The basic research of the design and development of new materials has obtained the first time that the scientist's sculpture is observed on the sculpted scale of a single material-in non-crystal hybrid state

By creating a hybrid structure, the respective advantages of collecting crystal and amorphous state have always been one of the ideal goals pursued by material scientists. Recently, the research team led by Researcher Lu Xujie, a Beijing High-pressure Science Research Center (HPSTAR), used pressure regulation to observe the crystal-amorphous hybrid state at the sub-crystal scale of a single material. A few days ago, related research published a recent natural sub-issue, thesis address: https://www.nature.com/articleS/S41467-022-32419-5.

"The composite of the crystal and amorphous structure in the macro and medium -scale scale has made great progress, and the more micro -scale hybrid structure will have the characteristics of the signs. The challenge. "Researcher Lu Xujie said," For this reason, we proposed a strategy to regulate the chemical keys of the crystal, which will make it possible to design a hybrid structure based on different Asian lattice. "

Dr. Bu Kejun, the first author of the research work and Ph.D. in Beijing Hi-Tech Center, said that this is also the first time that the crystal-non-crystal hybrid state has been observed at the sub-crystal scale of a single material. The cooperative improvement of two mutual competitive physical properties.

Depending on whether the atomic arrangement exists in long -range periodicity, solids can generally be divided into crystal and amorphous state. Different arrangements and interactions between atoms show different physical and chemical properties of crystal and amorphous materials. Each crystal and amorphous materials have their own advantages. How to obtain crystal-amorphous hybrid materials to integrate the structure and properties of these two states is the key to understanding the mechanism of internal interaction, and it is also an important direction for the design and development of new materials.
