Energy Efficient Poly(Lactide) Obtaining by Microwave Synthesis
(University of Maribor Press, 2017)
The world is faced with the consequences of drastic reduction in fossil fuel reserves, because of their widespread use, not only as an energy source, but also as a feedstock for monomers obtaining. In order to solve this ...
Superkritični fluidi u procesima dobivanja energije / Supercritical Fluids in Process Related to Obtain Energy
(Akademija nauka i umjetnosti Republike Srpske / Academy of Sciences and Arts of the Republic of Srpska, 2017)
Tehnološki postupak u kome se dobija energija obuhvata osnovne procese i operacije, kao na primer faznu ravnotežu, kinetiku reakcije, sintezu tehnološke šeme, projektovanje postrojenja i ostale faze sve do dobijanja energije ...
Analytical error during selection of reference state in thermodynamic of ideal gas / Analitička greška kod izbora referentnog stanja u termodinamici idealnog gasa
(Banja Luka, Republic of Srpska, Bosnia and Herzegovina : Tehnološki fakultet Univerziteta u Banjoj Luci, 2016)
The paper is based on the fact that the internal energy, enthalpy and enthropy as most important thermodynamic state functions, can not be determined in absolut terms without reference state slections. It is demonstrated ...
