Happy to share this publication that was part of the thesis work of Dr Gaurav Mitra. Another example of colloidal nanocrystals not adopting the same dopant speciation(s) as their bulk analogue! pubs.acs.org/doi/10.1021/...
I am also searching for a postdoc to work on this project! For more information and to apply, please check out the job listing at WSU jobs, wsu.wd5.myworkdayjobs.com/en-US/WSU_Jo.... My contact information is included in the job listing.
graphical abstract showing the redshifting excitonic-like transition of ZnS magic size clusters and concomitant changes in the Co2+ ligand field transitions from surface speciation to internal speciation similar with increasing growth temperature temperature. The ligand field transitions of the internalized Co2+ are similar to the transitions of Co2+ in ZnS single crystals.
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 was trained in grad school to use “electronic absorption” and I’ve been using it ever since (also doesn’t require defining the abbreviation). What happens if you also have a near-IR transition? UV-Vis-NIR?
I read it as no new awards in FY26, but they are still obligated to funds FY24/25 awardees.
This database was created by an undergrad that wrote a python script to search the Cambridge Structural Database. There is a J. Chem. Ed. article associated with the database for additional information. Link at the DV group website.
Pie charts for the different transition metals where different colors correspond to different oxidation states. The size of the slice is proportional to the number of reported crystal structures with the given oxidation state.
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!
