Characterization of glycidyl methacrylate based magnetic nanocomposites
(ASSOC CHEMICAL ENGINEERS SERBIA, 2019)
Magnetic and non-magnetic macroporous crosslinked copolymers of glycidyl methacrylate and trimethylolpropane trimethacrylate were prepared by suspension copolymerization and functionalized with diethylenetriamine. The ...
Sensitivity analysis of the variational model for the particulate expansion of fluidized beds
(Taylor and Francis Inc., 2020)
Fluidization experiments were performed by using spherical and non-spherical particles to examine the sensitivity of the variational model to three input parameters: Umf, εmf and Ut. Several correlations for Umf, εmf and ...
High temperature materials: properties, demands and applications / Visokotemperaturski materijali: svojstva, zahtevi i primena
(Association of the Chemical Engineers of Serbia, 2020)
High-temperature materials are used in a wide range of industries and applications such as gas
turbine engines for aircrafts, power and nuclear power plants, different types of furnaces,
including blast furnaces, some ...
Enhancement of antioxidant activity and bioactive compound contents in yellow soybean by plant-extract-based products
(Serbian Biological Society, 2019)
Polyphenols present in different plant cell organelles increase the resistance of plants to various types of environmental stresses. We investigated the possibility of increasing the content of bioactive compounds in the ...
Microstructure and thermal properties of Bi-Sn eutectic alloy
(München : Carl Hanser Verlag, 2020)
Alloys based on Sn and Bi are considered to be one of the best soft lead-free solders due to their low melting temperature and low price. In addition, Bi-Sn alloy with a eutectic composition represents a promising candidate ...
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 ...
Oscillatory Briggs-Rauscher Reaction as “Fingerprint” for Bentonite Identification: The Fine-Tuning of Oscillatory Dynamics with Addition of Clay
(Wiley, 2020)
The oscillatory Briggs‐Rauscher (BR) reaction was applied on solid insoluble materials i. e. bentonite clays. Under the same BR experimental conditions, the addition of identical masses of bentonite of different origin ...
Combined Thermodynamic Description and Experimental Investigation of the Ternary Ag–Bi–Ge System
(Springer, 2019)
In this study, the phase diagram of the ternary Ag–Bi–Ge system was thermodynamically assessed and experimentally investigated, which to our knowledge has not been previously done. Differential thermal analysis (DTA), ...
Jatrophane Diterpenoids With Protective Effect on Human Lymphocytes DNA
(SAGE Journals, 2019)
Two sets of structurally different jatrophanes (1-11 and 13-16), jatrophane 12, and latex extract of 2 Euphorbia species (17 and 18) were tested for in vitro protective effect against chromosome aberrations in peripheral ...
