word of the day: electrostriction

The word of the day is electrostriction:

n. chiefly Physics change in the volume or shape of a substance, esp. a dielectric, resulting from the application of an electric field. (OED)

"With these approximations the following equation was derived... where Vi is the partial molal volume of the apolar part of the monomer, (Vs-vs) equals the electrostriction of the electrolyte in solution and beta0 is the compressibility of water at temperature T."

 - Tausk et al., "Physical chemical studies of short-chain lecithin homologues.  I.  Influence of the chain length of the fatty acid ester and of electrolytes on the critical micelle concentration", Biophysical Chemistry 1:175 (1973)
