In September 2008, ONEXIM Group acquired 50% of Renaissance Capital, a major Russian investment bank which has reportedly encountered liquidity problems. ONEXIM purchased a small bank, renaming it IFC (for the bank which Prokhorov had run in the early 1990s). One of ONEXIM Group's divisions focuses on the development of nanotechnology investing in high-technology projects such as white LEDs. One of the key areas of development is the production of materials with ultra–tiny structures used in energy generation and medicine. As part of that focus, ONEXIM purchased Optogan in 2008.
