What are "Atoms" and do they REALLY exist?
Atoms are real - and they can be manipulated one-by-one to make new "designer" molecules and materials.
Scientists at the IBM Almaden laboratory in California teamed up with artists to create images by moving individual atoms on flat metallic surfaces - much like pointallism, the painting technique in which small, distinct dots of pure color are applied in patterns to form an image.
For example, the image at left is of the Kanji characters for "atom" constructed with iron (Fe) atoms individually deposited on a copper (Cu) surface. The literal translation is something like "original child."

Making Movies at the Atomic Level !
You're about to see the movie that holds the Guinness World Records™ record for the World's Smallest Stop-Motion Film. The ability to move single atoms — the smallest particles of any element in the universe — is crucial to IBM's research in the field of atomic memory. But even nanophysicists need to have a little fun. In that spirit, IBM researchers used a scanning tunneling microscope to move thousands of carbon monoxide molecules (two atoms stacked on top of each other), all in pursuit of making a movie so small it can be seen only when you magnify it 100 million times. A movie made with atoms.

A Boy And His Atom was created by a team of IBM Almaden scientists using a scanning tunneling microscope, Carbon monoxide molecules were manipulated into place on a copper substrate with a copper needle at a distance of 1 nanometer. They remain in place, forming a bond with the substrate because of the extremely low temperature of 5 K (−268.15 °C, −450.67 °F) at which the device operates. The oxygen component of each molecule shows up as a dot when photographed by the scanning tunneling microscope, allowing the creation of images composed of many such dots.
The team created 242 still images with 65 carbon monoxide molecules. The images were combined to make a stop-motion film. Each frame measures 45 by 25 nanometers. It took four researchers two weeks of 18-hour days to produce the film. Reference: |
