BBB Device V2-8 with vias through bulk silicon

I updated the software for the SSI.  The software seems to be working properly.  There are some differences, most of which I haven’t fully explored.  Notably, we can open and view log files easily with 3.8. It seems that we may need to alter all of our current recipes to make them compatible with 3.8….

In my last post, I presented the results of my BBB TEER experiments.  For the BBB co-culture, there was a spike in TEER.  I hypothesized that this was caused by media acidification by rapidly proliferating glial cells, which in turn negatively affected barrier function of endothelial cells.  When I presented this data to Angela Glading,…

We’ve made a few academic inquiries so far into the theory which governs our nanoporous membrane transfer, but engineers as we are, the pace of our practical knowledge has outstripped that of our theoretical understanding. Here, I want to share a summary of what we know about these transferred membranes from a practical perspective, oriented…

I’ve been working on building a streaming potential/EO device for a while now. This was Yaron’s prototype: Which itself was based on Jess’s design: I didn’t like that the device needed to twist together, and also that it was designed for the old circular 2-slot sepcons. My first prototype used the machine vise downstairs for structural…

I  have attached (I hope) a paper one of my students and I wrote a long time ago on the hardness of porous silicon films vs. porosity etc. The references is Duttagupta,…, and Fauchet, Solid State Commun. vol 101, pp 33-37 (1997). This might be relevant to today’s discussion. Duttagupta1997

This week I’ve added male connectors to my device. Originally, I had female-female tubing connections to the device, which were very prone to leaking around the insertion ports. Tejas suggested that I try printing out the male connectors to combat this problem. The tubing I’m using is ID=2 mm, OD= 5mm. It’s compliant enough to…
