Vapor based PEG deposition

In my last post, I introduced the concept of pore size dependent carbon growth on alumina coated membranes. Here, I have plotted a Gaussian fit of the tail of the pore size distribution of carbonized membranes (with and without an alumina coating). I am only showing the tail of the distribution to highlight the sharpness…

SepCon EQ reaches Equilibrium in 2 1/2 hours!w310 (no pinholes)1x PBS (no protein)2 hours @ 1000rpm (3.3psi) -> 103 uL passage (56 uL/(min-cm2-psi) )2 1/2 hours @ 1500 rpm (5 psi) -> 204 uL passage (>74 uL/(min-cm2-psi) ) In the second case, the sample visibly reached what looked like equilibrium. It was not quite exact,…

Introduction The on going work for the dialysis project at UR has undergone changes and many hours of trouble shooting over the past semester. We are at a point now that I would like to share all the work I have done up until this point including assay development, method progression, and the experiments we…

Molar flow thought pores with different diameters under 1 psi. First, I calculated molar flow based on porosity histograms extracted from TEM images. And then compared it with the actual experimental data. Here are few examples of this. molar%20flow.ppt

Based on the talk I gave at the ICNMM (International Conference on Nano, Micro and Minichannels) this past summer, I’ve been asked if I would organize and chair a session titled: Transport in Membranes and Nanofluids. I’d like to include people from NRG as well as membrane collaborators. Consider keeping these dates open: July 10-14, 2016. The conference…

While performing an experiment to study HUVEC growth rates on various substrates, I observed an interesting phenomena on the oxide membranes.  I was using 120nm, nonporous, 600C annealed SiO2 membranes in this trial.  The cells were observed at least once per day over a course of 173 hours from seeding.  The growth rates and quantitative…
