Piezoelectric polymer/ceramic nanostructures for mechanical energy harvesting
(Belgrade : Serbian Ceramic Society, 2013)
Vibration-based mechanical energy is one of the most accessible energy source in the surroundings. Harvesting this type of energy exhibits a great potential for remote/wireless sensing, charging batteries, and powering ...
Uticaj parametara sinteze i strukture na električna svojstva Ba0,77Sr0,23TiO3
(Čačak : University of Kragujevac, Faculty of Technical Sciences, 2013)
Rezultati istraživanja u oblasti elektronske keramike u najvećoj meri direktno zavise od poznavanja procesa konsolidacije (presovanje i sinterovanje) keramičkih prahova, što, posmatrano sa gledišta poimanja prirode, ukazuje ...
The influence of thin benzoate-doped polyaniline coatings on corrosion protection of mild steel in different environments
(Elsevier, 2013)
The corrosion process of mild steel in the presence of benzoate-doped polyaniline coatings exposed to different environments (3% NaCl, atmosphere, and the Sahara sand) has been investigated. This system was also tested for ...
Mechanochemical treatment of Serbian kaolin clay to obtain high reactive pozzolana
(Belgrade : Serbian Chemical Society, 2013)
Mechanochemical treatment of Serbian kaolin clay was carried out in a planetary ball mill using two different milling media, hardened steel or zirconia vials and balls. The samples obtained with various milling times were ...
Biodiesel synthesis based on CaO·ZnO.K2CO3 as catalyst
(Belgrade : Serbian Ceramic Society, 2013)
The mixed oxide of CaO·ZnO and K2CO3 were prepared by ball milling of CaO and ZnO powders and water, with addition of K2CO3 and afterward by calcination at 700 oC. Influence of different molar ratio of K2CO3 and CaO (x=1, ...
Treatment of Waste Copper Electrolytes Using Insoluble and Soluble Anodes
(Belgrade : ESG, 2013)
The use of copper anodes with non standard content of impurities for the treatment of waste, sulphur acid solutions that came as a result of the industrial process of electrolytic copper refining was investigated. Those ...
Accuracy improvements of consumer-grade 3D sensors for robotic applications
(IEEE, 2013)
Recent advances in development of low-cost 3D sensors, such as Microsoft Kinect, bring attractive opportunities to robot system integrators. The accuracy provided by such sensors is generally unsatisfactory for many robotic ...
Far infrared reflectivity spectra of lead-telluride doped with Mn and Yb
(INOE Publishing House, 2013)
PbTe single crystal samples doped with Mn and Yb were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with different impurity concentrations (total impurity ...
Effects of hydrolysis degree and type of protease on antioxidant activity and functionality of egg white protein hydrolysates
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2013)
Enzymatic hydrolysis of egg white proteins has shown great potential to improve their functional properties such as increased solubility, stability, and digestibility, and to reduce protein allergenicity while still retaining ...
Influence of prolonged sintering time on density and electrical properties of isothermally sintered cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO⋅2Al2O3⋅5SiO2) ...
