Phys.org / Supramolecular nanofibers paired with nanohole substrate improve exciton transport in organic solid

Self-assembling, anthracene-based supramolecular nanofibers can enable excitons to migrate hundreds of nanometers, according to a new experimental finding by researchers at Science Tokyo. Coupling these nanofibers with a ...

Phys.org / 3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times

At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world. Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous ...

Phys.org / AI prompts offer a new tool for mapping how emotion concepts relate

How similar are "joy" and "surprise"? Conversely, how far apart are "joy" and "sadness"? We naturally organize words that express emotions—such as "happy," "afraid," and "angry"—according to similarities and differences in ...
