Glass Materical


glass materical

Description :

A relatively transparent solid material, which forms a continuous network structure during melting, and the viscosity gradually increases during cooling and hardens without crystallization. The short-range structure is orderly and remote disorder; If judging, the section has shell-shaped section 1. Isotropic: homogeneous glass has the same properties in all directions, such as refractive index, hardness, elastic modulus, thermal expansion coefficient, etc. 2. Metastability: when the melt is cooled into a glass body, it can keep the structure at high temperature at a lower temperature without changing.


In 1992, researchers at the University of California in Los Angeles developed a high-tech colored glass called “smart glass”, which can change color in some compounds. Researchers first use a solution for glass production, and then add enzymes or proteins that can change color in some compounds with extremely high selectivity. When the solution solidifies, one root spun glass is formed around the large protein.
Smart glass has enough holes, such as oxygen and carbon monoxide molecules entering. They react with proteins, resulting in color changes. This smart glass can be used to monitor gases in the atmosphere. If it is made into optical fiber, it can also monitor the gas concentration in blood flow.
