Cell Spreading on pncSi and glass

So I think I have confirmed that PDMS is at least one of if not the major contributor to the contact angle problems in the UV-ozone system. Control image before any treatment: I then dried the chip and placed it in the UV-ozone system with two slides that each had two strips of PDMS. Since…

Recently, I have been exploring the temperature dependence of post-Si deposition Ar sputtered films (15 nm thick). Below is a comparison of the average pore size, porosity, and density of pores of Ar and non-Ar sputtered films annealed between 800 C and 1100 C. It appears that Ar sputtering increases the avg. diameter and porosity…

I ran the same 100K microcon system through numerous pressure ranges and put together the spread of hydraulic permeability results.These results show that the hydraulic permeability of the microcon membranes decrease with increasing pressure. Once I finished running the tests at these pressures I reran a test at 19.52psi (3800RPM) to see if we would…

Hopefully in the next week we will be submitting the following manuscript … X. Li, D. Johnson, W. Ma, H. Chung, J. Getpreecharsawas, J.L. McGrath, A.A. Shestopalov, Modification of Nanoporous Silicon Nitride with Stable and Functional Organic Monolayers, ACS Chemistry of Materials  (2016) submitted. Here are the highlights … Traditional silanization of silicon materials uses…

  Overview I burst pressure tested TEM chips with 1×1 mm windows of 100 nm SiO2 that were both annealed and unannealed (provided by JP and Josh Miller). In our experience it seems that the forming gas (H2/N2) annealed chips are stronger and never wrinkle. These burst pressure tests were performed in an attempt to…

My previous 2 posts on co-cultures presented images but I also tracked the TEER in these experiments.  This post shows that data. The top 2 graphs are from the 1st co-culture experiment – the bottom graph is from the second experiment (where my PET controls died), as % Day 0: On PET, the coculture TEER…
