The field of thermoelectrochemistry has experienced a revival through a new direction commonly characterized as active thermoelectrochemistry. Prominent terms are, e.g., heated electrodes, hot-wire electrochemistry, sonoelectrochemistry or microwave electrochemistry. In all these new methods, temperature is used intentionally as an active parameter in an analogous manner to voltage or current.
Active thermoelectrochemistry does not mean just warming up or cooling down an electrochemical cell to study something at varied temperatures. Instead, localized regions in cells are preferred objects; consequently, non-isothermal cells are utilized. Electrodes are heated by Joule heat, by microwaves, by laser, or by friction. Further, heat is transferred in both directions by means of Peltier elements. Typically, localized regions with forced temperature inside non-isothermal electrochemical cells are the subject of investigations.
Heated or cooled electrode surfaces inside classical cells may provide results which otherwise would not be available. Volatile or unstable substances can be analyzed at increased temperatures without damaging the bulk content, and superheated water in local spots can be used as an ordinary solvent. Stripping analysis has been greatly improved this way, and electrochemoluminescence has proven successful at heated electrodes. Even a hot-tip electrode for SECM seems to be possible.
You are kindly invited to contribute to this Special Issue.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
