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 ...
Forced periodic reactor operation with simultaneous modulation of two inputs: Nonlinear frequency response analysis and experimental demonstration
(American Institute of Chemical Engineers Annual Meeting (AIChE Annual Meeting), Pittsburgh, USA, 2018)
The classical design of continuously operated chemical reactors assumes that they are operated in a steady-state which is usually optimized and maintained by using appropriate control systems. Nevertheless, it has been ...
Numerical Simulation of Transient Response of Chemical and Biological Micro/Nanofabricated Sensors Operating in Multianalyte Environments
(Institute of Electrical and Electronics Engineers Inc., 2014)
In different kinds of surface-based chemical and biological micro/nanosensors, interpretation of the experimentally obtained data is performed based on approximate solutions for the sensor response, valid for the case of ...
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 ...
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 ...
Lagergren Kinetic Model and Multianalyte Detection by Plasmonic Sensors
(Institute of Electrical and Electronics Engineers Inc., 2014)
This work is dedicated to modeling of adsorption processes in plasmonic sensors. We give a generalization of the Lagergren first order reaction kinetic model to the situations where adsorption takes place in multianalyte ...
Total antioxidant activity in wheat and pea seedlings treated with uncoated and polysaccharide coated CeO2 nanoparticles
(Serbian Plant Physiology SocietyInstitute for Biological Research “Siniša Stanković”, University of BelgradeFaculty of Biology, University of Belgrade, 2018)
In this research, we performed a three-week treatment of seedlings of two agricultural plants in
hydroponics with 200 mg L-1 of uncoated and glucose-, levan- and pullulan coated nCeO2 (G-CeO2, L-CeO2 and P-CeO2). Our aim ...
4-Aminoqionolines as reversible inhibitors of human cholinesterase activity
(Faculty of Military Health Sciences, Czech Republic, 2018)
We synthesised eight derivatives of 4-aminoquinolines differing in the substituents attached to the C(4)-amino group and C(7) carbon of 4-aminoquinoline, and tested their potency to inhibit human AChE and BChE. All of the ...
Structural Characterization of microbial levan by Smith degradation
(Society of Physical Chemists of Serbia, 2016)
In this work, microbial polysaccharide levan from Bacillus licheniformis strain was firstly oxidized to polyaldehyde, then reduced to polyalcohol, completely hydrolyzed, and finally acetylated. Resulting peracetylated ...
Bacterially generated H2SO4 from pyrite, as a leaching agent for phosphorus from phosphate ore
(University of Beograde - Technical Faculty in Bor, 2013)
The object of this study was to investigate the possibility of phosphorus leaching from mixture of
phosphate ore and pyrite minerals, in laboratory conditions using sulfuric acid generated by bacterial culture of ...
