Short summary
The formation of cloud droplets involves the condensation of water onto preexisting particles in the atmosphere. The efficiency of this process depends on the nature of the particles, and recent work has shown that organic-rich particles may exhibit a suppressed surface tension that promotes the formation of cloud droplets. In this technical note, we discuss the mechanism for this and highlight the evolution of surface tension as the key factor in the extent of surface effects.
