An electroactive material suitable for electrochemical cell electrode wherein the electroactive material includes a chalcogen oligomer that can reversibly deintercalate/reintercalate an anion of the chalcogen, such as LaOS, and the electrochemical electrodes and cells containing the electroactive material.

Electrochemical cells based on intercalation and deintercalation of chalcogen anions

Provided is a non-stick coating including at least one functional decorative layer, including a pigment composition having a reversible variation of optical and/or colorimetric properties when the coating is subjected to a temperature variation between a cold temperature of 0&#xb0; C. to 40&#xb0; C. and a hot temperature of 80&#xb0; C. to 400&#xb0; C. The pigment composition includes at least one compound of formula YMFeQOin the form of particles, in which M is selected from the lanthanides, alkaline metals, alkaline-earth metals and metalloids with a degree of oxidation (DO) +3; Q is selected from the group made up of the lanthanides, non-metals with degree of oxidation +4, metals with DO +3 or +4, transition metals with DO +2 or +4, alkaline-earth metals and alkaline metals; and wherein x is between 0 and 0.3 and y is between 0 and 3.
