Day 5: 5/26

 Last night, I had a call with John about some of the next steps. 

Main things were:

• Since the evaporator was not working/needs fixing, Xiaobing will email the lab director and have the evaporator fixed.
• Need to 3d print the razor holder
• Need to design a 3d holder for the cylindrical rods
• This needs to also have some sort of place for weights on top
• This also needs to be able to have some sort of balancing mechanism
• Talk with Thomas and David about what exactly they want to do with the graphene
• John wants to make ITO more conductive
• One way is by making scribing more efficient
• The other is by using a ink that loses 5% but is very very conductive
• I need to ask Sandy/Felix:
• How to get a bunch of perovskite plates coated to try scratching
• How to do "wet" scratching later
• Talk to Felix about Slot Die specific measurements

I also need to find screws for the robot holder

After eating lunch, I 3D printed the holder for the robot, and talked with Xiaobing about the perovskites he made. I learned that Yunfei will probably learn more about the slot die tomorrow, and I'll watch Xiaobing make perovskites tomorrow also.

I then went to the machine shop and found out that it was closing, but took measurements of the razor, the screws, and will go there tomorrow morning.
