Abstract:
Oxidation of aniline in aqueous solution by ·OH radicals proceeds predominantly via addition to the ring followed by elimination of OH- on the microsecond time scale to form the aniline radical cation. Direct oxidation by electron transfer accounts for less than 4% of the ·OH reactions. The different hydroxycyclohexadienyl isomers produced by ·OH addition decay at different rates with this decay catalyzed both by protons and phosphate. In basic solution the resultant radical cation deprotonates to form the anilino radical. The p Ka for the equilibrium between the acidic and basic forms of this

Para a caracterização das propriedades ópticas não lineares foram utilizadas as técnicas de varredura-Z resolvida em freqüência e com trem de pulsos.

The physical properties of aforementioned composites are significantly changed by the doping with HCl, H2SO4, HNO3, H3PO4, or acrylic acid. The charge transport properties of these polymeric materials have been studied in detail because of their potential application in gas sensors.

TiO2 has excellent photoelectrochemical properties, which makes its suitable for photoanode applications. TiO2 is widely utilized as semiconductor for dye-sensitized photoanode owing to its excellent stability and availability. The brookite polymorph of TiO2 has been suggested to demonstrate better photocatalytic properties. In this work, we studied the adsorption of polyenediphenyl-aniline dyes on (TiO2) n = 8, 68 brookite clusters using density functional theory (DFT).

Abstract:
Photon correlation spectroscopy (PCS) is the most precise and accurate method to measure a size of submicron particles in transparent suspensions. However, interpretation is simple only for single scattering approximation and much more complicated for multiple scattering. For dark "non-transparent" media, such as a crude oil, metal powder suspensions, etc… PCS technigue is practically not usable. In such media the multiple scattering is negligible due to the strong light absorption. Low-optical-path cells are not convenient in practice.

Brinase, a proteinase from Aspergillus oryzae, has previously been shown to have a significant thrombolytic effect in patients suffering from peripheral arterial disease. Brinase is rapidly bound to α1-proteinase inhibitor and α2-macroglobulin (α2M) in plasma. Since binding of a proteinase to α2 M only results in ste-rical blockingof the active siteand not complete inactivation of the enzyme, it has been suggested that brinase in complex with α2M may retain ability to digest fibrin.To test this hypothesis, we have characterized the binding of brinase to α2M and the properties of the complex fo
