| Atom-by-atom extraction |
| Source: Ohio University/Hla Group |
 | Individual silver atoms are pulled out from a nanosized silver cluster on a Ag(111) surface at 6 K using a scanning tunneling microscope tip. Just by approaching the tip close to a protruding part of the cluster, the binding energy of the topmost cluster atom is greatly reduced. When the STM-tip laterally moves, the atom breaks the bond with the neighboring atoms within the cluster, and follows the tip trajectory. This process involves manipulation of atom along rough terrains of the 3-D cluster surface. |

| Feasibility of molecular manufacturing |

 | A debate about the feasibility of Molecular Manufacturing. Can molecular assemblers be developed to create new materials, new devices, and even macroscopic objects? This animation is part of a museum exhibit developed for the Children's Museums. |

| Gear and shaft operation |

 | An example of a carbon nanotube gear and shaft operation with a powered gear. The gearshaft is a carbon nanaotube which may be just 1 to 10 nanometers in diameter. Benzyne molecules (as teeth) are attached to carbon nanotubes (shafts) to form gears that can operate at GHz frequencies. |

| Gear rotation |

 | An example of carbon nanotube gear rotation. The gearshaft is a carbon nanaotube which may be just 1 to 10 nanometers in diameter. Benzyne molecules (as teeth) are attached to carbon nanotubes (shafts) to form gears that can operate at GHz frequencies. This clip shows rotation speeds of 50/70/100 rot/ns in a vacuum. |

| IBM self assembly technology creates airgap microprocessors |
| Source: YouTube |
 | IBM is applying a breakthrough self-assembling nanotechnology to conventional chip manufacturing, borrowing a process from nature to build the next generation computer chips. The natural pattern-creating process that forms seashells, snowflakes, and enamel on teeth has been harnessed by IBM to form trillions of holes that are used to create insulating vacuums around the miles of nano-scale wires packed next to each other inside computer chips. |

| Nanomanufacturing: top-down and bottom-up |
| Source: Purdue University (via nanoHub) |
 | An overview of nanomanufacturing techniques, explaining the difference between top-down and bottom-up approaches. This animation is part of a museum exhibit developed for the Children's Museums. |

| Rotary assembler |
| Source: E-Spaces |
 | An animation of one possible version of a nanomanipulator array assembler system: The upper platter holds bulk-deposited molecules or moieties. An array of massively-parallel simple manipulators removes the molecules from the upper platter and adds them to devices being assembled on the lower platter. Different areas of the feedstock platter might have different kinds of molecules, such that several assembly steps can be carried out before having to change out the upper platter. The conical roller moves radially, while the upper platter moves up and down, to access these different areas. The STM tips would have some ability to compensate for the slippage of the roller as the tip reaches for its target. |

| Self-assembly: Nature's way to do it |
| Source: Vega Science Trust |
 | Kuniaki Nagayama recorded in 1997. Biology operates at two levels: the large scale which we can see and the underlying microscopic one. The amazing way in which intermolecular forces cause protein arrays to self-assemble, enabling Nature to fabricate the large scale components of living systems is described. |

| What is nanomanufacturing technology? |
| Source: Applied Materials |
 | With each new generation of semiconductor device, the critical dimension of electronic structures shrink, requiring new manufacturing systems and new capabilities, such as the ability to apply thin-films atom-by-atom. The solution lies in nanomanufacturing technology, the combination of an innovative use of materials with the practical concept of high-volume precision manufacturing. This production is a high-level review of nanotechnology. |
