svedberg

svedberg
(S)
   a unit equal to 10-13 second (0.1 picosecond), used to measure sedimentation coefficients in ultracentrifuge technology. The sedimentation coefficient of a particle is defined to be s/(w2r), where s is the sedimentation rate, w is the angular velocity of the centrifuge (in radians per second), and r is the radius at which the particle is being spun; this calculation gives a quantity in time units. The unit honors the Swedish chemist Theodor Svedberg (1884-1971), who received the Nobel Prize in Chemistry for 1926 for the invention of the ultracentrifuge and its use in studying the properties of colloids.
