Validation of a novel perfusion bioreactor system in cancer research
(Savez hemijskih inženjera, Beograd, 2020)
Development of drugs is a complex, time- and cost-consuming process due to the lack of standardized and reliable characterization techniques and models. Traditionally, drug screening is based on in vitro analysis using ...
Metal-loaded zeolite remediation of soils contaminated with pandrug-resistant Acinetobacter baumannii
(Inst Medical Research & Occupational Health, Zagreb, 2020)
Due to the development of resistance to antimicrobial agents, bacterium Acinetobacter baumannii is nowadays a leading cause of nosocomial outbreaks. Clinically relevant A. baumannii outside hospital settings including ...
Production of sub-micro sized silver particles by chemical reduction method in an environmentally-friendly manner
(Savez inženjera metalurgije Srbije, Beograd, 2020)
Silver nitrate in the solution was reduced in the presence of the dispersants by ascorbic acid, and silver particles were generated. The main goal was to examine the influence of different dispersants. The purpose was to ...
Influence of the precursor chemical composition on heavy metal adsorption properties of hemp (Cannabis Sativa) fibers based biocarbon
(Srpsko hemijsko društvo, Beograd, 2017)
Waste hemp (Cannabis sativa) fibers were used as sustainable and renewable raw materials for production of low-cost biocarbon sorbent for heavy metals removal. Carbon precursors of different chemical composition were ...
Estimation of GHG emission in Serbia for period 1995-2013 using recurent neural networks / Emisije gasova staklene bašte u Srbiji za period 1995-2013. godina primenom rekurentnih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The aim of this work was to create an ANN model for the prediction of GHG emissions in the Republic of Serbia in the period 1995-2013. Because of the lack of GHG emission data and inputs for Serbia, the ANN model was ...
Neke metode i uređaji za ispitivanje jednocikličnih i višecikličnih karakteristika tekstilnih materijala pri dejstvu aksijalnih sila / Some methods and devices for investigation of textile materials behavior under occurring once and repeated action of external axial forces
(Savez inženjera i tehničara tekstilaca Srbije, 2002)
Razmatrane su neke metode i uređaji za ispitivanje ponašanja tekstilnih materijala pri jednostrukom i višestrukom dejstvu spoljašnjih aksijalnih sila čiji je intenzitet manji od prekidnog. U radu su prikazani različiti ...
Synthesis of nanocrystalline nickel-ferrite in supercritical conditions and with use of starch microemulsion. / Sinteza nanaokristalnog nikl-ferita u natkritičnim uslovima i primenom skrobne mikroemulzije
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
Primary goal of the investigation carried out within this doctoral thesis was to assess the possibility to synthesize nano-crystalline powder of nickel-ferrite using novel reaction routes based on cheap and easily available ...
Application of Supercritical Solvent Impregnation for Production of Zeolite Modified Starch-Chitosan Polymers with Antibacterial Properties
(MDPI, Basel, 2020)
In the present study, supercritical solvent impregnation (SSI) has been applied to incorporate thymol into bio-composite polymers as a potential active packaging material. Thymol, a natural component with a proven antimicrobial ...
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 ...
Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
(Savez hemijskih inženjera, Beograd, 2020)
The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic ...
