Theoretical Study of σ-hole Bonding between Selenium Atoms in Crystal Structures of Organoselenium Compounds
(Stellenbosch, South Africa : Department of Chemical and Polymer Science at Stellenbosch University, 2020)
Non-covalent interactions involving selenium atoms are of great importance in chemistry and biochemistry due to the prominent role of selenium-containing molecules (like Se-antioxidants and selenoenzymes) in different ...
Crude extracts of cinnamon and oregano spices as components of pullulan based edible films
(Vinča - Belgrade, Serbia : Vinča Institute of nuclear sciences, 2018)
Pullulan based films were prepared with crude extracts of cinnamon and oregano spices. Obtained films were characterized by FTIR-ATR spectroscopy and their antioxidant and antimicrobial properties were evaluated. These ...
Response Surface Methodology and Artificial Neural Network-Based Models for Predicting Roughness of Cu coatings
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2020)
Copper coatings are produced on silicon wafer by electrodeposition (ED) in pulsating current (PC) regime. Electrodeposition was performed at various current density amplitudes in the range of 80−140 mA cm-2, frequency in ...
Synthesis of chromogenic substrate for screening of pullulan-degrading microorganisms
(Belgrade : Society of Physical Chemists of Serbia, 2014)
A chromogenic substrate was obtained by coupling azo dye Congo red to microbial polysaccharide pullulan. The synthesized product was characterized by spectral techniques and elemental analysis. Results showed that dye-labelled ...
Application of graphene quantum dots in heavy metals and pesticides detection
(Szeged : University of Szeged, 2020)
Graphene Quantum Dots (GQDs) were produced using electrochemical oxidation of graphite rods. Obtained GQDs were gamma-irradiated in the presence of the N atoms source, ethylenediamine. Both structural and morphological ...
Biodegradability of novel graft copolymer with levan and polystyrene
(Society of Environmental Toxicology and Chemistry Europe, 2018)
In the present study, graft copolymer with microbial levan and styrene was synthetized, characterized and its biodegradable potential was investigated.
POPs Level of Environmental Sample in Serbia
(Japan Society for Environmental Chemistry, 2017)
Persistent organic pollutants (POPs) are chemicals that persist in the environment, bioaccumulate through the food web, and exhibit toxic effects that may threaten the health of humans and wildlife. Active air sampler (AAS) ...
Synthesis of gold nanoparticles using aldehyde functionalized levan as reducing agent
(Belgrade : Society of Physical Chemists of Serbia, 2014)
In this work, gold nanoparticles (AuNPs) were synthesized in aqueous solution by aldehyde functionalized microbial polysaccharide levan as a reducing agent. Resulting nanoparticles were characterized by UV-Vis spectroscopy ...
Vacuum Sensing Based on the Influence of Gas Pressure on Thermal Time Constant
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper we propose a novel operating principle for thermal vacuum sensor. The sensor considered in this work consists of thermopiles and thermally isolating membrane structure. The operating principle of such sensor ...
Investigation of physicochemical properties and potential biological activity of 2-pyridine-(thio)carbohydrazone derivatives / Испитивање физичко-хемијских својстава и потенцијалне биолошке активности деривата 2-пиридин-(тио) карбохидразона
(Banja Luka : Akademija nauka i unjetnosti Republike Srpske, 2022)
Карбохидразони и њихови тио-аналози представљају
једињења добијена кондензацијом карбохидразида, односно тиокарбохи-
дразида са карбонилним једињењима. Захваљујући њиховој структури,
