A rapid isocratic method of high performance liquid chromatography system (HPLC) with a glassy carbon working electrode of electrochemical detector is set up for quantitative detection of  trace amount of nitrite ion (NO2¯) in aqueous protein containing cell lysate, cell media, plasma, serum, urine and other body fluids. The solid extraction  reversed phase cartridges ...

vanillin offers interesting possibilities for corrosion inhibition because of its safe use and highsolubility in water. the effect of vanillin on the corrosion inhibition of aisi 304 stainless steel in0.5m h2so4 solution has been studied using potentiodynamic polarization and electrochemicalimpedance spectroscopy (eis). furthermore, this paper demonstrates that the electrochemical noise(en) tec...

The rapid development of wearable and portable electronics has resulted in an urgent desire for lightweight, flexible microsystems integrated with energy storage devices other in-plane devices. An approach is proposed herein to develop microsystem on graphite paper containing all-solid-state microsupercapacitor a photoconductor-type photodetector based perovskite film, where simple, low-cost, s...
