On Wednesday, Dr Crider visited my lab. It was a really great feeling to talk about the experiments I had performed and what I had learned. Afterwards, Qin and I ran 4 fuel cells, all with different combinations of substances for the anode and cathode (using carbon nanotubes which had been suspended in a solution of their enzymes, then using a platinum suspension instead of laccase enzyme, then a cathode using suspended GOx and an anode using platinum, then compressed GOx with a platinum anode) but nothing lasted more than an hour which was extremely frustrating.
Finally, on Thursday, we tried out mechanically compressing the powdered forms of laccase and GOx enzyme onto our carbon nanotubes (surrounded by a carbon sheet to sandwich effectively/ for protection of the CNT) and it worked great! We were able to get an all-time high of 163.04 uW for our power density (an all time high for our lab) and it lasted 5 days (another record for our lab). We are extremely happy with these results, but of course we are always looking for ways to make it even better. Hopefully this can be achieved in my last 2 weeks at this lab!
I'm hoping to see some broken records in these next two weeks, but if not, I am still so happy that I've been able to participate in this process and feel like I've made an impact.
Have a great week everyone!
