To try to develop a more sensitive probe for isolating individual peptides — short strands of amino acids — from a pool of similar molecules, a team led by chemist Clark Still of Columbia University 4 years ago synthesized small organic compounds that selectively fish out peptides dissolved in chloroform.

In the study, researchers used the blood of seven people who survived Ebola Bundibugyo virus infection during the 2007 outbreak in Uganda to isolate a large number of B cells that produce antibodies, which are the small protein molecules capable of inactivating the virus.

Using a technique called COSMIC (Crosslinking of Small Molecules to Isolate Chromatin), the researchers were able to create polyamides that would bind to DNA in human embryonic stem cells.

In 1996, Schreiber used small molecules to characterize the molecular nature of histone deacetylases (HDACs) for the first time — before this work, HDAC proteins had not been successfully isolated.

I'm not sure offhand of the importance of this, but more rapid cooling from more rapid ascent would reduce the distances over which molecules can diffuse during the time periods involved, which would tend to isolate the effects of the particles from each other, so that more haze particles could go on to become cloud droplets, resulting in smaller and more numerous cloud droplets.
