Congratulations on the opening of the company’s website. American scientists are developing quantum wires.Professor Richard Smalley of Rice University in the United States is working hard to develop a world's latest quantum wire. The most research on this kind of quantum wire is Professor Smalley of Rice University in the United States. His successful 15-centimeter-long thin wire drawn from billions of carbon nanotubes represents the first step in a new type of wire that will completely change the transmission grid. This is a wire braided with carbon nanotubes, which can efficiently transmit electrical energy. The laboratory led by Smalley is currently engaged in a four-year project to develop "quantum wires" based on carbon nanotubes. Cables made of quantum wires have a much better power transmission effect than copper wires. Due to the light weight and high strength of this kind of wire, the existing poles can withstand 10 times the transmission power of aluminum cables. Smalley said that quantum wires can at least have the functions of today’s superconductors without the need for expensive cooling systems. The reason is that at the nanometer scale, the mysterious properties of quantum physics dominate. The wires can transport current and have almost no resistance. . The Smalley team has produced a 100-meter-long wire composed of a large number of carbon nanotubes, but this wire is a mixture of more than 150 different types of carbon nanotubes, which limits its conductivity. The best wires will consist of only one type of carbon nanotube. Smalley believes that adding a little nanotube of a single species at the beginning of the manufacturing process may be able to catalyze the production of a large number of the same nanotubes, which is actually "cloning" the original nanotubes. According to CNN, NASA plans to invest 11 million US dollars in the next four years to study the so-called quantum cable, which is planned to be used in aerospace technology and equipment in the future. It is estimated that the electrical conductivity of quantum cables is 10 times stronger than that of copper cables, while the weight is lighter than traditional copper wires. The quantum cable developed by Rice University scientists will be composed of carbon nanotubes, and a prototype quantum cable with a length of at least 1 meter will be provided by 2010. It should be pointed out that the current "wire" made of carbon nanotubes does not exceed a few centimeters in length. Under the condition of successful development, the quantum cable can replace the ordinary copper wires in the spacecraft, thereby reducing the weight of the spacecraft and increasing the mass of the effective load. In addition, quantum cables can also find applications in computer technology and other scientific fields. This possibility is not ruled out. The research results of Rice University scientists can speed up the implementation of the space elevator program. The space elevator is based on a super-strong cable that uses many kilometers to connect a low-Earth orbit space station to a giant platform in the ocean. |
