Platypus

Over the past couple of months we have run numerous commissioning samples and experiments with “friendly users” on Platypus. In general, we have been fine-tuning our instrumental control and data reduction systems.

Our most recent set of “friends” to visit (photo above with Kwanwoo Shin, left, and Daehyun Hong from Sogang University, Korea) conducted our first serious free-liquid reflectometry experiment: examination of peptide binding to highly charged phospholipid monolayers. Data were taken from DPPS lipid monolayers on D₂O using a NIMA Minitrough under various states of molecular compression.
