Summary: The low-temperature oxidation spontaneous combustion of coal is caused by the active groups in its structure. The form and content of organic sulfur in coal play a significant role in the tendency of coal spontaneous combustion. The oxidation of coal is related to the content and type of organic sulfur, as well as the presence of oxygen-containing groups. The reactivity of mercaptans is higher than that of thiophenes in the low-temperature region during oxidation reactions.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
