Angle-dependent holograms made possible by metasurfaces

Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurfaces to fabricate angle-dependent holograms with multiple functions. This technology allows holograms to display multiple ...

A novel technique for creating superhydrophobic surfaces

Superhydrophobic surfaces, characterized by their ability to repel water with a contact angle above 150° and a sliding angle below 10°, offer a range of applications from self-cleaning and anti-corrosion to oil/water separation ...

Structural color ink: Printable, non-iridescent and lightweight

A new way of creating color uses the scattering of light of specific wavelengths around tiny, almost perfectly round silicon crystals. This Kobe University development enables non-fading structural colors that do not depend ...
