Cholesteric liquid crystal shells provide omnidirectional reflection with selectivity in wavelength and polarization. By tuning the reflection wavelength from the infrared to the ultraviolet, via the visible, numerous applications can be envisaged, as summarized by Mathew Schwartz, Gabriele Lenzini, Jan P. F. Lagerwall, and co‐workers in article number 1707382. These applications range from tokens...
The responsive and dynamic character of liquid crystals (LCs), arising from their ability to self‐organize into long‐range ordered structures while maintaining fluidity, has given them a role as key enabling materials in the information technology that surrounds us today. Ongoing research hints at future LC‐based technologies of entirely different types, for instance by taking advantage of the peculiar...
