Changjiang Daily Rong Media News, May 2 (Reporter Wang Daqian) April 25, 2018, organized by the Chinese Vacuum Society, the team of Huazhong University of Science and Technology "Yangtze River Scholar" Professor Miao Xiangshui and Wuhan Jiayitong Technology Co., Ltd. The appraisal meeting for scientific and technological achievements of "Thin Film Material Thermal Characteristics Testing Technology and Instruments" was held in Wuhan.

The meeting was presided over by Liu Feng, Executive Deputy Secretary-General of the Chinese Vacuum Society. The appraisal committee was chaired by Academician Zhang Lianhe of Wuhan University of Technology, Professor Pan Feng of Tsinghua University, Professor Han Gaorong of Zhejiang University, Researcher Ren Lingling of the Chinese Institute of Metrology, and Professor Zhu Jiaqi of Harbin Institute of Technology , Professor Zeng Dechang of South China University of Technology, Researcher Wu Zunhong of the Special Equipment Inspection and Testing Institute of Hubei Provincial Quality and Technical Supervision Bureau, etc. participated as experts in the results appraisal meeting.

New materials are the five major disruptive technology areas that the country focuses on deployment. Disruptive new materials urgently need disruptive testing technology. The vigorous development of my country's 2 trillion new materials industry has given birth to a huge demand for materials testing instruments. Thin film is the current development trend of the new material industry. As the thickness of the film is gradually reduced to the nanometer scale, traditional thermal property testing instruments are helpless to test the thermal properties of nanoscale thin film materials.

After seven years of hard work, Huazhong University of Science and Technology and Wuhan Jiayitong Technology Co., Ltd. focused on "thin film material thermal characteristics testing technology and instruments", breaking through the limitations of traditional thermal analysis instruments for low-dimensional material thermal characteristics testing, and succeeded A series of thermal characteristic testing technologies and instruments such as phase transition temperature, thermal expansion coefficient, thermal conductivity and Seebeck coefficient of thin film materials have been developed, and more than 100 units have been sold, and demonstration applications have been implemented in more than 30 units and exported to Overseas markets such as the United States and the United Kingdom have brought better economic benefits. The project has obtained 25 authorized patents, and the instrument won awards such as "Top Ten Scientific and Technological Events in Hubei Province" and "Top Ten Most Influential Scientific and Technological Events in Wuhan City". The homepage of the official website of the American Ceramic Society published a promotional video for the thin-film thermal analysis instrument developed by the project technology, and reported that "a seemingly impossible experimental data was obtained." Its test method has been cited many times by international authoritative journals and scholars in the field of materials.

In the early morning of the 25th, Researcher Ren Lingling and Researcher Wu Zunhong came to the site to conduct field tests on the indicators of the four instruments of the appraisal results and issue test reports. The meeting officially began at 15:00 in the afternoon. At the meeting, Liu Feng, the executive deputy secretary-general of the Chinese Vacuum Society, announced the approval documents of the appraisal meeting and the list of experts of the appraisal committee. Subsequently, the project leader, Professor Miao Xiangshui, from the background, current situation, technical principles of the invention, core patents, performance comparison with existing instruments, and the economic and social benefits generated after the industrialization of the project, gave you all the information The experts gave a detailed report, which was unanimously approved by the members of the expert group. Afterwards, the project team member, Tong Hao, read out the findings of the novelty search. Researcher Ren Lingling, the leader of the test team, introduced the test results of the appraisal project, and the user representative introduced the application of the appraisal project in the company.

After the project report, members of the expert committee inspected the project results on-site and listened to the project team members’ explanations on the technical principles, R&D process and application of the project. Academician Zhang Lianmen and experts highly appreciated the project's innovative work in the detection of low-dimensional material thermal properties, thought it was very ingenious, and gave very good suggestions. Since then, the project leader Professor Xiangshui Miao and the members of the project team gave detailed answers to the questions raised by the experts.

Finally, the appraisal committee unanimously agreed that “the achievement is outstanding in innovation and is at the international advanced level as a whole. It has reached the international leading level in the phase transition temperature test of the nano-scale film and the in-plane thermal conductivity test of the film.” And unanimously agreed to pass the appraisal.
