Publication number: 20110147651Abstract: A method of producing magnesium-based hydrides is provided that can enhance production efficiency while securing safety. An Mg ingot including Mg is cut to make a number of Mg flakes. An accumulated matter made by accumulating a number of Mg flakes are compressed and shaped to form a compressed matter of Mg flakes.

Publication number: 20100209528Abstract: The present invention is for extremely pure solutions of chlorine dioxide, methods for making such solutions and to compositions and methods for storing, shipping and using such solutions. Generally, the chlorine dioxide solutions of the invention are aqueous solutions containing about 2500 ppm or less of total impurities. The chlorine dioxide solution can be prepared by passing dilute highly pure chlorine gas through a bed of substantially solid sodium chlorite and contacting the resulting chlorine dioxide gas with a liquid.Type: ApplicationFiled: November 14, 2006Publication date: August 19, 2010Applicant: CDG RESEARCH CORPORATIONInventors: Thomas Ellsworth McWhorter, Aaron Rosenblatt, Robert Shay, Barzin Keramati, Peter Kazlas, Madhu Anand

Publication number: 20100209338Abstract: A hydrogen-generating material composition of the present invention contains at least one metallic material selected from the group consisting of aluminum, silicon, zinc, magnesium, and alloys mainly composed of at least one of those metal elements, and a water-soluble salt of hydroxy acid. In the hydrogen-generating material composition, the ratio of the water-soluble salt of hydroxy acid to the total of the metallic material and the water-soluble salt of hydroxy acid is 1 mass % or more. A method for producing hydrogen according to the present invention is provided, wherein hydrogen is generated by supplying water to the hydrogen-generating material composition of the present invention so that a reaction occurs between the metallic material and the water.Type: ApplicationFiled: September 3, 2008Publication date: August 19, 2010Inventors: Takeshi Miki, Toshihiro Nakai, Shoji Saibara
