Bakhuis Roozeboom Medal

Every four years, the Academy awards a medal to a researcher who has made a significant contribution to phase theory.

A group of scholars established the medal in 1911 in recognition of the work of the physicist and Academy member Prof. H.W. Bakhuis Roozeboom (1854-1907).  In 1992, various third parties – including Ms E.C. Bakhuis Roozeboom-Dros, the University of Amsterdam, and the Scheffer Fund (Delft University of Technology) – made donations to the existing Bakhuis Roozeboom Fund.

Phase theory is the science of the phase behaviour of matter under changing circumstances of pressure, temperature and composition. Phase theory can be applied in physical chemistry, physics, metallurgy, geochemistry, and astrophysics.

The laureate receives a medal engraved with the image of H.W. Bakhuis Roozeboom. The award ceremony will take place during a symposium focusing on the laureate’s research interest.
