hehe, 还是你说的比较直接, 我看了他们关于NANOTUBE的一系列文章, 觉得就是把
高华键以前的一个模型(VIB MODEL)用在NANOTUE上,其实没什么新东西, 不过他们是
名校教授,所以不敢亡加评价啊, 呵呵
纳米里面别的东西我不太清楚, 就NANOTUBE这块来说, 就这么一根管子,
7,8年前已经把它的拉/压/弯/扭模拟的很清楚了, 力学特性可以研究的已经比较狭窄,
更何况其实并不需要力学的多少高深知识....
我说的自于自乐主要是觉得主流的纳米科学家可能根本不关心/需要 ME的人来做什么,
而ME的人做的东西, 就我目前看到的文章来说, 很难说能有多大意义有多大应用.
更大的可能是过几年又有别的东西热了, 大家一拥而上又转到那里去, 在NANO里只留下
一大堆文章数..... (以前的MEMS是不是也这样啊?) |

"These emissions may logically be attributed to the trapping of excitation
energy by defect sites in the nanotube structure, which are passivated upon
