For the modeling paper, I had to precisely quantify the distribution of gold nanoparticles in the BBI solutions. To do this, I dried the stock solutions of particles on TEM grids (I don’t know what chips I used, but I seem…

Using Alumina Deposition to Modulate Pore Size
The Cambridge Microsystems Savannah 200 atomic layer deposition (ALD) system uses a two-step chemical process that alternates pulses of water vapor and trimethylaluminum (TMA) to build a layer of Al2O3 on a silicon substate. Because of the two-step nature of…
SEM Images of Barcikowski Samples
With Joe’s help, I was able to take some SEM images of the samples that I performed my previous set of separation experiments on. Sample 1: The obvious aggregation in this sample (exemplified by the ‘victory eagle’ blot in the…

Barcikowski Collaboration Rotation Project
As a rotation student from the Biophysics depart, I’ll be spending the next six weeks or so helping Dr. Stephan Barcikowski use the nanomembranes to do a number of separations as part of a nanofabrication procedure. Dr. Barcikowski makes extremely…
Pressurized Gold Separations – Part 3
Dan Mendelson performed gold separations using wafer 255 and has shown that this wafer has a cutoff for gold near 25 nm. Below I have plotted the data of filtrate gold concentration as a function of the feed concentration for…
