In 2011, I was fortunate to have Nicolai Lehnert come and speak to my bioinorganic class on his work modeling the FeB (non heme iron) center in bacterial Nitric Oxide reductase. He suggested this paper to prepare the students for his talk and I developed this reading guide to help them (the students) get more out of the reading.
This learning object was developed with a lot of help from B. Scott Williams from the Keck Science Department of the Claremont Colleges for my junior/senior level course in 2009. This object is a literature discussion on the topic, but Scott and I hope to add a 5-slides about learning object to go with it shortly. The primary literature article used for the discussion is “Characterization of a Rhodium(I) sigma-Methane Complex in Solution,” by Wesley H. Bernskoetter, Cynthia K. Schauer, Karen I.
This paper from Chemistry: A European Journal by Manolis Manos and Mercouri Kanatzidis (link provided below in Web Resources) describes the ion-exchange chemistry of a layered sulfide (KMS-1) that exhibits an enhanced preference for soft metal cations (Cd2+, Pb2+, and Hg2+) replacing K+ in between the metal sulfide layers of KMS-1. Not only does this paper provide a practical application of hard-soft acid-base theory (HSAB), but it provides an accessible introduction to the technical literature for undergraduates, par
This is an in class exercise that I use to introduce structure and magnetism to a junior/senior level course on bioinorganic chemistry. The class is cross-listed between Chemistry and Biochemistry. All of the students have had general chemistry and organic (with some exposure to MO Theory). Many of the students have also had the sophomore-level inorganic course, which delves extensively into MO theory, and some of the the students have also had the senior-level course on transition metal chemistry which looks deeply at d-orbital splitting.
This paper, while not fundamentally groundbreaking, serves as a nice introduction to the field of mesoporous materials. I like that it covers synthesis, characterization, and an application of the materials. I have used this paper in our senior seminar course as the basis for discussion of this area of chemistry. Discussion questions cover aspects of sol-gel chemistry, powder diffraction, gas adsorption, IR, solid state NMR, UV-Vis, and catalysis.
For years, I spent 2-3 days a semester working through Tanabe-Sugano diagrams, their development from terms, their evolution from Orgel diagrams, their analysis to give transition energies (the old ruler- trial and error analysis) and nephalauxetic parameters. Recently, colleagues in VIPEr convinced me that my time in class could be better spent, but I am not willing to completely give up on Tanabe-Sugano.
This is an in class activity to introduce the topic of multinuclear NMR, which is not covered (beyond 13C) in our sophomore level organic course. It is designed to walk the students through the process of predicting NMR spectra, as they learned in sophomore organic chemistry, but for a different I=1/2 nucleus, in this case 19F, which is I=1/2 and 100% abundant.
I just found this neat little web-based tutorial at the University of Alberta. It goes through UV-Vis, IR and NMR. Its coverage of IR is almost exactly what I expect my students to know. In typical "stretch and release" fashion, I teach more, but if my students could do the practice problems on the website, I'd be happy.
The site was put together by Greg Nilsson, Enrico Fok, June Ng and Jason Cooke of the Department of Chemistry.
There are also has some great problems for multinuclear NMR.
The site has a tutorial, practice problems, and live feedback. Way cool!
