Abstract:

The aqueous electrochemistry of a number of anthraquinone derivatives was studied by using cyclic voltammetry at the surface of carbon paste electrode (CPE). From measurements of the half-wave potential as a function of pH, the potential - pH diagrams were constructed for each compound. The values of formal potentials and the pK'a of some different redox and acid-base couples involved in each compound at various pHs were obtained.

the effect of consciousness raising (c-r) on the reduction of translational errors: a case study

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...

Alumina nanoparticles modified carbon paste electrode as a new voltammetric sensor for determination of dopamine

The present study examines a new dopamine sensor based on Alumina nanoparticles modified carbon paste electrode (Al2O3NPsCPE). Moreover, the present study focuses on the electrochemical act of the Al2O3NPsCPE for the detection of dopamine by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). There is also a focus on the specification of the prepared modified electrode by electroc...
