Snowflake Chemistry Research
2009-12-09
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.
