Pretreatment of used vegetable oil using CaO and CaO-ZnO for biodiesel production
(Czech Society of Chemical Engineering, 2014)
The study of Zn-Co alloy coatings electrochemically deposited by pulse current / Ispitivanje prevlaka Zn-Co legura dobijenih pulsirajućom strujom
(Association of Chemical Engineers of Serbia, 2012)
The electrochemical deposition by pulse current of Zn-Co alloy coatings on steel was examined, with the aim to find out whether pulse plating could produce alloys that could offer a better corrosion protection. The influence ...
SiC synthesis using natural Mg-silicates
(International Institute for the Science of Sintering, Beograd, 2012)
The silicon carbide powders are prepared by carbothermal reduction of domestic mineral resources (white and brown sepiolite), at relatively low temperatures (1200 - 1600oC). Carbothermal reduction process is greatly ...
Electrochemical characteristics of polyaniline/lead-dioxide power source
(Hunedoara : University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2012)
Polyaniline (PANI) anode, electrochemically formed on graphite from aniline containing sulfuric acid solution, and electrochemically formed thin film lead dioxide cathode, were investigated for possible applications as ...
Modelling of the substance transfer in the gas-liquid system with chemical reaction
(Petroleum and Coal, 2012)
In this paper substance transfer phenomena in the multistage reactive system were investigated.Substance transfer between liquid and gas phases in a distillation packed column with reactionesterification was examined. ...
