Building on my recent posts I ran an experiment with SC267 testing the ability of BSA and DDM to diffuse through UV-Ozone treated (20min at 150C) and untreated samples. I used four samples testing both BSA and DDM in the treated and untreated cases using Jess’ diffusion cell. Again 6uL was placed on the membranes…

This is just a little update on the results of the pnc-Si, cellulose, and pes separations.  When I added up the retentate and filtrate, it didn’t always equal the intensity of the starting sample (keeping in mind that I was unable to collect filtrate from PES and should re-try that separation). I took the percent…

As a continuation of the substrate bias series, I deposited a 15 nm film with 05 W substrate bias and annealed at 1000 C. TEM shows that this condition generates a 13.4% porosity and a max pore size of ~40 nm! Here is a comparison of all the bias conditions tested thus far: I believe…

This post explains that electroosmosis in our material is higher than we expected. Jim suggested that maybe we don’t have fully developed flow in our thin material. Here I attempt to find the entrance length, or distance until fully developed flow, in our material. One needs to keep in mind that this is a continuum…
