the effect of mentha spicata l. extract on the corrosion behaviour of carbon steel in 1.0 m hcl solution was investigated using polarization, electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques. the solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (ie). the effect of temperature on the rate of corrosion ...

Silicon materials remain unused for supercapacitors due to extreme reactivity of silicon with electrolytes. However, doped silicon materials boast a low mass density, excellent conductivity, a controllably etched nanoporous structure, and combined earth abundance and technological presence appealing to diverse energy storage frameworks. Here, we demonstrate a universal route to transform porous...

Scanning Electrochemical Microscopy is a tool for imaging and investigate surfaces by meaning of chemical reactivity, electric conductivity, and enzymatic activity. This technique is typical electrochemical cell plus three axis positioner. Positioner allows to measure typical electrochemical measurements, like Cyclic Voltammetry, Chronoamperometry, Impedance Spectroscopy, etc. in the vicinity o...

Robust composite nanofibers (NFs) are prerequisite for highly efficient electrochemical sensors. We report the electrochemical application of gold nanoparticle (Au NP)-composite Nafion NFs using a facile electrospinning technique. Owing to the uniform distribution and large surface area of the Au NPs in the NFs, the Au NP-composite electrodes gave rise to greatly improved electrochemical proper...

In this study, yttrium aluminum garnet (YAG) was prepared using a facile electrochemical technique. Four samples were synthesized in 0, 20, 40 and 60°C by electrochemical pulse deposition and were then calcined at 1200°C. The effect of synthesis temperature on morphology and structure of YAG was studied using X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron micro...

Measuring electrochemical activities of nanomaterials is critical for creating novel catalysts, for developing ultrasensitive sensors, and for understanding fundamental nanoelectrochemistry. However, traditional electrochemical methods measure a large number of nanoparticles, which wash out the properties of individual nanoparticles. We report here a study of transient electrochemical oxidation...

A novel electrochemical sensor was proposed for the determination of amitriptyline based on the copper oxide (CuO) nanoparticles modified graphite screen-printed electrode. CuO nanoparticles were used to enhance the surface area of the electrode and then improve the sensitivity of the electrochemical sensor. Amitriptyline electrochemical response characteristics of the modified electrode in a p...
