Catalytic activity of Pt-based intermetallics for the hydrogen production - Influence of ionic activator
(Applied Catalysis. A: General, 2007)
In continuous search for advanced electrocatalytic materials for the hydrogen evolution reaction (HER), based on transition metal series, two types of intermetallic compounds, TiPt and MoPt2, were investigated as cathode ...
Antioxidant activity of propolis extracts from Serbia: A polarographic approach
(Food and Chemical Toxicology, 2012)
Antioxidant activity (AO) of commercial propolis extracts (PEs), available on Serbian market, was determined by direct current (DC) polarography. Polarographic anodic current of 5.0 mmol L-1 alkaline solution of H2O2 was ...
Comparison of different electrode materials - Energy requirements in the electrolytic hydrogen evolution process
(Journal of Power Sources, 2006)
Hydrogen is one of the most widely produced commodities in the world economy. The basic technologies for producing hydrogen via the electrolysis of water have long been known. However, there are disadvantages when using ...
Electrolytic D/H isotope separation efficiency and electrocatalytic activity of Mo-Pt intermetallic phases
(Electrochemistry Communications, 2007)
The aim of this work was to investigate efficiency of the electrolytic separation of hydrogen isotopes (D/H), from alkaline 6 M KOH solution as standard electrolyte, on the Mo-Pt intermetallic phases as cathode materials. ...
Electrochemical oscillations during copper electrodissolution/passivation in trifluoroacetic acid induced by current interrupt method
(Corrosion Science, 2014)
Complex oscillatory behavior of electric current and electrode potential were observed during potentiodynamic anodic polarization of Cu in 1 M TFA, applying the current interrupt method for IR drop compensation. This ...
Surface morphology modifications of titanium based implant induced by 40 picosecond laser pulses at 266 nm
(Journal of Alloys and Compounds, 2010)
Surface modification of titanium based implant Ti6Al4V induced by an Nd:YAG laser operating at a wavelength of 266 nm, with pulses of 40 ps, is presented. It is shown that the laser beam at fluences 0.96J cm(-2) and 0.29J ...
Safe trapping of cesium into pollucite structure by hot-pressing method
(Elsevier, 2016)
A simple one-step method with direct thermal conversion at lower temperatures for preparing a stabile Cs-aluminsilicate phase, known as pollucite, is presented. Cs-exchanged form of Na, Ca-LTA type of zeolite (Cs-LTA) was ...
SBA-15 templated mesoporous carbons for 2,4-dichlorophenoxyacetic acid removal
(Chemical Engineering Journal, 2013)
The ordered mesoporous silica SBA-15 was synthesized and used as a template for obtaining mesoporous carbon replicas. Adsorptive removal of pesticide 2,4-dichlorophenoxyacetic acid (2,4-D) from aqueous solutions onto two ...
Synthesis of composite by application of mixed Fe, Mg (hydr)oxides coatings onto bentonite - A use for the removal of Pb(II) from water
(Journal of Hazardous Materials, 2012)
The procedure for obtaining a bentonite based composite involves the application of mixed Fe and Mg hydroxides coatings onto bentonite particles in aqueous suspension and subsequent thermal treatment of the solid phase at ...
Structural, textural and adsorption characteristics of bentonite-based composite
(Microporous and Mesoporous Materials, 2014)
An application of coatings composed of mixed (hydr)oxides over bentonite particles in aqueous suspension, in narrow range of pH, has been proven as a useful method for obtaining bentonite based composite with a developed, ...
