Zhang Hongjie, academician of the Chinese Academy of Sciences, academicians of the Academy of Sciences of the Development State, the first batch of experts and members of the review committee of China Science and Technology Think Tank, inorganic chemist, researcher at the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences, and professor of the Department of Chemistry of Tsinghua University.

Zhang Hongjie has been engaged in the basic research and application of rare earth functional materials for a long time, and has developed new methods and technologies for preparing a series of materials. The new rare earth new materials developed have been successfully applied to rare earth AC LED lighting, rare earth environmentally friendly colorant, aerospace high -ultra -wind tunnel temperature measurement temperature measurement temperature measurement temperature measurement , Rare earth magnesium alloy components, national defense military weapons and other fields, meet the national strategic needs.

Fill in the gap in the field of LED lighting in China

Rare earth is known as the "mother of new materials". Its special electronic layer structure has a spectral properties that cannot compare the general elements, which almost covers the category of the entire solid glow, forming a wide range of glow and laser materials, in information, energy, etc. Multiple areas have an irreplaceable position and are national strategic resources. Zhang Hongjie is committed to the research of rare earth for more than 40 years, aiming at the forefront of development, and transforming a number of scientific research results into real productivity, including AC LED technology.

As a new generation of lighting sources, LED lighting is recognized as the most promising lighting industry with the most promising prospects in the world. This worldwide problem. Zhang Hongjie said, "Accelerating my country's LED technological innovation, improving the overall level of the LED industry, and mastering the core key materials and device intellectual property rights are the major needs of the country and the responsibility of our scientific researchers."

After 6 years of unremitting efforts, he led the scientific research team to effectively solve the problem of frequent lighting of LED glowing, developed a new type of rare earth luminous material and AC LED device with independent intellectual property rights, glowing and glowing life, and realized the foundation from the foundation Research to the leap of industrialization has made China the only country in the world to master low -frequency flashing LED products through rare earth fluorescent powder.

At the same time, in terms of the research of rare earth luminescence materials, Zhang Hongjie also led the research team of the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences to cooperate with the wind tunnel temperature measurement unit to solve the luminous efficiency, temperature response range, response speed and heat release of rare earth luminous temperature measurement materials Light interference and other issues broke the blockade of foreign materials and technology in this field. The developed high -sensitivity light -emitting temperature measurement material was successfully applied to a model experiment by the use unit, filling my country's technology gap in this field.

Promote the industrialization of scientific research results

Zhang Hongjie's research span the fields of physics, chemistry, and biological, and research results bloom. He and Wang Yingzhang's research team designed a nano composite material, which can not only improve the effectiveness of chemical dynamics, but also effectively kill tumor cells under the synergy of light thermal and common catalytic effects and achieve tumor tumor Clear completely.

In addition, Zhang Hongjie also cooperated with experts such as Professor Liu Kai to create a new type of high -intensity and supercorpted biological fiber through wet texture methods. This fiber has excellent biocompatibility and excellent mechanical properties, which provides a new paradigm for building a highly powerful protein fiber material. At the same time, its excellent anti -adhesion efficiency is conducive to wound healing. Essence

In terms of the choice of research, Zhang Hongjie believes that it is best to combine the strategic needs of the country, to implement research and contribute to the economic and social development of the country. Just as he made the results of research on rare earth and environmentally friendly colorants, this study lasted for 16 years. The first new method and technique of the first rare earth coloring agent synthesis in the world broke the high production process in the traditional preparation method, and the equipment loss of equipment loss was broken. Large, low output, high cost, cannot achieve an industrialization deadlock. The world's first rare soil color agent continuous and large -scale tunnel kiln production line has been built, which has successfully realized industrialization.

Zhang Hongjie also always thinks about how to combine basic research with applications. He pointed out that the problems encountered by the industrialization of scientific research achievements are closely related to basic research. The more practical the basic research, the more favorable the use of research research. To achieve industrialization, not only must there be a good scientific research team, but also a team of outstanding entrepreneurs with strategic vision. The close cooperation between the team and the deep integration of industry -university -research are the key to success. "Some discovery, some inventions, creation, and progress" can realize the leap from basic research to industrialization. (Kang Wenying)
