52	Novel Methods for Large-scale Synthesis of Nanoclusters
	Professor NAKAJIMA, Atsushi* Assistant Professor TSUNOYAMA, Hironori Department of Chemistry * KiPAS Principal Investigator
Novel methods for large-scale and fine synthesis of nanoclusters, super-small particles of sub-bulk size which have unusual and various functionalities, have been developed. 1. High power magnetron sputtering for nanoclusters 2. Micro-fluid reactor for liquid phase synthesis of nanoclusters protected by organic ligands

53	Stains hardly adhere on surface: Easy removable coating
	Professor SHIRATORI, Seimei Department of Applied Physics and Physico-informatics
(1) Easy removal coating for food or beverage and (2) easy removal coating for high viscous liquid such as concrete will be demonstrated. This will reduce environmental problems and save energy. We promote the coating products to practical use.

54	Ultra-Precision Micro Fabrication for New Materials
	Professor YAN, Jiwang Department of Mechanical Engineering
We develop new technologies for micro/nano-scale shape generation and surface property control of new materials in order to improve the functional capability and added value of industrial products. Besides mechanical fabrication, we also use electrical/chemical effects, laser and ultrasonic vibration to innovate the machining technologies for materials such as super hard alloys, semiconductors, glass, diamond, CFRP, and ceramics.

55	Development of pulverization disks using diamond films deposited by chemical vapor deposition
	Professor SUZUKI, Tetsuya Department of Mechanical Engineering
Micro through-hole forming disks are used in pulverization devices. These components are core parts for particle pulverization contributory to economical use of fuel. However, conventional single-crystal diamond disks cost a lot. To reduce the cost of the disks, we develop ceramic disks coated with diamond films.

56	The flexible solar cell device using Diamond-like carbon film
	Professor SUZUKI, Tetsuya Department of Mechanical Engineering
The solar cell is effective to solve the energy problem. However, it is necessary to reduce the production cost and to expand the application. The solar cell using Diamond-like carbon film (DLC solar cell) meets these demands. In this booth, we introduce our research on DLC solar cell.

57	Coating technology of thin film under atmospheric pressure to improve productivity and its application to rails, automobiles and packagings industries
	Professor SUZUKI, Tetsuya Department of Mechanical Engineering
Synthesis technology of thin film is used in various fields such as automobile and packaging industries. Atmospheric-pressure plasma allows large-area and short-time treatments, which lead to productivity improvement. We introduce the characteristics and applications of amorphous carbon and silica based films synthesized under atmospheric pressure.

58	Next-generation technology for developing medical device using biocompatible Diamond-Like Carbon coating
	Professor SUZUKI, Tetsuya Department of Mechanical Engineering
The biocompatible materials have received much attention as the improvement of medical technology. Surface modification such as diamond-like carbon (DLC) coating is one method of improving various properties of biomaterials. We previously reported that fluorinated DLC markedly enhanced biocompatibility. We will introduce about our approaches to the biomedical application development.
