IBM reports major advance in nanotube-based transistors
from the Molectronics dept.
According to a press release (20 May 2002), IBM announced it has created "the highest performing nanotubes transistors to date and has proven that carbon nanotubes can outperform the leading silicon transistor prototypes available today". According to the release, the IBM researchers were able to achieve the highest transconductance (measure of the current carrying capability) of any carbon nanotube transistor to date. The company said, "With the announcement, IBM is taking carbon nanotubes . . . another step closer to becoming an option for replacing silicon transistors in future devices."
The announcement garnered widespread attention. Read more for additional details of the research and selected press coverage, as well as links to posts on earlier IBM nanotube-related research. Additional information on the IBM announcement on the web:

Previous IBM work, in which researchers at IBM created and demonstrated the world's first logic-performing computer circuit within a single-molecule device based on a carbon nanotube (a NOT gate), was reported here on Nanodot on 27 August 2001.

Cooee!
Is this site officially dead, or what? Front page updates once in a blue moon and nobody motivated enough to post. Somebody call a vet and have it put to sleep. I miss the rantfests.

Re:Cooee!
I would also appreciate regular updates, daily if possible. Two recent events should be discussed.
1) The Bell Labs investigation and its impact on the perception of nanotechnology research.
2) Stephen Wolfram's new book 'A New Kind of Science' is out and he weighs in on Drexlerian nanotechnology. I just received the book last night and if I understand it properly, he not only thinks it is possible but will be even easier than the general consenus among supporters.

Re:Cooee!
Perhaps less people are submitting stories?
Is there another similar nanotech news site elsewhere that gets more attention?
Oh, and the rants? At first they were amusing, but they got old fast. But yes, better rants than silence.

Re:Cooee!
I've noticed this too. Nanodot goes through periods of quiescence were nobody posts and nobody submits stories.
I've submitted many stories and I've posted some diliberately provocative posts a few weeks ago but I can't do it all by myself!
I think that the folks are Foresight, should assign a minder for Nanodot and that minder should start drumming up visitors to Nanodot. This means make deals with other nanotech oriented sites, like Small Times. Perhaps even start running opinion pieces on these other sites or running ads on them or something.
I think that part of the trouble is that nanotech is still not really on the public's radar yet. They can rant about cloning and they can rant about operating systems because those are facts of everyday life now. Nanotech is still mostly in the lab and as such most of the discussions are sort of like discussions about SETI, top heavy with theory and non-existant experimental evidence.
