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?

Online Homework for a Foundations of Inorganic Chemistry Course

Submitted by Sabrina Sobel / Hofstra University on Mon, 06/27/2016 - 18:08
Description

The Committee on Professional Training (CPT) has restructured accreditation of Chemistry-related degrees, removing the old model of one year each of General, Analytical, Organic, and Physical Chemistry plus other relevant advanced classes as designed by the individual department. The new model (2008) requires one semester each in the five Foundation areas: Analytical, Inorganic, Organic, Biochemistry and Physical Chemistry, leaving General Chemistry as an option, with the development of advanced classes up to the individual departments.

"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. 

Analyzing a journal article for basic themes, roles of authors, and the scientific method

Submitted by Darren Achey / Kutztown University on Thu, 07/02/2015 - 15:03
Description

This literature discussion is meant to give students an understanding of both the key concept-driven and more “meta” information of a literature paper.  Students will use Jillian Dempsey’s paper, “Electrochemical hydrogenation of a homogeneous nickel complex to form a surface-adsorbed hydrogen-evolving species,” to investigate paper authorship, how the scientific method is used in research, and how to understand the important findings of a research article.
