In my continuing efforts (previous post) to create a nanofluidic transistor, I recently repeated some of my earlier attempts to prototype a basic Si-Ag-Al2O3 stack. This time, however, I used SiN chips from wafer #1070 (<40 nm>). As before, I…

In this post I’ve detailed my attempts and eventual success (with Josh’s help) to get the ALD to coat TEM grids without blowing the delicate chips around. The actual technique is at the end of the post, beginning with the…

Here are some images of deposited magnesium fluoride films on 50 nanonitride:              

On Friday, Henry was kind enough to ship 15 tested Sepcons to the Barcikowski group in Essen, Germany. With luck they will arrive in time for Christmas. I wrote up some documentation and an illustration for wetting and using the…

I recently got some good looking results on the FLAG diffusion test over a 24 hour period. The relative concentrations of enzyme seemed to indicate that measurably more enzyme diffused from retentate to filtrate in solutions not containing constricting Anti-FLAG…

We’ve been wondering for some time just how the thinness of our membrane will affect the concentration polarization behavior of solutes. Because solutes with sieving coefficients less than 1 are (by definition) moving slower than the solvent around them, in…

Helpful Hint: H₂O typed as text will yield H2O visually, and E = mc²O typed as text will yield E = mc2. Of course this affects line height, so choose your poison, I guess.

I’ve been on a Sepcon assembly binge, and I thought I would post my assembly statistics. On 12/15/13 (assembly “L”) I broke 28 chips out of wafer 1070. 3 chips were visually damaged by the break-out process, 1 was already…

Images of the nanoporous nitride wafer. The same wafer that Josh declared as having 30% porosity with an average pore size of 80 nm (or something similar). Josh put images and such on basecamp for those who have access. These…
