Gold sieving graph with all my data and model lines

Last week I made a post about the troubles that a toluene-based PEGylation process presents to the PDMS in the CytoVu assembly. It was suggested that this issue might be overcome by replacing toluene with ethanol in the process, but I can report that unless I did something wrong (which is, I suppose, quite possible)…

The hydraulic permeability of a membrane is the inverse of the fluid resistance normalized to the membrane area. Experimentally it is found with Where Q is the measured flow rate, is the pressure drop across the membrane and is the membrane area. It can be calculated from membrane properties with Where is the fluid resistance…

Hi all, Previously we described a two-compartment flow system integrated with a nanoporous membrane in between; and we showed that the nanporous membrane effectively reduces fluid flow from one compartment to the next. Seeing that today is our last NRG meeting this summer, I will present a revisit to the prediction of flow distribution within the membrane-based…

A droplet (3uL) of 0.117 uM actin solution was added on membrane W303(0,2). Let the membrane sit in humidity Chamber for 20 min. Remove excess liquid. Add equal volume of Uranyl Acetate on membrane. Wait 90 sec. Remove excess liquid. Image was taken right after sample preparation. Xiao

EO tests were continued using 2 micron carboxylated PS Latex beads in a 0.2 mM K2HPO4 solution containing 0.1% tween. The solution had a pH of 7.54 and a conductivity of 67.0 uS/cm. The beads were negatively charged, and so would move towards the positive electrode absent electroosmotic flow. It was suggested that the pump…

Images of the nanoporous nitride wafer. The same wafer that Josh declared as having 30% porosity with an average pore size of 80 nm (or something similar). Josh put images and such on basecamp for those who have access. These numbers are for a TEM grid from near the outside edge of the wafer, where…
