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 ...
Electrochemical oxidation of 2,4,6-trichlorophenol on iron-doped nanozirconia cerami / Elektrohemijska oksidacija 2,4,6-trihlorfenola na nano-cirkonijum - oksidnoj matrici dopiranoj gvožđem
(Beograd: Srpsko hemijsko društvo, 2021)
Solvothermaly synthesized zirconium oxide nanopowders, pure and
doped with various amounts of iron ions (1–20 %), were used as modifiers of
glassy carbon electrodes. The modified electrodes were tested in the reaction ...
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 ...
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 ...
Basic principles of 3 D concrete printing in the light of sustainable development
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
Although conservative, the construction industry must be transformed in line with new technologies. Adopting the concept of 3D printing can provide a handful of benefits in terms of creativity, flexibility, less waste ...
Synthesis and characterization of new cerium doped phosphate tungsten bronze
(Society of Physical Chemists of Serbia, 2021)
Cerium doped phosphate tungsten bronze (Ce-PWB) was synthetized by phase transformations of CePW12O40x6H2O (Ce-6-PWA) salt. The solid-solid transformations of Keggin's anion of this salt, including dehydration processes ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior de Investigaciones Cientificas - CSIC, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
