[Nanotechnology] – Spiral dislocation gives 3D topological photonics a robust edge
28 September 2022
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 been published in the journal Nature (“Photonic topological insulator induced by a dislocation in three dimensions”).
[Nonotech] – Nitrogen-doped porous carbon-supported catalysts boost conversion efficiency of carbon dioxide to carbon monoxide
20 January 2025
The ability to convert carbon dioxide into useful chemicals and fuels could help address rising atmospheric CO2 levels while simultaneously producing valuable industrial feedstocks.
