A novel synthesis of (3,6-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-9-(4-vinylbenzyl)-9H-carbazole), alternating polymer formation, characterization, and capacitance measurements
(Springer, 2013)
In this work, (3,6-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-9-(4-vinylbenzyl)-9H-carbazole) (EDOTVBCz) comonomer was chemically synthesized and characterized by Fourier transform infrared (FTIR), proton nuclear magnetic ...
Antioxidant and Tyrosinase Inhibitory Activities of Flavonoids from Trifolium nigrescens Subsp petrisavi
(Amer Chemical Soc, 2013)
Trifolium nigrescens was researched for its chemical constituents for the first time. Bioassay-guided isolation of the EtOAc extract from the leaves of T. nigrescens resulted in the purification of a new biflavone, 4',5,5 ...
A Novel Biosensing System Using Biological Receptor for Analysis of Vascular Endothelial Growth Factor
(Springer, 2014)
An immunosensor with rapid and ultrasensitive response for vascular endothelial growth factor (VEGF) has been built up with 4-aminothiophenol (4-ATP) onto the gold surfaces. Quantitative analysis of VEGF was performed by ...
Electrochemical copolymerization of N-methylpyrrole and 2,2 '-bithitiophene; characterization, micro-capacitor study, and equivalent circuit model evaluation
(Indian Acad Sciences, 2013)
N-methylpyrrole (N-MPy) and 2,2'-bithiophene (BTh) were electrocopolymerized in 0 center dot 2 M acetonitrile-sodium perchlorate solvent-electrolyte couple on a glassy carbon electrode (GCE) by cyclic voltammetry (CV). The ...
Amperometric Biosensor for Xanthine Determination Based On Fe3O4 Nanoparticles
(Slovensko Kemijsko Drustvo, 2014)
An amperometric xanthine biosensor was developed based on the immobilization of xanthine oxidase (XO) into the Fe3O4 nanoparticles modified carbon paste. Electron transfer properties of unmodified and Fe3O4 nanoparticles ...
Comparison of electrolyte effects for poly(3,4-ethylenedioxythiophene) and poly(3-octylthiophene) by electrochemical impedance spectroscopy and polymerization parameters with morphological analyses on coated films
(Springer, 2013)
3,4-Ethylenedioxythiophene and 3-octylthiophene were electropolymerized on glassy carbon electrodes (GCE) to compare with four different electrolytes [lithium perchlorate (LiClO4), sodium perchlorate, tetraethylammonium ...
