Electrochemical Techniques

The conversion of CO2 into valuable raw materials like methanol is an important pillar for a sustainable economy, with the enzyme formaldehyde dehydrogenase (FaldDH) often playing a key role.

In this application note, we introduce the reader to a pulsed electrochemical deposition technique and how electrochemical quartz crystal microbalance (EQCM) can provide additional insight into the processes that occur during each of its cycles.

Among the many electrochemical techniques available in Gamry Instruments’ Framework™ software is square-wave voltammetry (SWV), a form of pulse voltammetry. SWV is typically used in sensing electrochemically-active analytes present at low concentration. SWV, like other pulsing techniques (differential pulse, normal pulse, etc.) is more sensitive than cyclic voltammetry because the pulse current is subtracted from a baseline current to generate a differential current.

This application note outlines an electrochemical method using cyclic voltammetry (CV) to detect iron (Fe) impurities in aqueous alkaline electrolytes using nickel (Ni) electrodes. The performance of Ni electrodes towards the oxygen evolution reaction (OER) is not the focus.

Ion channels and pores facilitate the transport of inorganic and organic molecules across lipid bilayers without displacing themselves or disrupting the membrane's suprastructure.

Cyclic voltammetry (CV) is a useful technique for extracting qualitative kinetic data from an electrochemical reaction.
