Ever wonder what ozone looks like when it’s adsorbed on silica gel at -40 oC? Purple!

Ellie Siegfried and Liam Kollar have been volunteering in our lab this semester. Because they were first-semester Bucknell students, they haven’t been able to spend much time in the lab yet, but hopefully they’ll be around for a while!

It was great to see Carmen (Gherghisan) Vanderhoof and Rebecca Rupp, two of the very first Castle group members, back for the class of 2015 reunion this weekend!

The new ozone freezer is up and running and working great! No more constantly icing cold baths, just a stable flow of nearly pure ozone. Thanks to NASA for making the upgrade possible!

Conor is off to a great start learning the ins and outs of the lab. He’ll be designing his MS project over the next few months.

The Castle Group welcomes Kat Klein back to Bucknell as she begins pursuit of her MA degree in chemistry.  Kat received her BS degree in chemistry from our department in the spring of 2013 and spent the last year working as a high school teacher in the Lewistown area.  Kat’s project will involve exploring the feasibility of measuring energy transfer between water vapor and oxygen atoms using a quantum cascade laser.

Congratulations to Castle group members Steve Allison, Michael Jelencic, Alex Kowler, and Rene Talai on achieving their BS degrees this spring!
