Graphite has been widely used as an anode material for lithium ion-batteries. However, its low storage capacity falls short of meeting current demands for high-capacity batteries required for long-range electrical vehicles and renewable energy storage. In a new study, researchers developed a novel germanium (Ge)/LiAlGePO composite material for LIB anodes that significantly improves storage capacities and capacity retention. This new anode material can lead to next-generation LIBs that can support the growing renewable energy demand.
A multi-institutional research team led by Osaka University has introduced a piezoelectric device that can measure acceleration and pressure simultaneously. The device can be manufactured at room temperature and is made from inexpensive materials, which makes it a promising candidate for a wide range of applications, including the maintenance of industrial machinery and disaster mitigation.
Led by Assistant Prof. Kou Li, a research group in Chuo University (President: KAWAI Hisashi, Hachioji-shi, Tokyo, Japan), under a collaboration with National Institute of Informatics (Director-General: KUROHASHI Sadao, Chiyoda-ku, Tokyo, Japan), has developed a synergetic strategy among millimeter-wave–terahertz–infrared photo-monitoring and computer vision three-dimensional modelling toward ubiquitous non-destructive inspections, with a recent paper publication in Advanced Materials Technologies.
Tokyo, Japan – Researchers from Tokyo Metropolitan University have developed a way to treat ageing-related muscular atrophy using regenerative medicine. Conventional methods to implant myoblasts, precursors to muscle fiber, required prior scarring for the new cells to graft properly. By adding extracellular matrix (ECM) fluid into the implant, the team successfully grafted myoblasts onto healthy muscle in mice. Their technique opens the way for using implantation to treat unscarred muscle atrophied by ageing.
Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently, as reported by the researchers from Science Tokyo, Japan. This effectively aligns with the growing demand for speed and efficiency, accelerating the widespread deployment of wireless devices. This enables synergistic operation of wireless electronic devices and better quality of modern life.Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently, as reported by the researchers from Science Tokyo, Japan.

Kyoto, Japan -- Asteroids that orbit close to the Earth inevitably cause us some anxiety due to the even remote possibility of a collision. But their proximity also offers ample opportunities to learn more about the universe. Ryugu, a 900-meter diameter asteroid in the Apollo belt, has recently proven useful in our search for signs of life's precursors elsewhere in our Solar System.
A team of researchers at Kyoto University have found evidence of salt minerals in samples recovered from Ryugu during the initial phase of Japan's Hayabusa2 mission. The discovery of these deposits, containing sodium carbonate, halite, and sodium sulfates, suggest that liquid saline water once existed within a parent body of Ryugu.
Before examining the samples, the team expected that sample grains returned from the asteroid might contain substances not generally found in meteorites. They anticipated that these could be highly water-soluble materials, which readily react with moisture in Earth's atmosphere and are difficult to detect unless examined in their pristine state as preserved in the vacuum of space.
Porous organic crystals with superior properties as CO2 adsorbents were created by researchers at Institute of Science Tokyo. Owing to the novel 2.5-dimensional skeleton, the materials feature ultrahigh-density amines. The covalently-bonded microporous skeleton and high crystallinity realize fast CO2 adsorption and high thermal stability. Their low adsorption heat, only one-fourth of the current amine scrubbing method, and their light-elemental nature can reduce the cost for CO2 separation from flue gases.
