Antifouling coating film with superhydrophobic and superoleophobic properties
Associate Professor SHIRATORI, Seimei
Department of Applied Physics and Physico-informatics
An antifouling coating film with superhydrophobic and superoleophobic properties was fabricated. The film cannot be soiled by liquids with various surface energies and viscosities, including cooking oil, soy source, mayonnaise, and ketchup. Further, the transparency and durability of the coating film was improved for practical use.

Development of wavelength converters using nanophosphors
Research Associate TAKESHITA, Satoru
Department of Applied Chemistry
We focus on wet chemical synthesis and applications of the fluorescent nanoparticles, i.e., nanophosphors. Our nanophosphors have unique physicochemical properties in comparison to micron-sized phosphors, and in the near future, the former can be applied as novel wavelength conversion materials in the fields of solar cells, lighting, and bioimaging.

New Superconducting Materials and Fabrication of Superconducting Wires
Associate Professor KAMIHARA, Yoichi
Professor MATOBA, Masanori
Department of Applied Physics and Physico-informatics
Several metals, alloys, and compounds exhibit a superconducting phase at low temperatures. Our primary and secondary purposes are, respectively, the discovery of new high-Tc superconducting materials and the development of superconducting cables using a powder-in-tube process.

Silicon Nanotechnology
Professor ITOH, Kohei
Department of Applied Physics and Physico-informatics
Making small structures with silicon is investigated. Very narrow silicon wires are produced and their applications are being explored.

High-sensitive nanoscale magnetometry using diamond crystals
Associate Professor HAYASE, Junko
Department of Applied Physics and Physico-informatics
A nitrogen-vacancy center in a diamond is an attractive candidate for high-sensitive nanoscale magnetometry, i.e., nanoscale imaging of living cells and magnetic materials. We show the investigation in collaboration with AIST for realizing high-sensitive nanoscale magnetometry using a high-quality diamond ultrathin film.

Development of long wavelength light emission based on firefly luminescence
Professor NISHIYAMA, Shigeru
Department of Chemistry
Red light emission, which may have the potential for use in new medical tools, was investigated by mimicking firefly emission. Further, new luciferin derivatives were produced by means of an organic synthetic procedure.

Development of Actual Devices Using Electro-adhesive Sheet
Professor AOYAMA, Tojiro
Department of System Design Engineering
We have developed the functional material of “electro-adhesive sheet” whose adhesive property of the surface can be changed according to applied electric field. The EA sheet is possible to be applied to the brake, clutch, fixture mechanism and so on. We will exhibit the practical application devices in our booth.

Surface Engineering for Structural Steel
Professor KOMOTORI, Jun
Department of Mechanical Engineering
Many surface-modification treatments are performed on metal surfaces used in machines and constructions, with the aim to functionalize and improve the metal properties, including fatigue strength, corrosion resistance, and wear resistance. Herein, we discuss some of the surface-modification processes developed recently to improve such properties.

Ultraprecision Micro-Nano Manufacturing
Professor YAN, Jiwang
Department of Mechanical Engineering
To create new products with high added value, we are conducting research and development on high-accuracy, high-efficiency, and resource-saving manufacturing technologies throughmicro/nanometer level material removal, deformation and property control. Our recent research focuses include ultraprecision mechanical fabrication, micro-nano forming/imprinting, electricalmachining, laser machining, laser Raman spectroscopy, and laser defect-repairing.

Influence of phase separation of sunscreens on the evaluation of their UV shielding property
Professor ASAKURA, Kouichi
Department of Applied Chemistry
The effectiveness of sunscreens is due to their UV shielding property. Sunscreens are generally composed of many ingredients. Herein, we present a problem with the evaluation of the UV shielding property of sunscreens when they undergo phase separation or when there is a change in the phase-separation structure.
