Here are some high resolution TEM images from a SiMPore-UIUC collaborator. Chris says: The high resolution stuff looks pretty cool, especially the zoom-in on the 8nm pore. I the most obvious crystal planes are <111> with 0.314 nm spacing. If…

Flipped sample discoloration in Sepcon
We have seen before that in petri dishes, flipped samples (well side up) discolor faster as compared to the ‘membrane side up’ samples. This could be due to local environment trapped below the chip. Hence, I used Sepcon format so…
Discoloration in flipped sample – II
I repeated the experiment with samples from #703. Two samples were in a dish with one flipped over. Again, the ‘well side up’ sample (flipped) discolored earlier as seen in the 24 hour time point in the figure below.
Diffusion Gel Reruns
The movable cutoff gels were more or less successful, but were too dirty for publication (see knowledge page). I’ve been trying to rerun them so that they look nicer, but the darker stain that I used has brought out a…

Water Permeability Figure
Previous Post We discussed in meeting having Maryna also calculating the permeabilities for this figure. Here is a figure with the experimental, theoretical permeabilities from Dave’s, Maryna’s, and my processing, and an average of the three theoretical permeabilities. I then…

First TEMs of AJA films
After much anticipation, we have confirmed that pores do form with the AJA deposition system! Below are a series of images of membranes of two different thicknesses that were annealed at several temperatures in the RTP. 1000 C RTP; 40/9/40…

Intact pnc-Si with HUVECs after 1 week
My last cell post involved pictures of HUVECs after 1 day of growth on commercial transwells and pnc-Si Sepcons. Over the past week, I’ve been growing HUVEC on commercial PC transwells and pnc-Si in the Sepcon format in order to…

Discoloration – autoclave #2
I repeated the autoclave experiment from earlier this week, but this time I also used the Sepcon format. I used wafer 662, which was contaminated with large spots. This was done in the oven in RPMI-1640 with FBS (no RTP). …

Discoloration in a flipped sample
I am not sure what prompted me to carry out this experiment. I took few samples from W703 (No RTP) and put them in petri dishes with DMEM (-FBS) at room temperature. I had two samples in a dish, with…
Discoloration in Sepcon
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…
