What is nano-new material?

Nano-new materials are a project in which new nanomaterials created by direct ordering of atoms and molecules are naturally changed within a space of 100 nanometers. Nano-new materials and this field are the starting point for modern power and modern technological innovation. The discovery of new laws and principles and the creation of new ideas give basic science a new opportunity, which will become an important new driving force for reform in many fields. The nano-new material formulation has a lot of peculiar properties due to the small size of SAIZU. In 1988, Baibich et al. found that the magnetoresistance change rate reached 50% in nano Fe/CrMS. It is one level larger than the average ME and is negative. It is the same as GMR. Giant ME was also found in nanosystems, tunnel junctions and Perovskite structures, particle membranes. The Perovskite structure was discovered in 1993 and has a very large ME called CMR. The TMR is found in the tunnel junction. [2] Edit this paragraph material classification

Nanomaterials can be roughly classified into four types: nano powder, nano fiber, nano film, and nano block. Among them, nano-powder has the longest development time and the most mature technology, which is the basis for the production of other three types of products.

Nano powder

Also known as ultrafine powder or ultrafine powder, generally refers to a powder or granule with a particle size below 100 nm, which is a solid particulate material in an intermediate state between atoms, molecules and macroscopic objects. Can be used for: high density magnetic recording materials; absorbing stealth materials; magnetic fluid materials; radiation protection materials; single crystal silicon and precision optical device polishing materials; microchip thermal conductive substrate and wiring materials; microelectronic packaging materials; optoelectronic materials; Battery electrode material; solar cell material; high-efficiency catalyst; high-efficiency combustion improver; sensitive components; high-toughness ceramic material (non-cracking ceramics, used in ceramic engines, etc.); human body repair materials; anti-cancer preparations.

Nanofibers

Refers to a linear material with a diameter of nanometer scale and a large length. Can be used for: micro-wires, micro-fibers (important components of future quantum computers and photonic computers) materials; new laser or light-emitting diode materials. The electrospinning method is a simple and easy method for preparing inorganic nanofibers.

Nanofilm

Nanofilms are divided into granular membranes and dense membranes. The particle film is a film in which the nanoparticles are stuck together with a very small gap in between. A dense film refers to a film that is dense but has a grain size of nanometer. Can be used for: gas catalysis (such as automotive exhaust gas treatment) materials; filter materials; high-density magnetic recording materials; photosensitive materials; flat panel display materials; superconducting materials.

Nano-block

The nano-block is a nano-grain material obtained by high-pressure molding or controlling crystallization of a metal powder. The main uses are: ultra-high strength materials; smart metal materials.
