He has received numerous awards, including the Special Award of the CAS President’s Scholarship (1991), the Second Prize for Technological Invention from the Chinese Academy of Sciences (1998), the First Prize in Natural Sciences of Liaoning Province (2005), the Second Prize for National Scientific and Technological Progress (2014), the Global Star Award of the American Ceramic Society (2010), the Bridge Building Award of the Engineering Ceramics Division of the American Ceramic Society (2018), and the Contribution Award from the International Centre for Diffraction Data (ICDD) in 2009, 2012, and 2014. He has also been supported by the National Outstanding Youth Fund (1999) and the Chinese Academy of Sciences’ Hundred Talents Program (2003).

Professor Liu Jiachen is currently affiliated with the Department of Inorganic Nonmetallic Materials at the School of Materials Science and Engineering, Tianjin University. His primary research interests include oxide-based structural ceramic materials, high-temperature thermal insulation and sealing materials, and deep-sea buoyancy materials. He has led and completed four National 863 Program projects, four National Natural Science Foundation General Projects, and more than 20 applied research projects. He has published over 100 academic papers and received one Second-Class Award for Technological Invention from the Ministry of Education.

Paper Introduction:

Professor Zhou Yanchun’s research group and Professor Liu Jiachen’s research group at Tianjin University jointly published the paper “High entropy (Yb” _0.25 Y _0.25 Lu _0.25 Er _0.25)₂ Silicon dioxide ₅ “With Strong Anisotropy in Thermal Expansion” was published in the Journal of Materials Science & Technology, which is classified as a Zone 1 journal with an impact factor of 5.04. This paper was awarded the Second Prize under our company’s Paper Award Program.

Central Instruments:

The TA-16A01 high-temperature deformation visualization analyzer used in this paper was provided by Tianjin Zhonghuan Electric Furnace Co., Ltd., which is also specifically acknowledged in the manuscript. We would like to express our gratitude to the faculty for their recognition of Tianjin Zhonghuan Instruments. Tianjin Zhonghuan will continue to support researchers in their scientific investigations and technological innovations.

Equipment Introduction:

The visual high-temperature deformation analyzer consists primarily of an intelligent heating system, an automated sample-delivery system, a custom LED blue-light telecentric illumination source, a high-precision optical imaging system, and an image-processing system. The intelligent heating system enables multi-stage, segmented, and highly precise control of the sample sintering schedule; the high-precision optical imaging system allows for accurate measurement of changes in sample dimensions and shape; and the automated data-acquisition and processing system presents sample expansion and contraction in graphical form, providing intuitive and reliable visualization. This instrument is used in materials research and development as well as manufacturing, helping to precisely optimize sintering and heat-treatment processes, improve product quality, and reduce production costs. It is widely employed for the analysis and testing of high-temperature material properties across a variety of materials, including ceramics, ceramic glazes, refractories, and minerals.
