Materials and Chemistry

Contributing to industrial competitiveness enhancement by synergistic interaction between materials and chemical technologies

We are developing technologies to enhance added value of functional chemicals, and to realize practical use of new materials, with strengthening value chains of materials through synergistic interaction between materials and chemical technologies in mind. Thus, we are aiming to contribute to the primary materials and chemical industries.

A Facile Method for Preparing Transparent Anti-Fogging Films with Quick Self-Healing Abilities

Researchers in AIST developed a facile fabrication method for transparent nanocomposite films with long-lasting anti-fogging and excellent self-healing properties. This method is based on significant improvements in both the composition and fabrication process of nanocomposite materials originally developed by AIST. Thanks to the development of this method, the self-healing time for severe physical damages can be reduced from 24-48 hours to 3 hours.
The nanocomposite films can suppress fogging on transparent substrates such as lenses and glass for a long period. They are also expected to be effective in improving user visibility and safety and prevent efficiency loss in medical and analytical devices, sensors, and solar panels, etc.

Successful Identification and Visualization of Isotopes at the Atomic Level

Researchers in AIST developed a technique to detect and trace isotopes on the order of a few atoms by using transmission electron microscopy in collaboration with Osaka University, the Japan Science and Technology Agency, and JEOL Ltd.
The developed technique of electron spectroscopy using a monochromatic electron source enables the isotope detection with a spatial resolution of less than one nanometer by measuring the difference in the vibrational energy of atoms which reflects a weight difference equivalent to a single neutron. The spatial resolution achieved in this study is more than one or two orders of magnitude higher than existing isotope detection techniques. In addition to conventional structural analysis and chemical assignment, this development allows a transmission electron microscope to distinguish isotopes that has never been possible. In the future, it may also be possible to track isotopes at the monoatomic and monomolecular levels. This will reveal where and how chemical and biological reactions occur, contributing to a wide range of fields such as basic research in materials science and biology, and drug discovery research.

Research Laboratory

Open Innovation Laboratory

Since FY 2016, as a part of the “Open Innovation Arena concept” promoted by the Ministry of Economy, Trade and Industry (METI), AIST has created the concept of “open innovation laboratories” (OILs), collaborative research bases located on university campuses, and has been engaged in their provision. We are planning to establish more than ten OILs by FY 2020.

AIST will merge the basic research carried out at universities, etc. with AISTʼs goal-oriented basic research and applied technology development, and will promote bridging research and evelopment and industry by the establishment of OILs.

Cooperative Research Laboratories

In order to conduct research and development more closely related to strategies of companies, we have established collaborative research laboratories, bearing partner company names.

Partner companies provide their researchers and funding, and AIST provides research resources, such as its researchers, research facilities, and intellectual property. The loaned researchers of companies and AIST researchers jointly conduct research and development.

By setting up cooperative research laboratories, we will accelerate the commercialization of our goal-oriented basic research and application research with partner companies.
