Nanotubes



From Scientific American:

NANOTUBE YOGA MAT? The darlings of materials science, carbon nanotubes are superstrong and highly electrically conductive. But they are also finer and far shorter than the hair on a baby's head, which makes it hard to incorporate their full range of properties into everyday materials. Now a U.S. company has made sheets of the sooty stuff big enough to cover a grown-up. Nanocomp Technologies, Inc., based in Concord, N.H., wove its millimeter-length nanotubes into slim bundles and deposited them onto a rotating drum, yielding sheets up to three feet (one meter) wide and six feet long (such as the one shown here). The company says its paperlike nanotube sheets are as tough as stainless steel, 30 times less dense and might be useful in shielding electronics from interference or making ultrastrong composite materials.

Leadership

Check out the parody of Memoirs of a Geisha by Bobby Lee. Hilarious. Here's stuff on America's best leaders . Speaking of leadership, what makes a great leader? Do you have to be the smartest on the team? Or the best coordinator? It must really depend on the organization and job, but in general all leaders have to share similar traits. For example, I saw a brilliant basketball game today, Duke vs. Wake Forest. It's clear that Duke's leader is JJ Redick. That's because he is the most effective scorer, but also I think his will to win leads the team to achieve. Of course he is putting in perhaps the most work by scoring and playing nearly the whole 40 minutes. But he is defintely not the best defender on the team. So a leader needs to certainly be very skilled, but not necessarily the best at everything. The vision and determination is what makes a leader. Not everyone is a natural born leader. Some are better than others, by talent and nature. But I think leadership...

Yes, Taiwan Can!

I saw this image somewhere, and I thought it was nice. I hope we can spread it around! I apologize for not giving full credit, but if it's yours, let me know!

This weekend sucks!

So the Yankees are facing an uphill battle against the Angels. Hope they pull out of this one. The game today was pretty intense. Down 5-0 then went up 6-5 only to be beaten 11-7. Ugh! I don't know, they just lacked the stamina to pull things through today. Then again, I don't fault them. NY has a pretty tense weekend with the bomb alert, and I pray that all will be well. After all, in my heart NYC is still my home. This weekend is Fall Break. Unfortunately for me, the weather is bad so I probably can't go hiking, and then my boss told me Thursday that we have work to do over the weekend. Right now I am busy testing the microwave/rf generators for our quantum dot gate pulsing. We need to make sure that we can maintain the pulse form sent down to the sample with minimal distortion, reflection, attenuation and loss. This is made particularly difficult due to the size of our metal gates (which I made), on the order of 100 nm or less in width and less than 20 nm in thickness. S...
