Electrochemical methods for corrosion testing of Ce-based coatings prepared on AA6060 alloy by the dip immersion method / Elektrohemijske metode za ispitivanje korozione stabilnosti prevlaka na bazi cerijuma dobijenih potapanjem na leguri AA6060
(Serbian Chemical Society, 2013)
Dip-immersion is a simple and cost-effective method for the preparation of Ce-based conversion coatings (CeCCs), a promising alternative to toxic chromate coatings, on metal substrates. In this work, CeCCs were prepared ...
Cerium oxide as conversion coating for the corrosion protection of aluminum
(International Association of Physical Chemists (IAPC), 2013)
CeO2 coatings were formed on the aluminum after Al surface preparation, by dripping the ceria sol, previously prepared by forced hydrolysis of Ce(NO3)4. The anticorrosive properties of ceria coatings were investigated by ...
Total synthesis and biological evaluation of (-)-atrop-abyssomicin C
(Royal Soc Chemistry, Cambridge, 2013)
Enantioselective synthesis of a marine antibiotic (-)-atrop-abyssomicin C was accomplished in 21 steps, in 1.8% overall yield (4%, based on the recovered starting material). The key steps of the synthesis are the formation ...
Photocatalytic degradation of azo pyridone dye: Optimization using response surface methodology
(Desalination Publ, Hopkinton, 2013)
Response surface methodology (RSM) and central composite design have been applied to describe and optimize photocatalytic degradation of azo pyridone dye using TiO2, H2O2, and simulated sun light. The mutual interactions ...
Study of the Electrochemical Oxidation of Reactive Textile Dyes Using Platinum Electrode
(Esg, Belgrade, 2013)
Textile industries are widespread in developing countries. Among the various processes in the textile industry, the dyeing process uses large volumes of water for dyeing, fixing and washing. Textile industry wastewater is ...
Degradation of triketone herbicides, mesotrione and sulcotrione, using advanced oxidation processes
(Elsevier, 2013)
Degradation of two triketone herbicides, mesotrione and sulcotrione, was studied using four different advanced oxidation processes (AOPs): ozonization, dielectric barrier discharge (DBD reactor), photocatalysis and Fenton ...
Solvatochromic and quantum chemical investigations of newly synthesized succinimides: substituent effect on intramolecular charge transfer
(Springer Wien, Wien, 2013)
Two series of 1-aryl-3-phenyl- and 1-aryl-3,3-diphenylpyrrolidine-2,5-diones were synthesized and their solvatochromic properties were studied in a set of 15 solvents of different polarity. The effect of specific and ...
Preparation, characterization and photocatalytic activity of lanthanum and vanadium co-doped mesoporous TiO2 for azo-dye degradation
(Elsevier, 2013)
Titanium dioxide photocatalysts co-doped with lanthanum and vanadium were prepared by a facile microwave-assisted hydrothermal method and characterized by XRD, SEM, N-2 physisorption at 77 K and DRS. The characterization ...

Morphological and crystallographic characteristics of electrodeposited lead from a concentrated electrolyte
(The Royal Society of Chemistry, 2013)
Electrodeposition of lead from a concentrated nitrate solution was examined by scanning electron microscopy (SEM) and by X-ray diffraction (XRD) analysis of the obtained powder particles. Single crystals of the (111) ...
