Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“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/nanoelectromechanreal 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(半導(dǎo)體). 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(晶體結(jié)構(gòu)) 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.

You must have a favorite line or pet phrase you repeat often in your conversations. Studies say that pet phrases can reflect our changing society and reveal information about a person’s personality. Here are some of the most popular pet phrases among young people.
腦殘---nuts
I love the word and use it whenever I think a person is stupid, or a behavior is crazy. I learned the term from one of my classmates. Once, we saw two high school girls wearing miniskirts on a very cold winter day and my classmate called the two girls “nuts”. I don’t think the word reflects my personality. I use it because it sounds cool.
Diao Yujie, 22, computer science major at Nanjing University.
汗---stunning
I use this word very often. Once, my classmates and I were discussing how amusing QQ is. One guy suddenly burst out, “I have MSN too”. This comment had no relation with the topic we were discussing. I used this word and everybody laughed. I think it is a fantastic word that can change awkwardness to amusement.
Mu Li, 20, journalism major at Beijing Normal University.
暈死---I’m giddy!
I use this word a lot---more often than my classmates. It has became a symbol of me, as my friends sometimes refer to me as the guy who often says the word. I am a person who wants to be different and this word gives me that feeling.
Chen Zhou, 21, Nanjing University.
雷---stunning
I only use this word with my friends. My parents don’t understand it. The word, which is only used among people of my age, is intimate. I think it stands for being young and energetic. And I want to be young forever, so I like the word.
Chen Jianjun, 23, senior at Nanjing University.
【小題1】If a man wearing suit and a tie is climbing a mountain, what can we say to him according to the passage?
A.nuts | B.I’m giddy. | C.汗---stunning | D.雷---stunning |
A.習(xí)慣用語(yǔ) | B.寵物語(yǔ)言 | C.口頭禪 | D.座右銘 |
