“To provide enough power, we need certain methods with high energy density(密度)”,said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.

5 . Rae Armantrout, who has been a poetry professor at the University of California San Diego (UCSD) for two decades, has won the 2010 Pulitzer Prize in the poetry category for her most recent book, Versed.
“I’m delighted and amazed at how much media recognition that the Pulitzer brings, as compared to even the National Book Critics Award, which I was also surprised and delighted to win,” said Armantrout.“For a long time, my writing has been just below the media radar, and to have this kind of attention, suddenly, with my 10th book, is really surprising.”
Armantrout, a native Californian, received her bachelor’s degree at UC Berkeley, where she studied with noted poet Denise Levertov, and her master’s in creative writing from San Francisco State University. She is a founding member of Language Poets, a group in American poetry that analyzes the way language is used and raises questions to make the reader think.
In March, she won the National Book Critics Circle Award for Versed.
“This book has gotten more attention,” Armantrout said, “but I don’t feel as if it’s better.” The first half of Versed focuses on the dark forces taking hold of the United States as it fought the war against Iraq. The second half looks at the dark forces casting a shadow over her own life after Armantrout was diagnosed with cancer in 2006.
Armantrout was shocked to learn she had won the Pulitzer but many of her colleagues were not. “Rae Armantrout is a unique voice in American poetry,” said Seth Lerer, head of Arts and Humanities at UCSD.
Versed, published by the Wesleyan University Press, did appear in a larger printing than her earlier works, which is about 2,700 copies. The new edition is scheduled to appear in May.

[2] So, when Ashley was sixteen, she launched her own website, called Goosehead. She had no idea how big a success it would be, but three years later, the site was the most successful teen site in the USA! It was getting 100,000 hits every day, and Ashley had about 30 employees.
[3] After a few years, the website closed down. Then Ashley, who lives in Los Angeles, was asked to write a book called The Goosehead Guide to Life.
