The deposited metal thickness is 20nm, consisting of 10nm titanium and10nm gold. Post not finished. sc b020 – 25nm sc b011 sc b01

A paper by Munch (from Kodak), Zestar, and Anderson in J Mem Sci (1979) writes that charge has a big effect on albumin separations in track etched membranes.  They show in their paper that they can make the theoretical sieving…

I set up diffusion experiments using the wafers that Tom was able to pass gold through in DI H2O using pressure.  5nm particles do not pass in 24 or 48 hours.  If we have extra samples I will be testing…

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 week a set of four wafers was processed at four different RTP temperatures (1000, 950, 900, 850 C).  Unfortunately, the yield across these wafers was low due to possible metal contamination in the film and etch issues.  However, the…

I have been using MatLab to analyze the pores in the SC wafers. Here are the results from my analyses: To take a first look, I simply plotted four characteristics: average pore size, porosity, cut-off pore size, and mean roundness…

I have been working with Barrett to test two different assays with BSA. One is a standard procedure for microtiter plates and the other is a microassay procedure for microtiter plates. Here is a brief summary of each procedure: Standard…

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…
