High-temperature thermal shock and material synthesis: The paper by Professor Li Song's team discussed the application of far-from-equilibrium (FFE) treatment in material synthesis, breaking the traditional thermodynamic limitations through extreme thermodynamic conditions and opening up a new material synthesis path. Flash Joule Heating Machine (FJH) technology can also quickly heat materials to high temperatures, triggering the reorganization of the internal structure of the material and the formation of defects, and achieving precise control of the material's microstructure. Both use the violent reaction conditions brought about by high-temperature thermal shock to promote the efficient synthesis of target materials.
Preparation of non-equilibrium materials: The FFE method "freezes" the material in a non-equilibrium state through an extreme thermodynamic environment, breaking through the stability limitations of traditional thermodynamics. FJH technology is also often used to prepare non-equilibrium materials in the process of material synthesis. For example, in the preparation of carbon-based materials such as graphene, the defect density and electronic structure of the material can be regulated by rapid heating, thereby optimizing its performance.
High efficiency and low cost: The FFE method can complete the synthesis of materials in a short time and is highly efficient. FJH technology also greatly shortens the time of material preparation, improves production efficiency and reduces production costs with its characteristics of rapid heating and cooling. The combination of the two can further improve the efficiency and performance of material preparation and reduce production costs.
Environmental friendliness: The FFE method avoids the long-term energy consumption and environmental pollution problems in the traditional high-temperature treatment process. FJH technology does not require the use of solvents or reaction gases during the material synthesis process, and has low energy consumption. It is an environmentally friendly preparation method.
Further optimization of material properties: FJH technology can be applied to the subsequent treatment of materials treated by the FFE method. Through further rapid heat treatment, the crystal structure and defect distribution of the material can be optimized to improve its performance. For example, more uniform defect distribution and stronger metal-support interaction can be achieved through FJH technology, and the material's anti-sintering ability and long-term stability can be enhanced.
Development of new materials: Combine the rapid synthesis capability of FJH technology and the structural regulation advantages of the FFE method to explore and develop new materials. For example, try to use FJH technology to perform rapid heat treatment and structural optimization on other types of metal oxides or composite materials, and then use FFE method for non-equilibrium synthesis to achieve higher performance and better application effects.
Optimization and standardization of process parameters: In-depth study of the synergistic mechanism of FJH technology and FFE method in the material preparation process, optimize process parameters such as heating temperature, heating time, current density, etc. Establish a standardized process flow to ensure the stability and consistency of material performance, and provide reliable technical support for the commercial production and application of materials.
