Design of Photofunctional Materials

-Photocatalytic transformations by Sunlight-

Prof. Takayuki Hirai, Associate Prof. Yasuhiro Shiraishi

Our group aims at the design of photofunctional materials, especially for optical sensors and photocatalysts driven by light energy. The optical sensors include the chemosensors that quantitatively detect trace levels of environmental pollutants by absorption and fluorescence analysis. The photocata...

Chemistry–Biology Combined Research

Chemical Approach to DNA Damage and Repair

Prof. S. Iwai, Associate Prof. I. Kuraoka, Assistant Prof. J. Yamamoto

We are studying nucleic acids (DNA and RNA), as well as proteins that interact with them, from a chemical point of view. DNA is an organic compound that has a string of carbon atoms, and undergoes various chemical reactions (DNA damage) within a living organism. Consequently, alteration of the chem...

Mathematical Analysis in Fluid and Gas Dynamics

Differential Equation Group Prof. Takayuki Kobayashi

The mathematical analysis of fluid dynamics, the study of incompressible viscous fluid (Navier-Stokes flow), and the study of compressible fluid which describes the motion of the gas, has been actively carried out. The mathematical analysis of the Navier-Stokes flow began from the existence theorem ...

Ecofriendly thermoelectric materials for reuse of huge waste heat from LSI

Professor, Yoshiaki Nakamura

Thermoelectric materials convert waste heat to electric energy, which can lead to an ideal energy source. To enhance the thermoelectric performance, it is needed to develop the material that has high Seebeck coefficient, high electric conductivity and low thermal conductivity. However, it is difficu...

On the flow phenomena including gas-liquid interface

Fluids Engineering Research Group: Prof. Kazuyasu Sugiyama, Assoc. Prof. Hironori Horiguchi, Assist.

In liquid flows, the pressure is spatially varied according to the local flow state. Cavitation is the formation of bubbles in the region where the pressure is lower than the saturated vapor pressure. Cavitation inevitably occurs in high-speed fluid machineries or systems, and often makes negative e...

The skeleton of fluid turbulence

― approach by simple invariant solutions to the problem of turbulence ―

Genta Kawahara, Professor

The states of fluid motion are generally classified into laminar and turbulent flow. The turbulent flow exhibits spatiotemporally chaotic behaviour and its details repeat neither in space nor in time. Most of fluid motion seen in daily life, such as water flowing out of a fully-turned-on tap and vor...

Computational Nano-Materials Design on Green Energy

Large-scale electronic structure calculations for magnetic phase-change materials

Professor: Hiroshi Katayama-Yoshida, Assistant professor: Tetsuya Fukushima

Electrons play an important role for macroscopic properties in condensed matter. The electronic structure, which is determined by the many-body Coulomb interaction, leads to novel and fascinating properties, such as ferromagnetism, ferroelectricity and superconductivity.  First-principles calc...
