A paper demonstrating that an enthalpy–entropy compensation relationship holds in thermocells has been published in JACS.

This is a collaborative study with Professor Ando of the Faculty of Science at Yamagata University and Professor Matsumoto of the Graduate School of Energy Science at Kyoto University.

Our peper on Electrochemical Peltier (ECP) cooling is published in Small Methods as Editor’s Choice

Electrochemical Peltier Cooling: Device Design, Measurement Techniques, and Molecular Optimization

Electrochemical Peltier (ECP) cooling uses the entropy change to transfer heat. In comparison to air conditioners, which cool down the entire space, the ECP cooling cools down only the part where the electricity is applied and is useful for localized cooling. In addition, the ECP cooling can tranfer heat efficiently by flowing the electrolyte while applying the electric current.
