How water sticks to surfaces

Just to double check the numbers I calculated on Tuesday I ran some wet-wet trials with 100K and 300K Nanoseps. Based on the wet-dry results we would expect that the permeability for the 100K Nanosep would be higher than that of the 100K Microcon. It goes without saying that the 300K Nanosep would also be…

Christine and I have been looking into whether the O-ring position affects transport through pnc-Si transwells.  The hypothesis was that the unstirred water layer under the Sepcon might be diminished by switching the O-ring from its normal position (“O-ring bottom”) at the bottom of the Sepcon to above pnc-Si (“O-ring top” or “pnc-Si bottom”).  This…

We have an STTR grant funding us to revise the Sepcon plastic housing to enable us to do reverse centrifugation easier. As outlined in this previous post, we’re trying to remove unbound IgG from a solution of IgG-antibody conjugates using reverse centrifugation:  The earlier work used Josh Winan’s jury-rigged PDMS-filled reverse centrifugation setup, but despite the…

Hello everyone! I plan to write several posts in the next couple of weeks about the laser annealing of our sputtered three-layer stack. This laser annealing experiment is done at Center for Nanophase Materials Sciences (CNMS) at Oak Ridge National Laboratory (ORNL). It is a collaborational  proposal we submitted at the end of last year…
