Note:
“Great Solution to "Hydrogen Embrittlement Problem"”, published on July 6, 2010, has been rewritten into this article.
The reasons for this are:
1) Description of the previous article is unsatisfactory because the time allowed for me to write was insufficient.
2) The number of accesses to the article is relatively large.
**************************
Hydrogen embrittlement: When a metal is exposed to hydrogen, the hydrogen enters into the metal and the metal is brittle and fractured.
Discovery: When an extremely large amount of hydrogen was made to enter a metal material, a fatigue strength characteristic of the material was considerably improved.
Discovered by HYDROGENIUS = Research Center for Hydrogen Industrial Use and Storage, located at Ito-Campus of Kyushu University
The discovery denies the explanation of the “hydrogen embrittlement” thus far made.
Much research efforts have been made to elucidate a mechanism of the hydrogen embrittlement for a long time in the world. Some theories to explain the hydrogen embrittlement phenomenon have been proposed. This phenomenon has not yet been elucidated, however. It is sure that this fact has impeded real commercialization of the products using hydrogen gas.

Sulfur-Doped Fe-Te Says “I Need More Wine”
NIMS recently made an interesting discovery on the superconductivity development of specific materials.
Discovery: A sulfur-doped iron- tellurium compound （FeTe1-xSx）, which is synthesized by the solid-state reaction process, was simmered in alcoholic drinks for 24 hours. The temperature was about 70 degrees of centigrade. The onset of superconductivity was observed at about 8 K (265 degrees below zero). The drinks used were red wine, white wine, beer, sake, shochu, and whisky. Of those drinks the red wine presented the largest superconducting volume fraction.
At a party, Dr. Takano was inspired to use drinks to cause the material to develop superconductivity. Isaac Newton reached his theory of gravitation when he was hit with (??) ａ falling apple from a tree. It seems that there is a rule that the discovery occurs outside the laboratory.
