Cyclic voltammetry animations

Submitted by George Lisensky / Beloit College on Thu, 06/30/2016 - 07:17
Description

This is a question based approach for a discovery activity about cyclic voltammetry. The slider bar on a movie can used to control a variable and the displayed graph is updated to show the results. (You could also just play the movie to get an idea of what changes.)

The questions to be answered are

What is the shape of a cyclic voltammogram?

How are cyclic voltammograms affected by E0?

How are cyclic voltammograms affected by concentration?

How are redox equilibria affected by scan rate?

What if there are two reductions?

"Flipped Laboratory": A Discussion-based Electrochemistry Experiment for General Chemistry

Submitted by Samuel Esarey / University of Michigan on Mon, 06/27/2016 - 16:43
Description

This learning object is aimed at getting students to think critically about the data they collect in lab as they collect the data similar to how chemists typically conduct research.  They will be given a pre-lab video and a procedure prior to lab, conduct the experiment, and then upload their data to an Excel spreadsheet.  Students will then stay in their group to discuss the questions given to them on the worksheet in class with the instructor, and are allowed to continue working on them as a group up until the due date.

Kinesthetic Learning: Cyclic Voltammetry Mechanisms

Submitted by Chip Nataro / Lafayette College on Mon, 07/06/2015 - 17:03
Description

This activity was created as part of a primer on cyclic voltammetry for the 2015 TUES workshop. The activity is designed to have one person represent the potential and several other people represent the molecules in solution. By simply scanning (walking through the line of people) and shaking hands, several simple mechanisms can be illustrated. The use of a joy buzzer with the first hand shake is highly encouraged, but not at all necessary.

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. 

Inorganic Chemistry Wikibook

Submitted by Tom Mallouk / Pennsylvania State University on Wed, 05/27/2015 - 09:49
Description

Frustrated by the lack of inorganic textbooks that really fit my materials-oriented first-semester inorganic course, I embarked on a project with my students to create a free online textbook. The students did most of the heavy lifting, and I'm pleased to report that the next class to use the book rather liked it. It is still a work in progress, but I would like to encourage everyone to check it out and edit it if the spirit moves you.

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.

Maggie's LOs

Submitted by Chip Nataro / Lafayette College on Fri, 09/12/2014 - 17:25

Suite of LOs on Biomimetic Modeling

Submitted by Sheila Smith / University of Michigan- Dearborn on Mon, 08/04/2014 - 09:52

This suite of activities can be used as a unit exploring the use of small molecule models and biophysical techniques to illuminate complicated biomolecules.  The Parent LO:  Modeling the FeB center in bacterial Nitric Oxide reductase is a short, data-filled and well-written article that is approachable with an undergraduate's level of understanding.
