Additional recommended knowledge
Derjaguin became famous in scientific circles for his work on the stability of colloids and thin films of liquids which is now known as the DLVO theory, after the initials of its authors: Derjaguin, Landau, Verwey, and Overbeek. It is universally included in text books on colloid chemistry and is still widely applied in modern studies of interparticle forces in colloids. In particular, the Derjaguin approximation is widely used in order to approximate the interaction between curved surfaces from a knowledge of the interaction for planar ones.
Derjaguin was also briefly (and embarrassingly) involved in polywater research during the 1960s. This field claimed that if water was heated then cooled in quartz capillaries, it took on astonishing new properties. Eventually, the scientists who were involved in polywater admitted it did not exist, claiming they were misled by poorly designed experiments.
