Paper-like mirrors

Chiral Mirrors

Conventional mirrors convert right-handed circularly polarized waves (RCP) into left-handed circularly polarized waves (LCP) and vice versa, see Fig. 1(a-c). Here we demonstrate a novel type of chiral mirror that will reflect one circular polarization without changing its handedness, while absorbing waves of the opposite handedness, see Fig. 1(d-f). This functionality, which fundamentally relie...

Brain organization mirrors caste differences, colony founding and nest architecture in paper wasps (Hymenoptera: Vespidae).

The cognitive challenges that social animals face depend on species differences in social organization and may affect mosaic brain evolution. We asked whether the relative size of functionally distinct brain regions corresponds to species differences in social behaviour among paper wasps (Hymenoptera: Vespidae). We measured the volumes of targeted brain regions in eight species of paper wasps. ...

Displaying Digital Information on Paper-like Devices

Microfluidics for electronic paper-like displays.

Displays are ubiquitous in modern life, and there is a growing need to develop active, full color, video-rate reflective displays that perform well in high-light conditions. The core of display technology is to generate or manipulate light in the visible wavelength. Colored fluids or fluids with particles can be used to tune the light intensity (greyscale) or wavelength (colors) of reflective d...
