ICNMM Slides

From the last post, I had successfully manufactured waveguide on top of our porous silicon nanomembrane chip. However, the proof that light can transmit through the waveguide was not accomplished until last week. The problems I was experiencing included insufficient thickness and wrong cladding layer refractive index. Thus, in order to prove that my waveguide…

On Friday Josh and I assembled  Sepcon chips with calculated porosity of ~6.5 %, and avg. pore diameter of ~40 nm into Sepcons.   I was able to pass 40nm gold through the pores (we don’t have any gold larger than that).  Note the “Bad” retentate – for some reason one of the sepcons didn’t filter anything. On…

This is a reprisal of the old post. While manufacturer declares particles to be 5, 10, etc, they do however give a measured average to their particles in the written material they provide.  I did not have that in the last chart.  Here I also add the standard deviation of TEM and Malvern data (as…

I ran some tests today using the 0.01um, 0.05um, and 0.10um pore diameter track-etched membranes from sterilitech. The tool the paul built to cut the membranes works very well, and assembly into the microcon systems it simple. I used the standard vertical-wall o-rings that come in the microcon systems because based on yesterdays test results…

In the wake of the apparent loss of all of the phosphatase in a sample that was placed into a CytoVu well, left for 24 hours, and then checked for phosphatase activity, it’s become clear that the adsorptive qualities of the CytoVu assemblies needs further characterization. I showed in an earlier post that there was some loss…

The permeability data is very different for films deposited at room temeperature and 400C.The 400C deposited wafers have much higher permeability and more consistent. w335 – RT w336-RT w338 -400C w340 – 400C Burst Pressures
