Synthesis and characterization of new cerium doped phosphate tungsten bronze
(Society of Physical Chemists of Serbia, 2021)
Cerium doped phosphate tungsten bronze (Ce-PWB) was synthetized by phase transformations of CePW12O40x6H2O (Ce-6-PWA) salt. The solid-solid transformations of Keggin's anion of this salt, including dehydration processes ...
Chitosan nanoparticles functionalized viscose fabrics as potentially durable antibacterial medical textiles
(MDPI, 2021)
This research proposed two pretreatments of viscose fabrics: oxidation with 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) and coating with TEMPO-oxidized cellulose nanofibrils (TOCN), to introduce functional groups ...
Green pH- and magnetic-responsive hybrid hydrogels based on poly(methacrylic acid) and Eucalyptus wood nanocellulose for controlled release of ibuprofen
(Springer, 2021)
pH- and magnetic-sensitive hybrid hydrogels based on poly(methacrylic acid) (PMAA), nanocellulose (NC), carboxymethyl cellulose (CMC) and magnetite particles (MN) were prepared as ibuprofen delivery system. NC was isolated ...
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 ...
Copper removal by pelletized fly ash
(Belgrade, Serbia : University of Belgrade - Faculty of Mining and Geology, 2021)
The increasing levels of industrial wastewater that are released to the environment present a serious threat to human health, living resources, and ecological systems. Fly ash was tested for the removal of Cu2+ from ...
From raw starch degrading α-amylase to transglycosylase by single point mutation
(University of Belgrade, 2021)
Understanding the structural peculiarities and properties of both, raw starch as a substrate and raw starch digesting amylases (RSDA) as an enzymes is needed for efficient application in food and other industries. Although ...
Postupak solidifikacije i stabilizacije teških metala iz otpadnih rudničkih voda adsorbovanih na paletama letećeg pepela u ekološki prihvatljiv građevinski materijal / Procedure of solidification and stabilization of heavy metals from mine waste waters adsorbed on fly ash pellets into enviromentally acceptable building material
(Zavod za intelektualnu svojinu Republike Srbije, 2021)
Stabilizacija teških metala, posebno bakra, iz kiselih otpadnih rudničkih voda izvodi se njihovom solidifikacijom u sumpor polimerni beton kao ekološki prihvatljiv građevinski materijal. Postupak se izvodi tako što se u ...
Upoređivanje bioaktivnosti, citotoksičnosti, antimikrobnih i korozivnih svojstava keramičkih prevlaka sa i bez polimera na titanu / Comparison of bioactivity, cytotoxicity, antimicrobial and corrosive behavior of ceramic coatings with and without polymer on titanium
(Beograd : Udruženje inženjera Srbije za koroziju i zaštitu materijala UISKOZAM, 2021)
Kalcijum fosfati (CP), među kojima su amorfni kalcijum fosfat (ACP) i hidroksiapatit (HAp), zajedno sa slojevima Ti i TiO2, pronašli su ogromnu primenu u preventivnoj i regenerativnoj medicini zbog svoje odlične ...
