In this exhibition, we will introduce a novel internal strain imaging technology of rubber material using terahertz polarization measurement. Currently, our technology attracts attention as a new non-destructive inspection technology.

(1) Newly developed anti-fouling coating that shows easy removal characteristics for water, food or beverages and (2) Transparent coatings that slip oil and liquid are demonstrated. These technologies will reduce environmental problems and promote energy saving. Practical applications are presented.

Controlled of surface structure for anti-fouling coating.
(1) High durability and high transparency.
(2) Repelling and slipping surface against tiny water droplet.
(3) Application for wide range such as mirror and camera lens etc.
Practical applications are presented.

Metallic materials, such as carbon steel, stainless steel and titanium alloys, are required to have certain desirable properties for practical applications. The aim of our laboratory is to develop a new surface modification processes.

Nanoclusters composed of less than thousands of atoms have potential to novel functional materials based on their unique, size specific properties. We have developed a synthesis system for functional nanocluster dispersion by collaboration with Ayabo Corp.. We introduce recent activity of the development of apparatus and synthetic applications for novel nanomaterials.

Nanoclusters exhibit remarkable functions dependent on their size. We have developed a novel microfluidic reactor with ultra-narrow reaction channels by corroboration with Toshiba Machine Co. Ltd. for fine chemical synthesis of ligand-protected metal nanoclusters. We demonstrated the fine synthesis of metal nanoclusters protected by organic polymers and their applications to catalysis.

Recently, the biocompatible materials have become more important with the development of medical technology. Diamond-Like Carbon (DLC) coating receives much attention as one method of improving biocompatibility of medical devices. We introduce our approaches to the development of DLC coatings and the application of them to medical devices.

Diamond-like carbon (DLC) is a high durable thin-film materials manufactured safely and low cost. DLC shows semiconducting properties by doping other elements and we have been working on its application to solar cell. We introduce our approaches to the development of DLC and application of them to solar cell.

We develop new technologies for nano-scale processing and surface property control of materials in order to create added value for industrial products. We deal with super hard alloys, ceramics, semiconductors, glass, diamond, CFRP, and so on. Recently, we succeeded in generation of nanoparticles and 3D nanostructures for high-capacity lithium-ion battery by laser irradiation on waste silicon sludge.

We develop new fabrication technologies for nano-precision free-form optics and their molds by using ultraprecision machine tools. High-speed surface finishing of optical crystals, such as Si, Ge, ZnSe, CaF₂, etc. has been realized by ductile machining technology. Recently, we succeeded in fabricating ultra-thin Si-HDPE hybrid lenses for dark-field optics and thermography applications.
