Magnetic vortices: Controlling core switching in Pac-man disks

Magnetic vortices in thin films can encode information in the perpendicular magnetization pointing up or down relative to the vortex core. These binary states could be useful for non-volatile data storage devices such as RAM memories, but the switching between them must be fast and energy-efficient. However, despite many efforts switching is still...

Innovative nanophotonics: Integrating quantum light sources with nanofibers for quantum internet applications

"I had the idea for 'nanofiber quantum photonics' about 14 years ago," says Kohzo Hakuta, Director of the Center for Photonic Innovations at the University of Electro-Communications (UEC). "I want to integrate quantum light sources e.g. single quantum dot / single atom, into specially designed nanofibers. This 'fiber in-line technology' holds the potential...

Getting into your head: Gelatin nanoparticles could deliver drugs to the brain

Stroke victims could have more time to seek treatment that could reduce harmful effects on the brain, thanks to tiny blobs of gelatin that could deliver the medication to the brain noninvasively. University of Illinois researchers and colleagues in South Korea, led by U. of I. electrical and computer engineering senior research scientist Hyungsoo Choi...
