Japan has developed the world's smallest diameter carbon nanotubes

The CNRI subsidiary of Japan's Shinshu University and Mitsui & Co., Ltd. has successfully developed the world's smallest diameter carbon nanotube, which is only 0.4 nanometers in diameter.
According to the "Nihon Keizai Shimbun" report, the carbon nanotubes were successfully studied by the research team led by Endo Shinsho of Shinshu University. Prior to this, the world’s finest carbon nanotubes were 1 to 2 nanometers in diameter.
Carbon nanotubes have been attracting attention as a new material with special properties. Because of its high strength, scientists hope to use it as a plastic additive to enhance the strength of plastics, but it is still technically difficult. The emergence of ultrafine nanotubes offers the possibility to solve the above problems. The new nanotube developed by Japan has reached an ultra-fine level. If this kind of substance is incorporated, the nanotubes can be mixed with the resin at the molecular level to form a high-strength plastic, which can be used to make small-precision mechanical plastic gears, and can also be used to make light transparent plastic substrates that are not easily damaged.
In order to make this technology practical, researchers plan to develop technologies to mass produce ultra-fine nanotubes in two to three years.

Round Two-part Lifting Column

The cylindrical tube Lifting Column is a kind of equipment used to control the intelligent lifting table, which is usually composed of a column, a motor, a control system and a power supply. According to different usage scenarios and functional requirements, lifting columns can be divided into the following categories:
Single motor, double motor round tube lifting column: lifting column is usually used for lifting table accessories, smooth and noiseless lifting, can be composed of intelligent lifting table and lifting system.
