21_11i/2011Bijel Capsules: Novel, Robust, and Versatile Bijels of Nitromethane, Ethanediol, and Colloidal Silica: Capsules, Sub-Ten-Micrometer Domains, and Mechanical Properties (Adv. Funct. Mater. 11/2011)

Bicontinuous, interfacially jammed emulsion gels (bijels) are a class of soft solid materials in which interpenetrating domains of two immiscible fluids are stabilized by an interfacial colloidal monolayer. Bijel capsules, as presented by Joe W. Tavacoli and co-workers on page 2020, may find application in controlled release. They contain bicontinuous liquid domains where internal and external interfaces are stabilized by (different) colloidal particles. The image shows a fluorescence confocal microscopy image of such a capsule.
