Combination Chloride-Selective Microelectrode for Corrosion Study

Endoneural selective stimulating using wire-microelectrode arrays.

In acute experiments eight 5- to 24-wire-microelectrode arrays were inserted into the common peroneal nerve of the rat, to investigate whether the electrodes could selectively stimulate motor units of the extensor digitorum longus (EDL) muscle. Twitch-force-recruitment curves were measured from the EDL for each array electrode. The curves were plotted on a double-logarithmic scale and parameter...

Corrosion Behavior of Copper in Chloride Media

The electrochemical behavior of copper in 0.05 M HCl and 0.05 M NaCl carried out at open-circuit potential and at constant anodic potential after one hour has been investigated using electrochemical impedance spectroscopy (EIS) at 20 °C, 40 °C and 60 °C. The formation of copper chloride (CuCl) film does not protect copper from dissolution in the chloride media. The physical properties of the pa...

Selective Cloud Point Extraction for the Spectrophotometric Determination of Cetylpyridinium Chloride in Pharmaceutical Formulations

In this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (CPC) in pharmaceutical products using cloud point extraction (CPE) technique. The method is based on cloud point extraction of the CPC in alkali conditions using of nonionic surfactant Triton X-114. Under selected conditions, the calibration ...
