Anti-icing/Anti-frosting films, micro reactor (droplets movement control), antibacterial film, and repellent film for hot fluidic foods will be exhibited.

(1) Easy removal coating repels water for food or beverage and (2) Transparent coating slips oil for optical devices. This will reduce environmental problems and save energy. We promote the coating products to practical use.

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

Polymeric materials are usually opaque for visible light, but transparent for terahertz light. We demonstrate a polarization-sensitive terahertz spectroscopy which is very useful to investigate internal anisotropy inside polymeric materials.

We develop new fabrication technologies for nano-precision free-form optics and their molds by using multi-axis numerical control ultraprecision machines. High-speed surface finishing of optical crystals, such as Si, Ge, ZnSe, CaF₂, etc. has been realized by ductile machining technology. Recently, we also succeeded in fabricating ultra-thin Si-HDPE hybrid lenses for future IR devises.

Nanoclusters composed of several to several thousand atoms show remarkable, size-specific catalytic performance. We have developed a fabrication method for ultra-fine metal nanocatalysts by utilizing intensive, size-selected nano cluster source “Nanojima^®” (Ayabo Corp.) and non-destructive immobilization (soft-landing) method.

Nanoclusters exhibit remarkable functions dependent on their size. Liquid-phase, chemical synthesis method enables us to obtain gram-scale nanocluster materials. However, it is difficult to control the cluster size precisely. We have developed a novel microfluidic reactor with ultra-narrow reaction channels (Toshiba Machine Co. Ltd.) for the fine synthesis of nanoclusters.

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.

The biocompatible materials have become more important with the development of medical technology. Surface modification receives much attention as one method of improving various properties of biomaterials. We have developed new biomaterials using Diamond-Like Carbon (DLC) coating. We will introduce about our approaches to the biomedical application development.
