Theoretical modeling of sorption of metal ions on amino-functionalized macroporous copolymer in aqueous solution
(Springer, 2019)
With regard to the harmful effects of heavy metals on human health and the environment, the demand for synthesis and investigation of macromolecules with large capacity of harmful substances sorption is ever greater. ...
Alternating catalytic reactions
(Springer, 2019)
The application of alternating current is advantageous in energy transfer over long distances. It is a well-known fact now, but subject of long conflict in the era of pioneering works in electric power production. There ...
Seasonal Dynamics of Cyanobacteria and Algae in Biofilm from the Entrance of Two Caves
(Taylor & Francis, 2020)
Aerophytic phototrophs, colonizers of different substrates exposed to air, among which are rock substrates in cave habitats, are in general not sufficiently investigated and studied. From the ecological point of view, ...
Effects of different polymers and solvents on crystallization of the NaYF4:Yb/Er phase
(Springer, 2020)
Up-converting NaYF4:Yb,Er nanoparticles were obtained by polymer-assisted solvothermal synthesis using a common solution of hydrated RE nitrates in ethanol or ethylene glycol. It was shown that polymer choice (polyacrylic ...
A novel PGA/TiO2 nanocomposite prepared with poly(γ-glutamic acid) from the newly isolated Bacillus subtilis 17B strain / Нови ПГК/TiO2 нанокомпозит добијен од поли(γ -глутаминске киселине) из новоизолованог соја bacillus subtilis 17B
(Serbian Chemical Society, 2023)
Poly(γ-glutamic acid) (PGA), naturally produced by Bacillus species, is a biodegradable, non-toxic, biocompatible, and non-immunogenic negatively charged polymer. Due to its properties, it has found various applications ...
Comparison of non-destructive techniques and conventionally used spectrometric techniques for determination of elements in plant samples (coniferous leaves) / Поређење недеструктивних и конвенционално коришћених спектометријских техника за одређивање елемената у биљном материјалу (иглице четинара)
(Journal of the Serbian Chemical Society, 2022)
Conventionally used spectrometric techniques of inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma optical emission spectrometry (ICP-MS) usually involve time-consuming sample ...
Adsorption of nicotine from aqueous solutions on montmorillonite and acid – modified montmorillonite
(International Institute for the Science of Sintering, Beograd, 2019)
Montmorillonite (Mt) and acid modified montmorillonite (MtA) were tested as
nicotine adsorbents. The samples were characterized using FT-IR spectroscopy and low
temperature nitrogen physisorption. Nicotine adsorption was ...
Bray–Liebhafsky oscillatory reaction as the matrix system for the kinetic determination of microquantities of alizarin and purpurin
(Springer Nature Switzerland AG 2020, 2020)
Two hydroxyanthraquinones, alizarin and purpurin, that have been used throughout
history as a natural pigment, were extracted from roots of Rubia tinctorum from
Serbia. As substances with important chemical activities ...
Alkaline soda Lake Velika Rusanda (Serbia): the first insight into diatom diversity of this extreme saline lake
(Springer Nature Publishing AG, 2019)
Alkaline soda lakes are unique habitats found in specific geographic regions, usually with dry climate. The Carpathian Basin
is one of those regions very important for habitat and biodiversity conservation in Europe, with ...
Cyanobacterial and algal abundance and biomass in cave biofilms and relation to environmental and biofilm parameters
(University of South Florida Libraries, 2019)
Due to life in extreme environments, cyanobacteria and algae from cave biofilms that form at the entrances or deep inside the cave around artificial lights are of increasing interest to many scientists. It is well-known ...
