. Nanotechnology (' nanotech') is manipulation of matter on an, and scale. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as. A more generalized description of nanotechnology was subsequently established by the, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100. This definition reflects the fact that effects are important at this scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to see the plural form 'nanotechnologies' as well as 'nanoscale technologies' to refer to the broad range of research and applications whose common trait is size.

Because of the variety of potential applications (including industrial and military), governments have invested billions of dollars in nanotechnology research. Through 2012, the USA has invested $3.7 billion using its, the European Union has invested $1.2 billion, and Japan has invested $750 million.

Nanotechnology as defined by size is naturally very broad, including fields of science as diverse as, etc. The associated research and applications are equally diverse, ranging from extensions of conventional to completely new approaches based upon, from developing with dimensions on the nanoscale to. Scientists currently debate the future. Nanotechnology may be able to create many new materials and devices with a vast range of, such as in, energy production, and consumer products. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various. These concerns have led to a debate among advocacy groups and governments on whether special is warranted.

Comparison of Nanomaterials Sizes Inspired by Feynman's concepts, used the term 'nanotechnology' in his 1986 book, which 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 in 1986, Drexler co-founded (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 the 1980s 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. In the 1980s, two major breakthroughs sparked the growth of nanotechnology in modern era. First, the invention of the in 1981 which provided unprecedented visualization of individual atoms and bonds, and was successfully used to manipulate individual atoms in 1989. The microscope's developers and at received a in 1986. Binnig, and Gerber also invented the analogous that year.

Buckminsterfullerene C 60, also known as the, is a representative member of the known as. Members of the fullerene family are a major subject of research falling under the nanotechnology umbrella.

Second, were discovered in 1985 by, and, who together won the 1996. C 60 was not initially described as nanotechnology; the term was used regarding subsequent work with related tubes (called and sometimes called Bucky tubes) which suggested potential applications for nanoscale electronics and devices. In the early 2000s, 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 's report on nanotechnology.

Challenges were raised regarding the feasibility of applications envisioned by advocates of molecular nanotechnology, which culminated in a public debate between Drexler and Smalley in 2001 and 2003. Meanwhile, commercialization of products based on advancements in nanoscale technologies began emerging. These products are limited to bulk applications of and do not involve atomic control of matter. Some examples include the platform for using as an antibacterial agent, -based transparent sunscreens, strengthening using silica nanoparticles, and carbon nanotubes for stain-resistant textiles. Governments moved to promote and into nanotechnology, such as in the U.S. With the, which formalized a size-based definition of nanotechnology and established funding for research on the nanoscale, and in Europe via the European. By the mid-2000s new and serious scientific attention began to flourish.

Projects emerged to produce nanotechnology roadmaps 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. One (nm) is one billionth, or 10 −9, of a meter.

By comparison, typical carbon-carbon, or the spacing between these in a, are in the range 0.12–0.15 nm, and a double-helix has a diameter around 2 nm. On the other hand, the smallest life-forms, the bacteria of the genus, are around 200 nm in length. By convention, nanotechnology is taken as the scale range 1 to 100 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 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.

These new phenomena make nanotechnology distinct from devices which are merely miniaturised versions of an equivalent device; such devices are on a larger scale and come under the description of. To put that scale in another context, the comparative size of a nanometer to a meter is the same as that of a marble to the size of the earth. Or another way of putting it: a nanometer is the amount an average man's beard grows in the time it takes him to raise the razor to his face. Two main approaches are used in nanotechnology. In the 'bottom-up' approach, materials and devices are built from molecular components which chemically by principles of. In the 'top-down' approach, nano-objects are constructed from larger entities without atomic-level control. Areas of physics such as, and have evolved during the last few decades to provide a basic scientific foundation of nanotechnology.

Larger to smaller: a materials perspective. Main article: Several phenomena become pronounced as the size of the system decreases. These include effects, as well as effects, for example the ' size effect' where the electronic properties of solids are altered with great reductions in particle size.

This effect does not come into play by going from macro to micro dimensions. However, quantum effects can become significant when the nanometer size range is reached, typically at distances of 100 nanometers or less, the so-called. Additionally, a number of physical (mechanical, electrical, optical, etc.) properties change when compared to macroscopic systems. One example is the increase in surface area to volume ratio altering mechanical, thermal and catalytic properties of materials. Diffusion and reactions at nanoscale, nanostructures materials and nanodevices with fast ion transport are generally referred to nanoionics. Mechanical properties of nanosystems are of interest in the nanomechanics research. The catalytic activity of nanomaterials also opens potential risks in their interaction with.

Materials reduced to the nanoscale can show different properties compared to what they exhibit on a macroscale, enabling unique applications. For instance, opaque substances can become transparent (copper); stable materials can turn combustible (aluminium); insoluble materials may become soluble (gold). A material such as gold, which is chemically inert at normal scales, can serve as a potent chemical at nanoscales. Much of the fascination with nanotechnology stems from these quantum and surface phenomena that matter exhibits at the nanoscale. Simple to complex: a molecular perspective. Main article: Modern has reached the point where it is possible to prepare small molecules to almost any structure.

These methods are used today to manufacture a wide variety of useful chemicals such as or commercial. This ability raises the question of extending this kind of control to the next-larger level, seeking methods to assemble these single molecules into consisting of many molecules arranged in a well defined manner. These approaches utilize the concepts of molecular self-assembly and/or to automatically arrange themselves into some useful conformation through a approach. The concept of molecular recognition is especially important: molecules can be designed so that a specific configuration or arrangement is favored due to. The Watson–Crick rules are a direct result of this, as is the specificity of an being targeted to a single, or the specific itself. Thus, two or more components can be designed to be complementary and mutually attractive so that they make a more complex and useful whole. Such bottom-up approaches should be capable of producing devices in parallel and be much cheaper than top-down methods, but could potentially be overwhelmed as the size and complexity of the desired assembly increases.

Most useful structures require complex and thermodynamically unlikely arrangements of atoms. Nevertheless, there are many examples of self-assembly based on molecular recognition in, most notably Watson–Crick basepairing and enzyme-substrate interactions. The challenge for nanotechnology is whether these principles can be used to engineer new constructs in addition to natural ones.

Molecular nanotechnology: a long-term view. Main article: Molecular nanotechnology, sometimes called molecular manufacturing, describes engineered nanosystems (nanoscale machines) operating on the molecular scale. Molecular nanotechnology is especially associated with the, a machine that can produce a desired structure or device atom-by-atom using the principles of.

Manufacturing in the context of is not related to, and should be clearly distinguished from, the conventional technologies used to manufacture nanomaterials such as carbon nanotubes and nanoparticles. When the term 'nanotechnology' was independently coined and popularized by (who at the time was unaware of an by Norio Taniguchi) it referred to a future manufacturing technology based on systems. The premise was that molecular scale biological analogies of traditional machine components demonstrated molecular machines were possible: by the countless examples found in biology, it is known that sophisticated, optimised can be produced. It is hoped that developments in nanotechnology will make possible their construction by some other means, perhaps using principles. However, Drexler and other researchers have proposed that advanced nanotechnology, although perhaps initially implemented by biomimetic means, ultimately could be based on mechanical engineering principles, namely, a manufacturing technology based on the mechanical functionality of these components (such as gears, bearings, motors, and structural members) that would enable programmable, positional assembly to atomic specification. The physics and engineering performance of exemplar designs were analyzed in Drexler's book Nanosystems.

In general it is very difficult to assemble devices on the atomic scale, as one has to position atoms on other atoms of comparable size and stickiness. Another view, put forth by Carlo Montemagno, is that future nanosystems will be hybrids of silicon technology and biological molecular machines. Richard Smalley argued that mechanosynthesis are impossible due to the difficulties in mechanically manipulating individual molecules.

This led to an exchange of letters in the publication in 2003. Though biology clearly demonstrates that molecular machine systems are possible, non-biological molecular machines are today only in their infancy. Leaders in research on non-biological molecular machines are Dr. And his colleagues at Lawrence Berkeley Laboratories and UC Berkeley. They have constructed at least three distinct molecular devices whose motion is controlled from the desktop with changing voltage: a nanotube, a molecular actuator, and a nanoelectromechanical relaxation oscillator. See for more examples.

An experiment indicating that positional molecular assembly is possible was performed by Ho and Lee at in 1999. They used a scanning tunneling microscope to move an individual carbon monoxide molecule (CO) to an individual iron atom (Fe) sitting on a flat silver crystal, and chemically bound the CO to the Fe by applying a voltage. Current research. This device transfers energy from nano-thin layers of to above them, causing the nanocrystals to emit visible light.

Nanomaterials The nanomaterials field includes subfields which develop or study materials having unique properties arising from their nanoscale dimensions. has given rise to many materials which may be useful in nanotechnology, such as carbon nanotubes and other fullerenes, and various nanoparticles and. Nanomaterials with fast ion transport are related also to nanoionics and nanoelectronics. Nanoscale materials can also be used for bulk applications; most present commercial applications of nanotechnology are of this flavor. Progress has been made in using these materials for medical applications; see. Nanoscale materials such as are sometimes used in which combats the cost of traditional solar cells.

Development of applications incorporating semiconductor to be used in the next generation of products, such as display technology, lighting, solar cells and biological imaging; see. Recent application of include a range of applications, such as, and. Bottom-up approaches These seek to arrange smaller components into more complex assemblies.

DNA nanotechnology utilizes the specificity of Watson–Crick basepairing to construct well-defined structures out of DNA and other. Approaches from the field of 'classical' chemical synthesis (Inorganic and ) also aim at designing molecules with well-defined shape (e.g. More generally, molecular self-assembly seeks to use concepts of supramolecular chemistry, and molecular recognition in particular, to cause single-molecule components to automatically arrange themselves into some useful conformation.

tips can be used as a nanoscale 'write head' to deposit a chemical upon a surface in a desired pattern in a process called. This technique fits into the larger subfield of. allows for bottom up assemblies of materials, most notably semiconductor materials commonly used in chip and computing applications, stacks, gating, and. Top-down approaches These seek to create smaller devices by using larger ones to direct their assembly. Many technologies that descended from conventional for fabricating are now capable of creating features smaller than 100 nm, falling under the definition of nanotechnology.based hard drives already on the market fit this description, as do (ALD) techniques. And received the Nobel Prize in Physics in 2007 for their discovery of Giant magnetoresistance and contributions to the field of spintronics.

Solid-state techniques can also be used to create devices known as or NEMS, which are related to or MEMS. can directly remove material, or even deposit material when suitable precursor gasses are applied at the same time. For example, this technique is used routinely to create sub-100 nm sections of material for analysis in.

Atomic force microscope tips can be used as a nanoscale 'write head' to deposit a resist, which is then followed by an etching process to remove material in a top-down method. Functional approaches These seek to develop components of a desired functionality without regard to how they might be assembled. Magnetic assembly for the synthesis of anisotropic superparamagnetic materials such as recently presented. seeks to develop molecules with useful electronic properties.

These could then be used as single-molecule components in a nanoelectronic device. For an example see rotaxane. Synthetic chemical methods can also be used to create, such as in a so-called. Biomimetic approaches. or seeks to apply biological methods and systems found in nature, to the study and design of engineering systems and modern technology.

Is one example of the systems studied. is the use of for applications in nanotechnology, including use of viruses and lipid assemblies. Is a potential bulk-scale application. Speculative These subfields seek to what inventions nanotechnology might yield, or attempt to propose an agenda along which inquiry might progress. These often take a big-picture view of nanotechnology, with more emphasis on its societal implications than the details of how such inventions could actually be created. Molecular nanotechnology is a proposed approach which involves manipulating single molecules in finely controlled, deterministic ways. This is more theoretical than the other subfields, and many of its proposed techniques are beyond current capabilities.

centers on self-sufficient machines of some functionality operating at the nanoscale. There are hopes for applying nanorobots in medicine, but it may not be easy to do such a thing because of several drawbacks of such devices. Nevertheless, progress on innovative materials and methodologies has been demonstrated with some patents granted about new nanomanufacturing devices for future commercial applications, which also progressively helps in the development towards nanorobots with the use of embedded nanobioelectronics concepts. Productive nanosystems are 'systems of nanosystems' which will be complex nanosystems that produce atomically precise parts for other nanosystems, not necessarily using novel nanoscale-emergent properties, but well-understood fundamentals of manufacturing.

Because of the discrete (i.e. Atomic) nature of matter and the possibility of exponential growth, this stage is seen as the basis of another industrial revolution., one of the architects of the USA's National Nanotechnology Initiative, has proposed four states of nanotechnology that seem to parallel the technical progress of the Industrial Revolution, progressing from passive nanostructures to active nanodevices to complex and ultimately to productive nanosystems. seeks to design materials whose properties can be easily, reversibly and externally controlled though a fusion of and. Due to the popularity and media exposure of the term nanotechnology, the words and have been coined in analogy to it, although these are only used rarely and informally. Dimensionality in nanomaterials Nanomaterials can be classified in 0D, 1D, 2D and 3D. The dimensionality play a major role in determining the characteristic of nanomaterials including, and characteristics.

With the decrease in dimensionality, an increase in surface-to-volume ratio is observed. This indicate that smaller dimensional have higher surface area compared to 3D nanomaterials.

Recently, are extensively investigated for, and applications. Tools and techniques. Typical setup. A microfabricated with a sharp tip is deflected by features on a sample surface, much like in a but on a much smaller scale.

A beam reflects off the backside of the cantilever into a set of, allowing the deflection to be measured and assembled into an image of the surface. There are several important modern developments. The (AFM) and the (STM) are two early versions of scanning probes that launched nanotechnology.

There are other types of. Although conceptually similar to the scanning developed by in 1961 and the (SAM) developed by and coworkers in the 1970s, newer scanning probe microscopes have much higher resolution, since they are not limited by the wavelength of sound or light. The tip of a scanning probe can also be used to manipulate nanostructures (a process called positional assembly). Methodology may be a promising way to implement these nanomanipulations in automatic mode. However, this is still a slow process because of low scanning velocity of the microscope. Various techniques of nanolithography such as, dip pen nanolithography, or were also developed.

Lithography is a top-down fabrication technique where a bulk material is reduced in size to nanoscale pattern. Another group of nanotechnological techniques include those used for fabrication of and, those used in semiconductor fabrication such as deep ultraviolet lithography, electron beam lithography, focused ion beam machining, nanoimprint lithography, atomic layer deposition, and molecular vapor deposition, and further including molecular self-assembly techniques such as those employing di-block copolymers.

The precursors of these techniques preceded the nanotech era, and are extensions in the development of scientific advancements rather than techniques which were devised with the sole purpose of creating nanotechnology and which were results of nanotechnology research. The top-down approach anticipates nanodevices that must be built piece by piece in stages, much as manufactured items are made. Scanning probe microscopy is an important technique both for characterization and synthesis of nanomaterials. Atomic force microscopes and scanning tunneling microscopes can be used to look at surfaces and to move atoms around. By designing different tips for these microscopes, they can be used for carving out structures on surfaces and to help guide self-assembling structures. By using, for example, feature-oriented scanning approach, atoms or molecules can be moved around on a surface with scanning probe microscopy techniques. At present, it is expensive and time-consuming for mass production but very suitable for laboratory experimentation.

Molecular Electronics

In contrast, bottom-up techniques build or grow larger structures atom by atom or molecule by molecule. These techniques include chemical synthesis, and positional assembly. Is one tool suitable for characterisation of self assembled thin films. Another variation of the bottom-up approach is or MBE. Researchers at like John R. Cho, and Art C. Gossard developed and implemented MBE as a research tool in the late 1960s and 1970s.

Samples made by MBE were key to the discovery of the fractional quantum Hall effect for which the 1998 Nobel Prize in Physics was awarded. MBE allows scientists to lay down atomically precise layers of atoms and, in the process, build up complex structures. Important for research on semiconductors, MBE is also widely used to make samples and devices for the newly emerging field of.

However, new therapeutic products, based on responsive nanomaterials, such as the ultradeformable, stress-sensitive vesicles, are under development and already approved for human use in some countries. Main article: As of August 21, 2008, the estimates that over 800 manufacturer-identified nanotech products are publicly available, with new ones hitting the market at a pace of 3–4 per week. The project lists all of the products in a publicly accessible online database.

Most applications are limited to the use of 'first generation' passive nanomaterials which includes titanium dioxide in sunscreen, cosmetics, surface coatings, and some food products; Carbon allotropes used to produce; silver in food packaging, clothing, disinfectants and household appliances; zinc oxide in sunscreens and cosmetics, surface coatings, paints and outdoor furniture varnishes; and cerium oxide as a fuel catalyst. Further applications allow to last longer, to fly straighter, and even to become more durable and have a harder surface. And have been infused with nanotechnology so that they will last longer and keep people cool in the summer. Are being infused with silver nanoparticles to heal cuts faster. And may become cheaper, faster, and contain more memory thanks to nanotechnology. Also, to build structures for on chip computing with light, for example on chip optical quantum information processing, and picosecond transmission of information. Nanotechnology may have the ability to make existing medical applications cheaper and easier to use in places like the 's office and at home.

Cars are being manufactured with so they may need fewer and less to operate in the future. Scientists are now turning to nanotechnology in an attempt to develop diesel engines with cleaner exhaust fumes. Platinum is currently used as the diesel engine in these engines. The catalyst is what cleans the exhaust fume particles.

First a reduction catalyst is employed to take nitrogen atoms from NOx molecules in order to free oxygen. Next the oxidation catalyst oxidizes the hydrocarbons and carbon monoxide to form carbon dioxide and water. Platinum is used in both the reduction and the oxidation catalysts. Using platinum though, is inefficient in that it is expensive and unsustainable. Danish company InnovationsFonden invested DKK 15 million in a search for new catalyst substitutes using nanotechnology.

The goal of the project, launched in the autumn of 2014, is to maximize surface area and minimize the amount of material required. Objects tend to minimize their surface energy; two drops of water, for example, will join to form one drop and decrease surface area. If the catalyst's surface area that is exposed to the exhaust fumes is maximized, efficiency of the catalyst is maximized.

The team working on this project aims to create nanoparticles that will not merge. Every time the surface is optimized, material is saved. Thus, creating these nanoparticles will increase the effectiveness of the resulting diesel engine catalyst—in turn leading to cleaner exhaust fumes—and will decrease cost.

If successful, the team hopes to reduce platinum use by 25%. Nanotechnology also has a prominent role in the fast developing field of.

When designing scaffolds, researchers attempt to the mimic the nanoscale features of a 's microenvironment to direct its differentiation down a suitable lineage. For example, when creating scaffolds to support the growth of bone, researchers may mimic. Researchers have successfully used -based nanobots capable of carrying out logic functions to achieve targeted drug delivery in cockroaches. It is said that the computational power of these nanobots can be scaled up to that of a. Main article: An area of concern is the effect that industrial-scale manufacturing and use of nanomaterials would have on human health and the environment, as suggested by research. For these reasons, some groups advocate that nanotechnology be regulated by governments.

Others counter that overregulation would stifle scientific research and the development of beneficial innovations. Research agencies, such as the are actively conducting research on potential health effects stemming from exposures to nanoparticles. Some nanoparticle products may have. Researchers have discovered that silver nanoparticles used in socks to reduce foot odor are being released in the wash.

These particles are then flushed into the waste water stream and may destroy bacteria which are critical components of natural ecosystems, farms, and waste treatment processes. Public deliberations on in the US and UK carried out by the Center for Nanotechnology in Society found that participants were more positive about nanotechnologies for energy applications than for health applications, with health applications raising moral and ethical dilemmas such as cost and availability. Experts, including director of the Woodrow Wilson Center's Project on Emerging Nanotechnologies David Rejeski, have testified that successful commercialization depends on adequate oversight, risk research strategy, and public engagement. Is currently the only city in the United States to regulate nanotechnology; in 2008 considered enacting a similar law, but ultimately rejected it. Relevant for both research on and application of nanotechnologies, the of nanotechnology is contested. Without state, the availability of private insurance for potential damages is seen as necessary to ensure that burdens are not socialised implicitly. Health and environmental concerns.

Main articles: and Nanofibers are used in several areas and in different products, in everything from aircraft wings to tennis rackets. Inhaling airborne nanoparticles and nanofibers may lead to a number of, e.g. Researchers have found that when rats breathed in nanoparticles, the particles settled in the brain and lungs, which led to significant increases in biomarkers for inflammation and stress response and that nanoparticles induce skin aging through oxidative stress in hairless mice. A two-year study at UCLA's School of Public Health found lab mice consuming nano-titanium dioxide showed DNA and chromosome damage to a degree 'linked to all the big killers of man, namely cancer, heart disease, neurological disease and aging'.

A major study published more recently in suggests some forms of carbon nanotubes – a poster child for the 'nanotechnology revolution' – could be as harmful as if inhaled in sufficient quantities. Of the Institute of Occupational Medicine in Edinburgh, Scotland, who contributed to the article on said 'We know that some of them probably have the potential to cause mesothelioma. So those sorts of materials need to be handled very carefully.'

In the absence of specific regulation forthcoming from governments, Paull and Lyons (2008) have called for an exclusion of engineered nanoparticles in food. A newspaper article reports that workers in a paint factory developed serious lung disease and nanoparticles were found in their lungs. Main article: Calls for tighter regulation of nanotechnology have occurred alongside a growing debate related to the human health and safety risks of nanotechnology. There is significant debate about who is responsible for the regulation of nanotechnology. Some regulatory agencies currently cover some nanotechnology products and processes (to varying degrees) – by 'bolting on' nanotechnology to existing regulations – there are clear gaps in these regimes. Davies (2008) has proposed a regulatory road map describing steps to deal with these shortcomings.

Stakeholders concerned by the lack of a regulatory framework to assess and control risks associated with the release of nanoparticles and nanotubes have drawn parallels with ('mad cow' disease), genetically modified food, nuclear energy, reproductive technologies, biotechnology, and. Andrew Maynard, chief science advisor to the Woodrow Wilson Center's Project on Emerging Nanotechnologies, concludes that there is insufficient funding for human health and safety research, and as a result there is currently limited understanding of the human health and safety risks associated with nanotechnology.

As a result, some academics have called for stricter application of the, with delayed marketing approval, enhanced labelling and additional safety data development requirements in relation to certain forms of nanotechnology. The Royal Society report identified a risk of nanoparticles or nanotubes being released during disposal, destruction and recycling, and recommended that 'manufacturers of products that fall under extended producer responsibility regimes such as end-of-life regulations publish procedures outlining how these materials will be managed to minimize possible human and environmental exposure' (p. The Center for Nanotechnology in Society has found that people respond to nanotechnologies differently, depending on application – with participants in more positive about nanotechnologies for energy than health applications – suggesting that any public calls for nano regulations may differ by technology sector.

Nanocomposites are attractive to researchers both from practical and theoretical point of view because of combination of special properties. Many efforts have been made in the last two decades using novel nanotechnology and nanoscience knowledge in order to get nanomaterials with determined functionality. This book focuses on polymer nanocomposites and their possible divergent applications. There has been enormous interest in the commercialization of nanocomposites for a variety of applications, and a number of these applications can already be found in industry. This book comprehensively deals with the divergent applications of nanocomposites comprising of 23 chapters. The book 'Advances in Nanocomposite Technology' contains 16 chapters divided in three sections. Section one, 'Electronic Applications', deals with the preparation and characterization of nanocomposite materials for electronic applications and studies.

In section two, 'Material Nanocomposites', the advanced research of polymer nanocomposite material and polymer-clay, ceramic, silicate glass-based nanocomposite and the functionality of graphene nanocomposites is presented. The 'Human and Bioapplications' section is describing how nanostructures are synthesized and draw attention on wide variety of nanostructures available for biological research and treatment applications. We believe that this book offers broad examples of existing developments in nanocomposite technology research and an excellent introduction to nanoelectronics, nanomaterial applications and bionanocomposites.

The main objective of this book is to give in-depth understanding of the physical electronics and mechanical properties of carbon nanotubes. In other words, this book is intended to provide a profound knowledge of these electrical and mechanical characteristics allowing the reader to further appreciate the potential and applications of carbon nanotubes. Readers of this book should have a strong background on physical electronics and semiconductor device physics. Philanthropists and readers with strong background in quantum transport physics and semiconductors materials could definitely benefit from the results presented in the chapters of this book. Especially, those with research interests in the areas of nanoparticles and nanotechnology. This book has been outlined as follows: A review on the literature and increasing research interests in the field of carbon nanotubes. Fabrication techniques followed by an analysis on the physical properties of carbon nanotubes.

The device physics of implemented carbon nanotubes applications along with proposed models in an effort to describe their behavior in circuits and interconnects. And ultimately, the book pursues a significant amount of work in applications of carbon nanotubes in sensors, nanoparticles and nanostructures, and biotechnology. Carbon nanotubes are one of the most intriguing new materials with extraordinary properties being discovered in the last decade. The unique structure of carbon nanotubes provides nanotubes with extraordinary mechanical and electrical properties. The outstanding properties that these materials possess have opened new interesting researches areas in nanoscience and nanotechnology. Although nanotubes are very promising in a wide variety of fields, application of individual nanotubes for large scale production has been limited.

The main roadblocks, which hinder its use, are limited understanding of its synthesis and electrical properties which lead to difficulty in structure control, existence of impurities, and poor processability. This book makes an attempt to provide indepth study and analysis of various synthesis methods, processing techniques and characterization of carbon nanotubes that will lead to the increased applications of carbon nanotubes. Originally published in 1986, K. Eric Drexler's Engines of Creation laid the theoretical foundation for the modern field of nanotechnology and articulated the amazing possibilities and dangers associated with engineering at the molecular scale. Unique for both its style and substance, the book is today recognized as the seminal work in nanotechnology and has earned Drexler the title of 'Father of Nanotechnology.' Engines of Creation 2.0: The Coming Era of Nanotechnology?

Updated and Expanded, is an ebook-only version. In addition to an updated look and feel for the ebook, Engines of Creation 2.0 has been expanded to include the first known lecture on nanotechnology by physicist Richard Feynman, the landmark open letter debate between Dr.

Drexler and the late nanotech pioneer and Nobel laureate Dr. Richard Smalley, analysis of the debate by Ray Kurzweil, and a number of new additions by Dr. Drexler, including his advice to aspiring nanotechnologists. This book contains 16 chapters. In the first part, there are 8 chapters describing new materials and analytic methods.

These materials include chapters on gold nanoparticles and Sol-Gel metal oxides, nanocomposites with carbon nanotubes, methods of evaluation by depth sensing, and other methods. The second part contains 3 chapters featuring new materials with unique properties including optical non-linearities, new materials based on pulp fibers, and the properties of nano-filled polymers. The last part contains 5 chapters with applications of new materials for medical devices, anodes for lithium batteries, electroceramics, phase change materials and matrix active nanoparticles. Probably the leading team that is driving forward the work on nanogenerators for converting mechanical energy into electricity is Zhong Lin Wang's group at Georgia Tech. So far, we have covered their exciting work in at least half a dozen Nanowerk Spotlights about nanopiezotronics and nanogenerators. To provide a comprehensive and coherent review about the development of nanogeneratos, Wang, Distinguished Professor and Director, Center for Nanostructure Characterization, has organized this book mainly based on our published papers to provide a coherent coverage about the nanogenerators from fundamental materials, basic physics principles and theory, scientific approach, engineering-scale up and technological applications, so that readers can get a full picture about the development of this technology. The entire 139-page book is composed of 11 chapters with hundreds of figures.
