US nanotechnology plan for research and development The US investment is equivalent to the amount invested by Japan and EU countries in the research and development of Nanotechnology. This field is equivalent to the investment of Japan and EU countries. The number of scientific papers published in it accounts for approximately 1/4 to 33% of all papers worldwide. US Department of Defense's (DOD) development and applications in naval and aeronautics are the most prominent. The use of nanotechnology in aerospace applications. Nanocomposite coated spacecraft spindles.The main shaft of the spacecraft was coated with a nanocomposite, newly developed coating. This was applied to four spacecrafts. Four years of operation had not resulted in any damage. Nanostructured Aluminium The nanostructured material is subjected to multiple plastic deformations, resulting in an ultra-fine grain structure. By equal channel angular press (equal channel angle pressing), a large number grain boundaries is formed due to an increase in dislocation densities.
The material is further ground on a liquid Nitrogen roller compactor until the particle size reaches 30nm. This method is known as cryogenic compacting. Dispersion oxide and nitrogen particles at grain boundaries to improve dispersion, increase thermal stability and inhibit grain growth. Replace hard chrome with nano Co P plating. This technology was developed by US Department of Defense. Nano Co-P coatings are comparable to or can exceed hard chrome plating. The coating's surface is agglomerate and has no pits, voids or micro-cracks. Originally used for landing gears, it is now used to coat engines and hydraulic piston cylinders. The Co-P Nano-coating developed by lntegran has the following features:

• After 1000-hour exposure tests, Co-P0.05mm nanocrystalline coating was superior to EHC or HVOF.
• According to the ASTMB537 standard, the protection rating of the Nano-Co-P is 8, while that of the HVOFWC Co, Triballoy 400 Alloy coating, is 5, and that the hard chrome coating is less than 2.
• Integran Nanometal composite dies may be used for molds to reduce costs, manufacturing cycles, and mold weight.

Nanotechnology in aerospace. The use of carbon nanocomposite coated is just the beginning. The miniaturization and efficiency of electronic devices, equipment, and components can be reduced. Nanomaterials, on the other hand, can significantly reduce the cost of satellite launches. The application of Nanotechnology in the Aerospace field includes the following:

• Space refractory Polymers such as retractables antennas, solar sails reflectors and living rooms.
• Layered silicone polymer, like impervious container linings, living rooms.
• Conductive coatings for EMI, ESD and optics.
• Space ropes used for space lifts.
• Thin-film photovoltaic solar cells.
• New nanocomposite material for energy harvesting (symbiotic/morphine).
• structure).
• Nanosensor for comprehensive monitoring of health.

NASA and Nanotechnology

• Radhard-based, powerful, low-energy computing system for smart spacecraft.

• The use of small sensors and instruments, which are aesthetically pleasing, allows for the identification and analysis of unknown and changing backgrounds. They can also be used to adapt to harsh environments.
• Nano-rovers, microspacecraft (nanorovers) and satellites with nanoelectronics or nanosensors.
• Materials that are high-efficiency in energy conversion, cryogenic coolers and materials for pre-set sensor and compensation systems to ensure reliability and safety.

Applications of nanotechnology to the automotive industry The automotive industries have used composite metal hydrides, carbon and boron-nitride nanotubes as well as composite metal nitride for hydrogen storage tanks. Nanostructured magnetic magnets are more than twice as powerful as conventional magnets. Solar cell coatings contain nanoparticles. Wetchemicalroute has been used to make cheap solar panels that produce more power. By controlling the size and composition, new alloys are developed with outstanding properties.
Nanocomposite coating A coating in which nanoparticles are uniformly dispersed is used in a window glass as a so SolarCoating. These nanoparticle dispersions are indium tin oxide, (ITO for short),  Antimagne Tin Oxide (abbreviated ATO), zinc oxide (ZnO), alumina (Al2O3) and silver. For example, ITO can be used as a transparent antistatic coating, solar infrared radiation additive and transparent conductive coating, which is an ideal material for window coating. Application of nanotechnology in consumables and daily necessities Aerogel Nano aerogel has excellent performance, can meet the functional requirements under various conditions, is translucent, has excellent heat insulation and noise reduction effect, and is a high-quality material for building and vehicle main window system (fenestrationsystem). Blockcopolymers Nanostrength copolymer wool consists of several different chemically distinct segments. Due to their nature, they can be assembled freely on a molecular scale. Driven by thermodynamic forces, they combine highly polymerized and copolymerized wool in a highly repeatable and highly accurate manner. The result is improved mechanical properties, does not destroy the uniformity of the supporting base metal, and makes it easier to process.
This copolymer is used to ensure the reliability and safety for sensitive composite components, such as aircraft casings. This copolymer is used in many different areas, such as electrical equipment and sports equipment.
