Dear Colleagues,

Heated electrodes for use in non-isothermal cells provide convenient means for studies in the field of thermoelectrochemistry. Both the electrode body and the adjacent electrolyte layers can be heated by electric current, microwaves, or intense light. After a few attempts by others between the 1960s and the 1980s regarding joule-heating of electrodes, the group of Peter Gründler at the University of Rostock published numerous articles since 1993 on a new approach; the symmetrical directly heated electrode. This was a breakthrough for this technique for both fundamental studies and analytical applications. Shortly after, Gründler et al. introduced the novel technique of Temperature-Pulse-Voltammetry that allows for voltammetric studies at electrode temperatures far above the boiling point of the electrolyte. Several other groups have published numerous papers on both directly and indirectly heated electrodes pointing out the various advantages including acceleration of sluggish electrode processes, intensified mass transport and micro-stirring effects, thermal regeneration of sensors coupled with self-cleaning effects, and finally ultra-fast electrode temperature changes in temperature pulse techniques. Latest developments include even super-cooled electrodes.

The Special Issue on “Thermo-Electrochemical Sensors” considers all papers that deal with temperature effects in electrochemical sensing approaches.

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 submissions that pass pre-check are 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. Sensors 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 2600 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.
