Here are some other in-situ heating videos I made recently. First one is NSN30730, which means the Si is 7nm and Si3N4 is 30nm. The speed of the video is 10 time faster than the real time. The first figure is the heating illustration and then comes with the video.
The next is sample NSN301030.

A few weeks ago, I posted discoloration results on carbonized membranes here. It was 6 weeks yesterday since I started this experiment, so I decided to stop it (few, if any, cell applications require 6-weeks of culture). These were SC141 chips in the flat (not transwell) format. I also used DMEM with high NaHCO3 levels. …
I am attempting to manufacture a range of npMgF2 thicknesses as demonstrated in my recent CCD post. Yesterday, I undershot my thicknesses substantially, I believe because of construction vibrations in the building. However, this results in some of the thinnest npMgF2 structure I have ever been able to image. I was targeting 15 nm, but…
Wafer # 4369 (PFI 02) was fabricated with pore sizes ranging from ~550 – 600 nm. Below are two SEM images of the pores, followed by two STEM images. The pores are all open and very well defined. The only defect I could find was a slight stitching offset in the patterning as seen the…
In an attempt to push the cutoff higher, we annealed two wafers outside the susceptor at 1000 C (SC 066) and 1100 C (SC 067) with a ramp rate of 100 C/s. The 1100 C does give a cutoff slightly higher ~5 nm, but I’m not sure if this is within the variability in different…
This post is a continuation of the experiments posted a couple of days ago. In that post, I concluded that absorbance measurements of molecules transported through transwells were not possible if the transwell insert was kept in the 24-well during measurement. This was due to absorbance by the outer walls of the 24-well plate and…
After the disaster with the fridge freezing our gold nanoparticles and causing them to irreversibly aggregate, I figured that it would be a shame to waste the ruined gold solutions and so I took some conductivity and pH measurements with them. I found that conductivity could vary by a factor of 1.5 between the solutions (from…
