1236 npMgF2 Temp Series structural comparisons to 1085 npMgF2

Here are some high resolution TEM images from a SiMPore-UIUC collaborator. Chris says: The high resolution stuff looks pretty cool, especially the zoom-in on the 8nm pore.  I the most obvious crystal planes are <111> with 0.314 nm spacing.  If you look carefully, some 0.192 nm <110> planes and 0.136 nm <100> planes can also…

As I mentioned in my previous post, there are a lot of problems associated with the technique for testing the ability of a CytoVu assembly to act as an assay that I had been trying to use before. Several possible sources of error were apparent, such as the difficulty inherent in consistently pipetting such small…

At Nanotech I met a professor from Geneseo, K. Yokoyama, who worked with gold in sol-gels. He found he was able to dissolved gold in sodium tetra bromate (Na2Br4O7) without it aggregating. I have attempted to dissolve gold in other salts to no avail. This is an important step in testing membrane separations with gold,…

Now that we have preliminary transport data from the Tecan, we need standard curves in order to get permeability coefficients. This is really tricky because the RFU (relative fluorescent units) are arbitrary and based on the Tecan gain. For example, a solution of 10uM rhodamine might be 5000 RFU with a gain of 80 but…

Kelly & I finally succeeded in getting a measurement of the SU-8 scaffold change in size upon liftoff.  Kelly, lifted off a sample (~0.5 x 2 cm) using the XeF2 dry etch and transferred the sample to a glass slide with pdms bonded to it. The slide was then placed on top of the printed…
