A hyperspectral imaging camera that fits in your pocket   Prof. Min H. Kim’s team at the KAIST School of Computing has developed a new hyperspectral imaging method that enables hyperspectral imaging with only a single diffractive optical element. The method does not require any additional optics for snapshot hyperspectral imaging technology. This is the core technology that will make hyperspectral imagi...

Monitoring and mitigation of ionospheric anomalies for GNSS-based safety-critical systems: towards ‘wheels on runway’ in all weather conditions at airports worldwide   Ionospheric anomaly threat models and mitigation techniques were developed via systematic and comprehensive analysis on the characteristics of ionospheric anomalies for each geomagnetic region. The developed techniques would enable ...

Atomic-scale engineering to boost oxygen evolution electrocatalysis in perovskite oxides   By utilizing epitaxial thin-film materials, it is directly demonstrated that simple exchange of Fe in the surface region is highly effective in boosting the catalytic activity for the oxygen evolution reaction. Furthermore, strong distortion of oxygen octahedra at the angstrom scale is identified to be readily induced ...

Engineering of an oleaginous bacterium for the production of fatty acids and fuels   The metabolic engineering of an oleaginous microorganism, Rhodococcus opacus, has enabled the highest fatty acid and biodiesel (fatty acid ethyl esters and long-chain hydrocarbons) production efficiency ever reported. These will serve as promising platform strains for the sustainable production of a wide range of fatty a...

Ultra-stable transfer of laser light over an 18 km open-air link: Multichannel high-density coherent optical & microwaves transmission for next-generation space communications   An advanced technique of free-space optical frequency transfer has been demonstrated with the aim of realizing next-generation optical communications in space between satellites and ground stations. Optical phase noise caused by ...

Self-exploring autonomous drone: ready to rescue survivors in underground locations that first responders cannot reach   Combined with the latest AI technologies, drones can autonomously navigate through a complex environment using only its onboard sensors such as laser scanners and cameras, searching for survivors trapped in remote underground areas. In the AI Grand Challenge, a premier AI-centered competit...
