Polymerization of Itaconic Acid Initiated by a Potassium Persulfate/N,N-Dimethylethanolamine System
(Wiley, Hoboken, 2008)
The synthesis and characterization of poly (itaconic acid) (PIA) with a novel initiator/activator system is presented. The initiator in this system was potassium persulfate, whereas the activator was N,N-dimethylethanolamine ...
Method for determining refractory specimen heat resistance
(Springer, New York, 2008)
The most important properties governing the operation of refractories are refractoriness, service temperature and heat resistance. The heat resistance of specimens based on Al2O3 is determined by a standard laboratory ...
The effects of hemicelluloses and lignin removal on water uptake behavior of hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
This study investigated the individual influences of hemicelluloses and lignin removal on the water uptake behavior of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin were obtained by ...
TIMS and MALDI TOF of endohedral Li-n"C-70 (n=1-3) metallofullerenes
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
Using the ion implantation technique (introducing negatively charged fullerene into a low temperature lithium plasma column by a strong axial magnetic field) endohedral fullerenes Li"C-70, Li-2"C-70 and Li-3"C-70 were ...
Low-pressure rf plasma and corona decolourisation of indigo dyed denim fabrics
(Astronomical Observatory, Belgrade, 2008)
This study was aimed to investigate the influence of low-pressure RF plasma (gas, treatment time and power) and atmospheric pressure corona (number of passages and power) parameters on decolourisation of indigo dyed denim ...
Use of nonlinear frequency response analysis for model discrimination: Example - DMFC anode kinetics
(18th International Congress of Chemical and Process Engineering, CHISA 2008, 2008)
Nonlinear frequency response analysis is proven as a powerful tool for the characterization of nonlinear systems. A set of frequency response functions (FRF), which contain different information, is obtained. In a number ...
Comparison of different technologies for alginate beads production
(Springer International Publishing Ag, Cham, 2008)
This paper describes the results of the round robin experiment "Bead production technologies" carried out during the COST 840 action "Bioencapsulation Innovation and Technologies" within the 5th Framework Program of the ...
Temperature dependence of densities and excess molar volumes of the ternary mixture (1-butanol plus chloroform plus benzene) and its binary constituents (1-butanol plus chloroform and 1-butanol plus benzene)
(Springer/Plenum Publishers, New York, 2008)
Densities rho of the 1-butanol + chloroform + benzene ternary mixture and the 1-butanol + chloroform and 1-butanol + benzene binaries have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and ...
Electrochemical synthesis and characterization of hydroxyapatite powders
(Elsevier Science Sa, Lausanne, 2008)
Electrochemical synthesis of hydroxyapatite powders was performed galvanostatically from homogeneous solution of Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 at a concentration relationship Ca/EDTA/PO43- of 0.25/0.25/0.15 ...
Densities and excess molar volumes of the ternary mixture 2-butanol plus chloroform plus benzene and binary mixtures 2-butanol plus chloroform, or plus benzene over the temperature range (288.15 to 313.15) K
(Amer Chemical Soc, Washington, 2008)
Densities rho and excess molar volumes V(E) of the 2-butanol + chloroform + benzene ternary mixtures and two binaries, 2-butanol + chloroform and 2-butanol + benzene, have been determined. Experimental rho measurements ...
