It was decided during my rotation-review meeting to use a smaller PEG molecule (3-mer) for silanization of pncSi. Following is the brief description of the polymer.   Boiling Point: 147-9°C @ 0.3mm               Freezing…

Previously, I had gotten some inexplicable results showing that increasing salt concentration decreases the flow through a membrane. This makes no sense (and goes against our previous data) because we would expect electrostatic forces to counteract the flow, an effect…

As the device animation shows, the layout of the chip has changed. The incorporation of through-vias in the bulk silicon allows me to eliminate a gasket wrapping around the filter, which was a large source of leaks. I used ozone…
