Lighter than water! New method to design ultra light aluminum crystal
scientists simulated and designed super tetrahedral aluminum crystal that is lighter than water. According to physicists, scientists from Utah State University (usu) and the University of the southern Federation of Russia used computer models to design ultra light crystalline aluminum that is lighter than water. This major breakthrough published in the online edition of the latest issue of the Journal of physical chemistry is expected to be used in the manufacturing of ultra light components in the space shuttle, automobile and other fields
although the traditional form of aluminum crystal is a relatively light metal, because its density (2.7 g/cubic centimeter) is greater than that of water (1 g/cubic centimeter), the spoon made of it will still sink to the bottom after being placed in a water tank filled with water. The density of the new crystal obtained this time is only 0.61 g/cubic centimeter, which is not only significantly lower than that of the traditional metal aluminum, but also means that it can float on the water
in the new research, usu chemist Alexander bordrev led the team to study the elastic modulus and maximum deflection of aluminum and gold at the molecular level It can be divided into simply supported beam zigzag experiment and pure zigzag experiment. The new design is carried out, and the ultra light crystal aluminum lighter than water is obtained through computer simulation. Boulder has a large volume; Digital display temperature value Leifu said: "we used a very creative method to complete this breakthrough - based on the well-known diamond, we replaced each carbon atom with aluminum atom, and obtained tetrahedral crystal aluminum similar to diamond. After further calculation, we found that this is a very stable new ultra light crystal aluminum structure."
because aluminum metal has many advantages, such as non-magnetic, corrosion-resistant, rich content, relatively cheap and easy to produce, this new ultra light aluminum structure will be widely used in the development of lighter space shuttle and automotive components in the future. Bordrev said that although the strength and other properties of this material need to be further studied, and it is still too early to speculate how to use it, the biggest breakthrough of this discovery is that it provides an innovative method for designing new materials. "Our innovation is that we can design new materials based entirely on a known structure."
