A study of the removal of copper ions from aqueous solution using clinoptilolite from Serbia
(Springer, New York, 2011)
Toxic metal contamination of waste waters can be mitigated by metal adsorption to clay and zeolitic minerals, but in developing countries such environmental remediation can be cost prohibitive if these minerals are not ...
Synthesis of N-(3-and 4-substituted phenyl)-O-isobutyl thionocarbamates from O-isobutyl xanthate and amines using a nano-platinum multi-walled carbon nanotube catalyst
(Springer Wien, Wien, 2011)
Twelve N-(3- and 4-substituted phenyl)-O-isobutyl thionocarbamates, eight of which are novel, were synthesized from O-isobutyl xanthate and 3- and 4-substituted anilines in the presence of a nano-platinum aminophenyl ...
Synthesis, structure, and solvatochromic properties of pharmacologically active 5-substituted 5-phenylhydantoins
(Springer Wien, Wien, 2011)
A series of 5-substituted 5-phenylhydantoins was synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability ...
Cancer Incidence in a Population Living Near a Petrochemical Facility and Oil Refinery
(Collegium Antropologicum, 2011)
There is growing concern that pollution from petrochemical and oil refinery installations in Pancevo (Serbia) has increased the incidence of various diseases including cancer The aim of our study was to investigate cancer ...
Inhibition of Microbial Growth by Silver-Starch Nanocomposite Thin Films
(Vsp Bv, Leiden, 2011)
A sago starch biopolymer with embedded silver nanoparticles has been studied as a material for the prevention of microbial growth. Approximately 8 nm in size, silver nanoparticles have been synthesized by reduction of the ...
The formation of oxide nanoparticles on the surface of natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Nanoparticles of NiO, ZnO and Cu(2)O crystallize when the Ni-, Zn- and Cu-exchanged natural clinoptilolite, respectively, are dehydrated by heating in air at 550 degrees C. The dehydration of Mn-exchanged clinoptilolite ...
High-temperature deformation behaviour of Ti3Al-11Nb intermetallic
(Carl Hanser Verlag, Munich, 2011)
A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish ...
Reactivation of a thermostable lipase by solid phase unfolding/refolding Effect of cysteine residues on refolding efficiency
(Elsevier Science Inc, New York, 2011)
Lipase from Geobacillus thermocatenulatus (BTL2) was immobilized in two different matrixes. In one derivative, the enzyme was immobilized on agarose activated with cyanogen bromide (CNBr-BTL2) via its most reactive superficial ...
Total polyphenols and antioxidative activity of water extracts of spent coffee
(Karger, Basel, 2011)
Experimental determination and modeling of densities and refractive indices of the binary systems alcohol plus dicyclohexylamine at T = (288.15-323.15)K
(Elsevier, Amsterdam, 2011)
The experimental density rho and refractive index n(D) data have been determined for the systems of dicyclohexilamine with 1-propanol, or 1-butanol, or 2-butanol, or 1-pentanol, in the temperature range (288.15, 293.15, ...
