Raw Data (including preliminary models) and Figure Drafts for the Modeling Paper
Below are drafts of all the figures I am planning on incorporating into my upcoming model paper. I believe I am done with data collection at this point. Data in figures not marked “NEW” probably needs to be updated. Note that all model curves are calculated with no fitting parameters. They are derived from base principles. That’s why…
Vinculin and Focal Adhesion Experiments on TCP
Purpose: To investigate the formation of focal adhesions (FAs) on various cell culture substrates, including TCP, SiO2 membranes, and PDMS membranes. Background: FAs are large macromolecular assemblies through which mechanical force and regulatory signals are transmitted between the extracellular matrix (ECM) and an interacting cell. FAs consist of a complex network of ECM, membranes, and cytoplasmic components…
Updated Hydraulic Permeability Plot
ByJimHere is a look at all our water permeability through nanomembranes to-date. There appears to be subtle trends showing increasing permeability with radial position (r – values) and a not-so-subtle trend showing decreasing flow with protein (cyt and albumin). Note that with the more recent membranes we’ve been able to do repeats. The permeabilities are…

Carbonization is time dependent
After seeing a reduction of pore size at 750 C, I decided to run three different soak times at a fixed acetylene concentration of 1 LPM. As expected, the longer soak time resulted in more occlusion. It seems that the carbon growth is almost linear: 5 min treatment shrinks the pores by 5 nm and…

This is all great data. Have we made any progress in mapping the flow rate to the pore size distribution and porosity of the membranes?
