考题 DBatteries 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.71. Which of the following is true of Jae Kwon?A. He teaches chemistry at MU.B. He developed a chemical battery.C. He is working on a nuclear energy source.D. He made a breakthrough in computer engineering.

考题共用题干 Batteries Built by VirusesWhat do chicken pox,the common cold,the flu,and AIDS have in common?They're all diseases caused by viruses,tiny microorganisms that can pass from person to person. It's no wonder that when most people think about viruses,finding ways to steer clear of viruses is what's on people's minds.Not everyone runs from the tiny disease carriers,though. In Cambridge,Massachu- setts,scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work,teaching them to build some of the world's smallest rechargeable batteries.Viruses and batteries may seem like an unusual pair,but they're not so strange for engi-neer Angela Beicher,who first came up with the idea. At the Massachusetts Institute ofTechnology(MIT)in Cambridge,she and her collaborators bring together different areas of science in new ways.In the case of the virus-built batteries,the scientists combine what they know about biology,technology and production techniques.Beicher's team includes Paula Hammond,who helps put together the tiny batteries,andYet-Ming Chiang,an expert on how to store energy in the form of a battery.“We're working on things we traditionally don't associate with nature，”says Hammond.Many batteries are already pretty small. You can hold A,C and D batteries in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year,new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink,ordinary batteries won't be small enough to fit in-side.The ideal battery will store a lot of energy in a small package.
