“…The CTAB surfactant in the microemulsion solution induces stabilizing and promoting the heme proteins (Nadzhafova et al, 2004;Nuthakki and Rusling, 2005). The Soret absorption of the aqueous composite made from 0.5 mM Mb and 0.1 mg ml −1 Zr(UMP) 2 ·H 2 O decreases by about 2% with the increasing the CTAB concentration from 0.00 mg ml −1 to 0.35 mg ml −1 .…”

A thin film of poly(L-serine) was prepared via electropolymerization for the determination of trace levels of estradiol. In pH 5.0 phosphate buffer, L-serine was oxidized during the cyclic potential sweeps between -0.60 and 2.0 V, forming a thin film at the electrode surface. The electrochemical behavior of estradiol was investigated. The oxidation peak potential of estradiol shifts negatively at the poly(L-serine) film-coated glassy carbon electrode (GCE) compared with that at the bare GCE. Otherwise, the oxidation peak current greatly increases at the poly(L-serine) film-modified GCE. These phenomena suggest that the poly(L-serine) film exhibits catalytic activity towards the electrochemical oxidation of estradiol. Based on this, a sensitive, rapid and simple electrochemical method was proposed for the determination of estradiol. The limit of detection is evaluated to be 2.0 9 10 -8 mol L -1 . Finally, this method was successfully used to determine estradiol in blood serum.

Electrochemical homolytic and heterolytic coupling of activated olefins in the absence and presence of benzyl bromide in microemulsion

Electrochemical reduction of four activated olefins namely cyclohexenone (CH), cyclopentenone (CP), methylmethacrylate (MMA), acrylonitrile (AN) in the absence and presence of benzylbromide (BBr) were investigated in CTAB/n-hexane/n-butanol/water based bicontinuous microemulsion (lE). Both cyclic voltammetric studies and galvanostatic preparative electrolysis were carried out. Cyclic voltammetric results in lE were also compared with those in N,N-dimehtylformamide (DMF) medium. Adsorption effects are observed both in DMF and lE. AN undergoes one electron reduction in aprotic solvent and two electron reduction in lE. CH, CP, BBr undergo one electron reduction and yield significant homolytic coupled products under galvanostatic conditions. AN and MMA lead to two electron reduction under identical conditions. In the presence of BBr, CH and CP alone yield significant heterolytic coupled products with simultaneous competitive resin formation. Reduction of AN leads to the formation of a identifiable quantity of propylamine and 3-phenylpropylamine in the absence and in the presence of BBr, respectively.
