Synthesis and characterization of Na0.4MnO2 as cathode material for aqueous sodium-ion batteries
(Belgrade : Institute of Technical Sciences of SASA, 2018)
The application of rechargeable batteries is growing significantly and there is a need for developing cheaper batteries with good performances. Sodium-ion batteries could be a viable option due to higher abundance of sodium ...
Point defect-enhanced optical and photoelectrochemical water splitting activity of nanostructured Zn1-xFeyO(1-x+1.5y)
(Belgrade : Materials Research Society of Serbia, 2019)
Even has been under study since 1935, zinc oxide (ZnO) based materials still attract a huge scientific attention. Owing to a wide band gap energy (3.37 eV at room temperature) and a large exciton binding energy (60 meV) ...
Tuning the optical, electrical and photoelectrocatalytic properties of Zno materials by varying of intrinsic defects concentration
(Budapest : [s. n.], 2019)
During the last decade zinc oxide (ZnO) has attracted considerable attention as a promising material for electronic, optoelectronic and spintronic devices. ZnO has a wide bandgap (3.37 eV at room temperature) and relatively ...
Synthesis temperature influence on the structure, morphology and electrochemical performance of NaxMnO2 as cathode materials for sodium-ion rechearchable batteries
(Belgrade : Institute of Technical Sciences of SASA, 2019)
The lithium-ion batteries are the most commonly used for energy storage in portable devices. Since lithium is relatively rare on earth but rapidly consumed, it is necessary to find an adequate replacement. Owing to the ...
Structural, photocatalytic and photoelectrochemical characteristics of ZnO nanoparticles synthesized by a glycine-nitrate process
(Budapest : [s. n.], 2019)
Zinc oxide is a semiconductor material which still, after a century of scientific research, shows great potential in modern day utilisements such as heterogenous photocatalysis of organic pollutants and as a photoanode ...
Open Access Journals in Serbia: Policies and Practices
(Belgrade : National Library of Serbia, 2017)
This study is the result of the project Revisiting Open Access Journal Policies and Practices in Serbia, funded through the EIFL Open Access Programme. The project was implemented by the Serbian Library Consortium for ...
The influence of synthesis conditions on the redox behaviour of LiFePO4 in aqueous solution
(Elsevier, 2019)
To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in ...
Structural and electrical properties of geopolymer materials based on different precursors (kaolin, bentonite and diatomite)
(Skopje : Institute of Chemistry, Faculty of Natural Sciences and Mathematics, Ss. Cyril & Methodius University, 2019)
Geopolymers (GP) were successfully synthesized from metabentonite (MB), metadiatomite (MD) and metakaolinite (MK). Characterization of their phase structure and microstructure was performed by XRD, FTIR, SEM/EDX methods. ...
Properties of 3Y-TZP zirconia ceramics with graphene addition obtained by spark plasma sintering
(Elsevier, 2018)
In this study the influence of graphene addition on the microstructure, phase composition, mechanical, and electrical properties of 3Y-TZP ceramics was investigated. Blends of pure 3Y-TZP and with addition of 1 − 4 vol% ...
Implementation architecture of a home robot assistant
(Tel Aviv : The Israeli Robotics Association, 2016)
This paper deals with development of a personal robot functioning as a part of a smart home. The overall system is based on the cloud computing model to leverage processing, data sensing and communication power of the ...
