In this work, a novel pseudo triple-enzyme cascade catalysis amplification strategy was employed to fabricate a highly sensitive electrochemiluminescence (ECL) aptasensor for thrombin (TB) detection. The signal amplification of the proposed aptasensor was based on the synergistic catalysis of glucose dehydrogenase (GDH) and hemin/G-quadruplex to generate a co-reactant in situ for the ECL of per...

1,4-bis(triphenyl phosphonium)butane peroxodisulfate(BTPPBPDS) were synthesized by treating 1,4-bis(triphenyl phosphonium)butane dibromide and potassium peroxydisulfate in aqueous solution.This was used mild and efficient reagent for oxidation of alkyl benzenes to their corresponding carbonyl compounds in very good to high yields.

oxidation of methyl orange (mo) solution in potassium peroxydisulfate (kps) homogeneous reaction system without uv irradiation was investigated. the result shows that decolorization of mo increases as the dosage of k2s2o8 increases. the kinetic results demonstrate that the decolorization reaction is a pseudo first-order reaction when the concentration of mo is below 10 mg/l and langmuir–hinshew...

Abstract. The progress of the oxidative polymerization of aniline with ammonium peroxydisulfate in aqueous medium has been monitored in situ by attenuated total reflection Fourier transform infrared spectroscopy. The growth of polyaniline film at the crystal surface as well as changes proceeding in the surrounding aqueous phase is reflected in the spectra. It has been shown that in aqueous solu...

Reduced graphene oxide (rGO) was applied to prepare various composites of rGO/photocatalyst of G/TiO2, G/ZnO and G/Ta2O5, using titanium (IV) isopropoxide, Zn powder and commercial Ta2O5 powder as photocatalyst precursors, respectively. X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric-differential t...
