Chronoamperometric study of conformational relaxation in PPy(DBS).
In conjugated polymer devices that switch from one oxidation level to another, such as artificial muscles, it is important to understand memory effects that stem from conformational relaxation movements of the polymer chains. Chronoamperometry during electrochemical switching of polypyrrole doped with dodecylbenzenesulfonate, PPy(DBS), is used to gain insight into the conformational relaxation ...
متن کاملSupporting Information for Chronoamperometric Study of Conformational Relaxation in PPy(DBS)
The effect of the working electrode surface must be considered in this type of study, since it is thought to strongly influence the kinetics of relaxation [1]. The ESCR model was developed based on experimental data obtained from PPy films deposited on polished Pt. In those (anion-transporting) systems, nucleation was observed in the form of expanding cylinders that coalesced over time (visible...

پیدایش مرحله ی جدیدی از نظام سرمایه داری بعد از جنگ جهانی دوم همزمان است با ظهور عصر اطلاعات و رسانه جمعی. در چنین جامعه ای سیر آزادانه ی نشانه ها در فضای بی اساس مجازی بر سرعت فرسایش واقعیت می افزاید. به اعتقاد بودریار، فقدان واقعیت به واسطه ی شبیه سازی آن و تولید حاد واقعیت (hyperreality) پنهان خواهد ماند. این پژوهش بر آن است که جامعه فرانوین توصیف شده در سه رمان بریان مور را با توجه به نظر...
15 صفحه اولChronoamperometric Study of Bisulfite Reduction by Myoglobin
The kinetics of the reduction of bisulfite by surfactant myoglobin films were examined using chronoamperometry after the overall stoichiometry of the reduction was examined by coulometry. Surfactant films of myoglobin were formed on a graphite (HOPG) electrode. On this electrode, two waves were observed for myoglobin, corresponding to the Fe(III)/Fe(II) and Fe(II)/Fe(I) reductions. Cyclic volta...
