Only the blue absorbance is used for measurement of flavan product formation. Resistance heating and microprocessor control as shown in Fig. 2 are used to bring the temperature of the sample cell to the 60 °C reaction temperature. A small pump provides a dry air purge which could be ...
(I) retention of the catalytic activity on repeated reaction and the absence of a limiting yield; (2) higher activity than that of a conventional poly(styrenesulfonic acid) resin; (3) virtual absence of solvent effects on the reaction rate and the product composition; and (4) formation of ...
Nafion byproduct 2 (NBP2) is a polyfluoroalkyl ether sulfonic acid that was recently detected in surface water, drinking water, and human serum samples from monitoring studies in North Carolina, USA. We orally exposed pregnant Sprague-Dawley rats to NBP2 from gestation day (GD) 14–18 (0.1...
Therefore, we propose the following process: the solubility of ODB in the casting solution decreases with increasing water content by evaporation of ethanol and n-propanol, leading to phase separation of Nafion solution and ODB. Due to the high density of Nafion (Nafion: 1.97 g/ml, Nafion ...
The difference in wettability between the electrospun silica/Nafion hybrid product and bulk aqueous sol could be caused by the molecular orientation of Nafion during the electrospinning process. The hydrophobic behaviour, improved mechanical performance and good thermal stability made the silica/Nafion ...
Nafion/lead-ruthenium oxide pyrochlore (Pb2Ru1.75Pb0.25O7– y ) chemically modified electrode (NCME) exhibits excellent electrocatalytic response towards the norepinephrine (NE) oxidation reaction. NE oxidation by CV studies show the following main features: i) electrochemical oxidation of NE to o...
Potential step chronoamperospectrometry (PSCAS) was carried out to analyze electron transfer in the redox reaction processes of 5,10,15,20-tetraphenylporphyrinatocobalt(II) (CoIITPP(2)) incorporated in a Nafion film. The reactions of CoIITPP(2) to [CoIIITPP(2)]+ and of [CoIIITPP(2)]+...
