12 Slides About African American Contributions to the Chemical Sciences

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Wed, 07/21/2010 - 23:53
Description

This presentation provides a brief overview of the contributions of five AfricanAmerican chemists, including two inorganic chemists. George Washington Carver is quite often themost celebrated African American chemist (soil chemist), but he is only one individual! There are many other African Americans that have made important and significant contributions to the chemical sciences. The profiles include inorganic chemists, namely, Professor Gregory H. Robinson, University of Georgia and Dr. Novella Bridges, Pacific Northwest National Laboratory (PNNL).

Biological Inorganic Chemistry: Structure & Reactivity edited by Bertini, Gray, Stiefel, and Valentine

Submitted by Betsy Jamieson / Smith College on Tue, 07/20/2010 - 13:10
Description

Biological Inorganic Chemistry:  Structure & Reactivity edited by Bertini, Gray, Stiefel, and Valentine was published by University Science Books (copyright 2007). It is a detailed text divided into 2 parts.  Part A gives "Overviews of Biological Inorganic Chemistry" while Part B goes into more specifics of "Metal Ion Containing Biological Systems."  Several prominent bioinorganic chemists have contributed chapters to the book in their various areas of expertise.  

Medicinal Applications of Organometallic Compounds

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Sat, 07/17/2010 - 14:51
Description
This learning object focuses on concepts of bioorganmetallic chemistry. I use an article published in Chemical and Engineering News (Dagani, R. “The Bio Side of Organometallics,”Chem. Eng. News, 2002, 80(37), pp 23-29) to introduce students to this field. This activity consists of two components, namely writing a two-page summary of the article and using an in-class activity focused on the concepts of geometry, Crystal Field Theory (CFT) and proposing a mechanism for an overall chemical reaction.

Formal NSF Styled Proposal Writing in Preparation for Original Multi-Week Laboratory Projects

Submitted by Lon Porter / Wabash College on Sat, 07/17/2010 - 13:23
Description

The advanced inorganic chemistry course is completed by all chemistry majors at Wabash College during the fall of their senior year. The capstone character of the course provides an excellent opportunity for utilizing an investigator model of laboratory learning. Student teams are responsible for the preparation of a formal, National Science Foundation (NSF) styled proposal stating the goals, context, experimental timetable, safety considerations, and budget for the execution of an original laboratory project.

Synthesis and Molecular Modeling of Sodium Tetrathionate

Submitted by Kim Lance / Ohio Wesleyan University on Sat, 07/17/2010 - 12:01
Description
This experiment is a computational supplement to synthesis of sodium tetrathionate described in "Macroscale Inorganic Chemistry:  A Comprehensive Laboratory Experience".*  Students will synthesize one sulfur oxyanion (tetrathionate), optimize and compute IR spectra for their synthesized product.   In addition, students will predict (using symmetry arguments) and then compute the IR vibrational modes for six additional sulfur oxyanions.  A comparison of theoretical (IR spectra),

Kinetics of Ligand Substitution Reactions of a Pt(II) Complex

Submitted by Scott Cummings / Dominican University on Sat, 07/17/2010 - 11:47
Description
This inorganic lab experiment, focusing on the kinetics of ligand-substitution reactions of a square-planar Pt(II) complex, involves collecting UV-vis absorption data and analyzing the results to determine a rate law to support one of three proposed mechanisms.

Electron Counting

Submitted by Adam Johnson / Harvey Mudd College on Thu, 07/15/2010 - 14:05
Description

I use these two handouts early in my inorganic course to outline how to count electrons and assign ligand types in a metal complex.  I introduce it early so that I can use the terms "X" and "L" in class.  I come back to it and hit it again when I do my unit on organometallics. The "ligands" handout is my interpretation of the MLH Green paper from 1995 (Green, M. L. H., J. Organometal.

Element Jeopardy!

Submitted by Keith Walters / Northern Kentucky University on Thu, 07/15/2010 - 11:44
Description

Like many inorganic faculty (especially those faced with trying to teach "all" of inorganic chemistry in a one-term junior/senior course), I have found it increasingly difficult over the years to include any significant descriptive chemistry content in my course. Moreover, I have a constant interest in trying to convey some of the "story behind the story" in chemistry, which in this area centers on the discovery of the elements. I was mulling this over at an ACS meeting one time and happened to be in an inorganic teaching session where Josh van Houten (St.
