A multiparametric sensor for cationic analysis

Effect of light irradiation on the gas sensor characteristics of the SnO2 and ZnO modified by tetrathiafulvalene derivative

“…In the region −2.0 V up to 0 V one can see ( fig. 1) two broad peaks (−1.66 and −1.80 V) describing the reduction of pyridine and thiophene fragments to form of stable anion and dianion radicals in course of process [36][37][38].…”
