Self-strengthening polymer nanocomposite works best under pressure
No one keeps carbon nanotubes down -- especially not these guys. The always popular allotropes have been enlisted by researchers at Rice University to create a composite material that gets stronger under pressure. When combined with polydimethylsiloxane, a rubbery polymer, the tubes form a nanocomposite that exhibits self-strengthening properties also exhibited in bones. During testing, the team found the material increased in stiffness by 12 percent after 3.5 million compressions. Apparently, the crew is stumped on why it reacts this way, but is no less eager to see it working in the real world -- discussion is already underway to use the stuff as artificial cartilage. And here we thought aerogel was cool. Full PR after the break.
Dell Streak's Gorilla Glass screen: torture tested for your amusement (video)
So we've been hearing rumors about the Dell Streak being some kind of a rugged bad boy. Word is, the Gorilla Glass display on this 5-inch slate is good enough to withstand pretty much anything a human would care to throw its way. Them's fighting words where we come from, so we did the only thing a responsible tech blog can do -- we put them to the test. Should you be brave enough to follow us after the break, you'll come upon our best efforts to destroy our own Streak prototype, albeit with little success. Then again, the end result might be less important than the journey there, which is not to be missed.
