Snowflake Chemistry Research



Purdue analytical chemisty graduate student Travis Knepp is growing snowflakes in order to better understand the physical structure of snow crystals, how they grow, and why they take a certain shape. By understanding the chemistry that occurs on the flake surface, Purdue scientist are learning more about the reactions that regularly take place on the snow's surface.

Knepp's quasi-liquid snow crystal research is guided by analytical chemistry professor and department head Paul Shepson. His group is involved with several research projects in the Arctic studying ground-level ozone in the atmosphere.
