Really proud of this work by Dr. Hyunggu Kim! We show that cation exchange of ZnS magic size clusters with Co(II) results in surface doping at low temp, which isn't a surprise. What was a surprise is that with heating we observe the conversion of surface to bulk-like Co(II). doi.org/10.1021/acs....

I’m teaching a descriptive inorganic chemistry course this semester and found the textbook does a poor job showing the variation of oxidation states for the transition metals. If you feel the same way head over to this great resource from @dvgroupumass.bsky.social. cgt.dvgroup.umasscreate.net. Free!
