The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom…… it is interesting that it would be, in principle possible for a physicist to synthesize any chemical substance that the chemist writes down. Give the orders, and physicist synthesizes it. How? Put the atoms where the chemist says, and so you make the substance Richard Feynman Nobel Laureate Caltech, 1959 10 nm Atomic/Subatomic scale Meso-scale 1 nm 1 Å 100 nm 1 m Top down approach - Lithography Bottom-up approach - Chemical Synthesis A.N.

Historic Periods: (1 day in our calendar 30 real years) Neolithic 9000BCJan 1 Bronze 3200BCJul 5 Iron 1200BCSep 10 (steel) 1850Dec 27 Silicon 1950Dec 30 (semiconductors) (10 AM) Synthetic 1990Dec 31 (polymers, superconductors,...) (4 PM) Humans appear on Earth about 230 days ago and live in caves until early May ! (I fear that some people still live there now…) History of a humankind in a more blunt perspective… Nanotechnology: the last few minutes of December 31 st !
Some of the applications outlined there may be rather far fetched, but its okay… one never really knows… If you want to get more info about nanotechnology or even get inspiration about possible applications, check out this special issue of Scientific American
Before we start building these nanomachines or even start thinking about doing so, we have to learn about surfaces and surface patterns. Lets start then…
Knowledge base better comprehension of nature, life A new world of products ~ $1 trillion / year in 10-15 years Materials beyond what chemistry can do: $340B/y in 10 years for materials and processing Electronics in 10-15 years: $300B/y for semiconductor industry, times more for global integrated circuits Pharmaceuticals in 10-15 years: about half of production will depend on nanotechnology, affecting about $180 B/y Chemical plants in 10-15 years: nanostructured catalysts in petroleum and chemical processing, about $100B/y Aerospace: (about $70B/y in 10 years, estimation by industry group) Would require worldwide ~ 2 million nanotech workers Improved healthcare extend life-span, its quality, human physical capabilities (~ $31B in tools for healthcare in 10 years) Sustainability agriculture, water, energy (~$45B/y in 10 years), materials, environment; ex: lighting energy reduction ~ 10% or $100B/y M.C.

Areas that already see (or could do so shortly) of commercial applications of nanotechnology drug delivery catalysts (many applications) solar energy (photovoltaic or direct hydrogen production) coatings (extra hard or with novel properties) batteries implants that encourage cell growth display technologies and e-paper insulation (thermal and electrical) medical imaging technologies composites containing nanotubes (multi-walled) sensors (bio and chemical) nanoparticle composites bioanalysis tools textiles and filters bioseparation technologies higher capacity hard drives printable electronic circuits new forms of computer memory alloys (e.g. steel or those used in prosthetics) single photon generators and detectors; new solid-state lasers abrasives; glues; lubricants; paints; fuels and explosives optical and electro-optical components NANOTECH: The Tiny Revolution 2001-2002 CMP Cientifica
Do ChEM-ies fit into the NANO-world? Absolutely YES. Many new great opportunities exist for growth, development, and progress in traditional areas… + NANO! Traditional Chemical Engineering morphed into many new fields… And it pays off! Graduates with B.S in Chemical Engineering (universal engineers) are the highest paid engineers in the US (starting $63K in 2012) Wheel of fortune!
