Novel effects can occur in materials when structures are formed with sizes comparable to any one of many possible length scales, such as the de Broglie wavelength of electrons, or the optical wavelengths of high energy photons. In these cases quantum mechanical effects can dominate material properties. One example is quantum confinement where the electronic properties of solids are altered with great reductions in particle size. The optical properties of nanoparticles, e.g. fluorescence, also become a function of the particle diameter. This effect does not come into play by going from macrosocopic to micrometer dimensions, but becomes pronounced when the nanometer scale is reached.
Nanotechnology is the scientific ability to control and restructure the matter at the atomic and molecular levels within the nanoscale. It is a modern branch of materials science dealing with the understanding of the role of nanomaterials(NM) in real-world applications. It is the creation and/or manipulation of various materials at nanometer (nm) scale, analysing their structural characteristics & properties for novel applications, attracting, producing and exploiting the nanoparticles in different dimensions and increase the utilisation potential of nano structured materials (NSM)in various fields.

nanotechnology has entered the sphere of water treatment processes. Many different types of nanomaterial’s are being evaluated and also being used in water treatment process.
Desalination is a key market area. Vast majority of worlds water is salt water, and though technology has existed for years that enables the desalination of ocean water, it is often a very energy intensive procedure and therefore expensive
Nano porous membranes for water purification by shrinath ghadgeShrinath Ghadge
Continuous population growth and urbanization as well as rapid industrialization, causing huge contamination of potable water or underground water, has been a serious concern all over the world. Due to incompetency of conventional water purification technologies to deliver complete pollutants free water at an economical price, a high performance, cost-effective and environmentally acceptable separation system is an urgent need which should not only remove macro-, micro- and nano-pollutants but also desalinate water to a significant extent. In this milieu, nanotechnology based carbon nanotube (CNT) membranes have shown impressive breakthroughs towards water purification as compared to existing energy intensive water purification systems and thus, this technology has immense potential for large scale commercial water purification in a cost effective manner.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. INTRODUCTION Definition: nanotechis the study of the control of matter on an atomic and molecular scale. Nanotechnology uses techniques, processes and materials at the supramolecular level, approximately in a range between 1-100 nanometers (nm), in order to create new properties and to stimulate particular desired functionalities.
7. Application of carbon nanotubes Carbon Nanotubes in Batteries and Capacitors Carbon Nanotubes in Fuel Cell Applications carbon nanotubes with biological systems can significantly improve medical science — especially diagnostics and disease treatment. Carbon nanotubes and graphene exhibit extraordinary electrical properties for organic materials, and have a huge potential in electrical and electronic applications such as sensors, semiconductor devices, displays, conductors and energy conversion devices (e.g., fuel cells, harvesters and batteries). Carbon Nanotubes May Exhibit High Thermal Conductivity
8. Molecular manufacturing molecular manufacturing, is a term given to the concept of engineered nanosystems (nanoscale machines) operating on the molecular scale. It is especially associated with the concept of a molecular assembler, a machine that can produce a desired structure or device atom-by-atom using the principles of mechanosynthesis. molecular manufacturing also has the potential to revolutionize medicine. For example, sensors that are smaller than blood cells could be produced inexpensively. When released into a patient's blood stream in large numbers, these sensors could provide very accuratediagnoses. Nanorobots could be built using molecular manufacturing to perform surgicalprocedures in a more precise way.
9. Nanomaterials Nanomaterials is a field which takes a materials science-based approach to nanotechnology. It studies materials with morphological features on the nanoscale, and especially those which have special properties stemming from their nanoscale dimensions. Nanoparticles or nanocrystals made of metals, semiconductors, or oxides are of particular interest for their mechanical, electrical, magnetic, optical, chemical and other properties. Nanoparticles have been used as quantum dots and as chemical catalysts.

12. Application of nanomaterials Sunscreens and Cosmetics : Nanosized titanium dioxide and zinc oxide are currently used in some sunscreens, as they absorb and reflect ultraviolet (UV) rays and yet are transparent to visible light and so are more appealing to the consumer. Composites : An important use of nanoparticles and nanotubes is in composites, materials that combine one or more separate components and which are designed to exhibit overall the best properties of each component.

20. Food and Nanotechnology Nanotechnology is having an impact on several aspects of food science, from how food is grown to how it is packaged,that will make a difference not only in the taste of food, but also in food safety, and the health benefits that food delivers. Clay nanocomposites are being used to provide an impermeable barrier to gasses such as oxygen or carbon dioxide in lightweight bottles, cartons and packaging films Storage bins are being produced with silver nanoparticles embedded in the plastic.
