It is found that a micrometer-sized droplet in an aqueous solution of binary polymers [water/polyethylene-glycol (PEG)/dextran] disappears upon irradiation with a focused yttrium-aluminum-garnet laser. The interface of the dextran-rich droplet broadens and disappears, and it reappears upon turning the laser off, whereas the PEG-rich droplet shrinks and disappears. These phenomena are discussed in terms of the free energy by considering the laser-induced dielectric potential.
We have developed a thinnest QD film with honeycomb structure which can prevent edge deterioration when cut into various shapes. The honeycomb structure protect oxygen invasion from the edge, and also enhances stiffness of thin film. This QD film can be applied to narrow-bezel and thin displays and free-form displays.
We have successfully developed a novel brightest transparent screen using diffraction and scattering of light by tilted cholesteric liquid crystals suit for rear‐projection. It controls the direction of projector light to realize both high transparency and brightness. We expect that it could expand AR imaging applications for stores and vehicles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
