“…A positive value of s signies the reaction is right symmetric, while a negative value of s signies the reaction is le symmetric. 58 S3 †), thermal decomposition of FO 11 in O 2 occurs in six overlapped steps in the 300-419 K, 332-465 K, 382-488 K, 439-545 K, 440-586 K and 515-635 K temperature ranges having T p values (averaged over heating rates) equal to ∼371 K, ∼420 K, ∼447 K, ∼488 K, ∼545 K and ∼573 K, respectively. Thus, as stated above, the rst three peaks (i.e., rst three steps) that appeared for FO 11 are due to decomposition of FcCHO and OxA in the O 2 atmosphere, whereas the last three peaks (i.e., last three steps) are for the thermal reactions leading to hematite.…”
