When teaching my advanced bioinorganic chemistry course, I extensively incorporate structures from Protein Data Bank in both my assignments and classroom discussions and mini-lectures.

This is a simple in-class activity that asks students to utilize any of the given available online orbital viewers to help them identify atomic orbital overlap and interactions. 

The associated paper by Lehnert et al. uses DFT to investigate the reaction mechanism whereby a flavodiiron nitric oxide reductase mimic reduces two NO molecules to N₂O. While being a rather long and technical paper, it does include several figures that highlight the reaction profile of the 4-step reaction. This LO is designed to help students learn how to recognize and interpret such diagrams, based on free energy in this case. Furthermore, using a simple form of the Arrhenius equation (eq.

Inorganic chemists often use IR spectroscopy to evaluate bond order of ligands, and as a means of determining the electronic properties of metal fragments.

This activity is designed to relate solid-state structures to the density of materials and then provide a real world example where density is used to design a new method to explore nanotoxicity in human health.  Students can learn how to calculate the density of different materials (gold, cerium oxide, and zinc oxide) using basic principles of solid state chemistry and then compare it to the centrifugation method that was developed to evaluate nanoparticle dose rate and agglomeration in solution.
