NanoDays 3/29 & 3/30
We still need help with NanoDays http://doodle.com/paq66krxtf7mt6tk There are two time slots: 10:45am-2pm 1:45-4pm Please wear your I Love Nano shirts from last year. I have a couple more size Medium and one size Small. The Rochester Museum & Science Center is on the corner of Goodman and East Ave.
SEM analysis of NPN membranes post-filtration
As part of the ongoing study of NPN membrane filtration characteristics I used the SEM to look at membranes after they were used. Unless otherwise indicated, files with a “t” (top) indicate the chip was membrane side up. “b” stands for the bottom, or trench side. In a standard forward centrifuge setup we expect the…

The Concentration of the Barcikowski Peptide is at the Lower Bound of Our Detection Limit
Recall that we’ve been having a great deal of trouble following the free ligand during our separations of the Bioconjugated Barcikowski particles, and that this trouble also means we can’t see the ligand after centrifuging the pure sample. In the interest of thoroughness, I replicated the assay the Barcikowski lab used to quantify the unbound…
Updated: 25-40-25 nm OSO SEPCONS
We created a 25-40-25 OSO stack with a SEPCON pattern. RTP at 1050 C 100 C/s 60 s. The following images show a comparison between the STEM detector and the SEM detector, and then a couple more images at 100 kx and 50 kx. I calculated a porosity of ~6.5 %, and…
New Wafers
A few of the newest SC wafers came back with intact samples without any pinholes. First here is a list of the experiments that we want to do in our lab with intact/pinhole free membranes 1. Protein separations – Requires >10 samples per wafer (preferably even more) for replicates of separations in both pressure and…
