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 published 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 an innovative nanocomposite, which was applied on 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 is 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 CoP plating. This technology was developed by US Department of Defense. Nano Co-P coatings are comparable to or can exceed hard chrome plating. It is used to coat engines and hydraulic cylinders. The technology was developed by lntegran. Its Co-P nano coating features:

• After 1000-hour exposure tests, Co-P0.05mm nanocrystalline coating was superior to EHC or HVOF.
• The HVOFWC Co, Triballoy 400 Alloy coating and hard chrome layer are less than 2 according to ASTMB537.
• Integran Nanometal composite dies may be used for mold-making, reducing weight, reducing cost, and saving manufacturing cycles.

Nanotechnology in aerospace. The use of carbon nanocomposite coated is just the beginning. The miniaturization and efficiency of electronic equipment and devices can lower prices. Nanomaterials can also reduce electronic device and equipment costs by a factor of ten. Nanotechnology is used in aerospace for a variety of reasons.

• Space refractory Polymers such as solar sails (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).
• Nanosensors to monitor health in a comprehensive way

NASA and Nanotechnology

• Radhard-based, powerful, small and low-energy computer 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 and satellites equipped with nanoelectronics or nanosensors for in situ testing.
• Nanostructured materials are used for space rockets and large-section structures with high-intensity, including optical, thermal and mechanical materials. Other materials include high-efficiency materials for 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 safety and reliability for sensitive composite components, such as aircraft casings. This copolymer is used in many different areas, such as electrical equipment and sports equipment.
