It succeeds in the lithium endofullerene analysis and the quantity synthesis of a high conduction.

Research groups such as the ideal star of the research and development venture (Sendaishi) and Touhoku University succeeded in the quantity synthesis etc. of "Lithium endofullerene" that put one lithium atom on the molecular inside that was called "Fullerene" made of 60 carbon atoms.
The verification lingua with the electrical characteristic the structure is also analyzed. In the both first yield in the world, the application in the industrial field like the organic electronics etc. is expected. Study results were announced the British science dated the 20th magazine nature chemically (electronic version).

The research group puts the lithium in the state of the plus ion in the fullerene by using the plasma space where the atom divides into the plus ion and the electron and is a synthesis lingua. The energy of the lithium ion was controlled, and the quantity synthesis was achieved.

The lithium endofullerene was bonded with the chloride and the structure was analyzed with the X-ray of high intensity on the crystallization lingua. As a result, some lithiums turn out from the fullerene core on the outside. In addition, the movement of the electron is affirmed by the action of the chloride, and it has been understood that it has the electrical characteristic of pathognomonic.

The amount of a possible synthesis went up to 100 conventional tens of milligrams an hour, Manbai, and reached at the level that was able to be actually used as an industrial material by the developed method.

The ideal star established the technology to the quantity synthesis based on study results of Touhoku University. Real professor Hiroshi Tobita (mineralization study) in the Touhoku University graduate school science research course et al. took charge of the separation and refinement and crystallization, and the swamp Expo professors of the Nagoya University graduate school engineering study department (structure) analyzed the clarification of the structure in the photon factory.

The lithium endofullerene is expected that there will be a high electroconductive and characteristic of the speed in the rate of reaction etc. to light, and when the application of the n type semiconductor that becomes the material of the organic solar cell, the ultra high density memory, the organic transistor, and the nanosize to the switch etc. can be expected, is Iu.

The ideal star has the developments such as stringy solar cells and sensors done in earnest besides the lithium endofullerene will be provided for a domestic and foreign institution in the future. President Yasuhiko of Kasama speaks, "Cooperation has already been percussed from foreign countries, and it is accelerated make to the business".

Mr. Shigekazu of Takashima of Mitsubishi Corp. global environment business development division Nanotectemuredar that advances making of the fullerene an industry｢It is epoch-making that the venture business completed the raw material of a super-leading edge with a difficult development by the industry-university-government cooperation as for the large company. It is expected for the research to extend to the world, and to develop into the materials revolution. ｣It specifies it.

National environment laboratory of chemical pollution that examines it with register mark and collection calling

The register mark is captured in nationwide various places, and the extension of contamination with the chemical substance is examined.
National Institute for Environmental Studies is planning "Register mark investigation". It is Iu to ask the civilian for cooperation in the collection through the homepage etc. besides the environmental study institution in 28 places participates from Hokkaido to Okinawa, and to analyze a lot of register marks.

It is Yasuyuki Shibata it, chemical environment research area length of National Institute for Environmental Studies, and team of Yoshikane Hicariyou Posdocferor that plans. The examined chemical substance is organic fluorine compound "PFOS" not decomposed easily.

As for PFOS, clothes etc. have been used for the raw material of the fire extinguishant of the surface finishing that sheds water and the foam. However, it has been decided to make it to control subjects in the Conference of the Parties of the Stockholm treaty concerning Persistent Organic Pollutants that are specified the hazardousness such as causing the liver injury in recent years by the animal study, and were opened in May, 2009.

The research team is accumulated this material by the Tenodera angustipennis, the register mark, and the spider and pays attention to Yasui. It has been understood to be able to grip an average pollution status about the range with all sides of the number of one-kilo if the discussed consequence and the maturing register mark are chosen and analyzed.

As for the analysis object, it is scheduled to narrow it to five-kind level such as Orthetrum albistylum speciosum and Sympetrum infuscatum. It is necessary to collect several a point-10. Shibata area length｢It investigates in October in August. I want to ascertain the country though it doesn't know what place is especially contaminated. ｣It speaks.

To verification mouse's sperm building in mammal's pregnancy and space

The Institute of Physical and Chemical Research accrual and the regeneration science integrated study center of the experiment that carries mouse's sperm to space to search for the pregnancy in mammal's space and the possibility of birth, is fertilized after the earth returns, and examines the influence of the radiation and gravity The research team such as (Kobeshi Chuoku) is planning. It becomes the first case where the mammal is born from the germ cell put on space in the world if aiming at the achievement in about fiscal year 2012, and succeeding.
(Kanai Tsuneyuki)

The experiment that examines the influence that the space environment gives to mammal's breeding and accrual is a little.
The former Soviet Union was not able to launch Rattus norvegicus var. albinus's victory or defeat with the rocket in 1979, to give birth to several, and to give birth to the pregnancy lingua.

Team leader Teruhiko Wakayama (43) at the same center et al. artificially made the space with little gravity last August, worked on the experiment that outside of the body fertilized the mouse in that, were inferior the growth of "Early embryo" in which the oosperm had started fission compared with usually, and announced the consequence that the birth rate decreases to the half.

To try in actual in addition space, the experiment that carries the sperm to coming" ..Japanese building ".. is planned about the International Space Station. It is discussed to preserve for a long term separately for what covered with the material that doesn't pass the radiation easily and the one not so on the freeze-dried (vacuum freeze dry) processing lingua, and to compare the sperms.

It was elected to the experiment candidate (19 themes in total) whom Japan Aerospace Exploration Agency transported by uninhabited fueling plane "HTV" of Japan and Soyuz spaceship of Russia in March this year.
The person in charge｢The idea is novel, and a lot of equipment is not needed. The feasibility is very high. ｣It makes it. 

Leader Wakayama speaks, "If the experiment on the sperm succeeds, I want to achieve it the breeding of the mouse where it lives in space".
