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 ...
Eco-friendly technology for gel-coat and fireproofing material production using bio-renewable and waste materials
(OOO «Centr «AЮMЭLЬ», 2020)
Innovative technology has been developed for the production of gelcoat and materials of reduced flammability based on unsaturated polyester resins. These materials were synthesized from raw materials obtained from waste ...
Application of image analysis for cavitation erosion resistance monitoring of some engineering materials
(Bor : University of Belgrade, Technical Faculty, 2023)
Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected

Washing and Desinfection of the Wells Type Reni / Hiperdezinfekcija bunara za vodosnabdevanje tipa Reni
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
We show in this work the treatment procedure utilized for cleaning and desnfection of water in water wells of large capacity as in the case of wells of Belgrade Waterworks. The typical examples of such well of large capacity ...
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 ...
Prirodni radionuklidi u građevinskom materijalu u Srbiji / Natural radionuclides in building materials in Serbia
(Beograd : Institut za nuklearne nauke VinčaBeograd : Društvo za zaštitu od zračenja Srbije i Crne Gore, 2019)
Određivanje sadržaja radionuklida u materijalima koji se koriste u građevinarstvu veoma je važno u cilju procene radiološkog uticaja na zdravlje ljudi. U radu su prikazani rezultati gamaspektrometrijskog merenja prirodnih ...
Thermovision monitoring of concrete heat of hydration / Termovizijski monitoring toplote vlaženja betona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Usled hemijske reakcije Portland cementa, koja se uvek javlja u betonu prilikom očvršćavanja, izvesna količina toplote se razvija. Ova toplota mora biti kvantifikovana, obzirom da ona može oštetiti beton ili pomoći mu, ...
