Selenium insolubilization 01/13/2021

Microorganisms That Survived in Rock Stop Heavy Metalloid Contamination from Rock Mass
– A step forward in development of selenium insolubilization technology that prevents environmental outflow of the pollutant selenium –

In collaboration with Taiheiyo Cement Corporation, AIST discovered that living microorganisms are present in rock mass produced by tunnel construction work etc., and that those microorganisms insolubilize selenium, which is a harmful and difficult-to-treat heavy metalloid naturally contained in rock mass.

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.

Flow synthesis 01/19/2021

Development of Continuous Synthesis Method for Fine Chemical Intermediates
– Establishment of environment-friendly manufacturing technology using flow organic synthesis –

AIST has developed a continuous flow synthesis technology for preparing aryl amines, which are important synthetic intermediates for fine chemicals, with small amounts of easily removable co-products. The developed flow system consists of two column reactors containing heterogeneous catalysts.

Transistor architecture 12/08/2020

Development of New Transistor Architecture for the 2nm Node
– Aggressive integration through Si/Ge stacked channel heterogeneous complementary field effect transistor (hCFET) –

AIST and the Taiwan Semiconductor Research Institute fabricated a Si nFET /Ge pFET vertically stacked heterogeneous complementary field effect transistor for the 2nm node. This ultimate new device architecture can lead to the realization of higher performance and lower power consumption CMOS devices.

Volcano map 11/24/2020

Development of a Web-Based Integrated System to Display Information on 440 Quaternary Volcanoes Across Japan at a Glance
– Published the “Geologic Map of Volcanoes in Japan (1:200,000)” database with the world’s highest level of accuracy –

AIST has published the Geologic Map of Volcanoes in Japan that lets you view and search for a distribution of volcanic eruption products and geological information of about 440 quaternary volcanoes across Japan as a new addition to the “Volcanoes of Japan” databases.

Particle classification 01/14/2021

High Resolution of Size Classification of Particles from 10 nm to 40 µm Was Achieved
– Establishment of the centrifugal field-flow fractionation system with centrifugal acceleration over 15000 G for the first time in the world –

AIST constructed an original rotor rotation mechanism that enables both sealing and high-speed rotation. The mechanism was introduced in a novel centrifugal field-flow fractionation system. The system can classify particles of a wide size range from 10 nm to 40 µm.
