Optimization of reactive diluent for bio-based unsaturated polyester resin: A rheological and thermomechanical study
(MDPI, 2021)
Nowadays, unsaturated polyester resins (UPR) are mainly obtained from non-renewable resources. The ever-increasing regulations and the continuous demand for more sustainability have led to extensive research towards more ...
Applying concept of 3d printing concrete in wind tower construction / Primena koncepta 3d štampe betona u izradi vetrogeneratora
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Although a most prominent material in contemporary construction practice due to
its’ obvious advantages, concrete incorporates a number of drawbacks. It is one of the most advantageous principles for decades to enable a ...
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 ...
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, ...
Cytotoxicity of Multifunctional Composites of Amorphous Calcium Phosphate Containing Chitosan on Titanium Obtained by Novel in Situ Anodic Process
(Zvornik : Faculty of Technology, 2021)
Calcium phosphates (CP), amongst which amorphous calcium phosphate (ACP) and hydroxyapatite (HAp), along with Ti and TiO2 layers, have found vast applications in preventive and regenerative medicine due to their excellent ...
Application of Ni(II)-alumina Composites for Electrocatalytic Reduction of 4-nitrophenol
(International Institute for the Science of Sintering, Belgrade, 2020)
Nickel-alumina composites with various content of nickel were synthetized by sol-gel method. The characterization of samples was performed by diffuse reflectance spectroscopy and electrochemical impedance spectroscopy using ...
Synthesis of new praseodymium doped phosphate tungsten bronze
(Belgrade : Serbian Chemical SocietyBelgrade : Serbian Young Chemists’ Club, 2022)
For the preparation of praseodymium doped phosphate tungsten bronze (Pr-PWB), as a
starting material is used 12-tungstophosphoric heteropoly acid H3PW12O40×29H2O
(PWA) [1]. PWA was first converted into H3PW12O40×6H2O ...
What could be the reason for different behavior of phosphate tungsten and phosphate molybdenum bronzes in Briggs-Rauscher reaction: New insight
(Beograd : Institut za multidisciplinarna istraživanja, 2022)
Recently, two different effects of phosphate tungsten (PWB) and phosphate molybdenum (PMoB) bronzes (obtained by thermal treatment), on oscillatory Briggs-Rauscher (BR) dynamic have been found [1]. Although both are insoluble ...
Synthesis and characterization of new dysprosium doped phosphate tungsten bronze
(Institute of Technical Sciences of SASA, 2021)
Dysprosium phosphate tungsten bronze has been successfully synthesized and characterized
(TGA, DSC, FTIR). For the preparation of dysprosium phosphate tungsten bronze (Dy-PWB), as a starting material is used 12-tungstophosporic ...
The behavior of cerium doped phosphate tungsten bronze in Briggs-Rauscher oscillatory reaction
(Serbian Ceramic Society, 2022)
The Briggs-Rauscher (BR) reaction is an oscillating reaction in which the oxidation of malonic acid (CH2(COOH)2) in the presence of hydrogen peroxide (H2O2) and potassium iodate (KIO3) is catalyzed with a metal ion (usually ...
