Nanotechnology is an emerging new technology which is born in the late 1980s. It refers to the materials and products with 0.1 ~ 100nm size range. The study is about the interaction of electrons, atoms and molecules in the system. Its purpose is the direct manipulation of electrons, atoms or molecules according to people’s will.
Nanotechnology is a highly cross discipline including the physics of nanosystems, nano chemistry, nano-materials science, nano-biology, nano electronics, nano processing, nano-mechanics and nano-mechanics. Nanotechnology has been applied as building materials, optics, semiconductor, information, communications, military and other fields. At present, the nanomaterials technology is the only one nanotechnology which can be realized.
The surface effect of nano materials manganese powder increase the activity of nano-materials, nano metal powder has two special properties, one is the strength of the nano metal powder, high hardness with decreasing grain size, the strength, hardness continuous improvement also showed very good plasticity and toughness; second nano metal powder is a good absorbing materials. The special properties of the nano metal powder, if it is mixed into the cement in concrete can be made a function of the electromagnetic shielding concrete.
Nano-TiO2 is an excellent photocatalyst, it has air purification, sterilization, deodorization, surface self-cleaning and other special features. The use of nano-TiO2 air purification features to prepare photocatalytic concrete photocatalytic reaction, decomposition of the motor vehicle emissions of sulfur dioxide, nitrogen oxides and other harmful pollutant gases in the purification of the exhaust of motor vehicle exhaust removal and plays a role of cleaning air.
The nano-metal boron powder oxide materials can be used for electromagnetic shielding. It can also be used for the preparation of smart cement concrete, such as self-police cement concrete. Cement concrete has strong conductive properties, while also has sensing role. Intelligent cement concrete can be used for real-time and long-term monitoring of civil engineering structures. It is easy to monitor the cracking of the concrete structure and the destruction of its damage evaluation, testing, vehicle weight and vehicle speed. This is a revolution for the detection of concrete properties.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
