These are the graphs with burst pressures for wafers 187, 189, 310, 312 and updated burst pressure book

The orange columns in the graphs indicate samples that I used for air permeability tests before.
Intro Understanding how the Au film coats the inner part of the npMgF2 is essential to understanding how the photonic properties of the npAu/npMgF2 sensor arise. From SEM, we are able to resolve little cones of Au, but unable to see how rough/homogeneous/open the Au layer is. Our hypothesis is that these little cones of…
The development of the μSiM-DX has been swift and focused, as discussed in these previous blog posts: https://trace-bmps.org/beadazzled-laying-the-foundation-of-the-%ce%bcsim-dx-fouling-based-sensor/ and https://trace-bmps.org/vindictive-virus-capture-testing-the-%ce%bcsim-dx-with-vaccinia-virus-towards-a-modular-virus-diagnostic/. To provide a greater understanding of the inner workings of the device, I have done a few calculations regarding some of its working properties related to microfluidics. The three I present here are about the relationship…
Adeel and I summarized our key takeaways from the BMES in this post. I personally tried to attend organ on a chip talks and posters, which included a micro- or nano-porous membrane or a micro/nano-structured co-culture system. I tried to identify weaknesses and strengths to highlight our potential opportunities to contribute, and to improve our…
We have seen that discoloration of chips is slower in Sepcons and this has been speculated to be because of the separation between the ‘well side’ and the ‘membrane side’ of the chip existing in the Sepcon format. To further provide evidence to this theory, I carried out an experiment monitoring the discoloration of samples…
I had some old carbonized samples kicking around and decided to do some high res TEM yesterday to see what a completely occluded pore looked like. Below is an image showing a blocked pore and adjacent Si nanocrystal. Inside the pore, you can see concentric “rings” of carbon atoms i.e. graphene sheets? Here is a…
I took some force curves a while ago to see if there was any difference between wrinkled and taut membranes. Here, I present only the data with a 15nm ‘trigger’. The trigger is a user-defined parameter that sets the maximum deflection of the cantilever during a force curve acquisition. THe y-axis in these graphs is…

Thanks Maryna. I’m glad to see that we are breaking the 10 PSI barrier again!! Do the numbers on the x-axis correspond to position on the wafer? I assume the the stronger samples are from the center, where the porosity is lower?
Please let us know. Thanks!!
X-axis numbers don’t correspond to position but most of the “over 10psi results” are form the samples close to the center or in the center.
Maryna,
Could you label where the samples came from? It would be nice to see a trend based on the location from which the membranes came from!
