My recent work has focused on wetting the inner portion of an attocavity with isobaric cooling to create condensation. We are trying to attack the problem of wetting through the nanomembrane without breaking the membrane. A perfectly dry membrane will always…

This blog is to revisit the old TEER data obtained by Barrett from the coculture experiments on pncSi and polymer membranes. The reason behind this analysis is to understand the differences of the raw resistance values obtained for the same…

I wrote about my experiences tenting nanomembranes here. I delaminated NPN material across a bunch of substrates and found that the film would actually form a nanocavity if spread across a sufficiently small surface (I estimated it to be 1-2…

Background Details: Josh Miller & I have made some recent progress in the NPN LO work.  We had several ø6″ wafers w/ 100 nm of thermal oxide processed by Rogue Valley, wherein they deposited 650 nm of poly-Si (LP-CDV) followed…

These fits are done using the math outlined in this previous post. We assume an average pore size of 50 nm and an approximate number of pores in the membrane of 1E9. 20 nm particles:   100 nm particles:  …

I was not entirely satisfied with the amount of data that I received from my last burst pressure wafer, so I processed another wafer. This wafer had some yield loss initially, as well as window sizes that were slightly smaller…

In my previous post, I derived a formula for the time-dependent flux decline in a centrifuge-driven membrane separation, assuming that the resistance of the membrane was held constant. The problem with that approach is that, as Josh discusses in this…

Kevin Healy is a Phase I and Phase II awardee of the NIH Tissue Chip initiative. The goal of this initiative is to create ‘mini-organs’ ‘organs-on-a-chip’ ’tissue chips’ or ‘microphysiological systems’ (MPS) for higher throughput and more reliable drug discovery.…

I was given three groups of chips to SEM. The first group had undergone the Diazerine and PEG1000 treatment followed by incubation with either PBS, IgG, or BSA. The second ‘group’ was a chip that had been treated with diazerine…
