  • Professor Boris Vladimirovich Derjaguin (or Deryagin) was one of the renowned Soviet/Russian chemists of the twentieth century. As a member of the Russian Academy of Sciences he laid the foundation of the modern science of colloids and surfaces. An epoch in the development of the physical chemistry of colloids and surfaces is associated with his name. 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. He is also known for having hotly rejected some of the then-new ideas of adhesion as presented by the Western block in to 1970's. His model came to be known as the DMT (after Derjaguin, Muller and Toporov) model, and the model presented by the then Western bloc, came to be known as the JKR (after Johnson, Kendall and Roberts) model for adhesive elastic contact. This rejection proved to be instrumental in the development of the Tabor and later Maugis parameters that quantify which contact model (of the JKR and DMT models) represent adhesive contact better for specific materials.
  • Борис Владимирович Дерягин — русский физикохимик, профессор (1935), член-корреспондент АН СССР (1946), академик РАН (1992). Создал учение о поверхностных силах и их влиянии на расклинивающее давление и свойства тонких жидких пленок. Премия им. М.  В.  Ломоносова АН СССР (1958), Государственная премия СССР (1991). С 1936 по 1994 год возглавлял созданные им лабораторию и Отдел сорбционных процессов Института физической химии АН СССР. Много лет был главным редактором журнала «Коллоидной химии». В 1962—1973 гг. предполагал существование особой разновидности воды — поливоды. Потом сам себя опроверг, обнаружив критическое влияние примесей — силикатов.
