Collin Muniz wins poster competition at AIChE student conference

This year’s American Institute of Chemical Engineers (AIChE) Student Conference was held in San Francisco last month. One of the conference highlights was the undergraduate poster competition. 
 
Collin Muniz, a CSMC collaborator from May Nyman’s lab, was one of just a handful of chemistry majors among the engineers presenting posters; an estimated 400 students were entered into the competition. 
 
Collin’s poster was titled Synthesis, Structural Characterization, and Luminescence Studies on an Unreported Series of Oxalate Linked Heterometallic Coordination Polymers. He won first place in Materials Engineering and Sciences VII, and he is the only Oregon State University student who placed in the competition. 
 
You can view the abstract below, as well as the PDF of the winning poster. 
 
Congratulations, Collin! 

ABSTRACT

A previously unreported series of heterometallic, rare earth-niobate coordination polymers of the formula [LnNbO(C2O4)3(DMSO)Ln = (Y, La, Ce, Nd, Sm, Eu, Gd) ] have been synthesized via a feasible treatment of Ln(NO3)3•5H2O, NH4NbO(C2O4)2 •X H2O, and oxalic acid in DMSO solvent. A single crystal of the La analogue was obtained, and the structure was solved via single crystal x-ray diffraction. Rietveld refinement techniques were performed on the remaining lanthanide analogues to understand structural variation as a function of ionic radius. The structure consists of LnO9 and NbO7 polyhedra bridged by oxalate ligands to form an anhydrous coordination polymer. Luminescence studies evinced characteristic rare earth emission, and high Eu3+ quantum yield of 66% was observed due to an anhydrous crystal lattice.
