Week of 1/16-1/22

Most teams have been busy working on their posters for the Annual Meeting. Remember to leave enough tie for printing and to bring your poster with you! Alverno is hoping to conduct a study where they test other teams’ plates with their SEAL kit at the Annual Meeting. If you want to be part of this Interlab study, bring your plates with you to the meeting!

Crescenta Valley tested the two plates from last week (NiCl2, ZnCl2, CoCl2), but had negative results- dark blue for both. They made several more plates, but we haven’t been able to get them annealed yet, so will finish testing them next week. One plate had .1 M BiVO4 with .1 M CoCl2 layered on top; another combined CoCl2, ZnCl2, NiCl2 in differing ratios (Co:Ni 1:1, Ni:Zn 1:1, Co:Zn 1:1), with four spots of Fe(NO3)3 as a standard; last plate had spots combining Ni:Fe:Co in a 1:2:2 ratio.

Mayfield ‘s team RAM made plate 9 (CuW) with the ratio of 10:6 and plate 10 (AlW) 10:6. Team SEA has noticed a trend with their colored & non-colored metal combinations: a higher ratio of non-colored to colored metal seems to produce more active materials. Their most active spot so far was iron tungsten in a 4:7 ratio. 

Franklin’s team “Versace” has posted the combinations of metals used on their first 3 plates. The metals they are testing are BiVO4, Co (II) acetate, Fe (III) nitrate, Ni (III) nitrate, and WO2Cl2. They will be using the HARPOON kit I believe, and after results are posted, I will point out specific ratios that had above average results.

Keep up the great work and see you soon!


  1. Franklin’s team Versace (we love your name): what is the reasoning behind choosing the metals you’re working with?

  2. Cresenta Valley, what is the reasoning behind your metal choices?
