Antifreeze proteins adsorb to ice crystals and have the function of suppressing their growth. To apply antifreeze proteins to frozen foods where the coarsening of ice crystals leads to the deterioration of quality, we advance mass production technology. However, there were not many cases where the quality of frozen foods was improved by adding the antifreeze protein we developed. So, we changed the direction of development and conducted market research. Our market research revealed new possibilities for utilizing antifreeze proteins. We promoted the development of products that meet the needs of users and began sales as research reagents in 2016. Currently, we are working to address user problems, while manufacturing and selling research reagents.

When the project is organized into Fig. 1, one realizes that when research results progress to the next stage, collaboration with human resources with different specialties is important, and it can be seen that the key point is to transmit the significance of the research results in a comprehensive manner when building such collaborative relationships and to have the results be recognized widely throughout society in the process of “result dissemination.” Since the field of specialties were totally different among the specialists who had the knowledge of plant operation for waste disposal plants at Mitsui E&S, the researchers working on chemical reaction and molecular design at the Interdisciplinary Research Center for Catalytic Chemistry, AIST, and the researchers studying chemical engineering or surface chemistry at the Research Institute for Chemical Process Technology, AIST, there was no opportunity for these people to directly exchange opinions in usual activities such as at academic meetings or at paper presentations. As R&D specialties become more diversified, it is becoming difficult to scan other fields or even science and technology in general. Therefore, events such as the Techno Bridge Fair in which AIST’s technological potential is introduced to people of industry are important, so they can get an overview of the research conducted at AIST and to transmit the results widely and systemically.

Feasible countermeasures are needed to address soil and groundwater contamination problems, because of its impact on human health and socioeconomic activities. Soil and groundwater contamination is a complex issue that requires an interdisciplinary effort involving research into contaminants, their practical removal, and social implementation. This paper discusses several areas of research that the author has been involved in this regard.

Development of equipment onboard ASTRO-H was conducted under wide-ranging international cooperation. Therefore, development that ensured continuation of the conventional development as well as compliance to international standard was required. The SpaceWire international standard employed for ASTRO-H was a de jure standard that the European Space Agency (ESA) oversaw. We were able to incorporate proprietary standards that were formed with Japanese scientific satellites over the years into the international standard.

According to the NEDO roadmap for FY 2013 in Japan, an all-solid-state battery is positioned as a product that fully covers the potential of a next-generation battery, and is set for practical utilization in 2030. The conventional lithium secondary battery is roughly composed of four parts: a positive electrode, a negative electrode, an electrolyte, and a separator that separates the positive and negative electrodes. On the other hand, an all-solidstate lithium secondary battery is composed of three parts: a positive electrode, a negative electrode, and a lithium solid electrolyte (a lithium ion conductor), and the lithium solid electrolyte plays the roles of both an electrolyte and a separator.

Because of their unique and excellent material properties, ceramics are often used as key parts in many advanced products and systems in a variety of f ields including manufacturing, energy, environments, IT, electronics, optics, bio-technologies, and transportation. It is also noteworthy that Japanese ceramic industries have maintained the world’s highest-level manufacturing technologies, which have brought about almost a half of the global market share of ceramic-related products, thanks to their incessant efforts for technological innovation.
