Photonic skyrmions discovered
Skyrmions, ‘hedgehogs’ of electron spins, are well known in magnetic materials and were long considered for applications in spintronics and high-density data storage. However, electromagnetic waves also carry spin and orbital angular momenta. In a recent paper, the...
LiFi research to revolutionise data downloads
A new form of high speed wireless internet, which uses the lights in homes and offices to transmit data, could revolutionise the way we download and upload information in the future. Researchers from Northumbria University, Newcastle and University College London...
Efficient Near-infrared Electroluminescence from a “Metal-Free” Fluorophore
Burgeoning interest for near-infrared (NIR) organic light-emitting diodes (OLEDs) is fuelled by the huge prospects for integration in a broad range of applications, spanning from “biomedics” (for sensing, bio-imaging, photodynamic therapy, optogenetics, to name just a...
