- Surface modification method to improve fatigue strength has been developed using cavitation impacts, which are normally causes severe damage in hydraulic machineries. The method was called "cavitation peening". In order to make clear the mechanism, a load controlled plate bending fatigue test machine was developed. It was proved by using the test machine that the threshold level of stress intensity factor was improved about 1.9 times by cavitation peening. The mitigation of hydrogen embrittlement by cavitation peening was also improved.

- We developed both pH and Cl- imaging plates, which can visualize the pH and Cl- concentration on metal surfaces in acidic environments. The pH range is from 3.0 to 0.5, and Cl- concentration up to 4 M can be measured. Fluorescent dyes are successively used for pH and Cl- imaging in the field of biology, but their sensitivity tends to be insufficient in acidic and/or highly concentrated chloride solutions. A glass plate with a sol-gel sensing layer, which contains a pH indicator or a Cl- sensitive florescent dye was fabricated and validated using the solutions with various pH values and Cl- concentrations. Changes in the pH and Cl- distribution on stainless surface in an acidic environment were measured quantitatively.

The newly developed imaging plates can be used to investigate the mechanism of various chemical reactions, such as corrosion, which occurs in an acidic environment. Micro-flow imaging using our sensing technique will be a promising approach to understand the catalytic chemistry of metal surfaces.

- The Yoshioka Laboratory works on the recycling of various polymers by thermal and wet processes. Plastics such as poly(ethylene terephthalate) (PET), polyvinyl chloride (PVC), and high impact polystyrene (HIPS) cause serious problems during their recycling for the recycling process and the environment. However, these materials can also be seen as a resource for new materials. The decarboxylation of PET results in high yields of benzene that can be used as a chemical feedstock. Another important feature is the dehalogenation of flame retarded plastics and PVC. Dechlorinated plastic waste can be an important source for hydrocarbons, which can be used as fuels and chemical feedstock. The chemical modification of PVC offers the possibility of new materials with new properties. Modified PVC can be used as antibacterial material or as a material with ion exchange properties. The removal of brominated flame retardants from HIPS leads to higher recovery rates of styrene during thermal processing. When a wet process is used, the resulting flame retardant free HIPS can be reused.

We are eager to help companies to overcome their problems during recycling and recovery, and provide solutions for the treatment of waste materials.

- Maximal resection and functional preservation, are often conflicting, but are both important factors to improve patient’s quality of life. Pulsed jet system is designed to achieve this goal by removing lesions without impairing small diameter vessels (100 μm - ). Standardization and specialization of surgical procedures is expected to achieve more easily compared to conventional surgical device using pulsed jet system. We have already reported significant increase of tumor removal rate, significant reduction of intraoperative blood loss and operation time in difficult lesions in the vicinity of sella turcica and skull base through expanded transsphenoidal approach. The system can eject small amount ( - 2 μl) of high speed liquid (- 50 m/s) for minimally invasive surgery, such as endoscopic, catheter, and microscopic surgery. The system is now under stage to expand clinical application outside the field of neurosurgery, and we are expecting new collaboration who can deal with increasing safety, effectiveness, differentiation from conventional instruments, accessibility.

By utilizing the LC resonant magnetic marker due to the latest magnetic engineering technology, we have achieved a magnetic wireless system which could be used even in a shielded space such as oral cavity by applying a magnetic field from outside the body. By using the infrared reflective markers of small and light, we have also succeeded in developing an optical system capable of synchronous real-time measurement at up to 50 locations at 250 hertz.

- Treatment with hot-compressed or subcritical water is an attractive process for converting food waste into valuable materials. Water is an environmentally acceptable solvent and is cost effective; thus, hot-compressed water has recently received attention as a medium for resource recovery from waste. We chose fish gelatin as a model of marine food waste (especially fish skin fraction), and we determined the optimum conditions for the degradation of fish gelatin with hot-compressed water between 160 and 240 °C at 2 MPa. These conditions were optimized in terms of maximizing the concentrations of specific degradation products, such as peptides, and ACE inhibitory.

- Using laser fabrication, we are developing techniques to enhance material surface properties and functionality. For example, to create a functional interface, we aim to clarify, by way of simulation and experimentation, the phenomenon that occurs when the surface of a material is irradiated using a laser beam.
- We expect that the results of our research will be widely applicable, including biomedical devices.
- ■ Creation of biocompatible surfaces
- Materials used for artificial organs, vessels, and other bio-implants require excellent tissue and cell biocompatibility. Therefore, we are exploring the creation of biocompatible surfaces using a new laser irradiation process in this study.
- We have succeeded in imparting a biologically active function to titanium-based materials by applying the laser irradiation technique. When such a material that has a biologically active function is inserted in a living body, hydroxyapatite (the principal constituent of bones and teeth) precipitates on the surface. Using the laser irradiation technique, we can manufacture bone-adherent implants, and we envisage their application to artificial joints or dental implants.
- This research aims to discover such breakthrough solutions for biomedical applications using the laser irradiation technique.
