TL;DR: In this paper, the electrochemical oxidation of ammonia was studied at room temperature on a black platinum electrode, iridium black, a mixture of both and PtIr electrodeposits in alkaline solutions of potassium hydroxide.

TL;DR: The highest yield (14.4 g/kg) of naringin, the major flavonoid from the peel of Citrus paradisi L., that could be achieved by supercritical fluid extraction was obtained using supercritical carbon dioxide modified with 15% ethanol and fresh peels at 95 bar and 58.6 degrees C.

TL;DR: In this article, the results of cyclic voltammetry and differential electrochemical mass spectrometry (DEMS) were compared with pure Pt. The results confirmed Pt-Ir alloys as alternatives to Pt electrodes concerning ammonia oxidation, with the less compact planes the more affected ones.

TL;DR: In this paper, the X-ray diffraction, Auger electron spectroscopy, and Xray photoelectron spectrographs were used to characterize platinum-ruthenium deposits.

TL;DR: In this article, the reduction-oxidation processes and conducting properties of manganese dioxide films prepared by electrochemical deposition on Pt substrate were studied in borate/boric acid solutions using electrochemical impedance spectroscopy (EIS).
