Billionth

Abstract: This chapter presents an overview of nanomaterials and nanotechnologies Nanotechnology is used as a prefix for any unit such as a second or a meter, and it means a billionth of that unit Hence, a nanometer (nm) is a billionth of a meter, or 10 −9 meters To get a perspective of the scale of a nanometer, observe the sequence of images Despite the wide use of the word nanotechnology, the term has been misleading in many instances This is because some of the technology deals with systems on the micrometer range and not on the nanometer range (1–100 nm) Furthermore, the research frequently involves basic and applied science of nanostructures and not basic or applied technology Nanomaterials are also not undiscovered materials, but nanoscale forms of well-known materials such as gold, silver, platinum, iron, and others Finally, it is important to keep in mind that some past technology such as, for example, nanoparticles of carbon used to reinforce tires as well as nature's photosynthesis would currently be considered a form of nanotechnology

Abstract: "Nano" denotes a billionth; a nanometer is a billionth of a meter. New instrumentation and techniques have for the first time made possible materials research and engineering at this level, the scale of individual molecules and atoms. Extraordinary visions of material abundance, unprecedented materials, and powerful engineering capabilities have marked the arrival of nanotechnology, as well as dystopian scenarios of self-replicating devices running amok and causing global catastrophe. Largely a future possibility rather than present actuality, nanotechnology has become a potent cultural signifier. NanoCulture explores the ways in which nanotechnology interacts with, and itself becomes, a cultural construction. Topics include the co-construction of nanoscience and science fiction; the influence of risk assessment and nanotechnology on the shapes of narratives; intersections between nanoscience as a writing practice and experimental literature at the limits of fabrication; the Alice-in-Wonderland metaphor for nanotechnology; and the effects of mediation on nanotechnology and electronic literature. NanoCulture is produced in collaboration with the nano art exhibit at the Los Angeles C

Abstract: In this chapter we present an introduction to the principles and advances made in the fields of nanoscience and nanotechnology including inventions, discoveries, and design and study of molecular building blocks (MBBs) studied through nanoscience and applied in nanotechnology. Nanoscience is the study of systems in nanoscale and nanotechnology is the ability to systematically organize and manipulate properties and behavior of matter in the atomic and molecular levels. Through nanoscience and nanotechnology it has become possible to study and create very useful functional devices, materials, and systems on the 1–100 nm (one billionth of a meter) length scale.

Abstract: The word nano takes its meaning from the Greek word "nanos" which means dwarf. Nanoparticles are materials ranging in size between 1 and 100 nanometers. A nanometer is one billionth of a meter. Nanotechnology is an interdisciplinary field that researches the physical, chemical and biological structures of materials with dimensions of one billionth and deals with their usage areas. Nanomaterials are the cornerstones of nanotechnology and they possess unique optical, magnetic and electrical properties in this dimension. What makes nanotechnology so interesting is that materials behave differently from the macro world in this dimension. Power / weight ratio, conductivity, optical and magnetic properties change significantly as we move from macro dimension to nanosize. In this study, after giving general information about nanomaterials, nanotechnology processes, imaging techniques of nanomaterials, carbon nanotubes, nanocomposites, nanotechnology in nature and various nanotechnology applications have been investigated.
