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.

Identifying Organometallic Reaction Classes in Literature Examples of Catalytic Cycles

Submitted by Nicole Crowder / University of Mary Washington on Thu, 07/19/2012 - 14:05
Description

This learning object has the student search the chemical literature for a paper focusing on a catalytic cycle (Wilkinson’s, Grubbs, Heck, Wacker, Suzuki, Click, etc.). They answer a set of guiding questions for reading the literature, then analyze the catalytic cycle presented in the paper to assign oxidation state, d electron count, valence electron count, and preferred geometry for each complex in the cycle. They also identify the process(es) occurring during each step in the cycle.

Exploring the Nanoworld Innovating through Materials from the University of Wisconsin Madison

Submitted by Patricia Stan / Taylor University on Thu, 07/19/2012 - 13:29
Description

This is a great web resource for all types of nano materials.  There are lesson plans, demos, activites, labs and lots of background information.  It is very easy to navigate and there are videos of the labs so you can see each step - very useful when doing a type of synthesis or technique new to you.

Writing assignment series related to topics discussed in organometallic chemistry - Assignment 3 Literature Critique

Submitted by Abby O'Connor / The College of New Jersey on Thu, 07/19/2012 - 11:31
Description

Searching and reading the literature is an important tool in teaching organometallic chemistry. This overall project focuses on the improving students' writing skills and to begin to think critically about articles in the literature through a series of different writing assignments. This project is used in a semester long course on organometallics and reaction mechanisms. The first assignment (this LO) is a summary, the second is related to the NSF highlight, and the third is a literature critique.

An Introduction to Electrocatalysis: Hydrogen Evolution from Mono and Binuclear Cobalt Complexes

Submitted by Abby O'Connor / The College of New Jersey on Thu, 07/19/2012 - 10:45
Description

This learning object was developed at the 2012 NSF sponsored cCWCS VIPEr workshop at UNC-CH where we were fortunate to hear Jillian Dempsey present this research that has appeal to students. This work focuses on an exciting and promising strategy to develop new technology to support a solar energy economy. This literature discussion leads students through a current application in the field of electrocatalysis.

Literature Discussion on “Mechanisms for the Activation of Carbon Monoxide via Oxorhenium Complexes.”

Submitted by Nicole Crowder / University of Mary Washington on Thu, 07/19/2012 - 09:54
Description

This is intended as a guided reading assignment for the JACS Communication, Mechanism for the Activation of Carbon Monoxide via Oxorhenium Complexes” by Smeltz, Boyle, and Ison; J. Am. Chem. Soc. 2011, 133, 13288-13291. This article will expose students to newly published research and novel reaction mechanisms. It will require students to apply their knowledge of electron counting and organometallic mechanisms.

Deciphering Mechanisms of Organometallic Reactions

Submitted by Nicole Crowder / University of Mary Washington on Thu, 07/19/2012 - 09:42
Description

A detailed in-class analysis of the paper Mechanism for the Activation of Carbon Monoxide via Oxorhenium Complexes” by Smeltz, Boyle, and Ison; J. Am. Chem. Soc. 2011, 133, 13288-13291.  Students will apply their knowledge of organometallic chemistry concepts to the mechanistic scheme in the paper.
