Five Slides About Magnetic Susceptibility

Submitted by Sibrina Collins / Marburger STEM Center (MSC) at Lawrence Technological University on Tue, 07/29/2014 - 12:38
Description

This Five Slides About provides an overview of the concept of magnetic susceptibility for paramagnetic metal centers. Three methods are discussed, namely the Evans NMR Method, the magnetic balance and SQUID (Superconducting QUantum Interference Device). The availability of each method varies across institutions.

Introduction to Photoinduced Electron Transfer

Submitted by Robert Holbrook / Northwestern University on Thu, 07/17/2014 - 17:37
Description

This 5 slides about will introduce students to the concept of photoinduced electron transfer. These slides go over the energics of photoinduced electron transfer, which implements basic concepts of photochemistry and electrochemistry. The photoinduced electron transer properties of ris-(2,2'-bipyridine)-ruthenium(II) is used as an example. 

Databases for Kinetics

Submitted by Adam Johnson / Harvey Mudd College on Mon, 06/03/2013 - 15:02
Description

I recently came across some web resources for teaching kinetics. They are searchable compilations of kinetics data, principally gas-phase. Two of the sites include "recommended" data for use in simulations.

I describe the four sites here and the URLs are here and below.

This is a critical tabulation of the latest kinetic and photochemical data for use by modelers in computer simulations of atmospheric chemistry

C(sp3)-F Activation through an Initial C(sp3)-H Activation Mechanism

Submitted by John Lee / University of Tennessee Chattanooga on Wed, 07/18/2012 - 16:35
Description

This paper is from a Science article from Alan Goldman’s group at Rutgers University. It was one of the literature articles that was assigned during the IONiC VIPEr Workshop in July 2012.  In conjunction with reading the article, workshop participants attended a seminar presented by Alan Goldman on this work.

Effects of defects on the properties of single-walled carbon nanotubes

Submitted by Sherri Lovelace-Cameron / Youngstown State University on Mon, 07/16/2012 - 21:49
Description

I teach advanced inorganic chemistry and wanted to find ways to bring in the primary literature, applications, and current research areas.  Students read the article, "Role of Defects in Single-Walled Carbon Nanotube Chemical Sensors" by Eric S. Snow, Nanoletters 2006, 6 (8) pp.

Application of Organometallic Chemistry – Breaking the Inert C-H Bond

Submitted by John Lee / University of Tennessee Chattanooga on Mon, 07/16/2012 - 11:39
Description

This learning object is a literature discussion based on a paper published in Nature (Labinger, J. A.; Bercaw, J. E. Nature 2002, 417, 507-514; doi:10.1038/446391a) discussing the mechanisms of C-H activation by transition metal complexes. This is a topic that could be covered at the end of a section on organometallic chemistry that shows a “newer” application.

Solubility and the Need for Bioinorganic Metal Ion Transport and Storage

Submitted by Sheila Smith / University of Michigan- Dearborn on Mon, 07/16/2012 - 09:42
Description

 

This is an in class exercise that I use to emphasize the need for metal ion transport and storage in biochemistry.  Applying the Van't Hoff equation to the Ksp value at 25°C for ferric hydroxide, students calculate the iron concentration at which ferric hydroxide would begin to precipitate out in the blood.  It' s an interesting problem that requires very little math beyond that used in gen chem, and the answer is in stark contrast to the amount of iron that we actually store in our bodies.  

The Eyring Equation

Submitted by Adam Johnson / Harvey Mudd College on Thu, 09/29/2011 - 01:46
Description

I was taught (many years ago) the common misconception that fitting the linearized form of the Eyring equation overstates the error in the intercept because on a 1/T axis, the intercept is at infinite temperature, and the intercept is far from the real data. While researching various methods of data fitting, I stumbled across this great article from the New Journal of Chemistry (New J.

Literature Discussion: "Analysis of an Unprecedented Mechanism for the Catalytic Hydrosilylation of Carbonyl Compounds"

Submitted by Lori Watson / Earlham College on Sun, 03/09/2008 - 16:14
Description

This is a literature discussion assignment in which students read a paper, come up with their own answers to the provided questions (and submit them).  This is followed by a general in-class discussion on the paper.  This particular article deals with hydrosilyation of carbonyl compounds by a Re catalyst and describes the mechanism and kinetics in detail.  I found it a good paper to help students connect their P-chem (and inorganic) kinetics with a "real" system.  As part of the literature assignment, I also ask students to draw an MO diagram of a simple substrate (for review).
