JOINT STUDIES PROGRAMS

As one of the important functions of an inter-university research institution, IMS undertakes joint studies programs for which funds are available to cover research expenses as well as travel and living expenses of individuals. The proposals from domestic scientists are reviewed and controlled by an inter-university committee. The programs are carried out under one of five categories:

  1. Joint Studies on Special Projects (a special project of significant relevance to the advancement of molecular science can be carried out by a team of several groups of scientists).
  2. Research Symposia (on timely topics, organized by collaboration between outside and IMS scientists).
  3. Cooperative Research (carried out by outside sientists with collaboration from an IMS scientist).
  4. Use of Facility (the Computer Center, Laser Research Center for Molecular Science and other research facilities at IMS are open to all researchers throughout the country).
  5. Joint Studies Programs Using UVSOR Facilities.
    A. Special Projects, B. Cooperative Research Projects, C. Invited Research Projects, D. Use-of-UVSOR Projects.

In the fiscal year 1996, the numbers of joint studies programs accepted for categories (1) - (4) were 2, 10, 92 and 252, respectively, and those accepted for subcategories (5)A - (5)D were 3, 24, 1 and 147, respectively.


(1) Special Projects

A Advanced Research of Carbon Clusters

The aim of this research is to search for new families of fullerene materials and to obtain a comprehensive understanding of various unique features of fullerene materials. The research was carried out over a wide range covering physical chemistry, solid state physics, surface sciences. To accelerate our collaborative project we have held a workshop on 21 and 22 December, 1996.

B Oxygen Molecular Conversion with Chemical Models of Metalloenzymes

Contributors:
Yoshinori NARUTA (Kyushu Univ.), Yoshito WATANABE, Fumito TANI (Kyushu Univ.), Alain KOSSANYI (Kyushu Univ.), Kanako ICHIHARA (Kyushu Univ.) and Takao SASAKI (Kyushu Univ.)

This research project aims at the molecular-level understanding of the reaction mechanism of metalloenzymes participating the molecular conversion of oxygen, i. e., cytochrome P-450, cytochrome c oxidase, and oxygen-evolving complex in plant PSII by use of artificial chemical models and the developing new reaction systems with these catalysts.

C Multi-Functional Molecular Solids with p-d Electronic Structures

Contributors:
Susumu KITAGAWA (Tokyo Metropolitan Univ.), Hayao KOBAYASHI, Masahiro YATASHITA (Nagoya Univ.), Norimichi KOJIMA (Univ. Tokyo), Toshiaki ENOKI (Tokyo Inst. Tech.) and Hiroshi KITAGAWA (JAIST)

Recently electric, magnetic and optical properties of molecular solids have attracted the increasing interest. Up to now, these three properties of the molecular solids have been studied separately. The aim of this research project is the design, development and characterization of new molecular solids exhibiting multi-functional properties. Since the nontrivial electronic properties of molecular solid are always originated from the incompletely occupied molecular (or atomic) orbitals, the systems with two types of incompletely occupied orbitals will be examined systematically.

(3) Cooperative Research

This is the most important programs IMS undertakes for conducting its own research of the common interest to IMS. During the first half of the fiscal year of 1996 ending on September 30, 36 outside scientists joined this program and during the second half, 56 outside scientists did. The names and affiliations of those collaborators are found in Research Activities.


(4) Use of Facilities

The number of projects accepted for the Use-of-Facility Program of the Computer center during the fiscal year 1996 amounted to 201 (719 users) and computer time spent for these projects is 51551 hours (converted to the HITAC M-680H time), and amounted to 70% of the total annual CPU time used. The number of projects accepted for the Use-of-Facility Program of the Instrument Center during the fiscal year 1996 amounted to 51 (154 users).


(5) UVSOR

In the UVSOR Facility with the 750 MeV electron storage ring, there are nineteen beam lines available for synchrotron radiation research. The Experimental Facility of each beam line is discribed in the UVSOR ACTIVITY REPORT 1997. Under the following programs, a number of SR studies have been carried out by many users outside and inside IMS: A the UVSOR Special Projects, B the UVSOR Cooperative Research Projects, C the UVSOR Invited Research Projects, and D the Use-of-UVSOR Projects.

A UVSOR Special Project

In the fiscal year of 1996, the following UVSOR special projects were carried out.

  1. Title: Construction of multilayer monochromator system for photochemical reactionsBeam Line: 4ARepresentative: Tsuneo URISU (IMS)
  2. Title: Construction of glancing incident monochromator at BL2B2Beam Line: 2B2Representative : Koichiro MITSUKE (IMS)

B UVSOR Cooperative Research Projects

Under this joint-study program, many synchrotron radiation experiments have been carried out with the beam lines of in-house staff in cooperation with scientists who were invited from other institutions. The total number of the projects in this category was 24 in the fiscal year of 1996.

C UVSOR Invited Research Projects

Under this joint-study program, several scientists were invited from other institutions of help for construction of new beam lines and improvement of the UVSOR storage ring and others. The total number of the projects in this category was 1 in the fiscal year of 1996.

D Use-of-UVSOR Projects

Ten out of the total of nineteen UVSOR beam lines are available for general users outside and inside IMS for their synchrotron radiation studies in the field of molecular science. The total number of the projects in this category was 146 in the fiscal year of 1996.
