International Journal of Advances in Scientific Research and Engineering (ijasre), 2019

Nanotechnology is a field where scientific knowledge and ideas emanating from the sub-atomic, atomic and molecular levels are applied in the manufacture of new and smart materials. Nanotechnology makes use of the novel properties exhibited by materials in the nanoscale. Nanocrystalline materials have microscopic grain sizes of up to 100 nm with remarkably distinct optical, electrical, chemical, mechanical properties different from those of bulk materials. Nanoparticles can be used to develop materials with unique properties since the number of atoms on the surface of a particle in the nanoscale is comparable to that inside the particle. Hence in order to meet the advanced technological demands in the areas such as electronics, catalysis, ceramics, magnetic data storage, structural components etc., it is important to make use of materials in the nanometer scale. Nanotechnology is a rapidly growing field of science which encompasses researchers and scientists from the areas of biology, chemistry, engineering, materials science and physics. This technology provides the basis for research and manufacture of materials in the 21st century. In addition, this interdisciplinary technology will provide a strong platform for the growth of pharmaceutical industry, medical diagnosis, materials industry and the overall economy of the country which will eventually enhance creation of job opportunities, food security, good health and affordable housing in line with the government's "big four" agenda. It promises improved efficiency in ICT equipment used in computing, data storage (chips) and communications (fibre optics). It can be used to develop renewable energy sources such as solar cells and panels. It can also be utilized to synthesize filters that can be used to get rid of pollutants; contaminants, harmful salts and viruses in water and sewerage systems and for the diagnosis and treatment of diseases including cancer and to restore damaged human organs or tissues using engineered tissue.

Nanotechnology is one of the most promising technologies of the twenty-first century. Nanotechnology is described as the design, development, and implementation of materials and technologies on the nanoscale with the smallest functional components (1 to 100 nm). Nanotechnology covers a wide range of issues, from standard device physics and chemistry extensions to entirely new techniques based on molecular self-assembly, from developing new Nano size materials to investigating whether we can directly alter matter at the atomic scale level. Nanotechnology can be used in a variety of fields, including medical, agriculture, and environmental protection. Many diseases for which there are presently no treatments may be treated in the future as a result of nanotechnology. The use of nanotechnology in medical therapy needs a careful examination of its risks and potential side effects. Even scientists who oppose the use of nanotechnology agree that advancement in the field should continue since it offers enormous benefits, but more testing is needed to ensure its safety in people. Nano medicine may play a key role in the treatment of human and plant disorders, as well as the enhancement of normal human and plant physiology and systems, in the future. Nanoscience and nanotechnology are the study and application of extremely small objects, with applications in chemistry, biology, physics, materials science, and engineering, among other fields. Nanotechnology is being used in a range of energyrelated applications, including increasing the efficiency and cost-effectiveness of solar panels, producing new types of batteries, boosting fuel production efficiency through better catalysis, and building better lighting systems. Nano science and nanotechnology applications in engineering connect academic research in Nano science and nanotechnology to industry and everyday life. As a result, a diverse range of nanomaterials, nano devices, and nano systems have been developed and deployed for human benefit in a number of technical applications. Nanoscience and Nanotechnology in Engineering is based on the authors' numerous lectures and courses given all over the world. Nanotechnology has also helped to design more efficient and long-lasting materials, such as self-cleaning and self-repairing concrete and windows. Coatings based on nanotechnology can help with fire protection, corrosion resistance, insulation, and a range of other applications. All scientists, academicians, researchers, and students working in the fields of chemistry, biology, physics, materials science, and engineering, among other fields, will find this book quite valuable.

Nanotechnology, 2004

With effect from August 2004 the journal Nanotechnology will discontinue the `Letters to the Editor' section. The increase in publication speed achieved for all articles now means that letters have no advantage. Fully electronic publication processes including electronic submission, refereeing and proofing, ensure that all papers are processed with minimum delay and are published as soon as they are ready. The journal will continue to publish high-quality original research papers, reviews and tutorials, as well as papers on the ethical and societal implications of nanotechnology at the discretion of the Editorial Board. All submitted papers will undergo a pre-selection procedure for suitability by the Editors of the journal. If a paper is accepted for consideration by the journal it will be sent to independent experts in the field for peer review. To speed up the publication process, we encourage authors to suggest five independent experts in their field as potential referees and supply their title, name, affiliation and e-mail address. The Editors of the journal may use these names at their discretion. Authors may also request that certain people are not to be used as referees. Papers of special interest will be given the utmost priority and on acceptance will be publicized further through worldwide press releases and reviews on the Institute of Physics website and on nanotechweb.org. As a service to authors and to the international physics community, and as part of our commitment to give authors' work as much visibility as possible, all papers are freely available online for 30 days from their electronic publication date. This means open access for citations to everyone in the world. We will also send an electronic offprint of your published paper to ten colleagues of your choice, giving your article an increased chance of being cited quickly. In the meantime, we are pleased to announce an increase in the Impact Factor of the journal in 2003 to 2.304, which means that Nanotechnology is now ranked as one of the top 10 journals in the world in the Applied Physics category.

ACS Symposium Series, 2016

Nanotechnology is a new approach that refers to understanding and mastering the properties of matter at the nano-scale: one nano-meter (one billionth of meter) is the length of a small molecule. At this level, matter exhibits different and often amazing properties and the borders between established scientific and technical disciplines fade. Hence the strong interdisciplinary character that is associated with nanotechnology.
