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. 

 

Learning from UCLA

Submitted by Sheri Lense / University of Wisconsin Oshkosh on Sat, 09/20/2014 - 19:47
Description

This learning object is designed to spark discussion and educate students taking an inorganic chemistry course about laboratory safety.  It uses the article "Learning from UCLA" by Jyllian N. Kemsley (Chemical & Engineering News (2009), Vol. 87 Issue 31, pp.

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.

Trap-to-Trap Distillation of Volatile Organic Liquids (Polyhalomethanes)

Submitted by Craig M. Davis / Xavier University on Thu, 09/04/2014 - 12:45
Description

This lab exercise uses air-stable compounds (polyhalomethanes) to demonstrate trap-to-trap distillation, a technique used to separate air-sensitive compounds. The apparatus (including part numbers from CHEMGLASS) is described. In addition, slush baths are employed, which are a novelty for our Inorganic Laboratory course and a source of amazement for the students. The separation of the compounds (the percentage each compound in each trap) is determined by 1H NMR.

Ligand Lineup

Submitted by Sheri Lense / University of Wisconsin Oshkosh on Fri, 08/22/2014 - 11:40
Description

This is a kinesthetic activity in which students must utilize knowledge of the σ-donating, π-donating and π-accepting ability of ligands in order to rank the ligands in the spectrochemical series.  Students are each assigned a ligand on a card.  Suggested ligands are I-, Br-, Cl-, F-, ONO-, NO2- OH-, H2O, pyridine, NH3, ethylenediamine, bipyridine, phenanthroline, PPh3, CN- and CO.  Each student must evaluate the π-accepting, π-donating and σ-donating ability o

Luminescence

Submitted by Vivian / Clemson University, Department of Chemistry on Thu, 08/14/2014 - 22:53
Description

This is a 5-slides on luminescence. It contains introductory and basic description of different examples of luminscence. Since, this is a community of inorganic chemists, only inorganic compounds are discussed as examples.

A Tale of Two Structures

Submitted by Chip Nataro / Lafayette College on Tue, 08/12/2014 - 10:32
Description

In this activity, students will compare and contrast two closely related structures, [Pd(dcpf)PR3]2+ (dcpf = 1,1'-bis(dicyclohexylphosphino)ferrocene; R = Me or Ph). They will be required to obtain the cif files from the supporting information of a paper. They will then make a variety of measurments in the two stuctures. These measurements can be made using a variety of different freely available programs. Instructions are provided for Mercury 3.3 and Olex2. Finally, students will be required to provide a rationale for the differences in the two structures.

The Chemistry of Cooley's Anemia: A Case Study

Submitted by Chris Bailey / Wells College on Wed, 08/06/2014 - 11:36
Description

In this case study, information is presented to students in the form of a dialog between a physician and two parents who have just learned that their child has thalassemia (Cooley’s Anemia). The treatment for this disorder requires a lifetime commitment to whole blood transfusion and chelation therapy (both administered on a daily to weekly basis); the biggest obstacle to long term survival is patient non-compliance.

Nitrogen Fixation: A Structural Inorganic Mystery?

Submitted by Jodi O'Donnell / Siena College on Mon, 08/04/2014 - 16:17
Description

 

These slides describe the recent literature on the structure of the iron sulfur cluster of nitrogenase active site, FeMo-co.  Included are: a comparison of industrial vs. biological ammonia production, several crystal structures from the literature including the unknown until recently hypervalent carbon atom in the center, and a brief mention of the troubling sterics of the active site as crystallized.
