Supercritical extraction of essential oil from Mentha and mathematical modelling- the influence of plant particle size
(Elsevier Science Bv, Amsterdam, 2012)
Supercritical CO2 extraction was studied using dried leaves of Mentha, originated from the northern part of Libya. Leaves were milled and sieved to obtain different average particles (d(p) = 0.25 - 0.80 mm). They were ...
Modeling and Prediction of the end of Life Vehicles Number Distribution in Serbia
(Budapest Tech, Budapest, 2016)
The impact of various time-defendant factors on the recycling rate of end-of-life vehicles (ELV) in Republic of Serbia was investigated. Statistical distribution of the frequency of the number of ELV in the year of dismantling ...
Complex sulphide-barite ore leaching in ferric chloride solution
(Association of Metallurgical Engineers of Serbia, 2016)
The results of research on the leaching process of complex sulphide-barite ore were presented in this paper. The leaching process was carried out in a laboratory autoclave by ferric chloride solution. Considering that those ...
Supercritical CO2 - assisted production of PLA and PLGA foams for controlled thymol release
(Elsevier Science Bv, Amsterdam, 2019)
Amorphous, medical grade poly(D,L-lactic acid) (PLA) and poly(D,L-lactic-co-glycolic acid) (PLGA) were used to develop systems for controlled release of a natural bioactive substance - thymol. Supercritical carbon dioxide ...
Functionalization of polypropylene, polyamide and cellulose acetate materials with pyrethrum extract as a natural repellent in supercritical carbon dioxide
(Elsevier Science Bv, Amsterdam, 2018)
This study discusses the possibility of supercritical solvent impregnation of polypropylene and polyamide fabrics as well as cellulose acetate in the form of beads and films with pyrethrum extract in order to fabricate ...
Development of polycaprolactone scaffold with antibacterial activity by an integrated supercritical extraction and impregnation process
(Elsevier, 2013)
The present study is aimed to develop a process for production of functionalized scaffolds impregnated with natural compounds extracted from Patagonian Usnea lichen. A setup for an integrated supercritical CO2 extraction ...
Development of material with strong antimicrobial activity by high pressure CO2 impregnation of polyamide nanofibers with thymol
(Elsevier Sci Ltd, Oxford, 2018)
This study discusses the potential of high pressure (supercritical and liquid) CO2 impregnation to load electrospun polyamide nanofibers with thymol as an antimicrobial agent. The influence of selected pressures and ...
Floating Photocatalyst Based on Poly(epsilon-caprolactone) Foam and TiO2 Nanoparticles for Removal of Textile Dyes
(Korean Fiber Soc, Seoul, 2018)
This study discusses a novel approach for fabrication of floating photocatalyst which can be efficiently exploited for photodegradation of dyes in aqueous solutions. A fabrication of the floating photocatalyst consisted ...
The shape of the polarization curve and diagnostic criteria for control of the metal electrodeposition process
(Serbian Chemical Society, 2016)
The simulated shapes of the polarization curves were correlated with the type of metal electrodeposition process control as a function of the ratio of the exchange current density to the limiting diffusion current density ...
Influence of different pre-treatment methods on isolation of extracts with strong antibacterial activity from lichen Usnea barbata using carbon dioxide as a solvent
(Elsevier, Amsterdam, 2013)
Multiplication and spreading of multiresistant pathogenic bacteria that cause fatal infections in humans and animals have boosted research on implementation of newer technologies for producing natural substances with strong ...
