- Our lab develops accurate nanometer scale characterization methods of crystal structures by convergent-beam electron diffraction (<strong>CBED</strong>) and electronic structures by electron energy-loss spectroscopy (EELS) and soft-X-ray emission spectroscopy (<strong>SXES</strong>) for evaluating new functional materials. For performing crystal structure studies, we developed a new Ω-filter electron microscope and a refinement soft-ware, which can perform not only atom positions but also electrostatic potential and charge distributions. For electronic structure studies, a high-resolution EELS microscope and SXES instruments were developed.

- In contrast to other scattering techniques, such as x-ray and electron diffractions, neutron scattering has the following advantages: 1) light atoms, such as H and Li, can be detected; 2) electron spins can be detected; 3) low energy excitations can be investigated. Using the neutron scattering technique, we search for macroscopic quantum phenomena in many-body electron systems, such as macroscopic singlet ground states in the quantum frustrated magnets and spin-fluctuation-mediated unconventional superconductors.
- 実用化イメージ
-
As noted above, neutron scattering can be used for investigating magnetic structure, spin dynamics, light atom positions in crystalline materials and their dynamics. Hence, this technique is very useful when those pieces of information are to be known.

- Complexity of the cardiac contraction sequence is still not fully understood because the dynamic mechanical excitation process, which directly correlates with contraction, cannot be accurately measured by CT, MRI, SPECT, or conventional ultrasound. By developing a noninvasive novel imaging modality with high temporal and spatial resolutions (US patent 5840028), we have detected the minute mechanical response (velocity component) to the propagation of the action potential in the human heart or to detect the propagation of the vibrations along the heart wall caused by the valve closure (Fig. 2).
- By applying the same procedure to the human arteries, the regional change in wall thickness caused during one cardiac cycle can be measured with high spatial resolution (Fig. 1). From the measurement, the regional elasticity of tissue surrounding atherosclerotic plaque can be determined. By comparing the pathological findings with the distribution of elasticity, elasticity of lipid and that of fibrous tissue were determined. Thus, each point inside the plaque is classified into lipid or fibrous tissue using transcutaneous ultrasound (Fig. 3).

This novel method offers potential as a diagnostic technique for detection of plaque vulnerability with high spatial resolution.
We are prepared to provide academic consultations to companies interested in our research.

- 概要
Floating wind turbine and next-generation aircraft have high-aspect-ratio blade and wing that undergo nonlinear aeroelastic deformation. We have developed a nonlinear aeroelastic analysis framework with absolute nodal coordinate formulation (ANCF). This nonlinear aeroelastic deformation is coupled with multibody dynamics. We are also developing a novel analysis framework for this coupling dynamics.

By using the nonlinear analysis method proposed in this study, it is possible to handle the reduction in flutter speed due to large deformations and the coupled phenomenon of deformation and flight behavior that cannot be captured using conventional linear analysis methods.

- Nonprofit organizations strive to solve community and social problems and to create new social values. Nonprofit organizations have the role to create citizenship and social capital - trust, norms and networks - in community. Social capital, an invisible and soft capital has increasingly become important to a sustainable management of an organization.
- We hope to conduct collaborative research with willing corporations and organizations for measuring social capital at community/organizational levels and for making practical proposals on how to create and utilize social capital with viewpoints of partnership with nonprofit organizations and human resource development.

- General metallic biomaterials, such as stainless steels and conventional CoCr alloys, show a high Young's modulus ten times higher than that of human bones. This is an unfavored feature because it causes the so-called "stress shielding effect" when they are used as implants. β-type Ti alloys have a relatively lower Young's modulus, but they come with a compromise of low wear resistance. The current novel CoCr-based alloys are a breakthrough; they exhibit both a low Young's modulus similar to human bones and a high wear and corrosion resistance. Moreover, they exhibit superelasticity with a huge recoverable strain over 17%, also showing promise as shape memory alloys.
- 実用化イメージ
-
It is the first time that a low Young's modulus, a high corrosion and wear resistance, and a superior superelastic behavior are simultaneously obtained in a single material. The current novel CoCr-based alloys are promising for biomedical applications such as total hip or knee joint replacements, bone plates, spinal fixation devices, and vascular stents.

- In recent year, facing the age of nanoscale engineering, the new technologies of device, circuit and architecture supported by novel physical guidance principles are highly expected, just as the similar situation as the predawn of semiconductor technology when Bardeen and Shockley discovered the secret of transistors. Therefore, in our research approach, the architectures, circuits, devices and CAD design tools for nanoscale LSI are systematically investigated in the following three main research subjects.
- 1. Study on nanoscale device and circuit
- Aiming at the nanoscale silicon semiconductor integrated circuit, we are mainly working on the following directions for new devices and circuits:
- ①Analysis for novel physical phenomenon based on nanostructural effects
- ②Device and circuit technology with new operating principle
- ③Restraint technology for increasing variability of device characteristics
- ④Architecture and circuit technology for robust information processing
- 2. Study on the 3-dimention-structual device and circuit
- The elementary element of recent LSI with planar-structural devices is coming close to the physical limitation of scaling. In order to break the limit and sustain the evolution of future LSI performance, we have started the research on the novel 3-dimension-structural devices and circuits.
- 3. research on wireless integrated circuit (IC) based on information transmission
- The ultracompact lightweight wireless IC is one of essential technologies for realizing the ubiquitous society which has the network available in anywhere, at anytime and from any surrounding items. For example, the IC tags for receiving information with reading function are getting close to the practical applications. In our laboratory, aiming at the automatic operating wireless IC with embedded power supply, we are systematically working on the following directions:
- ①The electrical power generation and storage devices
- ②Devices and circuits with Ultralow power consumption
- ③Sensing devices
- For all above subjects, We hope to conduct collaborative researches with companies interested in our research.
