CREEP host institution: University of Mainz, Germany
I received a three-year Ph. D. training in Johannes Gutenberg University Mainz, Germany, as a Marie Curie Actions H2020 ITN Research Fellow focusing on the rheology and deformation of glass under extreme conditions collaborated with the SCHOTT company. In these three years, I applied many geological high-pressure apparatuses to study the pressure dependence of the glass relaxation and flow near the glass transition region. To explain the experimental data, I used several mathematical models, e.g., a new relaxation model, an extended Arrhenius model, and the multi-Maxwell model. The previous work achieved a significant impact on the understanding of necessary features in models describing the visco-elastic behavior of industrial silicate glasses at high pressure (comments from the SCHOTT company). And I had good cooperation with several labs, including the high-pressure lab in CNRS, University of Montpellier and the high-pressure torsion lab in the University of Vienna. Moreover, I also have some numerical modeling experiences on the glass deformation and flow process by applying the geological numerical codes LaMEM and MVEP2 from the geodynamic group of Mainz.
Besides, my master study is focusing on the recycling of industrial waste to glass fiber and glass-ceramic products, thus, I have a strong interest in industrial waste management and waste-derived novel materials development. In 2015, I joined the large engineering project (collaborated with Baosteel in China), which has successfully demonstrated recycling molten blast furnace slag into short glass fibers at an industrial scale. The study of recycling industrial waste to glass-based products can benefit both economy and environmental protection which is also my lifetime research topic.
For future research, I am interested in (i) studying the glass transition and flow under high pressure at both micro and macro scales and combining with some molecular dynamic modeling to derive a universal pressure dependence of glass transition and relaxation behavior for glass; (ii) industrial waste recycling to novel glasses; (iii) numerical modeling of the glass production process.
