## Abstract Nine isomeric cyanobiphenylβsubstituted (25%) polymethylsiloxane (CBP) stationary phases were coated and immobilized by freeβradical crosslinking on silica packing materials for use in supercritical fluid chromatography (SFC). The selectivities of these packing materials to benzene deri

High nitrile content cyano-substituted polymethylsiloxane encapsulated particles were prepared for double bond selectivity in packed capillary column supercritical fluid chromatography (SFC). Silica particles were deactivated with 50% cyanopropyl-substituted polymethylhydrosiloxane, and coated with
## Abstract **Summary:** A simple method to prepare surfactantβfree and solventβfree semiconducting polymer particles by using an environmentally benign supercritical carbon dioxide (scCO~2~) process is reported. The process of the rapid expansion of supercritical solutions (RESS) is used to produc
