−i−Highlights of the Papers in Synthesiology Volume 9 Issue 3 (Japanese version Oct. 2016)Synthesiology is a journal that describes the objectives and social value of research activities that attempt to utilize the results in society, the specic scenarios and research procedures, and the process of synthesis and integration of elemental technologies. To allow the readers to see the value of the papers in a glance, the highlights of the papers characteristic to Synthesiology are extracted and presented by the Editorial Board.Synthesiology Editorial BoardDevelopment of human-friendly polymeric actuators based on nano-carbon electrodes— Toward the practical realization of articial muscles — Kinji AsakaAsaka (AIST) realized soft actuators that employ ion conductive polymers as base materials using carbon nanotubes as electrode materials. The elemental technologies and research scenario are introduced by looking at ways to utilize the properties of large deformation at low-voltage and in thin lm form with excellent processability. The prototype was made and evaluation tests of the thin and light lm braille displays were conducted by joint research with a company, and it is an excellent example by which the social value of the product has been increased.High quality large-area graphene synthesis with high growth rate using plasma-enhanced CVD— Toward a high throughput process — Masataka Hasegawa et al.Hasegawa (AIST) et al. aimed for the use of transparent conductive lms and demonstrated the superiority of a synthesis method using a plasma-enhanced chemical vapor deposition (CVD) process as a graphene manufacturing technology for large area, high quality, and high throughput. Through the discussions including the differences with a thermal CVD process and the comparison to competing technologies, we are able to understand the R&D scenario that led to successful development of large-area graphene transparent conductive lms. Particularly impressive is the detailed data analyses that are the basis of the solutions of each elemental technology.Radioactive cesium decontamination technology for ash— Utilization and application of nanoparticles as an adsorbent — Tohru Kawamoto et al.In response to urgent governmental demands to decontaminate the radioactive material that leaked from the TEPCO Fukushima Daiichi Nuclear Power Plant, Kawamoto (AIST) et al. developed in an extremely short time the decontamination technology for ash contaminated by radioactive cesium using Prussian blue nanoparticle materials. This synthesiological paper draws our attention because it is a summary of the technologies and overall scenario that enabled achievement of results in an extremely abnormal environment and condition, including the overview of the whole problem to original research strategies, the exchange with researchers of different fields, and the collaboration with stakeholders of companies, the government, local governments, and local residents.Development of HASClay® as a high-performance adsorption material— Developing adsorbents for energy conservation systems from a kind of clay nanoparticle — Masaya Suzuki et al.Suzuki (AIST) et al. developed synthetic clay mineral HASClay® under a clearly set scenario aiming for application as desiccant air conditioning adsorbents, starting from the basic research on the structures and functions of allophene and imogolite that are natural clay minerals. It is interesting to see the course by which they felt the limitation of natural materials from the perspectives of low cost, synthesis cost, mass production, and adsorption functions, and embarked on creating a synthesized product that met all conditions through joint research with companies, while oscillating between basics and application.A super-growth method for single-walled carbon nanotube synthesis— Development of a mass production technique for industrial application — Kenji HataHata (AIST) developed and realized the industrial mass production technology that was composed of totally different elemental technologies from the lab-scale innovative synthesis method for single-walled carbon nanotubes that he originally developed. This is truly world-leading nanotechnology where the passion of the author and the company contributed to its realization. This paper is worth reading as the diverse elemental technologies that were determined essential, their advancement, and the scenario for integration through corporate collaboration are presented concisely, under a research policy conceived by the author.Electronic journalURL J-Stagehttp://www.aist.go.jp/aist_e/research_results/publications/synthesiology_e/ https://www.jstage.jst.go.jp/browse/syntheng
