Roots of the willow gentian (Gentiana asclepiadea L., Gentianaceae) are used in folk medicine to treat gastrointestinal diseases.Spray drying is the most commonly used technique for microencapsulation of plant extracts in ...
Layered CaV2O6 as promising electrode material for multivalent storage
(Belgrade : Institute of Technical Sciences of SASA, 2021)
While the world is facing a higher demand for lithium, its limited resources associated with the high price, are becoming problematic. Other crucial drawbacks of Li-ion batteries are their toxicity and safety concerns. ...
Investigation of photo(electro)catalytic efficiency of BaTi1-xSnx, ZnO and ZnO@BaTi1-xSnx (x = 0, 0.05, 0.10) powders
(Belgrade : Institute of Technical Sciences of SASA, 2021)
The aim of this research was to improve photo(electro)catalytic properties of BaTi1-xSnx (BTS, x = 0, 0.05, 0.10) powders. For that purpose we employed ZnO to prepare ZnO@BTS composite. In situ microwave processing of a ...
Simply prepared Mg-V-O as potential cathode material for rechargeable aqueous magnesium ion batteries
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Although today widely used in electronic devices and electric vehicles, lithium ion batteries encounter problem of future application, resulting from limited Li resources, relatively high costs and operational safety ...
Application of supercritical carbon dioxide for making perovskite photodiode
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Perovskite solar cells reached high efficiency in a short period. When perovskite was applied for the first time as photovoltaics, power conversion efficiency (PCE) was less than 3 %. Up to now, PCE is over 29 %. In ...
