[Ubiquitylation]
Elucidation of oncogenesis by Fbxw7FeaturesIn life science research field, it is noteworthy issue how information in genome is interpreted and is transferred to functional molecules. However, during these 10 years, we convinced that the amount of proteins, final functional molecules was regulated by not only by production but also by degradation. For examples, the amount of c-Myc, which promotes cell cycle and inhibits cell death, increase in many types of cancer by failure of protein degradation. Targeted Application(s)/Industry |
[ultra-low radioactivity environment]
High Sensitivity Radioactivity Measurement at Ultra-Low Radioactivity EnvironmentFeaturesResearch Center for Neutrino Science established ultra-low radioactivity environment (trillion times lower than natural environment) with 1200 cubic-meter organic scintillator detector at 1000m underground where very stable temperature/humidity and low vibration are maintained. We are pursuing high sensitivity measurements, especially neutrino observation, and are also developing purification system for ultra-low radioactivity and high performance radioactivity detectors. Targeted Application(s)/IndustryThe established ultra-low radioactivity environment is suitable for rare phenomena study and is also applicable for high sensitivity radio-impurity measurement. It may also apply to investigation of biological influence of low radioactivity irradiation. The other applications such as neutrino detection technique for monitoring nuclear reactors and medical use of high sensitivity radioactivity detectors may also be considered. |
[ultra-realistic communication]
Development of the high-quality and low-power display system for ultra-realistic communicationsFeaturesRecently, with a spread of high definition video streaming services and ubiquitous network, development of high-quality, ultra-realistic and low-power display systems has been demanded. We have been studying physical properties of liquid crystal materials, precise control technique of polarization, high performance liquid crystal display (LCD) devices and its application to the advanced display systems for the realization of new media such as electric paper display and digital signage display, and low-energy society. We established a polarization control technology which realizes a precise control of polarization with liquid crystal materials. By using this world-leading technology, we have been studying the control of the surface alignment of liquid crystal molecules and developed a wide-viewing angle and fast switching liquid crystal display, ultra-high definition field-sequential-color display (Fig. 1), ultra-low power reflective full-color display (Fig. 2) and large-size high-quality display system.

[ultrasound]
Dry-Contact Ultrasonic TechniqueFeaturesA new dry-contact technique for transduction of broadband, high-frequency ultrasound via a solid layer inserted between water and the sample, whereat the pressure of about 0.1 MPa is applied at the layer/sample interface by evacuating air between them, has been developed. Based on the technique, acoustic imaging of an electronic package is realized under the dry environment (Fig. 1). Typically, the polymer films are used as the intermediate layer for water protection of the sample, and by utilizing the acoustic resonance phenomenon among water, film and the sample, higher quality acoustic image of the testing sample than that for the water immersion case can be recorded without getting the sample wet (Fig. 2). Moreover, thin materials, e.g., polymer film (Fig. 3), etc. can be characterized by analyzing the acoustic resonance phenomenon among the three media. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry. |

Noninvasive Ultrasonic Measurement of Dynamic Properties of Heart and ArteriesFeaturesComplexity 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). Targeted Application(s)/IndustryThis novel method offers potential as a diagnostic technique for detection of plaque vulnerability with high spatial resolution.

[Ultrathin metallic wire]
Joule Heat Welding of Ultrathin Metallic Wires and its Application for Producing FunctionalityFeaturesFor producing a new functionality from metallic micro and nano matarials, the welding and cutting technologies for small scale materials utilizing Joule heat has been developed (Fig. 1). A constant direct current is supplied to the system, where the free ends of two metallic wires are contacted, and the ends are successfully welded together in self-completed manner. This technology is also useful for manipulating a small scale materials. Targeted Application(s)/IndustryJoule heat welding technology enables us to produce the functional elements on the electrode chips, e.g., a free-standing micro-ring and very-thin thermoelectric element (Fig. 2). Moreover, we have developed the technique for characterizing the physical properties of small scale materials (Fig. 3). We hope to conduct collaborative research with a willing company for a practical application of this technology in industry. |

Low temperature reforming of hydrocarbons using metal oxide nanoparticles synthesized by supercritical methodFeaturesOur research group has succeeded in synthesizing various metal oxide nanoparticles with controlled size and exposure crystal planes by using organic modifiers under supercritical water conditions. The oxygen storage/release capacity of those materials in the low-temperature region is very high, and the reforming reaction of oxidative hydrocarbon proceeds at a significant rate. Besides, by combining the supercritical CO2 drying method, we have succeeded in forming a complex in which oxide nanoparticles are dispersed at a high concentration on the surface of the porous material, realizing both high oxygen storage/release capability and stability. Targeted Application(s)/IndustryLow-temperature reforming reaction of biomass wastes, heavy oils, and methane. In the future, it is expected to be a technology that will lead to the construction of a low-carbon society, including CO2-free complete recycling of waste plastics.

[use of waste acid oil]
A Novel Process for Continuous Production of High Quality Biodiesel with Ion-Exchange Resin CatalystsFeaturesWe successfully developed a continuous production process for high-quality biodiesel. This production technology is very simple, just passing through the reactors packed with ion-exchange resins without complicated upstream and downstream processes, which provide additional production cost and environmental stress and the entire process is fully automatic. With this technology, you can easily produce high-quality biodiesel from various cheaper oils with fatty acid content up to 100%. Targeted Application(s)/IndustryThis innovative technology succeeds in solving the serious problems in the current biodiesel production, restriction by shortage of feedstock supply and the unstable quality of biodiesel due to the soap formation. This technology also applies to the production of fatty acid methyl ester, a starting material for surfactant production, which is an important intermediate step in oleochemistry.
