Welcome to this Study Guide to nanotechnology, Nanotechnology is widely considered to constitute the basis of the next technological revolution.
following on from the rst Industrial Revolution which began around 1750 with the introduc. tion of the steam engine and steelmaking and which parallelled or perhaps caused upheavals. in land ownership and agriculture practice The Industrial Revolution constituted as profound. a change in society and civilization as the earlier Stone Bronze and Iron revolutions each of. which ushered in a distinctly new age in the history of human civilization A second Industrial. Revolution began around the end of the 19th century with the introduction of electricity on. an industrial scale and which paved the way for other innovations such as wireless commu. nication and most recently we have had the Information Revolution characterized by the. widespread introduction of computing devices and the internet. Insofar as the further development of very large scale integrated circuits used for information. processing depends on reducing the sizes of the individual circuit components down to the. nanoscale i e a few tens of nanometres the Information Revolution has now become the Nano. Revolution just as steam engines powered dynamos for the industrial generation of electricity. But nanotechnology brings its own distinctive challenges notably i handling matter at the. atomic scale which is what nanotechnology is all about a synonym is atomically precise. engineering means that qualitatively di erent behaviour needs to be taken into account and. ii in order for atomically precisely engineered objects to be useful for humans they need to. be somehow multiplied which introduces the problem of handling vast numbers of entities. One should not underestimate the multidisciplinary nature of nanotechnology This forces. researchers to adopt a manner of working more familiar to scientists in the 19th century than. in the 21st Many active elds in nanotechnology research demand an understanding of diverse. areas of science Sometimes this problem is solved by assembling teams of researchers but. members of the team still need to be able to e ectively communicate with one another An. inevitable consequence of this multidisciplinarity is that the range of material that needs to.

Fundamental discoveries will doubtless continue to be made in the realm of a very small and. given the closeness of discoveries to technology in this eld in many cases they will doubtless. be rapidly developed into useful products, References to the original literature are only given as footnotes to the main text when I. consider the original article to be seminal or that reading it will bring some additional illumi. nation At the end of each chapter I list some mostly relatively short authoritative review. articles and a few books that could be usefully read by anyone wishing to go into more detail. These lists do not include standard texts on topics such as the general properties of matter. electricity and magnetism optics quantum mechanics and so forth.

What is nanotechnology,1 1 De nitions, Let us brie y recall the bald de nition of nanotechnology the design characterization pro. duction and application of materials devices and systems by controlling shape and size of the. nanoscale 1 The nanoscale itself is at present consensually considered to cover the range from 1. to 100 nm 2 A slightly di erent nuance is given by the deliberate and controlled manipulation. precision placement measurement modelling and production of matter at the nanoscale in or. der to create materials devices and systems with fundamentally new properties and functions. my emphasis Another formulation oating around is the design synthesis characteriza. tion and application of materials devices and systems that have a functional organization in. at least one dimension on the nanometre scale my emphasis The US Foresight Institute. gives nanotechnology is a group of emerging technologies in which the structure of matter is. controlled at the nanometer scale to produce novel materials and devices that have useful and. unique properties my emphases The emphasis on control is particularly important it is. this that distinguishes nanotechnology from chemistry with which it is often compared in the. latter motion is essentially uncontrolled and random within the constraint that it takes place. on the potential energy surface of the atoms and molecules under consideration In order to. achieve the desired control a special nonrandom eutactic environment needs to be a available. How eutactic environments can be practically achieved is still being vigorously discussed 3. E Abad et al NanoDictionary Basel Collegium Basilea 2005. This scale and indeed the de nitions are currently the subject of discussions within the International. Standards Organization ISO aimed at establishing a universal terminology.

A very succinct de nition of nanotechnology is simply engineering with. atomic precision, However we should bear in mind the fundamentally new properties and novel and unique. aspects that some nanotechnologists insist upon wishing to exclude existing artefacts had. happen to be small, Another debated issue is whether one should refer to nanotechnology or nanotechnologies. The argument in favour of the latter is that nanotechnology encompasses many distinctly. di erent kinds of technology But there seems to be no reason not to use nanotechnology in. a collective sense since the di erent kinds are nevertheless all united by striving for control. at the atomic scale, Elaborating somewhat on the de nitions one can expand nanotechnology along at least three. imaginary axes, 1 The axis of tangible objects in order of increasing complexity materials devices and. systems Note that the boundaries between these three can be crossed by such things as. smart materials, 2 The axis starts with passive static objects such as nanoparticles whose new i e dif.
ferent from those of bulk objects having the same chemical composition properties arise. from their small size It continues with active devices e g able to transduce energy. or store information or change their state that is their dynamical properties are ex. plicitly considered Further along the axis are devices of ever more sophistication and. complexity able to carry out advanced information processing for example Finally. we come to manufacture nanomanufacturing usually abbreviated to nanofacture also. called atomically precise manufacturing APM i e processes and nanometrology which. of course comprises a very varied collection of instruments and procedures Sometimes. these are considered under the umbrella of productive nanosystems which implies a. complete paradigm of sustainable nanofacture, 3 The axis starts with direct nanotechnology materials structured at the nanoscale in. cluding nanoparticles devices with nanoscale components etc continues with indirect. nanotechnology which encompasses things like hugely powerful information processors. based on very large scale integrated chips with individual circuit components within the. nanoscale and ends with conceptual nanotechnology which means the scrutiny of engi. neering and other including biological processes at the nanoscale in order to understand. them better,Download free ebooks at bookboon com,Nanotechnology What is nanotechnology. Within the context of active devices it is often useful to classify them according to the media. on which they operate electrons photons or liquid materials for example Thus we have. molecular electronics and single electron devices made from scaled down bulk materials such. as silicon nanophotonics which is nowadays often used as an umbrella term to cover planar. optical waveguides and bre optics especially when some kind of information processing is. involved and nano uidics smaller versions of the already well established micromixers used to. accomplish chemical reactions This classi cation is however of only limited utility because. many devices involve more than one medium for example nanoelectromechanical devices are. being intensively researched as a way of achieving electronic switching optoelectronic control. is a popular way of achieving photonic switching and photochemistry in miniaturized reactors. But nanotechnology brings its own distinctive challenges notably i handling matter at the atomic scale which is what nanotechnology is all about a synonym is atomically precise engineering means thatqualitatively dierent behaviour needs to be taken into account and ii in order for atomically precisely engineered objects to be useful for humans they need to be somehow multiplied
