Researchers from The University of Osaka discovered a mechanism that greatly improves the efficiency of endothermic singlet exciton fission. By combining singlet-fission molecules with quantum dots, the team created hybridized electronic states at the material interface that act as intermediate energy pathways. This allows one absorbed photon to generate two excited states with high efficiency, potentially allowing solar technologies to exceed current efficiency limits.

- A joint research team from DGIST, UNIST, and IBS has developed a double-layer dry transfer printing technology that simultaneously transfers light-emitting and electron-transferring layers onto a substrate, enhancing AR/VR immersion. - Research results have been published in Nature Photonics.

A key innovation in photonic (light-driven) microelectromechanical components could transform computing technology, increasing efficiency while reducing power consumption and chip size.

- DGIST Professor Jin Ho Chang and Jae Youn Hwang's joint research team revealed for the first time in the world that the depth focused light can be increased by using a bubble layer temporarily created using ultrasound. - The collaborative research of ultrasound and optical imaging experts is expected to overcome the physical limitations of optical imaging and treatment depth.
