Fig. 7: Schematic diagram showing the pathways of microdroplet-induced interactions between alkane and water at elevated temperatures.

Step-1 represents the formation of water microdroplets in the alkane phase; step-2a represents the formation of water-derived free radicals based on the water microdroplets; step-2b represents the formation of alkane-derived free radicals; step-3 represents the recombination of different free radicals to form different species.
