Dear all, I hope you are all doing well. Based on Doodle poll survey, Friday is the most appropriate time for a coffee hour when most students can attend. We will keep the coffee hour on Friday, and move the NSAC Journal Club on Tuesday so that most students can attend them. This week, we have the first coffee hour of this academic year. Vasudevan Iyer, a Ph.D. student working in Prof. Xianfan Xu's lab is going to give the talk on "Infrared ultrafast dynamics in black phosphorus". Please join us this Friday at 3:30 pm in the BNC Atrium. *What: NSAC Coffee Hour talk* *When: Friday, September 8th, 2017 3:30 pm* *Where: BNC Atrium* Speaker: Vasudevan Iyer Coffee will be served.
