Naked molecule exposed!!!

Did that attract your attention? Scientists at IBM using a very powerful microscope took a picture of a molecule. That might not seem like much but we are talking about a picture where you can 'see' things that are less than a nanometer. The molecule is pentacene which is important for organic transistors. Those are switches made of things that aren't like the current ones which are made from silicon. Pentacene is a hydrocarbon, so a bunch of carbon atoms arranged in rings. The microscope that they used is an atomic force microscope which doesn't have a lens but has a very sharp tip. On the tip these scientists put a molecule of carbon monoxide. The carbon monoxide as it was dragged across the pentacene interacted with it and the result is a picture of pentacene. Is this useful? For sure. Useful for making tiny transistors out of single molecules. (for more info go to

Energy sipping chips
We don't think about energy when it comes to computers. Yea it gets warm especially those laptops. But energy is a big concern for computer makers because where there is energy there is heat and heat is not good. In the last year nanotechnology has made it possible to create parts of computers that are about 45 nanometers. That means that about 2000 would fit across the width of a hair. Not only are they making these computer chips with smaller parts but they are consuming less energy? How much? If you figure how much progress has been made in computer chips and figure the same amount of progress in cars----your car would get 100,000 miles to the gallon. That is about four times around the world on a gallon of gas. (from Intel)
