Outline

This project aims to create basic technologies for the development of an innovative three-dimensional display. The basic technologies include: 1) the synthesis of helical conjugated polymers in external-stimulus-responsive chiral liquid crystals, 2) the synthesis of helical oligomeric molecules bearing high circularly polarized luminescence (CPL), 3) the creation of measurement techniques for evaluating CPL intensities and dissymmetrical factors in thin film and the solid state, 4) the fabrication of CPL devices and light-emitting diodes based on CPL materials, and 5) the elucidation of the excited states of CPL materials and the establishment of guiding principles for molecular designs.

Innovative Vibrational Spectroscopy based on Tailorable Infrared Sources

Grant No.：JPMJCR2002

Research Director :Satoshi Ashihara

Outline

We create a new infrared light source technology to provide a major breakthrough in vibrational spectroscopy. By taking advantage of the high brilliance of infrared coherent light based on a novel solid-state laser and the degree of freedom of electric field waveforms, we will create highly-sensitive vibrational spectroscopy to capture trace amounts of molecules and chemical reaction control methods to promote desired reactions.

Keiko Kimura	Representative Director APCO. Ltd.
Hiroyuki Futamata	Professor Research Institute of Green Science and Technology Shizuoka University

Outline

We develop super resolution cell-function imaging and cell-stimulation techniques with combination of optical and electron microscopes. In this research atmospheric condition for living biological cells and vacuum condition for electron irradiation are separated with a thin film. Focused electron beam penetrates the thin film and electrons are irradiated through the film to living biological cells. The focused electron beam achieved high resolution and excites the fluorescence and stimulation for the cells. We analyze fundamental properties of living cells with electron irradiation and mechanism of emission of photons. This technique is promising for high resolution imaging of biological cells and analysis of functions of cell membranes.
