Exploring Post-Translational Modification with DFT

Submitted by Gerard Rowe / University of South Carolina Aiken on Thu, 07/17/2014 - 12:52
Description

This activity is designed to give students a deeper understanding of what post-translational modification does in a metalloenzyme using nitrile hydratase (NHase) as a model system.  The metallo-active site of NHase contains a cobalt(III) center that is bound to an unusual coodination sphere containing bis-amidate, cysteinate, sulfenate (RSO-), and sulfinate (RSO2-) ligands.

Viewing Jmol Images and Animations (currently blocked) that call a Jmol Applet

Submitted by Marion Cass / Carleton College on Thu, 03/13/2014 - 22:31
Description

 

    Every day when I teach Inorganic Chemistry (and in most of my problem sets and take home exams) I create Web pages to show 3D images of selected molecules to my students.  I am a visual learner and I find the structures beautiful and informative.

    In the past few months, you likely have found that web sites scripted with Jmol scripts calling a Jmol applet (which is a Java applet) are blocked. 

Student choice literature-based take home exam question

Submitted by Hilary Eppley / DePauw University on Fri, 01/24/2014 - 15:27
Description

During my junior/senior level inorganic course, we did several guided literature discussions over the course of the semester where the students read papers and answered a series of questions based on them (some from this site!).  As part of my take home final exam, I gave the students an open choice literature analysis question where they had the chance to integrate topics from the semester into their interpretation of a recent paper of their own choice from Inorganic Chemistry, this time with limited guidance.

Understanding Hypervalency Activity

Submitted by Gerard Rowe / University of South Carolina Aiken on Mon, 11/04/2013 - 10:38
Description

This activity is meant to teach students an MO theory interpretation of hypervalency that goes beyond the simple (and somewhat unsatisfying) explanation that atoms that are in the third row and below use d-orbitals for bonding in addition to s- and p-orbitals. Specifically, students will be learning how to construct MO diagrams for multicenter bonding schemes (i.e., 3c4e).  

IC Top 10 first day activity

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 09/05/2013 - 09:32
Description

I modified the Barb Reisner/Joanne Stewart/Maggie Geselbracht First Day TOC activity (https://www.ionicviper.org/class-activity/introducing-inorganic-chemist…) to take advantage of the quarterly list of Top 10 Most Read articles that IC sends out.  This is delivered to me as an email from ACS pubs and I am sure that it is available to anyone who wished to subscribe to the updates.  I have attached a pdf copy of the August 2013 update as an example.

Five Slides about X-ray Photoelectron Spectroscopy (XPS)

Submitted by Sophia E. Hayes / Washington University on Fri, 06/28/2013 - 09:35
Description

This is a short presentation giving an overview of x-ray photoelectron spectroscopy (XPS), meant to be an introduction for those who are unfamiliar with the technique.

Trends in Measured Redox Potentials and Computed Molecular Orbital Energies of Derivatized Buckminsterfullerenes

Submitted by Robert Q. Topper / Cooper Union on Tue, 06/25/2013 - 01:55
Description

In this project students are asked to reproduce published calculations of molecular orbital energies of a series of derivatized fullerenes and correlate them with published reduction and oxidation potentials obtained from cyclic voltammetry. The particular subset of the derivatives to be studied are chosen by the student and this choice is part of the learning activity. The students then carry out additional calculations using other theoretical models to see whether they improve the correlation between computed and experimental properties.

Lithium Diazenide Surprise!

Submitted by Maggie Geselbracht / Reed College on Fri, 05/31/2013 - 23:00
Description

Students in a sophomore-level inorganic chemistry course were asked to read the paper “High-Pressure Synthesis and Characterization of the Alkali Diazenide Li2N2” (Angew. Chem. Int. Ed. 2012, 51, 1873-1875. DOI: 10.1002/anie.201108252) in preparation for a class discussion.  For many students, this was a first exposure to reading the primary literature. 

So Much Nitrogen: Maggie's Explosive Main Group Compounds

Submitted by W. Stephen McNeil / University of British Columbia Okanagan on Thu, 03/21/2013 - 00:47

Maggie Geselbracht has a great fondness for compounds with too many nitrogen atoms next to each other.  This is a collection of problem sets and class activites based on the structure, bonding, and spectroscopy of a number of such compounds, drawn from the recent literature.

Voices of Inorganic Chemistry

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Sun, 01/27/2013 - 17:08
Description

This learning object focuses on the new video series, “Voices in Inorganic Chemistry,” established to commemorate the 50th anniversary of the American Chemical Society journal, Inorganic Chemistry. The are currently 12 videos celebrating pioneers in the field of inorganic chemistry.  This activity consists of two components, namely the students watching one interview and writing an essay about their chosen inorganic chemist.
