General description

Electrophoretic mobility of polymethylmethacrylate (PMMA) particles in a low-polar, density- and refractive-index-matched mixture of cyclohexylbromide and cis-decahydronaphthalene was investigated. cis-decahydronaphthalene (cis-DeHN) undergoes zeolite-catalyzed conformational isomerization to trans-DeHN.
