Video of the day: the smallest film of atoms

IBM atom

Researchers at IBM have shown a funny animated video featuring the smallest particle of a chemical element – atoms . Guinness World Records recognized the painting “A Boy and His atom” the smallest in the world of film.

To shoot 250 shots, the scientists needed to place on the site of several thousand atoms. The main characters of the film are a boy named Atom and single particle. The creators did not get an Oscar standing problem, rather, their goal was to make its reach beyond the scientific community, to cause people interested in science.

In IBM moved the atoms using extremely sharp tip of a scanning tunneling microscope, managed by regular computer. The needle is located at a distance of 1 nm (one billionth of a meter) from the copper surface can attract the atoms and molecules (with the help of an electric current). This allows you to distribute the particles in the right place. Moving atom emits a particular sound that determines its current position.

IBM microscope

Microscope weighing two tons operated at 268 degrees Celsius below zero atoms and increases to more than 100 million times. The possibility of high-precision control of temperature, pressure and vibration makes the IBM Research Lab one of the few places in the world where you can move atoms with such precision – says researcher Christopher Lutz of IBM Research, who participated in the creation of animation.

Previously, this technology researchers have been able to create a magnetic memory cell of 12 atoms to store one bit of information. For comparison, in modern drives one bit of data represents about one million atoms.

“As data volumes continue to grow, you need to reduce the size of the carriers down to the atomic level. The same methods we use to develop new computing architectures and finding alternative ways of storing data, “- says Andreas Heinrich, who heads the research group IBM Research.

Previously, IBM announced a solar collector, which has no equal .
