I’ve been trying to do separations with the NPN 5-slot filters by driving the solution with a syringe pump. This type of separation is required by INT for use in their cartridge. Unfortunately, at most concentrations, solutions with fluorospheres tend to stop flowing after 20-30 µL of filtrate is collected. We believe their is a…
Poor English Paper used as a starting point: Silicon Nitride Etch Rate paper This is a continuation of the work I’ve done, attempting to make freestanding MgF2 nanomembranes (theory and deposition) using a Silicon Nitride nanoporous substrate. I originally wanted to use hot phosphoric acid to remove the Si3N4, but since we do not have that…
Yesterday I posted the results from an experiment testing diffusion of BSA and DDM with salts (10mM) across “treated” and “untreated” SC256 samples. The results posted yesterday showed relatively equal amounts of DDM diffusion in both the “treated” and “untreated” case. For the BSA diffusion however the results showed that a greater amount of BSA…
In my previous post, our urea clearance for the single pass experiments was found to be ~140 ml/min/m^2, which was similar to Fissell/Roy’s value except we used a flow rate of 1uL/min whereas they used a flow rate of 10 ml/min however. To show that we could achieve even greater clearance values than their group…
I carried out the bead assay to monitor membrane integrity in Sepcon format. The sample (no RTP) was taken from #703 and put in DMEM(-FBS) @ RT with membrane side facing up. 15um polystyrene beads were allowed to settle on the membrane and images were taken. As can be seen, the membrane is still intact…
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…
