AbstractThe recently introduced photothermoelectric technique (PTE) was applied to detect first order phase transitions in some liquid thermoelectrics (LTE). The investigated samples were based on dodecanol mixed with tetradodecylammonium nitrate (TDAN) and tetrabutylammonium nitrate (TBAN). It was demonstrated that the Seebeck effect, produced by a LTE, is an useful tool for the detection of phase transitions in the very same material. Additional photopyroelectric (PPE) measurements suported the obtained results.
