Antimicrobial activity of propolis
(Faculty of Technology, Leskovac,, 2017)
Object and goals of the study: Therapy with bee products (honey, propolis, royal jelly, pollen) has been known since ancient times and, in developing countries, they are still one of the cheapest ways for prevention and ...
Enhancing properties of concrete by addition of fly ash from a thermal power plant for application in geothermal systems / Poboljšanje svojstava betona dodatkom letećeg pepela iz termoelektrane za primenu u geotermalnim sistemima
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Electric power in Serbia is predominantly provided by thermal power plants. All of eleven existing thermal power plants in Serbia use coal, mainly lignite in the electricity production process thus generating about 6 million ...
Evaluation of nonlinear frequency response method for the hydrolysis of acetic anhydride
(22nd International Congress of Chemical and Process Engineering (CHISA 2016), Prague, Czech Republic, 2016)
The method of nonlinear frequency response (NFR) attempts to predict the outcome of perturbation for the instructive input variables using nonlinear functions within the model equations. The aim of the derived models is ...
Microwave Synthesis of Unusually-Shaped Crystalline RuO2 Supercapacitor
(Academician Evgeni Budevski Institute of Electrochemistry and Energy Systems Bulgarian Academy of Sciences, Sofia, Bulgaria, 2015)
One-step simple temperature-controlled microwave synthesis was applied to prepare nanocrystalline RuO2 dispersion from aqueous RuCl3. RuO2 dispersion was subjected to dynamic light scattering in order to analyze the ...
Shape Controlled, Carbon Supported Pt Anodic Catalysts for DFAFC
(Academician Evgeni Budevski Institute of Electrochemistry and Energy Systems Bulgarian Academy of Sciences, Sofia, Bulgaria, 2015)
Electrocatalytic activity of platinum-based electrocatalysts used in fuel cells has been well recognized. However, significant attention remains on the particle shape and size control of such nanomaterials. Catalytic ...
Effect of substrate type on microhardness of multilayer thin film composite system
(Belgrade : Military Technical Institute, 2014)
Thin metallic multilayer films consisting of nanometer layer thickness deposited on different substrates have shown promising mechanical, electrical and magnetical properties, especially for applications in fabrication of ...
The effect of galacto-oligosaccharides on growth and viability of probiotic bacteria in fermented whey based bevereage
(UDRUŽENJE MIKROBIOLOGA SRBIJE, 2017)
Galacto-oligosaccharides (GOS) are produced from milk lactose during transgalactosylation reaction using -galactosidase. Depending on reaction condition, -galactosidase can, also, hydrolyse lactose, in order to make ...
Electrochemical composite bioceramic coatings based on hydroxyapatite, chitosan and polyvinyl alcohol loaded with gentamicin
(Institute of Technical Sciences of SASA, 2021)
Composite bioceramic coatings have been attracting increasing attention of the scientific
public in recent decades due to the good potential of their use for medical purposes. The
main goal of this scientific research ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
CARBON CRYOGEL AS AN ADSORBENT FOR REMOVAL OF DRUGS AND PESTICIDES FROM WATER
(Society of Physical Chemists of Serbia, 2018)
Carbon cryogel (CC), obtained by pyrolysis of resorcinol–formaldehyde
cryogels, was chemically modified and used for adsorption of drugs and
pesticides from water. FTIR analysis and point of zero charge determination
showed ...
