[Polymer electrolyte fuel cell]
Surface scientific approach for developments in fuel cell's catalystsFeaturesFrom 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. Targeted Application(s)/IndustryGraduate School of Environmental Studies

[Polymer film]
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. |

[positron]
Analysis and Function Elucidation of Fine Clusters and Defects in Materials Invisible by Electron MicroscopyFeaturesIt is well known that nano-scale impurity/solute clusters, defects, defect clusters and their complexes affect the mechanical and electrical properties in materials. However, it is very difficult to observe these objects even by state-of-the-art electron microscopes. We overcome the difficulty by employing noble two techniques: laser three-dimensional atom probe (3D-AP) technique and positron annihilation spectroscopy (PAS). Laser 3D-AP can map out each atom in various materials (metals, semiconductors, insulators) in three-dimensional real space with nearly atomic scale resolution. PAS can detect vacancy-type defects and defect-impurity complexes very sensitively. Targeted Application(s)/IndustryBy combining these methods, we are going to reveal the functions of the fine impurity clusters and defects to the materials: developments of new nano-structured materials, the mechanism of degradation of aged structural materials, the fall in the yield of semiconductor device production, and developments of quantum devices etc. |

[Positron Emission Tomography (PET)]
Molecular Imaging from Basic Research to Clinical ApplicationFeaturesMolecular Imaging and its Application to Drug Development: Positron emission tomography (PET) comprises the administration of carbon-11- or fluorine-18-labeled tracers to human subjects in order to describe the concentration-time profile in body tissues targeted for treatment. As PET involves the administration of only microgram amounts of unlabeled drug, the potential risk to human subjects is very limited. Consequently, required preclinical safety testing is reduced as compared to conventional human studies. Targeted Application(s)/IndustryPET molecular imaging studies are gaining increasing importance in clinical drug research, as they have the potential to shorten time-lines and cut costs along the critical path of drug development. We have developed several PET tracers for molecular imaging such as amyloid imaging and central nervous system drug research at Tohoku University, Japan. We will present the recent progress and strategy of "PET molecular imaging" in order to accelerate drug development.

[Prediction of Fractures]
Prediction and Prevention of FracturesFeaturesWe have been developing methods for explicating the dominant factors that determine the physical and chemical properties of materials and stacked structures used in human societies. Since the number of element atoms which consists of advanced materials has been increasing, and the crystallographic structure of the materials has become very complicated, both the various properties and reliability of the materials fluctuate significantly in nano-scale, and thus, deteriorate easily due to the local damages of the materials. Targeted Application(s)/IndustryTo design the optimal structure, composition of materials, and the fabrication process of both materials and stacked structures, we are going to develop a method of analyzing the atomic structure of thin film materials based on quantum mechanics and experimental methods for measuring material properties, atomic scale damage or defects in nano-materials.

[prevention]
Biomarker Development and Preemptive Therapy of Alzheimer's DiseaseFeaturesOver the past 20 years, our understanding of molecular pathology of dementia and AD has dramatically deepened, and new biomarkers including amyloid PET and cerebrospinal fluid (CSF) amyloid42/tau as well as therapeutic strategies have been developed. However, clinical trials of disease-modifying drugs in mild to moderate AD were unsuccessful or were halted due to serious adverse drug effects. Targeted Application(s)/IndustryThese results strongly suggest that disease-modifying therapies should be started much earlier before a widespread neuron death will occur. We hope that early detection and prevention with preemptive therapy may lead to a success of fighting AD. Department of Geriatrics and Gerontology, Institute of Development, Aging and Cancer
