1 Introduction
In metallurgy, the central material is an important crystal structure that is closely related to the insulating, conductive, and absorptive properties of metals. The central material consists of a dominant layer and an auxiliary layer. The dominant layer contains metal oxides and openings. The auxiliary layer is an area with a high degree of freedom of the metal, usually a small fluorite-like cell or sheet structure. From a large scale perspective, the dominant layer consists of micropores, microdefects, defect morphology, polarity, titanium structure and other properties, while the auxiliary layer has rich metal network properties and various representation forms, such as lattice nano glue, depleted uranium glue , jelly, micro semiconductors, etc. The Center's materials research focuses on understanding and exploiting these differences in properties to develop new materials with unique functions and create new energy sources or devices. With the advancement of science and technology and the promotion of international competition, the rapid growth and rapid development of China's economy have driven the enthusiasm of scientific research. In recent years, domestic and foreign researchers have invested a lot of resources in the field of metal center materials. However, due to the different perspectives and experience levels of domestic and foreign researchers, there are many aspects of the research that need further improvement. This article aims to combine theory and practice to elaborate on the latest progress in research on metal-centered materials by domestic and foreign researchers, and explore future development directions and challenges.
2. Basic concepts and terminology of central materials
2.1. Central material classification and characteristics
The central material, also known as the crystal structure, refers to a complete chemical product of a single metal that exists alone but is infinitely close to other surrounding molecules. The central material consists of two interconnected layers: the dominant layer and the auxiliary layer. The dominant layer is a thin-walled crystal or microstructure, each layer is embedded with a special function, such as a superconducting strip or diode; the auxiliary layer is generally composed of small particles of free or polymerized nitride, which can independently perform a The functions of the series (e.g. liquid conduction, magnetism) can also be controlled by the outside world (e.g. light emission). Therefore, in addition to structural and functional properties, the central material also depends on a number of other properties:
1. Conductivity: The conductivity of the center material refers to the center
