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 ...
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 ...
Electrodeposition of Zn-Mn alloys at high current densities from chloride electrolyte
(Springer, New York, 2013)
The Zn-Mn alloy electrodeposition on a steel electrode in chloride electrolyte was investigated with the aim of obtaining deposits with as high as possible Mn percent. It was found that the deposition current density and ...
Electroporation Enhances the Metabolic Activity of Lactobacillus plantarum 564
(University of Zagreb, 2013)
The exposure of bacterial cells to pulsed electric fields (PEF) leads to the reversible formation of pores in the cell membrane if an applied energy is below the critical level. Therefore, the effect of electric field ...
The crystallization of potassium germanate glass with high content of niobium oxide
(University of Chemistry and Technology, Prague, 2012)
Potassium germanate glass with molar ratio [GeO2]/[K2O] = 1.2 and Nb2O5 content of 34 mol% have been synthesized by a melt-quenching method. The crystallization behavior under non-isothermal and isothermal crystallization ...
Immobilization of lipase from Candida rugosa on Sepabeads(A (R)): the effect of lipase oxidation by periodates
(Springer, New York, 2011)
The objective of this paper was the investigation of a suitable Sepabeads(A (R)) support and method for immobilization of lipase from Candida rugosa. Three different supports were used, two with amino groups, (Sepabeads(A ...
Solidification of High Chromium White Cast Iron Alloyed with Vanadium
(Japan Inst Metals, Sendai, 2011)
Experimental results indicate that vanadium affects the solidification process in high chromium iron. Vanadium is distributed between eutectic M7C3 carbide and the matrix, but its content in carbide is considerably higher. ...
Electrochemically synthesized polyaniline as support for lipase immobilization
(Elsevier Science Bv, Amsterdam, 2011)
Electrochemical synthesis of polyaniline support for enzyme immobilization provides easier control over the properties of obtained polymer and reduced risk of biocatalyst inactivation with residues of toxic compounds. In ...
The application of zeolite nanopowder for the construction of the dense composite polymer membranes for carbon dioxide separation
(Inst Materials Physics, Bucharest, 2012)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
