Time and nanotechnology

History of nanotechnology The concepts that seeded nanotechnology were first discussed in by renowned physicist Richard Feynman in his talk There's Plenty of Room at the Bottomin which he described the possibility of synthesis via direct manipulation of atoms.

The term "nano-technology" was first used by Norio Taniguchi inthough it was not widely known.

Time and nanotechnology

Eric Drexler used the term "nanotechnology" in his book Engines of Creation: The Coming Era of Nanotechnologywhich proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity with atomic control.

Also inDrexler co-founded The Foresight Institute with which he is no longer affiliated to help increase public awareness and understanding of nanotechnology concepts and implications.

Thus, emergence of nanotechnology as a field in Time and nanotechnology s occurred through convergence of Drexler's theoretical and public work, which developed and popularized a conceptual framework for nanotechnology, and high-visibility experimental advances that drew additional wide-scale attention to the prospects of atomic control of matter.

Since the popularity spike in the s, most of nanotechnology has involved investigation of several approaches to making mechanical devices out of a small number of atoms. First, the invention of the scanning tunneling microscope in which provided unprecedented visualization of individual atoms and bonds, and was successfully used to manipulate individual atoms in Buckminsterfullerene C60, also known as the buckyballis a representative member of the carbon structures known as fullerenes.

Members of the fullerene family are a major subject of research falling under the nanotechnology umbrella. In the early s, the field garnered increased scientific, political, and commercial attention that led to both controversy and progress.

Controversies emerged regarding the definitions and potential implications of nanotechnologies, exemplified by the Royal Society 's report on nanotechnology.

These products are limited to bulk applications of nanomaterials and do not involve atomic control of matter. Some examples include the Silver Nano platform for using silver nanoparticles as an antibacterial agent, nanoparticle -based transparent sunscreens, carbon fiber strengthening using silica nanoparticles, and carbon nanotubes for stain-resistant textiles.

By the mids new and serious scientific attention began to flourish. Projects emerged to produce nanotechnology roadmaps [19] [20] which center on atomically precise manipulation of matter and discuss existing and projected capabilities, goals, and applications.

Fundamental concepts Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products.

By comparison, typical carbon-carbon bond lengthsor the spacing between these atoms in a moleculeare in the range 0. By convention, nanotechnology is taken as the scale range 1 to nm following the definition used by the National Nanotechnology Initiative in the US.

The lower limit is set by the size of atoms hydrogen has the smallest atoms, which are approximately a quarter of a nm kinetic diameter since nanotechnology must build its devices from atoms and molecules.

The upper limit is more or less arbitrary but is around the size below which phenomena not observed in larger structures start to become apparent and can be made use of in the nano device.

In the "bottom-up" approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. The positions of the individual atoms composing the surface are visible. Nanomaterials Several phenomena become pronounced as the size of the system decreases.Nanotechnology Young Researcher Award Dr Stephan Wirths, currently working at IBM Zurich, is the winner of the Young Researcher Award.
