Photodegradation of an azo pyridone dye using TiO2 films prepared by the spray pyrolysis method
(Elsevier Science Sa, Lausanne, 2012)
In this study, the feasibility of preparing porous TiO2 films on a stainless steel substrate from a hydrothermally prepared colloidal TiO2 solution by the spray pyrolysis technique is presented. The prepared samples were ...
Oxidation of carbon monoxide and formic acid on bulk and nanosized Pt-Co alloys
(Springer, New York, 2012)
Bulk Pt3Co and nanosized Pt3Co and PtCo alloys supported on high area carbon were investigated as the electrocatalysts for the COads and HCOOH oxidation. Pt3Co alloy with Co electrochemically leached from the surface (Pt ...
Adding Value to the Oil Cake as a Waste from Oil Processing Industry: Production of Lipase and Protease by Candida utilis in Solid State Fermentation
(Springer, New York, 2012)
Olive oil cake is a by-product from the olive oil processing industry and can be used for the lipase and protease production by Candida utilis in solid state fermentation. Different carbon and nitrogen sources were evaluated, ...
Preparation of TiO2/carbon nanotubes photocatalysts: The influence of the method of oxidation of the carbon nanotubes on the photocatalytic activity of the nanocomposites
(Elsevier Sci Ltd, Oxford, 2012)
A method for the preparation of efficient TiO2/multi-wall carbon nanotubes nanocomposite photocatalysts by precipitation of anatase TiO2 nanoparticles onto differently oxidized carbon nanotubes is presented. The precursor ...
Experimental and numerical analysis of local mechanical properties of globe valve housing
(Chemicke Listy, 2012)
Experimental and Numerical Analysis of Local Mechanical Properties of Globe Valve Housing One of the most widely used industrial valves is globe valve. Due to wide industrial application, the valve is subjected to various ...
Influence of Cr, Mn and Mo Addition on Structure and Properties of V Microalloyed Medium Carbon Steels
(Journal Mater Sci Technol, Shenyang, 2012)
The effect of austenitizing temperature and Cr, Mo and Mn addition on microstructure and mechanical properties of V microalloyed medium carbon steel has been studied by means of metallography and mechanical testing. The ...
Antibacterial activity of heavy metal-loaded natural zeolite
(Elsevier Science Bv, Amsterdam, 2012)
The antibacterial activity of natural zeolitized tuffs containing 2.60 wt.% Cu2+, 1.47 Zn2+ or 0.52 Ni2+ were tested. Antibacterial activities of the zeolites against Escherichia coli and Staphylococcus aureus were tested ...
The effect of applied current density on the surface morphology of deposited calcium phosphate coatings on titanium
(Elsevier, Amsterdam, 2012)
Electrochemical deposition of calcium phosphate coatings on titanium was performed galvanostatically from the aqueous solution of Ca(NO3)(2) and NH4H2PO4 with the current densities between 5.0 and 10 mA cm(-2), for different ...
Bioreactors in tissue engineering
(Cell and Tissue Engineering, 2012)
The underlying philosophy guiding the design and development of advanced bioreactors for tissue engineering purposes is to provide environmental conditions that enable metabolically active cells in threedimensional (3D) ...
The first hydroelectric power plant in the Balkans built on the basis of Tesla’s principles
(International Symposium on History of Machines and Mechanisms, HMM 2012, 2012)
At the end of the 19th century, Serbia was among the first European countries to start electrification. A very bad economic situation, caused by centuries-old slavery and lack of capital, did not prevent the Serbs to start ...
