This is a short presentation giving an overview of x-ray photoelectron spectroscopy (XPS), meant to be an introduction for those who are unfamiliar with the technique.
This literature discussion is based off a Nature article by Buck, Bondi, and Schaak (Buck, M.; Bondi, J.; Schaak, R. Nat Chem 2012, 4, (1), 37-44 DOI: 10.1038/NCHEM.1195). It spans topics of solid state, crystallography, characterization techniques, and comparing inorganic to organic synthesis.
This in-class activity was created at the NSF-TUES sponsored workshop at Penn State, June 2013. It is based on the article from Ray Schaak’s group (Buck, Matthew R.; Bondi, James F.; Schaak, Raymond E. “A total-synthesis framework for the construction of high-order colloidal hybrid nanoparticles” Nature Chemistry 2012, 4, 37-44, DOI: 10.1038/NCHEM.1195), which Ray presented at the workshop.
This presentation provides a short introduction to Quantitative Structure-Activity Relationships and its use in Inorganic Chemistry. A brief introduction to Linear-Free Energy Relationships and the Hammett Equation is given, followed by three examples of how QSARs have been used in inorganic chemistry.
This literature discussion activity is designed to highlight the use of different instrumentation and what details can be gained from each instrument. It should also help the students review their knowledge of crystal structure, types of crystals, and amorphous solids. The paper is from Chemistry of Materials, 2013, 25, 2394-2403 (DOI: 10.1021/cm303490y). The paper should be given one week prior to class discussion, ideally after covering some of the instrumentation in class including X-ray dif

This Literature Discussion learning object (LO) is based on the paper “Template Electrodeposition of Single-Phase p- and n-Type Copper Indium Diselenide (CuInSe2) Nanowire Arrays,” Emil A. Hernández-Pagán, Wei Wang, and Thomas E. Mallouk, ACS Nano, 2011, 5 (4), pp 3237–3241. DOI: 10.1021/nn200373k
The paper from the Prieto group, Riha, S. C.; Parkinson, B. A.; Prieto, A. L. J. Am. Chem. Soc. 2011, 133, 15272-15275, is proposed to be an excellent literature article for achieving several learning goals in the understanding of fundamental solid state and materials chemistry. The learning object was developed as a part of the 2013 VIPEr workshop and has not been tested in the classroom. We have developed a set of discussion questions that can be used as a guide for the students.
Concept maps are a visual way to organize and represent information. In this literature discussion, we introduce a novel technique for teaching literature analysis to students where concept maps are used for establishing relationships between the key ideas, theories, procedures, and methods of a proposed literature article. Using the article “Compositionally Tunable Cu2ZnSn(S1-xSex)4 Nanocrystals: Probing the Effect of Se-Inclusion in Mixed Chalcogenide Thin Films” (Riha, S.C.; Parkinson, B.A.; Prieto, A.L. J. Am. Chem.
Students work individually, then compete in teams, to identify symmetry elements and operations present in a high-symmetry structure, such as an octahedron or tetrahedron (without showing the character table until the end of the activity). Students often visualize symmetry elements differently from one another. Creating teams, allows them to work collaboratively, and the competition adds an incentive for finding the most elements. Since some students are better at seeing some symmetry elements (and operations) than others, it allows for them to work in small groups to both teach and lea
