A Microwave-Based Non-Destructive Testing Method for the Long Range Inspection of Metallic PipeFeaturesWe are developing a non-destructive testing method for the long range rapid inspection of metallic pipe using microwaves. The method propagates a microwave inside a pipe, and evaluates flaws appearing at the inner surface of the pipe on the basis of the reflection and transmission of the microwave. The method does not require scanning probes unlike conventional non-destructive methods, which enables one to inspect a pipe quite quickly. Our experimental validations have demonstrated the effectiveness of the method using a pipe as long as 30 m. Targeted Application(s)/IndustryThe NDT method proposed here is applicable when many pipes are inspected or conventional methods are not available due to pipe length and its configuration.

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.

Advanced Control of Microstructure and Property of Structural Metallic MaterialsFeaturesMicrostructure represents various kinds of heterogeneities in the metallic materials, i.e., grains, component phase, lattice defects and chemical inhomogeneity such as impurity/alloying elements. It can be modified through control of phase transformation/precipitation and deformation/recrystallization by adjusting compositions of materials and/or through processing routes (heat treatment, deformation). Such expertise in micro/nanostructure control is very important in production of current materials from viewpoints of energy saving and recycling in structural materials such as steels and titanium alloys. Targeted Application(s)/IndustryPossibilities to establish new functions (e.g., superplasticity, shape memory/superelasticity) as well as superior mechanical properties (e.g., ultrahigh strength with high toughness/ductility) is also explored. |
Advanced die casting process computing with solidification phenomenaFeaturesDie casting is a method of mass-producing high-precision castings in a short time by filling the mold with molten metal at high pressure and high speed. Since solidification is completed quickly under high pressure, various defects peculiar to die casting occur. Significantly, the casting cavity has a high incidence in die casting, and it is a factor that hinders the quality. Therefore, a numerical approach to the die casting process is expected to prevent these problems, and the information obtained from the numerical analysis is expected to be reflected in the casting plan to reduce the number of prototypes, the lead time to product development, and the cost. In this study, a multiphase flow analysis with solidification phenomena of molten aluminum inside mold was conducted for a high-pressure die casting process of the throttle body.

A variety of optically active compounds has been synthesized through the development of highly stereoselective reactions using these catalysts. Targeted Application(s)/IndustryThe 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.

Advanced Recycling Process and Development of Environmental Preservation TechnologiesFeaturesA large amount of resources are utilized in the base metal production processes such as iron & steel, copper and zinc. Therefore, it is important to improve such process efficiencies for solving the energy and environmental issues. On the other hand, the increasing production in developing countries leads to the depletion of high-grade resources. In this laboratory, basic researches for integrated processes from pretreatment, metal manufacturing, refining and recycling are made for the development of new processes with high efficiency and low environmental load by utilizing "low-grade" resources.

Amyotrophic lateral sclerosis (ALS),Muscular dystrophy,Distal myopathy with rimmed vacuoles (DMRV)/ hereditary inclusion body myopathy (hIBM)FeaturesDistal myopathy with rimmed vaculoles (DMRV) / hereditary inclusion body myopathy (hIBM) is an autosomal recessive disorder characterized clinically by the preferential involvement of the tibialis anterior muscle. It is known that the disease gene underlying DMRV is GNE, encoding glucosamine (UDP-N-acetyl)-2- epimerase and N-acetylmannosamine kinase, two essential enzymes in sialic acid biosynthesis. Decreased sialic acid production causes muscle degeneration. Muscle atrophy and weakness are completely prevented in a mouse model of DMRV after treatment with sialic acid metabolites orally.

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. |
