Identification of adsorption kinetics with dual mechanisms by nonlinear frequency response method
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
A characteristic example of the inability of the classical linear frequency response (FR) method to identify the correct kinetic mechanism is adsorption of n-hexane on silicalite-1. The linear FR has resulted in bimodal ...
Solvent and substituent effect on electronic spectra of N-(4-substituted phenyl)-2,3-diphenylpropanamides
(Arkivoc, 2006)
The UV absorption spectra (200-400 nm) of eleven N-(4-substituted phenyl)-2,3-diphenyl-propanamides 1 have been recorded in fourteen solvents of different polarity. A simple Hammett equation was used to study the effects ...
Thermal stability of cordierite/silicon carbide composites after cyclic thermal shock
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
In this paper composite material made from silicium carbide and cordierite was used in experiments. Behavior of the material in conditions of rapid temperature changes was investigated. Modified water quench test was applied ...
Low-temperature plasma modification of wool
(Tekstil, 2005)
Low-temperature plasma treatment causes modification of specific wool properties (felting shrinkage, wettability, dyeability, printability, pilling) as a result of interaction between active plasma particles and fibre ...
Implementation of a quality management system in meteorological practice in Serbia
(Springer, New York, 2008)
An optional approach in the meteorological service Quality Management System (QMS) based on the case study of the Republic Hydrometeorological Service (MHS) of Serbia is presented and discussed in this paper. The idea is ...
Crystallization shelves for laboratory furnaces
(Wiley-VCH Verlag Gmbh, Weinheim, 2007)
Several designs of air coolers (modular bilateral "crystallization shelves"), installed in laboratory furnaces are presented. The setup allows easy regulation and simultaneous crystallization of several substances at ...
Effect of surface modification by Fe-P alloys on corrosion behaviour of epoxy coatings electrodeposited on steel
(Bulletin of Electrochemistry, 2001)
Corrosion behaviour of electrodeposited epoxy coatings on electrochemically modified steel surface by Fe-P alloys of different chemical and phase structures has been investigated by exposure to 3% NaCl. The electrochemical ...
Prediction of excess molar volumes of binary mixtures of organic compounds from refractive indices
(Versita, Warsaw, 2008)
The excess molar volumes of 51 binary mixtures containing diverse groups of organic compounds: alcohols (methanol, ethanol, propan-1-ol, butan-1-ol, pentan-1-ol, hexan-1-ol, and heptan-1-ol), (cyclo-) alkanes (hexane, ...
An empirical equation for temperature and pressure dependence of liquid heat capacity
(Elsevier, Amsterdam, 2009)
A new empirical equation for liquid heat capacity calculation, as a function of temperature and pressure is recommended. This four-parameter equation was tested and compared to the four-parameter equation developed by ...
Synthesis of substituted 3-cyano-2-pyridones: Part IV. Influence of 3-alkyl-2,4-pentanedione and N-alkyl cyanoacetamide structure on the enzyme catalyzed synthesis of substituted 3-cyano-2-pyridones
(Natl Inst Science Communication, New Delhi, 2006)
Lipase from Candida rugosa has been used to Study the influence of 3-alkyl-2,4-pentanedione and N-alkyl cyanoacetamide Structure on the enzyme catalyzed reaction of pyridone ring formation in water at 40 degrees C. Starting ...
