CO2 Utilization 11/19/2021

Development of a High-Concentration Methane Production Process from Atmospheric CO2
– Direct synthesis of methane without pretreatment of CO2 capture and separation process –

Researchers in AIST developed a process for producing high-concentration methane from low-concentration CO2 in collaboration with the Delft University of Technology. The concentration of CO2 as a feed covers the concentration range from dilute atmospheric CO2 to CO2 originating from power plants. This process does not require a CO2 capture and separation process prior to the conversion process.

Symbiotic bacteria 01/06/2021

Symbiotic Bacteria Play Different Roles in Host Insect Larvae and Adults
– Elucidation of the relationship between insect metamorphosis, lifestyle change, and microbial symbiont –

AIST determined the genome and analyzed the biological functions of the symbiotic bacterium found in leaf beetles. This study revealed for the first time that one species of symbiotic bacteria can perform different functions in larvae and adults of the same host insect.

3D circuits 03/11/2021

Development of Technology for Easy 3D Shaping of Electronic Circuits
– Forming component-mounted circuits into three dimensions without damage –

AIST has developed a thermo-projection shaping method that enables easy high-speed 3D shaping without damage to electronic circuits fabricated on a flat resin sheet. The heat applied to the sheet during shaping is partially blocked to create non-deforming areas, thus avoiding damage to the circuits.

Liquid crystal nanostructuring 10/04/2021

Multistep mechanism of nanostructure formation in liquid crystal
– Combination of molecular simulation and AI technologies towards development of highly functional materials –

In collaboration with Kyushu University, the researchers at AIST have developed a novel analysis method that combines molecular simulation and artificial intelligence to observe the process of the formation of characteristic nanostructures in quenched liquid crystals.

Low reflectivity 04/05/2021

Development of Optical Components with Both World Top-Level Wide-Angle Low Reflectivity and Anti-fogging Properties
– Contribution to increasing functionality of anti-reflective coatings for objects with complex shapes such as lenses, LCD panels and automotive instrument panels –

AIST has developed a technology that fabricates anti-reflective nanostructures with world top-level low-reflection characteristics over a wide incident angle range by injection molding. In addition, a newly developed self-forming column formation technology is used to form column-shaped structures to achieve anti-fogging effects.

Novel phylum 08/27/2021

A membrane-bounded genome in a bacterium isolated from a deep biosphere
– Isolation of a novel bacterium of an as-yet uncultivated phylum reveals a unique cell structure –

In collaboration with JEOL Ltd. and Marine Works Japan Ltd., the researchers in AIST succeeded in culturing strain RT761, a bacterium that plays an important role in methane production in deep subsurface environments such as natural gas fields.

Dosimeter 10/26/2021

IoT-compatible Radiation Dosimeter for real-time and on-site monitoring
– A system capable of monitoring large numbers of dosimeters and maintaining accuracy over long periods –

Researchers at AIST has been developed a compact radiation dosimeter using power-saving wireless technology. It does not require battery replacement for two years or more. The newly developed dosimeter combines the low power consumption technology developed by AIST at the time in response to the Fukushima Daiichi Nuclear Power Plant Accident with the latest IoT (Internet of Things) technology. This enables to check the radiation dose transition over time directly on the dosimeter unit display or an information terminal such as a smartphone, with almost no concern about battery drain.
