Applications of Frustrated Lewis Pairs (FLPs)

Submitted by Brad Wile / Ohio Northern University on Thu, 03/05/2020 - 11:22
Description

Short prompts for a mini review about recent applications in FLP chemistry. Trends in Chemistry also includes highlights and outstanding questions in the sidebar, which makes this an approachable review for students. 

ChemCrafter

Submitted by Michelle Personick / Wesleyan University on Mon, 03/02/2020 - 16:24
Description

ChemCrafter, from the Science History Institute (formerly the Chemical Heritage Foundation), is a free iPad app that mimics a classic chemistry set. It is set up as a game, with three sections: reactions with water, reactions with acid, and salts. The app shows the progress of the reaction (smoke, color change, etc.) when two elements are mixed in a reaction vessel, and also gives the change in enthalpy of the reaction.

Case Study: Animal Migration and Isotopes

Submitted by Lyndsay Munro / University of Nevada on Tue, 02/11/2020 - 15:11
Description

This is an in-class case study activity that introduces relevancy between atomic structure (specifically isotopes) and animal migration.  Students will apply their knowledge of isotopes, writing atomic symbols, and calculating average atomic mass while also connecting this information to another application (in this case animal migration).  

Inorganic Chemistry 2020

Submitted by Adam Johnson / Harvey Mudd College on Tue, 01/21/2020 - 17:35
Description

Inorganic chemistry interfaces and overlaps with the other areas of chemistry. Inorganic chemists  synthesize molecules of academic and commercial interest, measure properties such as magnetism and unpaired electron spin with sophisticated instruments, study metal ion uptake in living cells, and prepare new materials like photovoltaics. Inorganic chemistry is a diverse field, and we will only be able to touch on some of the chemistry of the 118 elements that currently reside in the periodic table.

Formal oxidation states in Ru-catalyzed water oxidation

Submitted by Margaret Scheuermann / Western Washington University on Fri, 01/17/2020 - 16:36
Description

This LO is an in-class assignment to prepare students for literature readings involving catalytic cycles in which multiple protons and electrons are transferred. Students practice assigning oxidation states to complexes with aquo, oxo, superoxo, and hydroperoxo ligands then use this information to analyze a proposed water oxidation mechanism from the literature.

Marvin suite from ChemAxon

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 01/09/2020 - 12:10
Description

It is important for students to be able to effectively communicate the results of their scientific work. This does not only inlcude written and oral communication, but the creation of appropriate representations of the complexes they have investigated. It is crucial that students learn how to draw molecules using electronic structure drawing programs, but site licenses for structure drawing programs can be prohibitive for some institutions.

How to Read a Journal Article: Analyzing Author Roles and Article Components

Submitted by Catherine McCusker / East Tennessee State University on Wed, 01/08/2020 - 21:09
Description

This literature discussion uses a recently published article on solvatochromic Mo complexes to introduce students to the different components of a research article. The activity is divied into to two parts. Before class students read the paper and focus on defining terms, investigating the "meta" data of the paper, and the different sections iof the paper. In class the students work in groups to investigate the scientific content of the paper

Visualization of Solid State Structures using CrystalMaker and Physical Models

Submitted by Hilary Eppley / DePauw University on Wed, 01/08/2020 - 14:17
Description

This first-year laboratory is designed to give students an introduction to basic solid-state structures using both CrystalMaker files and physical models. I think this would work in a foundations level inorganic course as well. It could be used alternatively as an in-class activity or take-home problem set depending on the instructor. It was adapted by me and later, David Harvey, from an original activity that was posted as an educational resource on the CrystalMaker website in the mid 2000s.  

Porphyrin UV-Vis

Submitted by Matthew Riehl / Minnesota State University, Mankato on Mon, 11/18/2019 - 16:30
Description

The UV-vis spectra of porphyrins are among the most recognizable spectra in the chemical literature, but the electronic transitions that lead to the observed specta are not as well known.  This presentation provides an introduction to the structure and numbering of porphyrins and the origin of the bands observed in the near UV and visible region, based on the work done by Martin Gouterman beginning in the late 1950's.    

2019 Nobel Prize - Li-ion battery LOs

Submitted by Barbara Reisner / James Madison University on Wed, 10/09/2019 - 20:28

Congratulations to the 2019 recipients of the Nobel Prize - John B. Goodenough, M. Stan Whittingham and Akira Yoshino. It's a well deserved honor!

There are several LOs on VIPEr that talk about lithium ion batteries and related systems. The 2019 Nobel is a great opportunity to include something about these batteries in your class.

I hope to see more LOs in the coming weeks so we can bring this chemistry into our classrooms!
