Synthesis and properties of nano-hydroxyapatite/poly (methacrylic acid) composite hydrogels / Uticaj neutralizacije na svojstva poroznih hidrogelova na bazi hidroksiapatita i poli(metakrilne kiseline) sintetisanih slobodno-radikalskom polimerizacijom
(Beograd : Savez inženjera i tehničara Srbije, 2018)
Goals. The goal of this study was a development of biocompatible composite hydrogels, structurally similar to native bone tissue, by incorporation of ~60 wt % of calcium hydroxyapatite (HA) into a matrix of hydrogels. Also, ...
A Strategy to Revalue a Wood Waste for Simultaneous Cadmium Removal and Wastewater Disinfection
(Hindawi Limited, 2021)
In this investigation, the possibility of wood waste (hardwoods such as oaks' and alternatives' staves from Balkan cooperage) revalorization for simultaneous cadmium removal and wastewater disinfection was examined. All ...
High performance alkyd resins synthesized from postconsumer PET bottles
(The Royal Society of Chemistry, 2015)
The glycolytic recycling of waste PET presents a challenge for the production of secondary value-added products, such as alkyd resins. A way to overcome the unsatisfactory mechanical, drying and chemical resistance properties ...
The influence of the size and surface modification of TIO2 nanoparticles on the rheological properties of alkyd resin / Uticaj veličine nanočestica TIO2 i njihove površinske modifikacije na reološka svojstva alkidne smole
(Association of Chemical Engineers of Serbia, 2013)
Spherical TiO2 particles of different size were dispersed in alkyd resin based on soybean oil. Four samples of TiO2 particles were used, three commercial and one obtained by acid catalyzed hydrolysis of titanium ...
Growth temperature of different local isolates of bacillus sp in the solid state affects production of raw starch digesting amylases
(Inst Bioloska Istrazivanja Sinisa Stankovic, Beograd, 2014)
Natural amylase producers, wild type strains of Bacillus sp., were isolated from different regions of Serbia. Strains with the highest amylase activity based on the starch-agar plate test were grown on solid-state fermentation ...
Electrochemical oxidation of 2,4,6-trichlorophenol on iron-doped nanozirconia cerami / Elektrohemijska oksidacija 2,4,6-trihlorfenola na nano-cirkonijum - oksidnoj matrici dopiranoj gvožđem
(Beograd: Srpsko hemijsko društvo, 2021)
Solvothermaly synthesized zirconium oxide nanopowders, pure and
doped with various amounts of iron ions (1–20 %), were used as modifiers of
glassy carbon electrodes. The modified electrodes were tested in the reaction ...
Application of Zirconia/Alumina composite oxide ceramics as photocatalysts for removal of 2,4,6-trichlorophenol from water
(MDPI, 2022)
The mesoporous zirconia/alumina composites were synthesized via a sol–gel method,
followed by heat treatment at 500 ◦C for 5 h. The effect of the ZrO2/Al2O3 ratio on the structural and
textural properties of the obtained ...
A possible connection between phosphate tungsten bronzes properties and briggs-rauscher oscillatory reaction response
(Belgrade : International Institute for the Science of Sintering (IISS), 2021)
The calcium phosphate tungsten bronze (Ca-PWB) has been synthesized and characterized (TGA, DSC, XRPD, FTIR, SEM). The influence of solid insoluble materials Ca-PWB, as well as lithium doped (Li-PWB) and cation free phosphate ...
Application of Ni(II)-alumina Composites for Electrocatalytic Reduction of 4-nitrophenol
(International Institute for the Science of Sintering, Belgrade, 2020)
Nickel-alumina composites with various content of nickel were synthetized by sol-gel method. The characterization of samples was performed by diffuse reflectance spectroscopy and electrochemical impedance spectroscopy using ...
