic, thermally stable, low sensitive, hydroxyl-terminated prepolymer, was synthesized using different diol and triol initiator units. GAP was prepared by azidation of ...
