Effects of Hydrogen on the Vacancy Formation in Magnesium
Autor: Masuo Yamada, Takehide Senuma, Moritaka Hida
Publikováno v: MATERIALS TRANSACTIONS. 49:2006-2011
Quenching and annealing experiments with electric resistivity measurements were applied to magnesium to investigate the formation of thermal vacancies. Two specimens made from materials differing in impurity contents were examined. One of the specime

Autor: Harumi Oshima, Norihisa Kawamura, Isao Saito, Masuo Yamada
Publikováno v: Eisei kagaku. 36:219-225
A simple and rapid method was developed for the analysis of total germanium (Ge), inorganic Ge (GeO2) and organic Ge (β-carboxyethyl germanium oxide ; CE-Ge) in Ge-containing health beverages. In order to determine total Ge, the sample was digested
