A number of advantages of nanostmctured materials over bulk materials and their potential applications in many scientific and technological fields have been revealed in recent years. To find out the main growth and trends of this exciting new science and technology felds the growth rate of the nano-prefixed terms in the title of journal papers has been measured. It has been shown that the investigations dealing with graphite nanotubes represent kinetically the most active field of research in the nanosciences.Nanoscience and -technology deal with materials and structures having dimensions that mesure up to billionth of a meter (nanometer). A multitude of basic properties of materials are defined by length scales in the range of 10 to 200 Angstroms. When a solid is produced in a way that at least one of its dimensions is smaller than the length scale of some property, that property gets "confined" and will depend on the size and shape of what is called a "quantum crystal". At nanoscale one enters a world where physics and chemistry meet and novel properties of matter develop. 1,2 Based on these properties, a universe emerges, the characteristics of which can be applied to a full range of other disciplines including technologies that can, e.g., manipulate individual atoms with tiny probe elements.Visionaries 3 are seeing, in addition to the birth of a new nanoscience of materials with revolutionary electrical, optical, magnetic, etc., properties, the coming of age of technologies for making molecular engines and robots which like cells could populate nanofactories or could make copies of themselves.One way of monitor the emergence of new fields is to peruse the many papers and reviews published on the topic. A more simple and perhaps more enlightening approach
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
