An aluminum complex of a tripodal tris-(nitroxide)-based ligand has been prepared and characterized. The complex has the ability to participate in metal−ligand cooperative catalysis, which has been exploited for the hydroboration of both aldehydes and ketones. This represents new, transition-metal-like reactivity for an earth-abundant metal.
N-oxides can amplify the performance of a lanthanum aminobisphenolate catalyst in the ring-opening polymerization (ROP) of rac-β-butyrolactone (rac-BBL) to unprecedented levels (TOF / Pm ; At RT: 1,900 h-1 /...
The ability to communicate scientific
concepts to expert and nonexpert
audiences is an essential skill for chemistry and STEM students. Current
chemistry curricula mainly focus on developing skills to communicate
technical information to expert audiences, while relaying the same
information to general audiences receives much less attention. Although
numerous initiatives work to close this gap, many have logistical
or financial barriers that make them difficult to integrate in a large
classroom setting. Herein, we present an assignment focused on improving
advanced students’ (i.e., graduate and advanced undergraduate
students) ability to communicate current organometallic chemistry
research (i.e., technical information) to a general audience using
infographics. Our assignment features a unique, iterative feedback
model incorporating instructor, peer, and near-peer (general audience)
groups to provide students with multiple opportunities to refine their
communication skills. Anonymous student self-assessments of advanced
undergraduate/graduate students (infographic creators and peer reviewers)
and first year, non-major undergraduate students (near-peer reviewers
and general audience) indicate that the assignment led to (i) increased
confidence in communication skills (advanced undergraduate/graduate
students), (ii) a broadened understanding of advanced chemistry in
everyday life (both), and (iii) increased recognition for the importance
of scientific communication to different audiences (both). Reflections
on student outcomes as well as recommendations and considerations
for instructors are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
