Formulation and characterization of novel liposomes containing histidine for encapsulation of a poorly soluble vitamin
(Elsevier, Amsterdam, 2020)
In this study, development of folic acid-loaded liposomes using a basic amino acid, histidine as a solubilizing agent for folic acid was presented, which tackled the poor solubility of this vitamin. The effect of the ...
Micro-kinetic modelling of photocatalytic CO2 reduction over undoped and N-doped TiO2
(Royal Soc Chemistry, Cambridge, 2020)
CO2 photoreduction is studied using in-house synthesized undoped and N-doped TiO2 nanoparticle photocatalysts. Comparison with the commercial P25 TiO2 powder shows that the synthesized samples are more effective. P25 ...
Atmospheric leaching of copper from oxide-sulfide ore using sulfuric acid / Atmosfersko luženje bakra iz oksidno-sulfidne rude rastvorom sumporne kiseline
(Savez inženjera i tehničara Srbije, Beograd, 2020)
High flexibility of hydrometallurgical operations as well as economic and environmental acceptability, offer the opportunity to selectively obtain metals in the early stages of the processing. This enables the application ...
