China to conduct Pacific naval exercises
(AFP) – 2 hours ago
BEIJING — China has said it will conduct "routine" naval exercises in the
Pacific Ocean, in the week after a major diplomatic campaign by US President
Barack Obama to assert the United States as a Pacific power.
The defence ministry said the exercises were pre-arranged and did not target
any particular country, but the announcement comes against a background of

发帖数: 313 | 4 Tinkham group in Harvard recently explored the conductability of DNA
chains. They use lamda-DNA(which is random coded) as sample to test
the conductivity. Conclusion they draw is that DNA is basically insulate.
I will list the papers she mentioned in her talk to show the debate on
this issue in later post.
Some conclusions they got,
1. if DNA chain is shorter, it may be conductive(less than 400nm)
2. CG pair tends to be more conductive

发帖数: 2019 | 5 什么叫电导率(conductivity)？就是指某种特定材料的导电能力。如何才能简单快速
地测出这种导电能力呢？很自然，我们可以在材料的两端施加一个固定电压降，同
时测量流经该材料的电流。对于相同形状尺寸的不同材料，在外加电压降一样时，
电流越大的材料导电能力自然就越强。因此我们可以由此定义：
电导(conductance)=电流(current)/电压降(potential)
电流的标准单位是安培(Ampere)，电压的标准单位是伏特(Volt)。电导的标准单位
就是Ampere/Volt，为了使用方便，国际上将电导的标准单位称为“Siemens”，翻
译过来就叫“西门子”。一西门子等于一安培除以一伏特。但这仅仅是电导(conductance)
的单位，电导率(conductivity)的单位又是什么呢？可以想象，如果你的材料在与
电流流过的方向垂直的截面积越大，那么在相同电压降下你所得到的电流也就越大；
同时如果材料在电流流过的方向上的长度越长，那么在相同电压降下你所得到的电
流就越小(可以把电流想象成在导管中流动的液体)。因此电导和截面积成正比，和
长度成反比。如果我们把材料的长 |

发帖数: 238 | 13 That's a good direction, but it does not belong to traditional polymer
science, therefore is not being mentioned much here.
Conducting polymer is better classified as EE or physics here, like A.J.
Heeger is doing. You better know some condensed matter theory, like band
theory.
I think conducting polymer is still treated as a 1D object, therefore the
polymer character is not important, at least to the eyes of the main players
in the field. |

还有一个问题， 既然不知道expression number， 光知道I-V relationship， 在1992

They are physicists so they basically can only buy commercial available
DNAs. This is why they use lamda-DNA but not DNAs only have CG pairs.
It would be interesting if biologists who are capable of making specified
DNAs repeat their experiments. Their way of testing the conductability is
very cool. |

See my previous post. :-)
There is no definite conclusion whether DNA is conductive or insulative.
Different research groups in the world give all kinds of results. Well, some
of them even say that DNA is superconductive under Tc of 3K. The debate will
go on, you know, until a final conclusion is drawn. |

I think hole mobility in polymer should be related to its conductivity. Why it

cm2/Vs for field effect hole mobility, reponsding to 10 cm2/Vs for defect free
hole mobility.
I am quite confused at all those concepts such as hole drift velocity,
field-effect hole mobility and defect free hole mobility.
