MU Researchers Create Smaller and More Efficient Nuclear Battery

剛剛朋友MSN傳來核能電池的新聞
本來想說不大可能所以上網找了一下
還真找到了密蘇里大學的新聞稿
據說還是韓裔研究員Jae Wan Kwon開發出來的...

所以我暫且在這隨筆記下
看看這小子會不會變成第二個韓國民族英雄황우석!!

COLUMBIA, Mo. – 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 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,” said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope battery can provide power density that is six orders of magnitude higher than chemical batteries.”

Kwon and his research team have been working on building a small nuclear battery, currently the size and thickness of a penny, intended to power various micro/nanoelectromechanical systems (M/NEMS). Although nuclear batteries can pose 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 innovation is not only in the battery’s size, but also in its semiconductor. Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.

“The critical part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor,” Kwon said. “By using a liquid semiconductor, we believe we can minimize that problem.”

Kwon has been collaborating with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, and is working to build and test the battery at the facility. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair. They’ve also applied for a provisional patent.

Kwon’s research has been published in the Journal of Applied Physics Letters and Journal of Radioanalytical and Nuclear Chemistry. In addition, last June, he received an “outstanding paper” award for his research on nuclear batteries at the IEEE International Conference on Solid-State Sensors, Actuators and Microsystems in Denver (Transducers 2009).

台北帝国大学

看網路上人家講"台北帝國大學"我都以為是胡謅出來的
沒想到還真有這麼間學校
而且還解釋了某些人的奴性為什麼這麼重...

今天上說頻想看看異俠有沒有動靜
結果突然在討論版裡看到了 愛情，緣分減自卑乘以勇氣。
乍看之下blog內容似乎是鼓勵大家拿出面對自我....並且挑戰一切的勇氣
然....開板網友卻提出了更具建設性、革命性、破壞性兼具的見解

那就是....國小數學老師必教會大家的

原文刊載於【轉載】愛情，緣分減自卑乘以勇氣。
以下為原文節錄

－－－－－－－－－－－－－－－－－－－－－－－－－－

愛情 = 緣分 - 自卑 x 勇氣

四則運算基本法則，先乘除後加減……

愛情 = 緣分 - 自卑 x 勇氣
　　 = 緣分 - （自卑 x 勇氣）

假設一　自卑、勇氣為固定數，緣分為變動數
　　　　　　　　　　　　得【緣分與愛情成正比】

假設二　緣分、勇氣為固定數，自卑為變動數
　　　　　　　　　　　　得【自卑與愛情成反拋物線比】

假設三　緣分、自卑為固定數，勇氣為變動數
　　　　　　　　　　　　得【勇氣與愛情成反拋物線比】

從上述可得知要成就一份愛情，取決於極大的緣分 + 極小的自卑 + 極小的勇氣

因此，自卑、跟勇氣是愛情殺手，而緣分則是愛情的來源


我的運算應該沒錯吧　囧

沒錯....喵大....你真的沒算錯....
