A printed hexagonal monopole antenna fed by a coplanar wave-guide has been presented for ultra wide bandwidth. Parametric study of hexagonal configuration with vertex feed arrangement has been carried out to study the effect of feed gap on bandwidth. Experiments have been performed to measure, bandwidth and radiation patterns of this printed monopole(More)
The electrochemical behavior of quinine was investigated by cyclic voltammetry (CV) and square wave voltammetry (SWV) using surfactant. The reduction peak current of quinine increases remarkably in presence of 1% CTAB. Its electrochemical behavior is quasi-reversible in the Britton-Robinson buffers of pH 10.38 by exhibiting the well-defined single cathodic(More)
Herein, a new electrochemical method was described for the determination of atropine based on the enhancement effect of an anionic surfactant: sodium dodecyl benzene sulfonate (SDBS). In pH 10.5 tetramethyl ammonium hydroxide as supporting electrolyte and in the presence of 0.4×10(-4)M SDBS, atropine yields a well-defined and sensitive oxidation peak at the(More)
In the past two decades chemically modified electrodes (CME) have attracted considerable interest of researchers to exert a direct control over the chemical nature of electrodes. CMEs have found a large number of useful applications in different fields viz. selective electroorganic synthesis, biomedical analysis, electro analyses etc. The ability to(More)
