Machine learning for personalized education   A new machine learning algorithm was created for building next-generation education systems with personalized curriculums. Using a large-scale education datasets collected from a mobile app, a novel machine learning algorithm is proposed to provide individual students with personalized curriculums by estimating their learning progress.   Article &n...

HUMICOTTA: A 3D-printed ceramic humidifier that is bacteria-free, easy-to-clean, and energy-efficient   HUMICOTTA is a 3D-printed ceramic humidifier. It is bacteria-free, easy-to-clean, and energy-efficient. It consists of a base module and a filter part. The base is a cylindrical pedestal with a built-in fan on which the filter can be placed. The filter is a 3D-printed honeycomb structure made of diatomite....

Novel Si photoelectrodes architecture with nanostructured Au catalysts to reduce CO2 into CO   A novel strategy has been proposed for converting carbon dioxide (CO2) into carbon monoxide (CO) by using solar energy and water. Nanostructured Au, with a superior catalytic property for reducing CO2 into CO, is placed on a Si photoelectrode as a co-catalyst. Solar-generated carriers in a Si photoelectrod...

SCAN: Social context-aware smartphone notification system   SCAN (Social Context-Aware smartphone Notification system) introduces a novel way to reduce interruptions caused by smartphone notifications during a social interaction. It uses built-in smartphone sensors to detect the social context of a user and delivers notifications only when they do not interrupt an ongoing social interaction.   Article&n...

Highly stretchable, durable, and manufacturable tactile sensor for robotic skin   A novel soft tactile sensor, which is highly stretchable, durable, and manufacturable, is developed to make robotic skin a reality in the future. Since this sensor used a highly conformable force-sensing nanocomposite as a sensing material, the mechanical property of this material is similar to that of human skin. Furthermore, t...

Bio-based p-xylene oxidation into terephthalic acid by engineered Escherichia coli   A novel and efficient biocatalysis system was created to produce terephthalic acid (TPA) from p-xylene (pX) through two-phase microbial fermentation of an engineered gut bacterium (Escherichia coli). It will make this globally-important bulk chemical available in an environmentally-friendly manner.   Article&n...
