Analyzing a journal article for non-content issues of style and convention

Submitted by Sarah K. St. Angelo / Dickinson College on Mon, 07/30/2012 - 15:59
Description

This is an in-class activity--or an activity students do prior to class to in preparation for an in-class discussion--to help students identify stylistic components of published writing.  I provide the students with an appropriate journal article, typically a communication from Inorganic Chemistry, such as Inorg. Chem. 2008, 47, 2922-2924 (http://pubs.acs.org/doi/pdfplus/10.1021/ic702373b) or Inorg. Chem.

Exploration of Nitrosyl Complexes

Submitted by Brad Kraft / St. John Fisher College on Mon, 07/30/2012 - 15:33
Description

This in-class activity and the related problem set allows students to discover the linear and bent bonding modes of NO to metals based on VSEPR theory through guided inquiry.  Two examples follow which illustrate how the electrons are counted in NO complexes depending on the coordination mode/formal charge of NO. Students must have had prior practice in counting electrons of complexes to complete the problems.

Soluble Methane Monooxgenase Spectroscopy

Submitted by Gerard Rowe / University of South Carolina Aiken on Fri, 07/20/2012 - 09:37
Description

Determining the reactive intermediates in metalloenzymes is a very involved task, and requires drawing from many different spectroscopies and physical methods.  The facile activation and oxidation of methane to produce methanol is one of the "holy grails" of inorganic chemistry.  Strategies exist within materials science and organometallic chemistry to activate methane, but using the enzyme methane monooxygenase, nature is able to carry out this difficult reaction at ambient temperatures and pressures (and in water, too!).

Dioxygen Activation in Non-heme Iron Enzymes

Submitted by Gerard Rowe / University of South Carolina Aiken on Fri, 07/20/2012 - 09:26
Description

This lecture provides a short introduction to the other half of biological iron chemistry:  enzymes that do not contain a porphyrin group that ligates the iron atom.  There are several important applications for non-heme iron in cells, both mammalian and bacterial.  Oxygen activating non-heme iron enzymes fall into a few basic categories and includes mononuclear iron monooxygenases and dioxygenases, and binuclear iron monooxygenases. The requirements to activate and utilize dioxygen will be given.

Electrocatalysis and Proton Reduction

Submitted by Matt Whited / Carleton College on Thu, 07/19/2012 - 16:46
Description

These slides provide a brief introduction to the concept of electrocatalysis using the glyoximato cobalt catalysts for hydrogen production recently examined by Peters, Gray, and others.  They provide a suitable introduction to the topic for students interested in reading the primary literature on these topics.

Home Built Equipment Links

Submitted by Chris Bradley / Mount St. Mary's University on Thu, 07/19/2012 - 15:09
Description

I am always interested in building/modifying equipment and glassware, and the following C and E News article led me to an interesting website, also linked, where details on building homemade rotators and stir plates are in place. Both models can be constructed with materials for less than $30. As I'm always looking to keep costs down for equipment like this, I thought I would share it. If anyone knows of other links, please let me know.  

 

 

Computational Chemistry for Chemistry Educators

Submitted by Marites (Tess) Guinoo / University of St. Thomas on Thu, 07/19/2012 - 14:29
Description

I learned of this website after attending the Computational Chemistry for Chemistry Educators (CCCE) workshop last summer '11. In this webpage you will find all the workshop lectures intended for audiences who do not have a computational expertise. You will also find lab exercises already written.

Catalysis: Copper-Mediated Cross Coupling Reactions

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Thu, 07/19/2012 - 14:29
Description

This in-class activity introduces students to copper-mediated cross coupling reactions. In the literature, many cross coupling reactions are often discussed using palladium as a catalyst, not copper. In my laboratory, we are synthesizing 7-azaindole-based ligands for the development of potential anti-tumor platinum(II) complexes. In addition, I use one of my own publications to demonstrate an application of this synthetic strategy. The students calculate the actual turnover number (TON) and turnover frequency (TOF) for the copper catalyst.
