[Radiophamaceutical Chemistry]
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.

[reconfigurable circuit]
PVT-Variation-Aware VLSI System Based on Nonvolatile-Device/MOS-Hybrid CircuitryFeaturesNonvolatile devices, which can remain stored data without power supply, are generally used for ROM (Read-Only Memory) to store boot programs (the information to start up the computer and the basic instructions that operate it) in computers. One attractive feature is that it does not consume any static power while it remains stored data. ‘Nonvolatile logic' is a novel logic style that a nonvolatile device is used for not only a nonvolatile storage element such as ROM but also a logic-circuit element which is the basic component of a CPU and an entire system. By using the nonvolatile devices as storage elements of circuit-configuration information, we can realize a process-variation- aware logic circuit with small hardware overhead. Targeted Application(s)/IndustryThe proposed technique is effective for implementing high-performance and highly-reliable LSI fabricated with cutting-edge process technology. We expect we can conduct effective collaborative research in highly reliable VLSI-systems fields. Research Institute of Electrical Communication

Room temperature bonding using thin metal films (Atomic Diffusion Bonding)FeaturesAtomic diffusion bonding of two flat wafers with thin metal films is a promising process to achieve wafer bonding at room temperature. High surface energies of metal films and a large atomic diffusion coefficient at the grain boundaries and film surfaces enable bonding at room temperature without unusually high loading pressure. This technique, which enables bonding of any mirror-polished wafer, is gaining wider use for fabricating optical and electrical devices. Moreover, bonding of mirror polished metals and polymer sheets can be achieved, which further extends the application of this bonding technique. Targeted Application(s)/IndustryOptical, power and electrical devices, MEMS, bonding of polymer sheets, metals, and ceramics for precision mechanical equipments.

[Recycle]
Monomer-Recycle System of Biodegradable Plastics by Industrial Fungal Fermentation and Application of Fungal Biosurfactant Proteins to Nanoparticles for Medical UseFeaturesIn Japan, solid-phase fungal fermentation systems using the industrial fungus Aspergillus oryzae have been extensively used for producing fermented foods such as soy sauce and sake; the annual production volume of the products is over one million tons. The efficient enzymatic hydrolyzing systems are expected to be applicable to biological recycling of biodegradable plastics. We found that A. oryzae can effectively degrade polybutylene succinate-coadipate (PBSA) by the combination with an esterase (cutinase) CutL1 and novel surfactant proteins, RolA and HsbA that are attached to the surface of PBSA and then recruit CutL1. The recruitment of Cutl1 by the surfactants stimulated PBSA degradation. Targeted Application(s)/IndustryThe fungal biosurfactant protein is applicable to industrial recycling of biodegradable plastics and to production of immune-response free nano-particles for medical use. |
[Recycling]
Development of Recycling Technology for High-Water Content Sludge by Using Fiber MaterialsFeaturesThe recycling rate of construction muds and sludge is very low because the water content of these muds is very high and direct reuse of them is very difficult. Therefore, a new recycling technology for high-water content sludge has been developed in this laboratory. This technology is called "Fiber-Cement-Stabilized Soil Method", and it uses fiber materials and cement. The main feature of this method is to mix the fiber materials with the sludge, and the fiber materials included in the soil produce several geotechnical merits. Targeted Application(s)/IndustryThe modified soils produced by this method can be used as ground materials for reinforced embankment of the river bank and soil structures because they have several features such as high failure strength, high failure strain high durability for drying and wetting and high dynamic strength.
