As per Chris request, here is a photo with a brief description.
Sorry the image is still not good… the surface of the plastic reflects lights and it is transparent, plus I am using a poor camera. But I hope the description is useful and anyway tomorrow we can check it out in the meeting!
Ag/AgCl electrodes are used overwhelmingly in streaming potential and sometimes in electroosmosis. The benefit of using Ag/AgCl in electroosmosis should be less gas generation and the ability to make an enclosed pump. Here is some information on my attempt at Ag/AgCl EO. .2mm silver wires were coated with AgCl using protocol. Electrodes were immersed in…
Principle of Operation The electrokinetic properties of charged membrane make it possible for conversion between the electrical and mechanical regimes. The electroosmosis is an example of converting from the electrical to mechanical powers. In reverse, exchanging the mechanical energy for electrical energy relies on two electrokinetic phenomena – the streaming potential and current. Consider an…
I took a sample from w304 over to the Krauss Lab and had them try to image it with AFM. Here are a few pictures (for some reason the color scales weren’t included in a couple of them, but they go from 0-dark to 5-light nm): In both images you can surprisingly see the pores….
Today I looked at 3 more wafers: w158 (9/7/07) – some pinholes, overwhelming amount of very fine debris, not cbs as far as I can tellw160 (9/7/07) – some pinholes, debris, no cbsw171 (9/26/07) – many pinholes, lots of debris, no cbs w158 (200x) – small particles Link to updated report.
Samples of pnc-Si, 5.5 mm x 5.5 mm, were functionalized at Adarza and incubated with fluorescein conjugated BSA. Wells were formed in PDMS to hole fluid above the samples. Samples were wetted with PBS then f-BSA, 5 mg/mL, was added. The samples were placed in petri dishes with DI water soaked Kim wipes; the petri…
Last few weeks, I deposited a couples of wafers to test the effect of oxide thickness on pores. In addition to previous data, I deposited another two wafers, one with 1nm top oxide and the other with 100nm top oxide. I summed up all data from the top oxide experiments. The first image is the…
