Negative-stain TEM micrographs of extracted fatty acids in aqueous solution. (A) Spherical structures obtained from fatty acid forming reaction mixtures containing acetylene, CO and NiS after solvent extraction, drying and resolubilisation in water. (B) TEM micrographs from identical experiments to A with argon instead of acetylene and CO, a setup which shows no fatty acid formation. The scale bar represents 100 nm in all micrographs.
