Francesca Serra, Shane Michael Eaton, Roberto Cerbino, Marco Buscaglia, Giulio Cerullo, Roberto Osellame and Tommaso Bellini Liquid Crystals: Nematic Liquid Crystals Embedded in Cubic Microlattices: Memory Effects and Bistable Pixels (Adv. Funct. Mater. 32/2013) Advanced Functional Materials 23
S. M. Eaton and co-workers report the first experimental proof of the bistability of nematic liquid crystals incorporated in a porous network with a controlled geometry. This configuration, described in detail on page 3990, is specifically designed to enhance memory effects by inducing a regular arrangement of topological defects. The cover image shows this three dimensional porous network, fabricated by femtosecond laser lithography, with the incorporated liquid crystals. This composite material could be exploited for future ultralow-power bistable displays.
