Nanomaterials: Nanomaterials are the substance where at least one dimension is less than the 100 nanometers. Research in nanomaterials is a field that adopts a science-based approach to materials over nanotechnology. Nanoparticles are objects with the three external dimensions at the nanoscale. Naturally produced nanoparticles or incidental byproducts of combustion processes are usually physically and chemically heterogeneous and are often referred to as ultrafine particles. The designed nanoparticles are intentionally produced and designed with very specific properties related to shape, size, surface properties and chemistry. These properties are reflected in aerosols, colloids or powders. Often, the behavior of nanomaterials may depend more on the surface area than the particle composition itself.

Organic And Inorganic Nanomaterials Nanomaterials Synthesis: The organization of nanoparticles in a thin film form is often necessary to make them functional and operational. Two important chemical methods: * thermal decomposition at high temperature and * liquid-liquid interface reaction, suitable for preparing films of many metal and metal oxide nanoparticles.

Nanomanufacturing involves a larger scale, reliable and cost-effective manufacture of nanoscale materials, structures, devices and systems. It also includes research, development and integration of top-down processes and increasingly complex processes from the bottom up or self-assembly. A.

Appliance Of Nanomaterials: Nanotechnology has already contributed to the number of innovative products in various engineering disciplines due to its unique and rewarding chemical, physical and mechanical properties. One of the popular applications of nanomaterials are nanotubes. Basically, nanotechnology applications can be divided into several categories. Thin films and designed surfaces are adapted to the one-dimensional applications of nanomaterials. They have been used for fields such as electronics and chemistry, so they can not be considered as a new material. A.

The term encompasses a diverse set of devices and materials, with the common feature that they are so small that the interactions between atoms and the properties of quantum mechanics must be studied exhaustively. A nanoelectronic device can be fully functional, the workload it can do is restricted to its size. The basic principle is that the power of a machine will increase according to the increase in volume, but the amount of friction that support the bearings of the machine will depend on the surface area of the machine.

Optoelectronic Devices NanoPhotonics: Nanophotonics or Nano-optics is the study of light and its behavior in the nanometric scale. He deals mainly with optics, optical engineering, electrical engineering and nanotechnology. The nanophotonics are mainly focused on the manufacture and application of nanostructures that facilitate the generation, propagation, manipulation and detection of light from the infrared to the ultraviolet regimes. The term “nano-optics”, like the term “optics”, generally refers to situations involving ultraviolet, visible and near infrared light . Normal optical components, such as lenses and microscopes, generally can not focus light scales to nanometers due to the diffraction limit . It is possible to squeeze light on a nanometric scale using other techniques such as, for example, surface plasmons, surface plasmons located around metal objects at the nanoscale. The scope of nanophotonics extends to theory, modeling and simulation, experimentation, instrumentation and application.

Nanomechanics brings science and applications together on nanoscale and nanostructured materials, with emphasis on mechanics, processing, characterization, design, modeling, and applications of materials containing true nanosize dimensions or nanostructures that describes novel or enhanced properties or functions that are based on tailored nanostructures. Nanomechanics came into existance on the crossroad of solid-state physics, statistical mechanics, materials science, and quantum chemistry. Often, nanomechanics is viewed as a branch of nanotechnology, that is an applied area with a focus on the mechanical properties of engineered nanostructures and nanosystems.A. NanotribologyB.

The proposed designs and designs of these types can be launched individually, or they can have multiple nanosatellites working together or in formation, in which case, the term “satellite swarm” or “fractional spaceship” can sometimes be applied. With the advent of technological advances in miniaturization and capital increase to support private space flight initiatives in the decade of 2010, several startups have been formed to look for opportunities with the development of a variety of vehicle launch technologies.

Nano Robotics: Nanorobotics is the technology to create machines or robots at the scale of a nanometer (10-9 meters) or close to it. Nanorobots can function at the atomic or molecular level to build devices, machines or circuits, a process known as molecular manufacturing. Nanorobots can also produce copies of themselves to replace worn-out units, a process called self-replication. Nanorobots are of special interest to researchers in the medical industry. This has given rise to the field of nanomedicine.
It has been suggested that a fleet of nanorobots could serve as antibodies or antiviral agents in patients with compromised immune systems or in diseases that do not respond to more conventional measures.
