Sabrina Gericke, William D. Mulhearn, Dana E. Goodacre, Joseph Raso, Daniel J. Miller, Lauryn Carver, Slavomir Nemsak, Osman Karslioglu, Lena Trotochaud, Hendrik Bluhm, Christopher M. Stafford, Christin Buechner
Reverse osmosis using aromatic polyamide membranes is currently the most important technology for seawater desalination. The performance of reverse osmosis

Nanoscale Pattern Decay Monitored via in-situ Heated Atomic Force Microscopy

Author(s)
Sonal Bhadauriya, Jianan Zhang, Jaejun Lee, Michael R. Bockstaller, Alamgir Karim, Richard J. Sheridan, Christopher M. Stafford
We combine in-situ heated atomic force microscopy (AFM) with automated line-by-line spectral analysis to quantify the relaxation or decay of nanopatterned

Insights into the Water Transport Mechanism in Polymeric Membranes from Neutron Scattering
