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.

How to improve our life? Many people think that they have to accept whatever life throws at them. They'll say, "This is my destiny(命运).I cannot change it."
Of course not! You don't have to suffer needlessly. Your life depends on you, not on any other external(外部的)factor.
I know a woman who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is? She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, and then goes to sleep. Next day, the same routine cycle follows.
Huh! Is this what she calls "doing her best"? She believes she has tried her best and just accepts it in her heart that this is the life that has been intended for her and that her luck can only change if God wills it. She hasn't realized that we have to do our share of making the effort to live the life of our dreams.
Remember that you harvest what you sow. You have to get off the sofa, get your eyes off the TV screen, get your hands off the phone(unless it contributes to your success),and get your mind and body to work! Don't expect your luck to change, unless you do something about it. If something goes wrong, don't just regard it as a temporary setback; instead, learn your lesson, make the most of the situation, and do something to solve the problem. It's not enough to think positively; you also have to act positively.
If someone's life is in trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, don't just stand(or sit)there, do something to improve your life.
