Batteries Catalysts Coatings Corrosion SECCM SMCM

Holiday reading

While spending some time outside the lab to recover and enjoy the holiday season, why not have some reading material at hand?

We collected some recent articles on scanning micropipette techniques which are gaining increasing popularity at the moment.

With scanning micropipette techniques, the local electrochemistry of your sample can be studied. A micropipette is filled with electrolyte to form a small droplet at the opening. This droplet is brought into contact with the sample and forms a miniaturized electrochemical cell. This way, common bulk electrochemical experiments can be performed on the micron scale with spatial resolution. Polpular applications are the study of corrosion, coatings, battery materials and (photo)catalysts.

These scanning techniques are commonly called either scanning electrochemical cell microscopy (SECCM) or scanning micropipette contact method (SMCM) and might employ either double-barrel or single barrel micropipettes. If the micropipette is not scanned in a regular pattern, but rather moved to specific spots to collect local data, the technique is also just called micropipette contact method.

We wish you a successful end of the year and a good start into the next one!
