A technique known as solution-shearing has been utilized to generate a thin film of perovskite CH3NH3PbI3 over a large area in a facile and cost-effective manner...read more
Spatiotemporal control of gene expression or labeling is a valuable strategy for identifying functions of genes within complex neural circuits. Here, we develop a highly light-sensitive and efficient photoactivatable Flp recombinase (PA-Flp) that is suitable for genetic manipulation in vivo. The highly light-sensitive property of PA-Flp is ideal for activation in deep mouse brain regions by illumination with a noninvasive light-emitting diode. In addition, PA-Flp can be extended to the Cre-lox system through a viral vector as an Flp-dependent Cre expression platform, thereby activating both Flp and Cre....read more
Along with 5G mobile communication commercialization, B5G (Beyond 5G) and 6G mobile communication technologies are under study. As part of B5G technology, we are developing a full digital beamforming system to maximize the spatial gain through beamforming in the millimeter band. The spatial multi-mode technology in the sub-THz band is being developed for 6G mobile communication....read more
An algorithm for detecting and tracking multiple targets in marine environments was developed by a team of student researchers at KI-R. The algorithm was applied to an 8-m long unmanned surface vehicle and its performance was demonstrated in field tests in a real-sea environment....read more

Efficient solid-state photoluminescent graphene quantum dots embedded in boron oxynitride (GQD@BNO) was applied to AC powder electroluminescent device for the first time. ...read more
Professor Seokwoo Jeon’s research team has developed a solution-phase synthesis method of two-dimensional WO3 nanosheets chemically converted from layered WS2 for the first time, to fabricate high-performance and robust electrochromic devices....read more
Functional hyperemia in the rat cortex was investigated using high-speed optical coherence tomography (OCT) angiography. OCT angiography (OCTA) was performed to image the hemodynamic stimulus-response over a wide field of view. Temporal changes in vessel diameters in different vessel compartments were measured in order to monitor localized hemodynamic changes. This research demonstrates the potential of OCTA for the investigation of neurovascular coupling in small animal models....read more
