“There’s Plenty of Room at the Bottom” Richard P. Feynman December 1959 The classic talk that Richard Feynman gave on December 29th 1959 at the annual meeting of the American Physical Society at the California Institute of Technology (Caltech) • I would like to describe a field, in which little has been done, but in which an enormous amount can be done in principle. • Furthermore, a point that is most important is that it would have an enormous number of technical applications. • What I want to talk about is the problem of manipulating and controlling things on a small scale 4 4 4
Why can’t we write the entire 24 volumes of the Encyclopedia Britannica on the head of a pin? Let’s see what would be involved. The head of a pin is a sixteenth of an inch across. If you demagnify it by 25,000 diameters, the area of the head of the pin is then equal to the area of all the pages of the Encyclopedia Britannica. Therefore, all it is necessary to do is to reduce in size all the writing in the Encyclopedia by 25,000 times. Is that possible? The resolving power of the eye is about 0.2mm – that is roughly the diameter of one of the little dots on the fine half-tone reproductions in the Encyclopedia.This, when you de-magnify it by 25,000 times, is still 80 angstroms (8nm) in diameter – 32 atoms across, in an ordinary metal. 5 5 5
Nanotechnology? “Nanotechnology is defined as the study, the control and the use of materials and material structures between 1 nanometer (nm) and 100 nanometers and making devices out of these. 1nm is one billionth of a meter and the human hair/ paper sheet , is about 80,000 nm thick. *********** 6 6

Colin L. Powell Former Secretary of State United States Government Remarks to the 139th Annual Meeting of the National Academy of Sciences10 a.m. Tuesday, April 30, 2002 Washington, D.C. • “Indeed, new avenues of scientific research may produce technologies as revolutionary in their security, economic and social implications as information technology has been since the mid-1980s. One area of biotechnical research alone, nanotechnology, could have enormous implications -- some thrilling, others chilling -- on terrorism, defence, health, development and the world economy”.
TONY BLAIR'S SPEECH ON BRITISH SCIENCETHURSDAY MAY 23, 2002 “The current work in nanoscience - manipulating and building devices atom by atom - is startling in its potential. From this we now see emerging nanotechnology. Programmable and controllable microscale robots will allow doctors to execute curative and reconstructive procedures in the human body at the cellular and molecular level. Visionaries in this field talk about machines the size of a cell that might, for example, identify and destroy all the cancerous cells in a body. Nanomachines might target bacteria and other parasites, dealing with tuberculosis, malaria and antibiotic-resistant bacteria”.
President Clinton, 2000 The National Nanotechnology Initiative In his speech proposing the NNI, President Clinton(2000) invoked this vision on Feynman’s home ground: My budget supports a major new National Nanotechnology Initiative, worth $500 million. Caltech is no stranger to the idea of nanotechnology —the ability to manipulate matter at the atomic and molecular level. More than 40 years ago, Caltech’s own Richard Feynman asked, “What would happen if we could arrange the atoms one by one the way we want them? 14
Russian Budget For Nanotechnology The Russian government would allocate 200 billion rubles ($7.7 billion)to develop nanotechnology until 2015and transfer to the state corporation 130 billion rubles ($5 billion) by the end of this year. As of now, the government has invested about 150 billion rubles ($5.76 billion) in different nanotechnology studies including weapons projects. In 2007, 12 billion rubles ($461 million) has been appropriated for the development of nanotechnologies, an incredible sum by Russian standards i.e. more than 5 times allocated for this purpose in 2006. This year's nanotechnologies budget of Russia is comparable to USA, European Union and Japan. Source: http://en.rian.ru/russia/20070723/69482473.html, 23rd July, 2007 15 15 15

Nano Gears • Two Fullerene Nano-gearswith multiple teeth. It is hoped that products can be constructed made of thousands of tiny machines that could self-repair and adapt to their environment. • Researchers have simulated gear teethby attaching benzyne molecules to the outside of a nanotube. • To "drive" the gears, a supercomputer simulated a laser that served as a motor • Nanotubes are molecular-sized pipes made of carbon atoms
Carbon Nanotubes • Carbon nanotube(CNT) is a new form of carbon, equivalent to two dimensional graphene sheet rolled into a tube • Two main types of nanotubes are, • - Single-Walled Nanotubes(SWNTs) and • - Multi-Walled Nanotubes(MWNTs). • Tensile strength~ 200 Giga Pascal, ideal for reinforced composites and nano-electromechanical systems (NEMS) • Metallic or semiconducting and offers amazing possibilities to create future nanoelectronics devices, circuits, and computers • Nanotubes are based on carbon or other elements. These systems consist of graphitic layers seamlessly wrapped into cylinders.
Nanosensor • Requirement • Electronic noses: a chemical sensing system that contains an array of several different types of sensors, where each element measures a different property of the sensed chemical • Applications • Detecting hazardous emissions from chemical plants • Detection and control of automobile emissions • Odor control in chemical and food processing • Discrimination of breath alcohol constituents
Computer / Information Technology • Nanoelectronics: Biomolecules • IT: Large density information 1012 • Next generation computer chips • Large electro chromic devices • Nano-computers with molecular machines will allow almost anything to be designed and made from inexpensive raw materials, such as, air, sunlight or even dirt. • Specific magnetic properties for magnetic recording • High erosion resistance
Saving Energy through advanced Nanomaterials • Saving energy through the use of nano materials and the current $1.6 billion dollar market, predicted to rise to $5.1 billion by 2014. • Despite advances in battery technology, hydrogen storage and fuel cells, energy saving technologies will exhibit a faster growth. • Solid state lighting, nanocomposite materials, aerogels and fuel borne catalysts will have the greatest impact between now and 2014 • Applications in transportation will increase to $50 billion by 2014 .
The Nano Revolution in Materials • This new science of the small has brought to market self-cleaning windows, smog-eating concrete and toxin-sniffing nanosensors. • 300 nanoengineered products are now commercially available; $32 billion worth of them were sold last year, with sales expected to top $1-2 trillion by 2015. • Nanoscientists are creating revolutionary materials like single atom thick coatings, carbon nanotubes up to 50 times stronger than steel (yet 10 times lighter), and quantum dots that could enable us to change the color of almost any object instantaneously.
