Synthesis and characterization of poly(ester ether siloxane)s
(Wiley, 2006)
A series of novel thermoplastic elastomers based on ABA-type triblock prepolymers, poly[(propylene oxide)–(dimethylsiloxane)–(propylene oxide)] (PPO-PDMS-PPO), as the soft segments, and poly(butylene terephthalate) (PBT), ...
Problem and Solution of UV–Vis Time-Based Measurements of a Chemical System Involving Gas Product: Application to the Bray–Liebhafsky Oscillatory Reaction
(American Chemical Society (ACS), 2021)
Ultraviolet (UV)–visible (Vis) spectroscopy is widely used in all modern laboratories as a routine method of analysis. The monitoring of chemical reactions in an aqueous solution involving a gas product is a demanding task ...
In vitro antitumor actions of extracts from endemic plant Helichrysum zivojinii
(Biomed Central Ltd, London, 2013)
Background: The aim of this research was to determine the intensity and mechanisms of the cytotoxic actions of five extracts isolated from the endemic plant species Helichrysum zivojinii Cernjavski & Soska (family Asteraceae) ...
Design and In Vitro Biological Evaluation of a Novel Organotin(IV) Complex with 1-(4-Carboxyphenyl)-3-ethyl-3-methylpyrrolidine-2,5-dione
(Hindawi, 2019)
A novel triphenyltin(IV) compound with 1-(4-carboxyphenyl)-3-ethyl-3-methylpyrrolidine-2,5-dione was synthesized and characterized by IR, NMR spectroscopy, mass spectrometry, and elemental analysis. In vitro anticancer ...
Entropy change of open thermodynamic systems in self-organizing processes
(Society of Thermal Engineers of Serbia, 2014)
The thermodynamic models available in the literature predict that during self-organizing processes the entropy of a cell considered as an open thermodynamic system
decreases. This prediction leads to conclusion that cell ...
Antiproliferative activity of β-hydroxy- β-arylalkanoic acids
(MDPI, 2007)
Article describes the synthesis of fifteen β-hydroxy- β-arylalkanoic acids by Reformatsky reaction using the 1-ethoxyethyl-2- bromoalkanoates, aromatic or cycloalkyl ketones or aromatic aldehydes. The short survey of ...
Removal of heavy metals from aqueous solutions using natural and Fe(III) oxyhydroxide clinoptilolite
(Springer, 2013)
The increasing levels of industrial wastewater released to the environment present a serious
threat to human health, living resources, and ecological systems. Fe-modified zeolites were developed and tested for removal of ...
Spherical aromaticity of Jahn-Teller active fullerene ions
(Springer Wien, Wien, 2013)
Density functional theory was applied to compute the nucleus-independent chemical shifts of fullerene (C-60), the fullerene ion C-60 (10+), and the Jahn-Teller active fullerene anion C-60 (-) and cation C-60 (+). Positioning ...
Synthesis, characterization, DFT calculations and antimicrobial activity of pentagonal-bipyramidal Zn(II) and Cd(II) complexes with 2,6-diacetylpyridine-bis(trimethylammoniumacetohydrazone)
(Taylor & Francis Ltd, Abingdon, 2016)
Isothiocyanate complexes of Zn(II) and Cd(II) with the condensation product of 2,6-diacetylpyridine and trimethylammoniumacetohydrazide (Girard's T reagent) were synthesized, characterized, and their antimicrobial activities ...
Preparation and Characterization of Novel Glycidyl Methacrylate/Clay Nanocomposites
(Serbia : International Institute for the Science of Sintering (IISS), 2022)
The impact of the type and amounts of nanofiller on the features of the glycidyl methacrylate-co-ethylene glycol dimethacrylate (GMA-co-EGDMA)/organomodified montmorillonite (OMt) nanocomposites that were prepared by in ...
