| Research Abstract |
(1) Purpose
In order to improve a highly sensitive and effective analytical technique based on photothermal spectroscopy, a comprehensive investigation on photothermal phenomena should be carried out from the following two points of view.
(1) New possibilities and prospects should be clarified on photothermal spectroscopy.
(2) Basic process in photothermal effects should be investigated to develop new techniques.
(2) Process of investigations
The present project was carried out on five important points of view and on a series of four discussion meetings as described below.
First meetings July 21-22,1995 Tokyo
Second meetings November 23-24,1995 Fukuoka
Third meetings August 20-21,1996 Kyoto
Fourth meetings November 10-11,1997 Tokyo
(3) Results
The results of this project is consisted of individual research efforts and joint discussion.
(1) Basic processes. /// Shape and size effect of small particles (Kitamura, Hokkaido). Detailed analysis of basic process based on new methods (Terashima, Kyoto). Diffusion length with a direct electric field (Toyoda, Elect.& Comm.).
(2) new instrumentation. /// Thermal conductivity in thin films (Hata, Kanazawa). X-ray photothermal spectroscopy using a SOR ring (Masujima, Hiroshima).
(3) Biological applications. /// High sensitive determination on skin (Uchiyama, Tokyo Met.).
(4) Surfacial applications. /// Hydrophobicity on water surface (Ogawa, Kyushu). Liquid-liquid interface (Kawazumi, Kinki). Adsorption isotherm at interfaces (Teramae, Tohoku).
(5) Practical applications. /// Ablation process (Ito, Nagaoka). Frequency dependence of dynamic heat capacity (Kojima, Tsukuba). Slab optical guide (sugitani, Kanagawa). Continuous monitoring of dioxine (Imasaka, Kyushu).
