Academic Activities

8th February - 16th February, 2016

• Presented my work to the "Programmable self-assembly subgroup" on the 11th of February. Metin attended that presentation. The group expressed interest in one of the results presented in "A geometrical approach to the incompatible substructure problem in parallel self-assembly". The wanted to know why the 90 deg component experiments resulted in a high yield. I told the group that we suspect that symmetry and the high probability of forming pairs could be the reason for the high yield. I added that we would be studying this phenomenon in detail using video tracking in our upcoming work on the extended yield prediction paper. The group also had some input for the issues I have with regard to the conformational switching work.
• Increased the shielding of conformational switching components. The increased shielding seems to reduce the local effects of magnets in the vicinity.
• Finished designing the jig that we will use to create "random kicks" during orbital shaking. I will be meeting the in-house production engineer this afternoon before getting it fabricated.
• The shaker has not yet arrived. The secretary here (Janina) says we would have to wait for a few more weeks.
