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.

Kinetics of electrocatalytic reduction of carbon dioxide by Mn catalysts containing bulky bipyridine ligands

Submitted by Kathleen Field / WGU on Thu, 07/02/2015 - 17:23
Description

This question set has students examine the kinetics of the electrocatalytic reduction of CO2 to CO described in Sampson, D.L.; Nguygen, D., Grice, K.A.; Moore, C.E.; Rheingold, A.L.; Kubiak, C.P. Manganese Catalysts with Bulky Bipyridine Ligands for the Electrocatalytic Reduction of Carbon Dioxide:  Eliminating Dimerization and Altering Catalysis.  J. Am. Chem. Soc. 2014, 136, 5460-5471. 

Ligand Effects in Pd-Catalyzed Cross Coupling

Submitted by Matt Whited / Carleton College on Fri, 01/09/2015 - 14:30
Description

This set of questions was used to promote discussion within small groups (3 to 4 students) on how changing ligand properties can have dramatic effects on the product distributions in Pd-catalyzed cross coupling reactions.  The questions are pretty difficult and not always straightforward, partly because they are derived from the primary literature and thus inherently "messy".

Literature Discussion of Hexamminecobalt(III) – Probing Metal Ion Binding Sites in Nucleic Acids by NMR Spectroscopy

Submitted by EGunn / Simmons College on Tue, 12/09/2014 - 13:56
Description

I use this literature discussion in my second year inorganic class as a follow-up to a lab experiment where students synthesize Werner complexes and then (with much guidance) analyze their IR spectra using symmetry and group theory arguments. This paper provides an excellent example of how cobalt complexes are used in modern applications, and serves as a bridge to bioinorganic chemistry, which is a central feature later in the course.

Thinking about Mechanisms of Metal Ion Exchange

Submitted by Chris Goldsmith / Auburn University on Wed, 11/12/2014 - 12:03
Description

Over the past several years, I've been doing this in-class exercise shortly after discussing mechanisms of ligand exchange. The exercise expands on the lecture material by having the students think about metal ions, rather than ligands, exchanging from a coordination complex. The students are encouraged to work in groups of 3-5 and actively discuss the material amongst themselves before we go over it as a class. I do not provide the students with the article ahead of time, so that they may come up with their own conclusions, as opposed to simply repeating those of the authors.

A Redox-Activated MRI Contrast Agent that Switches Between Paramagnetic and Diamagnetic States

Submitted by Vivian / Clemson University, Department of Chemistry on Wed, 07/16/2014 - 22:04
Description

Students are asked to read an article detailing the development of a cobalt-based MRI contrast agent ("A Redox-Activated MRI Contrast Agent that Switches Between Paramagnetic and Diamagnetic States", Tsitovich, P. B.; Spernyak, J. A.;  Morrow, J. R. Angew. Chem. Int. Ed. 201352, 14247-14250,  DOI: 10.1002/anie.201306394). Before coming to class the students are asked to answer a series of questions designed to guide them through the first half of the article, and to be prepared to discuss their answers in class.

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.

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

A Visual Isotope Effect (a YouTube video)

Submitted by Dan O'Leary / Pomona College on Wed, 04/24/2013 - 17:46
Description

We have prepared a YouTube video demonstrating a visually accessible kinetic isotope effect in the Cr(VI) oxidation process, a reaction commonly encountered in introductory organic chemistry. The demo provides students with an opportunity to see an isotope effect and then understand how it can be used to provide mechanistic evidence for the identification of a rate-determining reaction step.

General Chemistry Electronic Study Aids

Submitted by David Kreller / Georgia Southern University on Sun, 04/21/2013 - 13:14
Description

At this website students can access interactive game-like learning resources that cover a wide range of topics in general chemistry.  These learning activities, which are in the form of flash cards, quizzes and matching games, will help student learn and review/drill important general chemistry topics.
