我校校友杨培东等研发出世界上第一个液体纳米晶体管
据中新网7月4日报道,美国加州大学伯克利分校6月28日宣布,该校化学教授杨培东
及其合作伙伴Majumdar研发出世界上第一个液体纳米晶体管,这将成为未来生化处理器的
奠基性技术。
液体纳米晶体管技术的诞生,使得纳米导管不仅对电子,也可以对生化离子进行传
导。未来只要极其微量的血液,就可以对其中的蛋白质、抗体等进行结合,从而达到疾病
诊断的作用。
杨培东教授说,这项研究目前仍然处于基础阶段,但是一个重要的里程碑,可以预
见在未来的10年、20年中,随着该技术的成熟,液体纳米晶体管会被批量生产,他们也会
尽可能地促进技术的产业化。
杨培东教授1993年毕业于中国科技大学应用化学系,在哈佛大学获得化学博士学位
,1999年开始在加州大学伯克利分校担任教授,在纳米技术、激光器等方面有所建树。他
和机械教授Majumdar都是劳伦斯柏克莱国家实验室的科学家,从事这项技术的研究已经3年
多。
纳米技术是20世纪90年代出现的一门新兴技术。它是在0.10至100纳米(即

China’s Shoddy, Noisy Nuclear Submarines
Over the past two decades, the People’s Republic of China has made great
advances in its military capabilities. However, it still lags woefully
behind in developing nuclear-powered submarines. The problem for the Chinese
is that they lack the necessary quieting and propulsion technologies to
build anything remotely comparable to an American or Russian nuclear
submarine.

慈祥可亲的朋友
1950年4月1日,印度成为首个与新中国建交的非社会主义阵营的国家。
当年5月,印度驻华大使潘尼卡尔第一次见到了毛泽东。
在回忆录中,潘尼卡尔对毛泽东充满好感与敬意:
“(毛泽东)的面容慈祥可亲,目光诚恳……在他的言行举止中我看不到任何冷酷或残
忍。实际上,他更像是一位思想家,有些理想主义,但是绝对真诚。”

英国皇家宫廷剧院近期以“财政原因”为由取消上演一部有关西藏的戏剧。不过,最新
曝光的剧院与英国一政府部门间的通信显示,该剧被撤档的真实原因是忌惮中国。
场地定好了,海报印好了,印度知名剧作家阿比谢克•玛炯达(Abhishek
Majumdar)的戏剧作品《帕拉》(Pah-La)原定去年10月4日起开始在位于伦敦西区的
皇家宫廷剧院上映,为期一个月。
《帕拉》描述的是当代藏人的生活,灵感源自玛炯达在印度流亡藏人社区接触的藏人和
他们的个人故事。皇家宫廷剧院起初宣布推迟上演该剧,但随后在今年1月宣布取消演
出,理由是“财政原因”。
但是最新流出的通信记录显示,英国政府下属的文化外交分支——英国文化教育协会私
下劝诫剧院说,这台戏剧的上映日期与中国的“重大政治会议”时间重合,可能影响该
剧院今后在中国的活动。当时正值中国执政的共产党即将召开第十九次全国代表大会前
夕。
英国文化教育协会官员马昌(Nick Marchand)在看过《帕拉》的剧本草稿后复信皇家
宫廷剧院说:“我们能做的是让你们了解这件事的敏感性及可能产生的后果。”
他写道:“坦率地说,我们确实觉得《帕拉》可能损害皇家... 阅读全帖

黄卫东:美国军事进攻中国可能性分析与对策

一、美国对外发动战争的特点
美国自独立建国以来,除在北美大陆发动的对印第安人一百多次战争外,发动的对
外战争及军事行动,到2001年就达到130次[1],包括两次侵略中国的战争,一次是参加
八国联军侵华,一次是带领联合国军攻入朝鲜时轰炸中国东北,准备攻入中国,遭志愿
军击败(这里不计旧中国时代美军在中国境内开枪开炮,如1927年炮击南京伤亡2000多
人[2])。美国是近代以来发动对外战争最多的国家,仅奥巴马上任总统八年,虽获诺贝
尔和平奖,却在任上指挥美军入侵七国[3]。
美国发动的战争,绝大部分是针对小国和弱国,很多时候,还拉上一帮盟国帮助。
针对较强国家的战争,主要包括以下几次:
1、19世纪初,英法战争正酣,1812年6月18日美国趁机向英国宣战[4],发动了针
对英国在北美殖民地加拿大的战争。虽然美军一开始有所进展,但后来英国增兵,一度
占领美国首都华盛顿,纵火烧毁了白宫、国会大厦等政府建筑。最终双方停战,恢复战

Corps and US Special Operations Command.
"We are already finalising our designs for what that roll-on/roll-off kit

你这个实验具体是想得出什么结论呢? 如果要求不高我们一般都不校正. 你是做single

以前实验室做得bulk FRET的实验,就是简单的测Ratio A来校正,操作很简单.

Finish your ph.D with him, then go Majumdar group to do postdoc, then you

on your effort, talent, and luck.
