Gene vs Protein nomenclature

After the disaster with the fridge freezing our gold nanoparticles and causing them to irreversibly aggregate, I figured that it would be a shame to waste the ruined gold solutions and so I took some conductivity and pH measurements with them. I found that conductivity could vary by a factor of 1.5 between the solutions (from…

Hello everyone, for my first ever post I would like to share with you a collection of ideas that has turned into a review I’ll be working on. Here you will find some selected publications that report interesting fabrication processes at the nanoscale. I have summarized the processes and added some raw schematics of how…

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 numbers are for a TEM grid from near the outside edge of the wafer, where…

We’ve known for some time that the sieving coefficient of our membranes changes over time. The reason for this is that at the start of the separation the concentration just above the membrane is the same as the bulk concentration, but as more and more fluid begins to pass through the membrane we get concentration polarization, and the membrane…

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 defective. After inserting the chips into the sepcon housing, testing with 5 psi nitrogen revealed…

During the last weeks of my rotation, Tejas and I attempted to study neutrophil migration in the following setup, using fMLP as a chemoattractant: In order to do this, we permanently bonded a 1 mm PDMS gasket to the bottom and top sides of a 3 micron microporous SEPCON and filled the back side (which is…
