Integrated Nano Developer Flow Rates
This experiment compares the metal developer used in Integrated Nano Technologies’ device to to the flow properties of water. Using the pressure cell at 3 psi, with no allyl treatment, for 10 minutes, and 200 microliters of liquid, I pushed water and developer through our membranes and examined the difference in flow rates. All of…
Porosity vs Discoloration I
We have known, W683: no visible pores; W684: very few pores; W685: usual porosity. After Vlassak’s view on discoloration, I took samples from above wafers to check if any difference in discoloration can be seen as they have different porosities. We could expect the more porous material to degrade faster than the less porous and…
Nanoporous SiN Lift-Off Update – April 2015
Background Details: Josh Miller & I have made some recent progress in the NPN LO work. We had several ø6″ wafers w/ 100 nm of thermal oxide processed by Rogue Valley, wherein they deposited 650 nm of poly-Si (LP-CDV) followed by 50 nm of low-stress SiN (LP-CVD). Josh added the a-Si + SiO2 layers at…
pnc-Si membrane from silicon nitride and silicon oxide system
ByJoe QiNow we already confirmed that pores are able to form in both oxide/silicon/oxide and nitride/silicon/nitride system. Here comes an interesting question- how about nitride/silicon/oxide and oxide/silicon/nitride system? In the past week, another two different stacks including SiN(30nm)/ a-Si(25nm)/SiO2(30nm) and SiO2(30nm)/a-Si(25nm)/SiN(30nm) were tested. The nitride film was deposited with 25 W bias and the silicon with…
Transport through 'non-porous' membranes
There’s been lots of discussion about “non-porous” membranes and the possibility that they are actually porous. By “non-porous”, I mean that a TEM of that membrane doesn’t have obvious pores by pore processing/our eyes. This could mean a couple things: either the pores are so small that they are hard to resolve by TEM or…
Plasma Problems
Introduction This post will detail the work completed in the last chapter of my Thesis. The overarching goal of this chapter was to perform dialysis on whole blood utilizing a serial-separation system. This system would first: generate plasma from whole blood and second: remove uremic toxins from plasma employing microporous and nanoporous membranes, respectively. Conducting…

So vapor salinization slows degradation but does not prevent it and L15 is just fine.
1) We’ll need to find more complete surface chemistry to work in general media.
2) We still need to do the ‘reconstitution’ studies to prove that it is a combination of bicarbonate and salts that causes the trouble in DMEM and other media – lets do this next please.
Anant,
If you vapor silane treat the surfaces – but don’t oxidize them beforehand with peroxide – what do you think is happening?
