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 ...
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 ...
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 ...
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 ...
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 ...
Recasting as a booster of Ag-Pd alloy cytotoxicity: induction of cell senescence prior to mass cell death
(Serbian Biological Society, 2019)
The biological quality and chemical composition of alloys used in dental practice change during heat treatment.
Often the residues of the previous cast are not disposed of but are reused and recycled until consumed. Thus, ...
Equilibrium fluctuations in chemical reactions: a viable source of random data (numbers, maps and sequences)
(Springer Nature, 2021)
Random sequences and maps are essential for the applications in cryptography and many other fields in Information Technologies. To achieve true randomness, one still needs to refer to natural phenomena, be it physical, ...
Investigation of the Antioxidant Role of Acidic and Alkaline Hydrolysates of Pectin Isolated from Quince (Cydonia oblonga)
(Springer, 2022)
In this research, the antioxidant activity of acidic and alkaline hydrolyzates of pectin isolated from quince (Cydonia oblonga) was investigated. The antioxidant role of quince has been known since before, but so far few ...
Mass transfer in inverse fluidized beds / Пренос масе у инверзно флуидизованом слоју
(Serbian Chemical Society, 2023)
In this work, the coefficient of fluid-wall mass transfer in an inverse fluidized bed was determined using the adsorption method. The experiments were carried out in a column with a diameter of 45 mm with spherical and ...
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 ...
