Associate Professor TSUDA Tetsuya

Assistant Professor UEMATSU Taro

We are developing new materials by manipulating surfaces and interfaces with electrochemical methods. Among them, we focus on ionic liquid that consists of salts and has nonvolatile nature. New analytical techniques for surfaces are developed in combination with electron microscopes, and they are utilized in the development of new types of batteries. Another material of interest is semiconductor nanoparticles that are recently known as fluorophores. Efforts to recognize the nature of nanomaterials are made by looking closely at electrons and photons.

Associate Professor MIZOHATA Eiichi

Assistant Professor Fukuda Yota

Our aim is to understand structure/function relationships of proteins. We visualize their three-dimensional structures at an atomic level by X-ray crystallography. To do this, we crystallize proteins and collect X-ray diffraction data from the crystals at SPring-8 or SACLA, and process the data with computers to reveal the electron-density maps. We then speculate the structure/function relationship and design novel molecules that control its function. Development of small-molecule medicines, the 3rd generation antibody drugs, and improvement of global environment and crop productivity are now in study.

RESEARCH OBJECTIVES
We deal with various types of the topics on nanoscience through the physical organic chemistry approach based on the synthetic chemistry.

1) Chemistry of Curved π-Aromatic Molecules
Bowl-shaped π-conjugated compounds including partial structures of the fullerenes, which are called ""buckybowls"", are of importance not only as model compounds of fullerenes but also as their own chemical and physical properties.Very few buckybowls has been achieved for preparation mainly due to their strained structure. We develop the rational route to the various buckybowls with perfect chirality control using the organic synthesis approach, and investigate their physical properties.

2) Chemistry of Metal Nanocluster Catalyst
We also investigate to develop novel catalytic properties of metal nanoclusters. We focus on the following projects: Preparation of size-selective gold and gold-based alloy nanoclusters supported by hydrophilic polymers and its catalytic activity: Development of designer metal nanocluster catalyst using the highly-functionalized protective polymers.

Research in our group seeks to bring the experience and tactics of strategies of organic methodology development based on synthesis of potential molecules. Especially, our interests are focused on efficient, selective, and environmentally benign methodologies for synthesis of valuable molecules. The new methods have been developed for the synthesis of useful molecules as building blocks for organic synthesis, fullerene derivatives directing toward functional materials, and natural products.

Cellulose is the most common and abundant bioresources, mainly originating from higher plants. We have successfully extracted cellulose nanofibers with widths of 4-15 nm from wood pulps, and have developed cellulose nanofiber-based materials, such as transparent paper, especially for electronic applications.

The industrial application of quantum beam will rapidly expand in the field such as high-volume production of semiconductor devices. Cancer therapy using ionizing radiation has also attracted much attention. In Department of Beam Materials Science, the radiation-induced chemical reaction and reaction field have been investigated using state-of-the-art quantum beam (electron, extreme ultraviolet radiation, laser, synchrotron radiation, X-ray, gamma-ray, ion beam). We have studied the chemical reaction system from the energy deposition on materials to the expression of material function. On the basis of these studies, we have designed a noble chemical reaction system.
