A Demonstration to Segue Between d to d and CT Transitions

Submitted by Marion Cass / Carleton College on Mon, 08/10/2015 - 19:21
Description

The following is a simple in-class “demonstration” that I use to segue between d to d and charge transfer transitions.  After teaching about d to d transitions and Tanabe-Sugano Diagrams, I show my students three solutions that I have put in large test tubes before class. The three solutions I place in the test tubes are:

a.  10 ml of 0.1M Co(H2O)62+

b.  10 ml of 0.1M Cu(H2O)62+

c.  10 ml of a freshly prepared 0.1 M KMnO4 solution

Peer Review - How does it work?: A literature discussion with a focus on scientific communication

Submitted by Mike Norris / University of Richmond on Thu, 07/02/2015 - 20:21
Description

This learning object is based on discussion of the literature, but it follows a paper through the peer review process.  Students first read the original submitted draft of a paper to ChemComm that looks at photochemical reduction of methyl viologen using CdSe quantum dots.  There are several important themes relating to solar energy storage and the techniques discussed, UV/vis, SEM, TEM, electrochemistry, and catalysis, can be used for students in inorganic chemistry.

Teaching and Learning Package Library from University of Cambridge

Submitted by Vanessa / Albion College on Mon, 06/29/2015 - 15:56
Description

This is a resource that has short, animated tutorials on a variety of different topics. Most of the topics are materials science and/or engineering topics but there are several that would be of interest to chemistry students. (A full list of topics is given below.)

Web Resources from the 2013 Inorganic Curriculum Survey

Submitted by Barbara Reisner / James Madison University on Wed, 06/10/2015 - 10:49

 

In the 2013 Inorganic Curriculum Survey, respondents were asked about the resources they used when they teach inorganic chemistry. About 20% of respondents selected "other" and provided information about these resources. A number of people mentioned specific websites. This collection consists of the websites submitted in the survey.

Tanabe Sugano Diagram JAVA Applets

Submitted by Amanda Reig / Ursinus College on Fri, 04/24/2015 - 13:53
Description

A series of JAVA applets of Tanbe-Sugano diagrams were developed by Prof. Robert Lancashire at the University of the West Indies.  These diagrams allow students to determine deltao/B values based on ratios of peak energies without the pain of rulers and drawing lines.  There are also features that allow a person to input values and automatically calculate certain parameters.  You can also quickly find values of delta_o and B for certain complexes via a drop-down menu on some of the pages (e.g. Cr3+ complexes).    

The Color and Electronic Configurations of Prussian Blue

Submitted by EGunn / Simmons College on Mon, 01/05/2015 - 14:47
Description

I used this paper to illustrate several course concepts related to materials structure (crystal lattice structure, coordination number, crystal field theory and orbital splitting, symmetry, electronic spectra, allowed and forbidden transitions). This activity was paired with a laboratory experiment (see related VIPEr objects) in which students synthesized Prussian Blue, and gave students a really in-depth look at what was going on when they mixed those solutions together.

Five Slides about Spectroelectrochemistry (SEC)

Submitted by Kyle Grice / DePaul University on Tue, 09/23/2014 - 11:49
Description

This "Five slides about" is meant to introduce faculty and/or students to Spectroelectrochemistry (SEC), a technique that is used in inorganic chemistry research and other areas. SEC is a powerful tool to examine species that are normally hard to synthesize and isolate due to instability and high reactivity. Papers with examples of SEC techniques are provided on the last slide. 

 

Fe2GeS4 Nanocrystals for Photovoltaics

Submitted by Anne Bentley / Lewis & Clark College on Mon, 09/15/2014 - 14:00
Description

I asked the students in my junior/senior inorganic course to develop their own literature discussion learning objects and lead the rest of the class in a discussion of their article.  Student Johann Maradiaga chose this article describing the synthesis and characterization of Fe2GeS4 nanocrystals with potential applications in photovoltaic devices (Sarah J. Fredrick and Amy L. Prieto, “Solution Synthesis and Reactivity of Colloidal Fe2GeS4: A Potential Candidate for Earth Abundant, Nanostructured Photovoltaics” J. Am. Chem.
