Triplet state (anti)aromaticity of some monoheterocyclic analogues of benzene, naphthalene and anthracene
(Royal Society of Chemistry, 2021)
Aromaticity–antiaromaticity switch upon singlet–triplet transition of some biologically and synthetically
important monoheterocycles (heteroatom = N, O, Si, P, and S) derived from benzene, naphthalene and
anthracene was ...
Comparative Study of the Essential Oil and Hydrosol Composition of Sweet Wormwood (Artemisia annua L.) from Serbia
(Wiley, 2022)
The most abundant volatile compounds of sweet wormwood (Artemisia annua L.) essential oil were artemisia ketone (25.4 %) and trans-caryophyllene (10.2 %), followed by 1,8-cineole, camphor, germacrene D and β-selinene. The ...
Synthesis of novel pyridinium based compounds and their possible application in dye-sensitized solar cells
(Elsevier, 2023)
Five novel D-π-A structured pyridinium based compounds, bearing different electron-donating units were synthesized, minutely characterized, and their solvatochromic and electronic properties were investigated. Subsequently, ...
The impact of the polycaprolactone content on the properties of polyurethane networks
(Elsevier, 2023)
The influence of soft segment (SS) content on the properties of novel polyurethane networks (PUNs), prepared by a two-step polymerization in a solvent mixture, was investigated in this work. Hyperbranched polyester of the ...
Thermal analysis and phase changes of mechanochemically activated sodium carbonate
(Elsevier, 2022)
Sodium carbonate is a well-known material for being used as a good sorbent of carbon dioxide from the atmosphere, and as such has gained increasing importance in environmental protection. In order to enhance its sorption ...
Short-term study of biological degradation of diesel oil by bacteria isolated from petroleum- contaminated soil
(Taylor & Francis, 2024)
The use of fossil fuels leads to environmental contamination during their extraction, processing and distribution. Microbial biodegradation provides a sustainable method for cleaning contaminated areas which follows the ...
Heat transfer to a sphere immersed in a fluidized bed of coarse particles with transition from bubbling to turbulent flow regime
(Taylor & Francis, 2023)
The present work concerns an experimental study on heat transfer in gas-solid fluidized bed of coarse (Geldart D) particles to a larger immersed sphere at high superficial velocities from 2 to 5.5 Umf. The heat transfer ...
Determination of lipophilicity and ionization of fentanyl and its 3‑substituted analogs by reversed-phase thin-layer chromatography
(Elsevier, 2022)
Lipophilicity and ionization constant of sixteen fentanyl analogues were investigated by reversed-phase thin-layer chromatography (RP-TLC). Fourteen compounds have nitrogen containing groups at C-3 position of the piperidine ...
Influence of cation−π interactions to the structural stability of phycocyanin proteins: A computational study
(Elsevier, 2022)
The influences of cation−π interactions in phycocyanin proteins and their environmental preferences were analyzed. The number of interactions formed by arginine showed to be higher than those formed by the lysine in the ...
Concentration and mobility of trace elements (Li, Ba, Sr, Ag, Hg, B) and macronutrients (Ca, Mg, K) in soil-orchid system on different bedrock types
(Springer, 2022)
The mobility of chemical elements in the soil-orchid system has been poorly studied. The aim of this study is to evaluate the uptake and mobility of several trace (Li, Ba, Sr, Ag, Hg, and B) and macronutrients (Ca, Mg, and ...
