Electrochemical synthesis of poly-3-aminophenylboronic acid in sulfuric acid solution

Sensors based on the complexation of boron groups with diols are an attractive alternative to detection of biologic compounds in particular dopamine. The electropolymerisation of 3- aminophenylboronic acid (APBA) in aqueous solutions on Pt electrodes has been investigated. The obtained poly-3-aminophenylboronic acid is used for the potentiometric detection of dopamine

Anticorrosion property of vinylphosphonic acid-co-diethylvinylphosphonate copolymers obtained by UV curing

Copolymers of vinylphosphonic acid (VPA) with diethylvinylphosphonate (DEVP) at different molar ratio from 1:1 to 4:1 were synthesized by using ultraviolet light. The polymers are soluble in water. They are investigated as corrosion inhibitors for iron by using impedance spectroscopy. The best result regarding the anticorrosion property was obtained for copolymer VPA:DEVP 1:1, with an inhibition efficiency of 72%

Lithium doped polyphosphoester composite

The effect of lithium triflate on the ionic conductivity of polyphosphoester composite was investigated by electrochemical impedance spectroscopy (EIS). The highest conductivity was obtained for membrane with 15% lithium salt. The ion transport is slow due to the aggregation tendency of ions for composite membrane with higher than 20% lithium salt. The conductivity of all membranes increases linear with the increase of the temperature and shows a thermally activated process

An EIS and UV-Vis Spectroscopy Assay for Aggregation of Monoazo Acid Dye

The qualitative and quantitative analysis of the aggregation of monoazo acid dye (I) (sulfanilic acid → phenol) has been studied by UV-Vis spectroscopy and electrochemical impedance spectroscopy (EIS
