Surface scientific approach for developments in fuel cell's catalysts

 
 
 
NEXT
PREV
特徴・独自性
  • From catalytic perspective, molecular-level understanding of surface phenomena occurring at nano-sized metal (alloy) particle surfaces is a key for developing highly active and durable catalysts. Our experimental approach for studying catalysis is preparations of well-defined metals or alloy surfaces by using ultra-high vacuum (UHV) and molecular-beam-epitaxy (MBE) techniques. We routinely use UHV-MBE, surface vibrational spectroscopy (IR, Raman), scanning probe microscopy (SPM), electron spectroscopy (XPS), electrochemical (EC) voltammetry, gas-chromatography (GC) etc., and try to clarify the solid surface phenomena on atomic, molecular-levels. We believe our research results directly link to future eco-friendly society.

Study on Land Use Management and Residential Movement in Tsunami Affected Areas

 
 
NEXT
PREV
特徴・独自性
  • 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.
実用化イメージ

I have practical experience in post-disaster land use and workshops with local residents. I believe that they will be able to make use of their knowledge and experience in the pre-disaster reconstruction efforts in the areas that are expected to be affected by the disaster in the future.

Development of Immunobiotic Evaluation System for Functional Feeds as a Livestock Animal Model

 
 
NEXT
PREV
特徴・独自性
  • Pattern recognition receptor (PRR) family plays an important role in the defense through recognition of pathogen-associated molecular patterns or microorganisms-associated molecular patterns (PAMPs/MAMPs).
  • Some functional feed materials are thought to regulate intestinal immunity by contact and stimulation of epithelial cells and immunocompetent cells via PRRs in the gastrointestinal tract and induction of cytokine production. In this "new world" of feed immunology, however, much remains unknown about the underlying mechanisms of intestinal immunity because of lack of appropriate intestinal immunoassay system for livestock animals.
  • We have advanced application of originally established porcine and bovine intestinal epitheliocytes (PIE, BIE) cell lines (see photo) for evaluation of immunobiotics and immunogenics exerting anti-inflammatory responses both in PIE cell monolayer and co-culture system with porcine peyer's patch immune cells as a peyer's patch culture model (see illustration).
実用化イメージ

This evaluation system may also contribute to elucidate immunoregulatory mechanism of immunobiotics and immunogenics mediated by pattern recognition receptors essential to future development of not only immunobiotic feeds but also vaccines using immunobiotics to prevent specific diseases. This can benefit mankind by offering immunobiotic feeds as a safer alternative to conventional antibiotic drug therapy.

High-speed X-ray phase tomography with a millisecond-order temporal resolution

 
NEXT
PREV
特徴・独自性
  • We successfully realized millisecond-order X-ray phase tomography using a fringe-scanning method in grating-based X-ray interferometry. We obtained phase tomograms with a measurement time of 4.43 ms using a white synchrotron X-ray beam. The use of a fringe-scanning method enables us to achieve not only a higher spatial resolution but also a higher signal-to-noise ratio than that attained by the Fourier transform method. In addition, our approach can be applied to realize four-dimensional or high-throughput X-ray tomography for samples that can be rotated at a high speed.

Advanced Molecular Transformations by Organocatalysts

 
 
NEXT
PREV
特徴・独自性
  • The development of organic molecules which function as a catalyst has been extensively investigated to achieve selective and efficient transformation of organic molecules. Brønsted acids and bases are commonly employed as the catalyst in synthetic organic chemistry. To aim at their functionalization, axially chiral phosphoric acids and axially chiral guanidine bases have been developed as chiral Brønsted acid and base catalysts, respectively. A variety of optically active compounds has been synthesized through the development of highly stereoselective reactions using these catalysts.
実用化イメージ

The development of chiral Brønsted acid and base catalysts has been accomplished as recoverable and reusable organocatalysts and highly stereoselective molecular transformations have been established using these catalysts. The present methodology is applicable to process chemistry in preparing medicines and relevant compounds on the basis of the selective and efficient molecular transformations thus developed with reduction of the waste material.

Development of New Reactions Using Organocatalyst

 
 
 
NEXT
PREV
特徴・独自性
  • Organocatalyst is a synthetically useful catalyst in synthetic organic chemistry, because of the several merits. We have been investigating the development of new and efficient organocatalysts derived from proline. We have already reported the diphenylprolinol silyl ether, which is called as a Jorgensen-Hayashi catalyst, and siloxyproline, which is effective in the presence of water. We have also developed several practical asymmetric catalytic reactions based on the organocatalysts. We also applied these reactions to the total synthesis of natural products and drugs. We have already synthesized Tamiflu in one-pot reaction, and prostaglandin E1 methyl ester via three one-pot procedure.
実用化イメージ

Our newly developed reactions using organocatalysis can be widely used for synthesis of medicines, agrichemicals, and chemical products.

Theory and practice of energy design to drive decarbonization

概要

An indispensable function for decarbonized driving is energy data analysis, an energy car navigation system with both high spatial and temporal resolution. Higher spatial resolution facilitates the recharging and discharging of electric cars and inter-regional energy exchange. With the addition of up-to-the-minute energy data with high temporal resolution, it is possible to rationally and optimally combine the fluctuating output of renewable energy with the consumers. Data analysis, system design, and operation will lead to a carbon-neutral society.

従来技術との比較

Japan's first regional energy supply and demand database has been developed, allowing for detailed design of sustainable and resilient regional energy infrastructure layout and operation based on analysis of the current energy status of cities, towns, and villages nationwide.

  • Research experience as a Fulbright Scholar in the U.S. and familiarity with examples of social implementation in Europe.
  • Data-driven innovation research approach based on a vast regional energy supply and demand database.
  • Emphasis on regional fieldwork as a social entrepreneur solving social issues.
