The article from The Journal of the American Chemical Society by M. Kanatzidis et al describes a new ion-exchange material (FJSM-SnS) that shows high selectivity for rare-earth metals (REE) and very fast adsorption kinetics. A number of techniques are used to characterize the properties of the compound that students may not be very familiar with but the article presents in an accessible way.
I created this activity as a way to get the class involved in creating new, fun ways to teach course concepts (selfishly- that part is for me) and for students to review concepts prior to the final exam (for them). Students use a template to create a 15-20 min activity that can be used in groups during class to teach a concept we have learned during the semester. We then randomly assign the activities and students work in groups to complete them and provide feedback.
The benefits are twofold:
In an attempt to find a substitute for our chemistry seminar program, I have found a number of YouTube videos of chemists giving seminar lectures, mostly between 2017-2020. The topics span a range of chemistry disciplines, and are all around 1 hour in length (typical seminar length). I have not watched them, so I cannot vouch for video quality. Feel free to add additional links in the comments below if you know of or find any great talks.
We will ask students to select and watch a certain number of lectures from the list and then write and submit a one-page summary of the talk.
This tutorial will introduce students to some of the three-dimensional crystal structures exhibited by ionic and metallic solids. They will examine the simple cubic, body-centered cubic, face-centered cubic, and the hexagonal closest-packed systems. To facilitate visualization of the structures at the atomic level, they will use the Crystal Explorer website at Purdue University.
This first-year laboratory is designed to give students an introduction to basic solid-state structures using both CrystalMaker files and physical models. I think this would work in a foundations level inorganic course as well. It could be used alternatively as an in-class activity or take-home problem set depending on the instructor. It was adapted by me and later, David Harvey, from an original activity that was posted as an educational resource on the CrystalMaker website in the mid 2000s.
Congratulations to the 2019 recipients of the Nobel Prize - John B. Goodenough, M. Stan Whittingham and Akira Yoshino. It's a well deserved honor!
There are several LOs on VIPEr that talk about lithium ion batteries and related systems. The 2019 Nobel is a great opportunity to include something about these batteries in your class.
I hope to see more LOs in the coming weeks so we can bring this chemistry into our classrooms!
This is a 1 Figure lit discussion (1FLO) based on a Figure from a 2015 JACS article on synthesizing conductive MOFs. This LO introduces students to Metal-Organic Frameworks and focuses on characterization techniques and spectroscopy.
This literature discussion explores the physical structures, electronic structures, and spectroscopic characterization of several porphyrin-based metal-organic frameworks through discussion of “Iron and Porphyrin Metal−Organic Frameworks: Insight into Structural Diversity, Stability, and Porosity,” Fateeva et al. Cryst. Growth Des. 2015, 15, 1819-1826, http://dx.doi.org/doi:10.1021/cg501855k.
This site is another excellent resource from Dean Johnston (see also his Symmetry resource). It uses JSmol (in a web browser) to display different types of "Packing" and "Point Groups". For Packing, users can select different sizes for the atoms, display multiple unit cells, and rotate the model on the screen. Different layers can be color highlighted.
Other portions of the website include resources for incorporating crystallography into the undergraduate curriculum.
During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.
