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.

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
