Experimental and theoretical study of nanostructured Ca1-xGdxMnO3 (x=0.05; 0.1; 0.15; 0.2)
(Belgrade : Serbian Ceramic Society, 2021)
Experimental and theoretical methods have been used to investigate the octahedral tilting and related effects of Ca1-xGdxMnO3(x = 0.05; 0.1; 0.15; 0.2) compound. Both methods have shown that orthorhombic-perovskite structure ...
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 ...
Reversible intercalation/deintercalation of lithium ions within γ-LiV2O5 polymorph
(Belgrade : Materials Research Society of Serbia, 2021)
The electrochemical insertion of lithium ions in V2O5 produces various crystal structures depending on lithium concentration. Compositions with lithium content in the range of 1 ≤ x ≤ 1.8 take orthorhombic γ-LixV2O5 form. ...
Sinteza i struktura bakterijske celuloze primenom bakterija sirćetnog vrenja
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2021)
Kao jedan od najzastupljenijih biopolimera na Zemlji, celuloza je našla primenu u prehrambenoj industriji, biomedicini i biotehnologiji. Dobijanje celuloznih vlakana iz biljaka je praćeno prisustvom nusproizvoda, čije je ...
Preparation and characterization of ZrB2-TiB2 based composites for hypersonic systems
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
ZrB2 ceramics are considered potential materials for hypersonic systems in view of the melting point exceeding 3000 °C and excellent ablation resistance. Second phases, including SiC or CrB2, further improve the oxidation ...
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 ...
Additive-free resveratrol micro- and nanoparticles and assessment of their toxicity
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Resveratrol, polyphenol from stilbene family, has demonstrated beneficial effects on human health in numerous studies. Among these effects are cardioprotective, anti-cancer, neuroprotective, antimicrobial and other. In ...
Structure and Properties of Nanocrystalline Tetragonal BaTiO3 Prepared by Combustion Solid State Synthesis
(Belgrade : ETRAN, 2020)
Barium titanate (BaTiO3) attracts high scientific and technological attention due to good dielectric and electromechanical properties. Although BaTiO3 is one of the most frequently investigated ferroelectric materials, the ...
