Photons, the elementary particles that make up light, have been the subject of study by researchers at the University of Twente. Unlike electrons that occupy regions around atoms in defined orbitals, photons exhibit a much greater variety of behaviors and are easier to control. These insights into the behavior of photons have promising applications in
In the realm of organic light-emitting diodes (OLEDs), the search for materials that can produce narrow electroluminescence (EL) spectra is ongoing. One promising avenue for achieving this is through the use of Multi-resonance thermally activated delayed fluorescence (MR-TADF) materials. These materials have the potential to revolutionize OLED technology, but they are not without their challenges.
The recent research conducted at Finland’s Aalto University has revealed an innovative way to manipulate bacteria through magnets.
