Numerical Simulation of Freckle Defects in Nickel based Superalloys
Journal of Harbin University of Science and Technology, 2020 In order to deeply understand the formation characteristics of freckle defects in the process of directional solidification of nickelbased superalloy, three major equations of fluid mechanics were used to simulate the formation of freckles during the ...

The impact of the solidification rate on purification polysilicon by directional solidification
Journal of Physics: Conference Series, 2022 Abstract In this experiment, directional solidification method was used to prepare metallurgical grade silicon ingot. We have studied the solidification rate which influenced the results of the experiment. Experimental results showed that the impurities were concentrated mostly in the top of silicon ingot.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis
FEBS Open Bio, EarlyView.Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.
