Hi all,
Tomorrow Danny will speak at group meeting - see below for his title and
abstract. Part of it will be practice for a talk at ACS next week.
Otherwise, we're a little short on group meeting speakers - if you have a
talk you'd like to give, or have someone visiting (whether Toronto- or
Boston-side), please let me know :)
All the best,
Ian

Title: Status and Challenges of Organic Aqueous Redox Flow Battery
Development
Abstract: I will cover the challenges and developments of our group's
collaboration with Mike Aziz and Roy Gordon on organic redox flow
batteries. First I will tell the story about the initial promise of
2-5-dihydroxy benzoquinone (DHBQ). Then, there will be a riveting tale
about how (slightly-altered) proposed substitutions on DHBQ initially meant
to suppress semi-quinone formation were transferred over to anthraquinones
to create 4,4′-((9,10-anthraquinone-2,6-diyl)dioxy)dibutyrate (known as 2-6
DBEAQ), which the group has branded "Methuselah." The twist is that primary
the reason it is the most stable organic alkaline flow battery molecule is
not what we initially thought and this is leading to an interesting
follow-up study. I will then discuss our group's recent efforts to take a
second look at phenazines and fused phenazines, motivated by a recent study
published by PNNL. Finally, I will discuss a machine learning approach to
explore restricted regions of chemical space to discover new flow battery
electrolytes, which is the subject for my ACS talk next week.
