Wafer 415-T has been delivered to the lab. It was processed with TEOS and annealed at 950 C. There are a few usable samples, especially along the edge of the wafer. Pinhole density increases as you move towards the center. The uniformity across the wafer is good. From left to right, top to bottom: (0,1)…
One of the markers of endothelial monolayer maturation/barrier function is the expression of adherens junction and tight junction proteins. The adherens junction is composed of transmembrane proteins called cadherins (among other proteins) that link cadherins of neighboring cells to the actin cytoskeleton. They are found in most (all?) vertebrates and are necessary for cell-cell adhesion…
Hi all, recently we improved cell tracking with the use of SiR-DNA label (see highlights below). random migration: A. Representative cell tracking from three independent migration experiments, color-coded by the color bars to the left in red, green, and blue. B. Distributions of motility parameters (persistence time, instantaneous speed, average speed, pathlength, and displacement)…
Hello everyone! After a long time waiting and setting up, the new AJA and RTP at Vanderbilt University now are ready to go! Here are a couple of pictures of the new AJA and RTP. I have been working on testing the new AJA for a while with my old recipes. The new AJA system…
In April of last year, I spent a considerable amount of time trying to visualize protein separations using SDS-PAGE (Sodium Dodecyl Sulfate-PolyAcrylamide Gel Electrophoresis) gels, and ultimately was able to get some data: I was trying to show that 15 nm pnc-Si could be used to separate BSA from cytochrome c, and while at first…
One of the things that I’ve been working on recently is trying to explain the extreme elasticity of the pnc-Si material which is connected to its nanocrystalline structure. There are two parts in this question. First, how are amorphous or crystalline phases involved during stretching? Second, does the crystalline phase change under application of mechanical…
