While informally chatting with friends in our math department, I realized that I could put together a presentation about how chemists use group theory. I was invited to give the presentation as part of our math department's weekly colloquium series. The talk was to be one hour in length, and my math colleague described their typical format as:
Every day when I teach Inorganic Chemistry (and in most of my problem sets and take home exams) I create Web pages to show 3D images of selected molecules to my students. I am a visual learner and I find the structures beautiful and informative.
In the past few months, you likely have found that web sites scripted with Jmol scripts calling a Jmol applet (which is a Java applet) are blocked.
Students construct computer models of two transition metal complexes, solve their electronic structures, and inspect the resulting d-type molecular orbitals to identify which are non-bonding, sigma* antibonding, or pi* antibonding. After constructing a molecular orbital diagram, they determine which of the two complexes is likely to absorb light at a longer wavelength.
Description: This is an in class activity I use for first year general chemistry students to understand the relationship between quantum numbers and the structure of the atom.
This in-class activity is intended to help visualize the meaning of the subscripts and coefficients in molecular formulas that appear in balanced chemical equations. It has been my experience that students in 2nd semester general chemistry can sometimes still be confused about this fundamental aspect of chemical language. It substitutes edible candy for the atoms in a molecular model kit, thus allowing students to eat the atoms at the end. (My philosophy is that if students are eating, they're probably awake and could be learning!)
These slides walk students through a solid state synthesis with a simple powder XRD analysis. This presentation was made to answer the question “How do I know what came out of the furnace?” for a general chemistry audience, assuming very little XRD knowledge. Specifically this shows using XRD with database searching to determine phase purity through pattern matching.
(This does not cover the fundamentals of XRD, please see related links for that.)
This is a very brief introduction to the origin of color in nanoparticle systems. A link to a video is included in the slides that shows the addition of the reducing agent to the gold precursor solution. The link is also available as a Web Resourse (below).
Cmap Tools is a powerful free program that can be used to create concept maps. The program works on any platform.
Thanks to Kurt Birdwhistell for posting the link to this tool to the forum a while back.
This 5 slides about gives a basic introduction to synchrotron radiation. Information includes how the particles are accelerated, how they travel to the individual instruments, and where synchrotrons in the USA are located.
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.
