- Tocotrienol, one of vitamin E, has recovered by the conventional method with molecular distillation from deodrizer distillate discharged from the oil refining processes. However, tocotrienol easily loses its activity due to its low thermal stability, so that its recovery ratio and purity were extremely low. We proposed a novel method to selectively recover tocotrienol by adsorption/desorption using anion-exchange resin at 50 degree C. Tocotrienol is retained on the resin by ion-exchange reaction, and then released and recoverd from the resin by other ion-exchange reaction. Prior to the adsorption/desorption, free fatty acid, a major component of the feed, should be removed by esterification using cation-exchange resin at 50 degree C.

This innovative technology succeeds in solving the serious problems in the current tocotrienol production, the large weight loss due to the thermal decomposition and large amount of remaining impurities. This technology applies to the production of not only tocotrienol but also tocopherol as bioactive compounds s in food chemicals.

- In Japan, the percentage of elderly people aged 65 years or over was 23.1% in 2010. It is no doubt that Japan is the world's first super-aging society. In such a super-aging environment, it is necessary to form a society in which each individual can play an active role even as one becomes older in order to maintain and improve the quality of life of all people and to maintain a healthy society. In advanced brain science, research from the fields of brain function imaging, cognitive science, and psychology has been utilized with the aim of realizing a healthy aging society. Up to date information on various new technologies and related discoveries has been disseminated so that individuals can live a healthy life with peace of mind at every stage of aging, while maintaining and improving the health of their brain and mind in a diverse and complex society.

We believe to overcome super-aging environments is not only an object of public concern but also big business chances to create new industries.

- The study focused on areas affected by the tsunami caused by the Great East Japan Earthquake, and clarified the impact of reconstruction projects on spatial transformation and residents' residential relocation, as well as residents' satisfaction with the projects. In the boundary area of architecture, urban planning, and landscape architecture, we combine qualitative research, such as participatory observation with sociological and local community perspectives, and quantitative research using data obtained in the field. I would like to explore better relationships between people and nature, and propose methods that lead to sustainable urban development.

- Plants have immune system against pathogen infection. In our research group, isolation of disease resistance genes, analysis of signal transduction pathways for disease resistance and characterization of defense-related proteins have been performed so far. In addition, we produced transgenic plants expressing green fluorescent protein under the control of defense-inducible promoter, which will be useful to visualize the induction of defense system.

- Phase change random access memory (PCRAM) has attracted attention as next-generation non-volatile memories. A conventional PCM is Ge-Sb-Te which shows a fast crystallization speed and an excellent reversibility of phase transition. However, Ge-Sb-Te has a low crystallization temperature of about 150 ºC and a high melting temperature of over 600 ºC , which limits data retention and causes high power consumption, respectively.
- We have developed a new phase change materials with high crystallization temperature and low melting point such as Ge-Cu-Te etc, which have high potential as PCRAM materials with high thermal stability and low power consumption (Fig.1,2).

- Tactile sense and the sense of touch are multiple combinations of fundamental sensations, such as smooth and rough, soft and hard, dry and wet, and hot and cold sensations. These sensations are described with the information on force, distortion, temperature, stickiness and oscillation.
- A tactile sensor corresponding to several types of human skin sensory receptors and an active tactile sensor system that is an integrated sensor structure imitating human haptic motions have been developed. These sensor systems allowed measurement of "Kansei" words that are extremely vague tactile feelings, and roughness, softness and temperature sensations. However, tactile sense or the sense of touch also includes other sensations and combinations of them. Therefore, to develop a sensor, it is important to define how the sensations and physical information relating to the sensations are obtained and what relationships exist between them.
- In this research, the relationships between sensations, including fundamental sensations that have already been obtained and other sensations, and the relevant physical information are being investigated. Additionally, on the basis of the knowledge through the investigation, an advanced sensor system that allows obtaining haptic information is being developed.
