Physical/Analytical Chemistry Journal Club (PACJC)

---

Twice each month, faculty and students gather to discuss physical chemistry. Recent publications are selected to guide discussion on the physical principles behind the work and the methods employed. The seminar was first held in the spring of 2005. For more information contact Kyle McElhoney or Glen O'Neil.

Visitors Are Welcome

Held on alternating Fridays from 4:00 pm to 6:00 pm in Pearson 106.
