I hope to bring this question to our group meeting. As we discussed before, we know that Cl- can be absorbed at the gold surface to screen the applied positive charge. We are using R6G as the filtration species, which…

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…
Since Paul sent an email saying he will be on leave from this week, I spent some time in the hopeman metal workshop with Paul working on our second diffusion chamber before he leaves. We actually failed four substrates before…
Last week Jess and I did some diffusion tests using the prototype chamber. We observed there was some fluorescence background noise from the plastic substrate. So we decided to make the buffer well (the hole on the substrate) all the…
The only problem is the diffusion is very fast with defects in there.
I worked with Paul this afternoon and finally we highly suspect the raw material used for the prototype diffusion chamber could be Polycarbonate. Paul could not provide direct evidence for the material source since he did not keep any purchase…
Attached are the photos taken under DIC and Rhodamine channels, using the new diffusion chamber. I can clearly observe Rhodamine pass to the lower hole of the chamber, under the Rhodamine channel by eye ball. But from what I got…
I have tested the new diffusion chamber shown in a yesterday’s post. The idea of our original design works. But there are several problems with this prototype: – Paul used a very thick material to build the clamp, which blocks…
Our new diffusion chamber is finally here. Take a look at the photos first – in our next group meeting you can see the real thing. Today I will test its usability and reliability. Please keep in mind this is…
Electron Beam Evaporator Protocol (V_1.0) – Lingyun Here is the first version protocol of the electron beam evaporator at RIT clean room. There is not too much to put down here – the best way to learn this is to…
