Nonisothermal melt-crystallization kinetics of hydroxyapatite-filled poly(3-hydroxybutyrate) composites
(Wiley, Hoboken, 2006)
The knowledge of biomedical implants ranging from drug delivery devices to tissue engineering and based on bioresorbable polymer composites is increasing, but the study of the crystallization kinetics of these kinds of ...
The particle distribution functions and applications
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
The new generalized logarithmic equation defined by four parameters, called LG4, was formulated and proposed for describing particle size and shape distributions. For special choice of the parameters the LG4 was reduced ...
Electrochemical oxidation of iodide in aqueous solution
(Elsevier Science Sa, Lausanne, 2006)
Electrochemical oxidation of iodide on DSA (Ti/RuO2) anode was investigated in laboratory cell and semi-industrial electrochemical reactor. Anodic polarization curves in the laboratory cell were obtained in solutions ...
Factors affecting the microstructure of porous ceramics / Faktori koji utiču na mikrostrukturu porozne keramike
(Serbian Chemical Society, Belgrade, 2006)
In this study, porous ceramics were produced by using two methods: the polymeric sponge and foam method. A study of the effect of viscosity on the characteristics of the final product produced using the polymeric sponge ...
Adsorption of phenol and 2,4-dinitrophenol on activated carbon cloth: The influence of sorbent surface acidity and pH
(Taylor & Francis Inc, Philadelphia, 2006)
In this work the effect of the activated carbon cloth surface acidity and pH of the solution on phenols adsorption has been studied. Two phenols, widely different in the terms of their pKa values (phenol and 2,4-dinitrophenol), ...
Synthesis, properties and color assessment of some new 5-(3- and 4-substituted phenylazo)-4,6-dimethyl-3-cyano-2-pyridones / Sinteza, svojstva i obojenost nekih novih 5-(3- i 4-supstituisanih fenilazo)-4,6-dimetil-3-cijano-2-piridona
(Serbian Chemical Society, Belgrade, 2006)
A series of 5-(3- and 4-substituted phenylazo)-4,6-dimethyl-3-cyano-2-pyridones were synthesized, starting from acetylacetone and arenediazonium salt, followed by condensation with cyanoacetamide using a modified literature ...
Electrochemical deposition and corrosion stability of Zn-Co alloy coatings / Elektrohemijsko taloženje i koroziona stabilnost prevlaka Zn-Co legura
(Engineering Society for Corrosion, Belgrade, Serbia, 2006)
The influence of the type of the deposition solution, deposition current density and temperature of deposition solution on the phase structure and corrosion properties of Zn-Co alloys was examined. Alloys were deposited ...
Removal of heavy metal ions from water by complexation-assisted ultrafiltration
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Toxic heavy metals in air, soil and water are global problems that are growing threat to the environment. Therefore, the removal and separation of toxic and environmentally relevant heavy metal ions are a technological ...
Copolymer hydrogels based on N-isopropylacrylamide and itaconic acid
(Elsevier Sci Ltd, Oxford, 2006)
In this study, the swelling behaviour of copolymer hydrogels of N-isopropylacrylamide (NIPAM) and itaconic acid (IA) in response to temperature and pH value of the external media was studied. The equilibrium degree of ...
