Here are some other in-situ heating videos I made recently. First one is NSN30730, which means the Si is 7nm and Si3N4 is 30nm. The speed of the video is 10 time faster than the real time. The first figure…

This is a follow up to my previous post, “Burst Pressure Probability II”. I burst 111, 30nm thick single window pnc-SI TEM chips of ten different window sizes, to measure the burst pressure of chips with varying dimensions. Although area is a…

Sarah, Tejas, and I bought some “Invitrogen Ultrapure DI water” from the medical center to see if we would find a different permeability using the clean water vs the water from the Barnstead. Sarah and I repeated our permeability tests…

Hi all, Previously we described a two-compartment flow system integrated with a nanoporous membrane in between; and we showed that the nanporous membrane effectively reduces fluid flow from one compartment to the next. Seeing that today is our last NRG…

I’ve been working on building a streaming potential/EO device for a while now. This was Yaron’s prototype: Which itself was based on Jess’s design: I didn’t like that the device needed to twist together, and also that it was designed for…

Here is an interesting discovery of nanopores in the SiO2 layer after the laser annealing. Basically I was doing laser annealing on free-standing OS membrane the other day. It’s an excimer laser  with 248nm wavelength, 25ns FWHM and spot size…

Sarah and I did some more gold separations with 10, 20, 40, 50, 60, 80 and 100 nm Au particles.  We used the “clean” water purchased from the medical center.  Same as last time, we diluted the “as-bought” gold 3…

Our work with permeance and hydraulic permeability tests on the SiN-NP seemed to show that the porosity and pore sizes I had calculated from the STEM images were too high.  I used URnano’s TEM to get better quality images and,…

I found another old wafer # 760 and asked Josh Miller to deposit a 25-50-25 OSO stack.  He did a standard RTP of 1050 C, 60 s, 100 C/s.  (and Josh Miller did the EDP etch, so this is really…

Since the basic protein diffusion experiments went well, I’m moving up to something that more closely resembles an actual assay application. The basic idea is this: Biotin-conjugate FLAG antibody will be bound to Avidin acrylic beads in order to make…
