I guess there was a mistake in the last permeability plot.  The real data for the 4 bar plot should look like this: Unfortunately that doesn’t look so good anymore.  The third bar though is the one that I originally…

I’ve prepared a few slides of discoloration data for tomorrow.  The images didn’t copy over from the blog very well, but I think they are good enough for a discussion. labmeeting_oct211

More discoloration experiments.  No wafers were RTP’ed, and I looked at different wafer numbers.  For each experiment, I looked at discoloration in the oven at 37C and the incubator.  The labelling might be a bit confusing.  For the top right…

In my previous post, there still appears to be a discrepency between the calculated pore statistcis and the experimental permeabilities. I explored what I could do with the pore processing to bring the experimental closer to the calculated permeabilities. I…

A couple weeks ago, I posted some pictures that showed a non-linear “dose-response” curve for NaHCO3 and discoloration in the incubator (post).  I repeated this experiment at 37C in the benchtop oven.   These pictures show that there was a…

Bernhard Group: Discoloration was observed during DNA separation experiments.  Further study led to these results: No discoloration observed with low pH buffered NaCl. Discoloration with high pH buffered NaCl. Worried that Cl was the culprit, sodium acetate was tested.  Discoloration…

Since Jess saw discoloration last week within a day in PBS with the new material, I did a couple of discoloration studies this week.  I looked at wafers 670 and 673 and compared them to 625, 704 and 680-T.  These…

I got back on the AFM today to rescan the wafers from yesterday and too scan a wafer that Dave had given me a few weeks ago.  The 2 panels are from the height channel, I used the 240 tip…

I posted some pictures yesterday from AFM last week.  I got back onto the AFM today and re-scanned the megasonics cleaned virginia semiconductor wafers.  For each image, the top and bottom panels are the height and ZSensor scans, respectively.  All…
