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 ...
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,

Influence of mechanochemical activation of components on synthesis of cordierite ceramics for application in electronics / Uticaj mehanohemijske aktivacije komponenti na sintezu kordijeritne keramike za primenu u elektronici
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
The properties of cordierite, 2MgO·2Al2O3·5SiO2, makes this ceramics nowadays an attractive
material, which can be used for various applications in electronics. As the sintering temperature of
cordierite is very high ...
Optimization of methanol synthesis under forced dynamic operation
(4th Indo-German Workshop on Advances in Materials, Reaction& Separation Processes, Berlin, Germany, 2020)
Methanol is an essential primary chemical in the chemical industry. Further, there is a
growing interest in using methanol also for chemical energy storage. Excess electrical
wind or solar energy can be converted to ...
Forced periodic reactor operation
(4th Indo-German Workshop on Advances in Materials, Reaction& Separation Processes, Berlin, Germany, 2020)
We used the nonlinear frequency response (NFR) method in order to identify forced periodic conditions under which the acetic acid anhydride hydrolysis (chosen as a test reaction) can be favorably performed in a CSTR. Based ...
Numerical evaluation of aerodynamic performances of vertical-axis wind turbine rotor with flow concentrator
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
With wind energy extraction constantly increasing, the interest in small-scale urban wind turbines
is also expanding. Given that these machines often work in adverse operating conditions
(Earth’s boundary layer, vortex ...
Lignicolous mushroom Fomitopsis pinicola as a potent inhibitor of lipid peroxidation
(Novi sad: Matica Srpska, 2022)
Excessive production of reactive oxygen species (ROS) often results in irreversible cell damage and leads to a number of disorders such as hypertension, heart disease, diabetes, inflammation, premature aging and cancer. ...
Examples of Wide Microwave Bandpass Microstrip Filters on Felt Substrate
(Belgrade : Institute of Electrical and Electronics Engineers Inc., 2021)
Application of one type of wide bandpass filter on felt (textile) substrate is introduced. Copper tape and conductive textile are used for metallization (conductive layer). It is an initial work. The patterns were done in ...
Instability region in models of nonlinear reaction systems. The Stoichiometric Network Analysis
(Serbian academy of nonlinear sciences, 2020)
Stability analysis of reaction systems is described by the application of the Stoichiometric Network Analysis to the three-variable-autocatalator. Although simple, this model is complex enough to describe complex forms of ...
