How water sticks to surfaces

It is well believed that the pore formation is directly related to the silicon crystallization. In this post, I’m gonna further show that how does the crystallization process affect the pore formation. The crystallization process can be divided into two stages. The first one is the nucleation of silicon atoms. In this stage, crystal nuclei…

Here are the updated pore processing graphs: The data spreadsheet: pore-processing-results Supplement (added 6/16/09): Here is the Average Pore Size vs. Porosity graph with the outlying data points labeled: After making this graph, I looked at the outliers to see if they were due to my errors. A few were and I redid them, updating the…

The below figure has three different sieving curves. Solid lines are model calculations assuming a SiN membrane with 37 nm pores, and either 0.4, 1.3, or 5 PSI applied to drive the separation. Markers are real data. Note that the experimental data reflects the pressure-dependence of the curve, but is slightly different in concavity from…

Here is a PDF of the presentation I plan to give at BMES this year. The presentation is first an overview of our SiO2 membranes for cell barrier and co-culture models and then a brief summary of our cell-substrate and cell-cell interactions on porous and soft substrates. I am currently working on getting it under…

Charles developed a new microEO chamber, and I did some quick particle tracking experiments.  The fluid in front of the membrane was filled with 200nm fluorescent polymer beads, and the power supply was used to cause the fluid to flow within the chamber.  Bead speed was measured with Henry’s particle tracking programs. Picture of microEO:…
