Purchasing 101
I figured I’d throw this up in case anyone needed to know how to order anything… enjoy.

Review of ACKD nanotechnology articles (Vol 20, issue 6, Nov 2013)
This is a cursory review of the nonotechnology articles appearing along with our paper in the Journal “Advances in Chronic Kidney Disease” Most of these are reviews and most deal with nanoparticles for either imaging or therapy. One does discuss nanoparticles for use with membranes to improve biocompatibility. I do not have full access to…
Thickness and uniformity of PDMS layers
The last few times the spinned PDMS layers were much more uniform. The first picture below is with 1:100 diluted PDMS layer coated on it and the second one is a clean sample from the same wafer for comparison. The PDMS layer on the first picture is approximately 60nm thick. The measured thikness produced by…
Comparitive Functionalization of pnc-Si measured with f-BSA fluorescence intensity
The last of the larger windowless pnc-Si chips were sent to both Adarza and Dr. Shestopalov’s lab for functionalization. Adarza returned chips with PEG-1 and PEG-2 (different rounds of processing) with both 2 hours and 16 hour treatments. They also returned a set treated with an alcohol leaving group ,ethanolamine (EA). They did also supply…
w677 Separation
Here are the results of a protein ladder separation with w677. If you recall, 677 is the 200um wafer that did not fit into the SepCons but had very few pinholes. S = Standards Ladder, C = Protein solution that never came in contact with membrane, R = Retentate, F = Filtrate Myosin (Band at…
Coating pnc-Si w/ Palladium
I have been working with JP over the past month to attempt to form a thin, continuous film of PdAg on a pnc-Si membrane using e-beam evaporation. The aim of this is to test these for selective hydrogen permeability at elevated temperature for hydrogen purification. We have made three attempts so far. We are using…
Reviewing membrane impact
To identify how much of an effect the membrane has on particular simulations, we originally came up with the idea of using a phenomenological effective diffusion to view the membrane impact (see this post). Here is the most up to date version of the figure, which was slotted for use in the simulated diffusion paper:…
Good Job Derek 🙂
Thanks Derek! I’ll link to this on through the NRG purchasing page.
