Degradable 2-Hydroxyethyl Methacrylate/Gelatin/Alginate Hydrogels Infused by Nanocolloidal Graphene Oxide as Promising Drug Delivery and Scaffolding Biomaterials
(Gels, 2022)
The design and evaluation of novel 2-hydroxyethyl methacrylate/gelatin/alginate/graphene oxide hydrogels as innovative scaffolding biomaterials, which concurrently are the suitable drug delivery carrier, was proposed. The ...
The physicochemical properties of the deep eutectic solvents with triethanolamine as a major component
(Srpsko hemijsko društvo, Beograd, 2020)
Different deep eutectic solvents (DESs) of triethanolamine (TEOA) and oxalic acid (OA), glacial acetic acid (AA), L-(+)-lactic acid (LA), oleic acid (OLA), glycerol (G), ethylene glycol (EG), propylene glycol (PEG), choline ...
Activated carbon materials derived from hemp fibers in pesticide adsorption and water disinfection / Adsorpcija pesticida i dezinfekcija vode aktiviranim ugljeničnim materijalima na bazi vlakana konoplje
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2015)
By varying the parameters of carbonization and activation, different samples of hemp fibers based activated carbon were obtained. Optimal production conditions were selected based on the adsorption properties of activated ...
Polyhydroxyalkanoate/Antifungal Polyene Formulations with Monomeric Hydroxyalkanoic Acids for Improved Antifungal Efficiency
(Antibiotics, 2021)
Novel biodegradable and biocompatible formulations of "old" but "gold" drugs such as nystatin (Nys) and amphotericin B (AmB) were made using a biopolymer as a matrix. Medium chain length polyhydroxyalkanoates (mcl-PHA) ...
The influence of thermodynamic parameters on alkaline activators of geopolymers and the structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 degrees C for the process of ...
Evaluation of stability and functionality of BaCe1-xInxO3-delta electrolyte in a wider range of indium concentration
(Journal of Advanced Ceramics, 2022)
The properties of BaCe1-xInxO3-delta (x = 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, and 0.40) as proton conducting electrolyte are examined. The dense electrolyte is formed after sintering at 1300 degrees C for 5 h in air. ...

Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The ...
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)
