In this experiment, students will synthesize and characterize a series of Ru(II) p-cymene piano-stool complexes.
In this experiment, students will synthesize and characterize an iron complex followed by completion of two series of catalytic cross-coupling reactions mimicking the methodology utilized by organometallic chemists to balance catalyst efficacy and substrate scope. Initially the complex Fe(acac)3 [acac = acetylacetone] is prepared. Two sets of catalytic reactions are completed: one comparing different iron catalysts (Fe(acac)3, FeCl2, FeCl3) while the other compares substrates (4-chlorotoluene, 4-chlorobenzonitrile, 4-chlorotrifluorotoluene).
In this experiment, students will synthesize and characterize one of three Ag(I) cyanoximate complexes as potential antimicrobial agents for use in dental implants. This experiment combines simple ligand synthesis, metalation and characterization, and a biomedical application. The complexes are both air and light stable.
Leisure activity after days of hard work at the IONiC VIPEr workshop in Seattle, WA.
Participants rented kayaks and paddled around the lake for about 90 minutes.
Pre-requisites: Application of a generous amount of sunscreen.
The original plan was to paddle to Lake Washington, but no directions or map was provided. So given the lack of navigation skills and familiarity with the area it is no surprise that only one kayak made it all the way to lake Washington (Go team FBL & KMH!).
This learning object is based on discussion of the literature, but it follows a paper through the peer review process. Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots. There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.
This literature discussion is meant to give students an understanding of both the key concept-driven and more “meta” information of a literature paper. Students will use Jillian Dempsey’s paper, “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface-adsorbed hydrogen-evolving species,” to investigate paper authorship, how the scientific method is used in research, and how to understand the important findings of a research article.

I do this activity as an introduction to the nature of science. An object (not easily guessable) is put into a paper bag. The job of the class is to figure out what is in the bag. At first, the students are simply shown the bag (sense of sight). Discussion (hypotheses) ensues on what could be in the bag. I then walk around and shake the bag so students can hear what's in it (hearing). This results in more discussion, with some previous ideas being discarded. The bag is then passed around and students can feel (but not open!) the bag and also try to smell it.
This is a learning object focused on discussing application of the scientific method in the chemical literature. This focuses on the paper “Nickel-Iron Oxyhydroxide Oxygen-Evolution Electrocatalysts: The Role of Intentional and Incidental Iron Incorporation” (J. Am. Chem.
Compound Interest is a website that creates infographics for chemistry related events and items. Specific examples of inorganic chemistry infographics include showing how the metal content in colored glass gives the glass its characteristic color, how the lighting of a match works with the conversion of red phosphorus to white phosphorus, and the various colors that transition metals can have in different oxidation states in water, among many other examples.
Class activity:
An introduction to research, both laboratory and scientific literature.
Before Class: Read the essay by Martin Schwartz entitled “The importance of stupidity in scientific research”, Journal of Cell Science, 2008, 1771. http://jcs.biologists.org/content/121/11/1771.full.pdf
