High-temperature thermal shock and material modification: The paper by Associate Professor Zou Jingyun's team introduced the carbon thermal shock (CTS) technology, which achieves heating and material modification through the synergistic effect of carbon materials and power sources. 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 achieve precise control of the material's microstructure. Both use the violent reaction conditions brought about by high-temperature thermal shock to promote efficient modification of target materials.
Rapid heating and nanomaterial synthesis: CTS technology shows great potential in the synthesis of nanomaterials. Various nanoparticles, including metals, metal compounds, and high-entropy alloy nanoparticles, can be prepared through top-down or bottom-up strategies. FJH technology is also commonly used for rapid heating and synthesis of nanomaterials in the preparation of other materials. 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: CTS technology has the advantages of rapid response, high efficiency and large-scale production capacity, which can promote low-cost green manufacturing of nanomaterials and micro-nano devices. FJH technology also has the characteristics of rapid heating and cooling, which greatly shortens the time of material preparation, improves production efficiency and reduces production costs. The combination of the two can further improve the efficiency and performance of material preparation, reduce production costs, and provide technical support for large-scale production of high-performance materials.
Environmental friendliness: CTS technology does not require the use of solvents or reaction gases during the material synthesis process, and is an environmentally friendly preparation method. FJH technology also does not require the use of solvents or reaction gases, and produces less waste during the material synthesis process, which meets the current requirements of environmental protection and sustainable development. The combination of the two helps to achieve a greener and more sustainable material preparation process.
Further optimization of material properties: FJH technology can be applied to the subsequent treatment of materials treated by CTS technology. Through further rapid heat treatment, the crystal structure and defect distribution of the material can be optimized to improve its performance. For example, FJH technology can achieve more uniform defect distribution and stronger metal-support interaction, and enhance the structural stability and catalytic performance of the material.
Development of new materials: Combine the rapid synthesis capability of FJH technology and the material modification advantages of CTS technology to explore and develop new materials. For example, try to use FJH technology to quickly heat treat and optimize the structure of other types of carbon materials or composite materials 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 CTS technology 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 guarantees for the commercial production and application of materials.
