Structural dissymmetrization of optically anisotropic Grs64±1Adr36±1Sps2 grandite from Meka Presedla (Kopaonik Mt., Serbia)
(Cambridge University Press, 2020)
In this paper, grandite core with Grs64±1Adr36±1Sps2 composition was crystallographically studied. This core represents zone A of the macroscopically visible five A–E zones of the optically anisotropic Grs58–64Adr36–42Sps2 ...
A thermodynamic insight into viral infections: do viruses in a lytic cycle hijack cell metabolism due to their low Gibbs energy?
(Elsevier, 2020)
After adsorption and penetration, a virus hijacks a cell's metabolic machinery and uses it as a medium for its reproduction and growth through multiplication. Growth is competitive, since the same precursors and machinery ...
Postupak solidifkacije i stabilizacije teških metala iz otpadnih rudničkih voda adsorbovanih na peletama u ekološki prihvatljiv građevinski materijal pepela / Procedure of solidification and stabilization of heavy metals from mine waste waters adsorbed on fly ash pellets into enviromentally acceptable building material
(Zavod za intelektualnu svojinu Republike Srbije, 2020)
Stabilizacija teških metala, posebno bakra, iz kiselih otpadnih rudničkih voda izvodi se njihovom solidifikacijom u sumpor polimerni beton kao ekološki prihvatljiv građevinski materijal. Postupak se izvodi tako što se u ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Elsevier, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, N2 physisorption, SEM, and ...
Effect of Fe3+ ion doping on photocatalytic ability of nanozirconia ceramic to degrade 2, 4, 6- trichlorophenol
(Elsevier, 2020)
Pure and a series of Fe3+ doped zirconia nanopowders were synthesized combining colloidal chemistry and solvothermal method from organometallic precursors in order to correlate doping and properties of zirconia matrix. ...
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 ...
Flocculation study of natural quartz sample using anionic polyacrylamide / Проучавања флокулације узорка природног кварца у присуству анјонског полиакриламида
(Академија наука и умјетности РС, 2020)
The waste sludge generated during processing of iron ore in the Omarska mine (The Republic of Srpska, Bosnia and Herzegovina) is fine-grained (<15μm), containing relatively high concentrations of iron, and quartz as its ...
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, ...
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 ...
