Durability of alkali activated slag in a marine environment: Influence of alkali ion
(Srpsko hemijsko društvo, Beograd, 2018)
The durability of alkali-activated steel electric arc furnace slag (EAFS) in a marine environment was evaluated with respect to the chemical composition of the alkaline activator. Two different alkaline activators have ...
Ad-hoc intercomparison of four different radon exhalation measurement methods
(Oxford Univ Press, Oxford, 2018)
It is indicated that the exposure to radon originating from the building materials is not negligible and the radon exhalation measurement should get more attention in the future. The experience with four different methods ...
Statistical review of the insulation capacity of the geiger-mueller counter
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
This work considers the manifestation of spontaneous breakdowns of Geiger-Mueller counters. This is an experimental type of work. The reasons leading to the spontaneous breakdowns of Geiger-Mueller counters have been ...
Innovative environmentally friendly technology for copper(II) hydroxide production
(Savez hemijskih inženjera, Beograd, 2018)
The innovative laboratory procedure for the synthesis of copper(II) hydroxide in the form of the aqueous suspension was developed. The reaction mechanism consists of the reaction between copper(II) sulphate pentahydrate ...
Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, New York, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
Development and validation of a stability-indicating LC-UV and LC-MS/MS methods for quantitative analysis of anisomycin and identification of degradation products
(University of Sao Paulo, Conjunto Quimicas, Sao Paulo, 2018)
Multifunctional drug anisomycin was subjected to forced degradation in accordance with International Conference on Harmonisation (ICH) guidelines for the first time. The drug was exposed to the recommended stress conditions ...
In vivo investigation of soft tissue response of novel silver/poly(vinyl alcohol)/ graphene and silver/poly(vinyl alcohol)/chitosan/graphene hydrogels aimed for medical applications - the first experience
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2018)
In this paper, we have shown for the first time the soft tissue response of novel silver/poly(vinyl alcohol)/graphene (Ag/PVA/Gr) and silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels ...
Degradation of nicosulfuron using fenton and fenton-like reactions
(Savez hemijskih inženjera, Beograd, 2018)
Nicosulfuron, a sulfonylurea herbicide, was subjected to different Fenton reactions at pH of a nicosulfuron aqueous solution (pH 5). Usually, the optimal pH for the Fenton reaction is between 3 and 4, but the addition of ...
Removal of textile dyes from water by TiO2 nanoparticles immobilized on poly(ε-caprolactone) beads and foams
(Serbian Chemical Society, Belgrade, 2018)
This study discusses the possibility of immobilization of colloidal TiO2 nanoparticles (NPs) onto poly(ε-caprolactone) (PCL) beads and foams that could be utilized for the removal of textile dyes from water by photodegradation. ...
Influence of surface modification to mechanical and thermal properties of nanomodified acrylic dental resin
(Inst Materials Physics, Bucharest, 2018)
This paper investigated the processing and characterization of dental nanocomposites based on poly(methyl methacrylate) (PMMA) matrix reinforced with zirconium dioxide (ZrO2) nanoparticles were prepared by in-situ free ...
