‘Screw this!’ – Spiral dislocation gives 3D topological photonics a robust edge
Sep 28, 2022 (Nanowerk News) Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering. Their discovery has recently...
Biosensor detects brain tumors with less than a drop of blood
Sep 28, 2022 (Nanowerk News) Despite significant advances, mortality from brain tumors remains high with five-year survival rates of 36%, according to the National Cancer Institute. More accurate diagnoses might improve the situation, but tissue biopsies are invasive and can miss important information about a tumor’s make-up. Imaging-based methods, meanwhile,...

Metasurface creates different images depending on illumination
Sep 27, 2022 (Nanowerk News) Researchers have developed a metasurface device that can display three types of images depending on the illumination light. The three-channel device could be used as an anticounterfeiting measure or offer a new way to securely deliver encrypted information. Researchers have developed a metasurface device that...
A powerful Bragg reflector made with ultrahigh refractive index metamaterial
Sep 27, 2022 (Nanowerk News) We all look in the mirror at least once a day to see our reflection. Mirrors are used not only in daily life but also in cutting-edge technologies such as semiconductor processing and high-resolution displays. Recently, a powerful Bragg reflection mirror based on high-index metamaterials...
Quantum effects in memristive devices
Sep 27, 2022 (Nanowerk News) At the nanoscale, the laws of classical physics suddenly become inadequate to explain the behavior of matter. It is precisely at this juncture that quantum theory comes into play, effectively describing the physical phenomena characteristic of the atomic and subatomic world. Thanks to the different...
