Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

Advanced Materials, EarlyView.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.

Switching properties in Siloxane-based Liquid-crystal Elastomer [PDF]

, 2010
Mechanical and X-ray scattering measurements on a side-chain liquid-crystal elastomer based on a Siloxane backbone are presented. The application of a stress field to the elastomer while in the nematic phase result in a stress-induced alignment of the ...

Dynamic Theory of Polydomain Liquid Crystal Elastomers

Physical Review Letters, 2015
When liquid-crystal elastomers are prepared without any alignment, disordered polydomain structures emerge as the materials are cooled into the nematic phase. These polydomain structures have been attributed to quenched disorder in the cross-linked polymer network.
