By putting theory into practice, Prof. Pi-Tai Chou’s research team has repeatedly broken the world record for NIR organic luminophores, overcoming the energy gap law. In 2017, we developed a material with an external quantum efficiency (EQE) of 24% at 740nm, followed by a molecule with an EQE of 10% at 800nm in 2018. In 2020 and 2022, through deuterium substitution, we successfully developed unprecedented OLEDs with an EQE of 4% at 1000nm. However, developing new cutting-edge materials is challenging. Alternatively, in terms of device engineering, we have been continuously exploring new techniques to further enhance efficiency using existing materials. This paper, published in Nature Communications (2024, 15 (1), 4664), marks the first time internationally that transfer technology has been successfully utilized to break the energy gap law through energy transfer, achieving record-breaking efficiency.

The traditional optimal audio experience depended on the interplay between space, speakers and music carriers, such as CDs or vinyl records. Invisible Tech, a local start-up specialising in acoustic design, uses recycled wine crates, wood waste and reclaimed furniture to produce a range of speakers. With the support of HK Tech 300 of City University of Hong Kong (CityUHK), Invisible Tech worked with CityUHK audio technology researchers to develop a sound system tailored for the modern living environment and habits. The system is designed to provide users with immersive surround sound music enjoyment.

Walking and running is notoriously difficult to recreate in robots. Now, a group of researchers has overcome some of these challenges by creating an innovative method that employs central pattern generators - neural circuits located in the spinal cord that generate rhythmic patterns of muscle activity - with deep reinforcement learning. The method not only imitates walking and running motions but also generates movements for frequencies where motion data is absent, enables smooth transition movements from walking to running, and allows for adapting to environments with unstable surfaces.
