New energy storage method may fight bioterror

Washington State University researchers have developed a way to store energy and provide defenses against potential biological attacks from terrorists.

Washington State University professor Choong-Suk Yoo, who recently published the results of the study in the online edition of Nature Chemistry, told that he was successful in using xenon diflouride as a way to store energy by turning gas into a solid.

Yoo also said that, in addition to creating this “battery,” he has also made what could eventually become a germ-fighting super-oxidizing compound.

“Flourine is the element which is the strongest oxidizer of all elements available,” Yoo told “It has been one of the dreams to making a metallic, or polymeric form of the fluorine itself.”

Once perfected, the fluorine could be used to defend against biological or chemical terrorist attacks, Yoo said.

Yoo also said that he is working on ways to try to solidify xenon diflouride using the least amount of energy and on how to keep it a solid.

Funding for the Washington State University research has been provided through the National Science Foundation and the Defense Department.

Xenon diflouride is one of the most stable xenon compounds. It is moisture sensitive and decomposes on contact with light or water vapor. In its solid form, xenon diflouride is a dense, white crystalline solid with a nauseating odor.
