Characterization and Investigation of a Binuclear Manganese(III)-Peroxo Metastable Intermediate

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 05/17/2018 - 16:15
Description

In this literature assignment, students are asked to read an article from the primary literature on a binuclear manganese-peroxo complex that is similar to species proposed to be involved in photosynthetic water splitting and DNA biosynthesis. The assignment contains 25 questions that are intended to guide students through the article and help them extract important information about the work. The completed questions are then used as the basis for an in-class discussion of model complexes, which leads to a more advanced discussion on the topic.

Description

When teaching my advanced bioinorganic chemistry course, I extensively incorporate structures from Protein Data Bank in both my assignments and classroom discussions and mini-lectures. I also have students access structures both in and out of class as they complete assignments.

3D Sym Op

Submitted by Caroline Saouma / Virginia Tech on Thu, 05/10/2018 - 20:31
Description

This is a great app that helps students see the symmetry in molecules. It allows you to choose a molecule (by name, structure, or point group) and display a 3D rendition of it. You can then have it display the symmetry elements, and/or apply all the symmetry operations. 

It is available for both android and apple phones: (probably easier to just search for it)

Developing Effective Lab Report Abstracts based on Literature Examples

Submitted by Nicole Crowder / University of Mary Washington on Tue, 05/08/2018 - 11:38
Description

For inorganic lab, I have my students write their lab reports in the style of the journal Inorganic Chemistry. The first week of lab, we spend time in small groups looking at several examples of recent articles from Inorganic Chemistry, focusing mainly on the experimental section and the abstract (as these are included in every lab report). We then come back together as a class to have a discussion of each of the sections in the articles. We discuss what was included in each section, what wasn’t included, and the style, tone, tense, and voice of each section.

Identifying Isomers

Submitted by Anne Bentley / Lewis & Clark College on Mon, 03/26/2018 - 13:27
Description

This in-class activity can be used to teach structural (or constitutional) isomers. This worksheet presumes that students have already had some experience with transition metal complexes such as determining metal oxidation state, recognizing the coordination sphere, and converting between formulas and structures.

Introduction to Pulsed Gradient Spin Echo DOSY

Submitted by Jacob Lutter / University of Southern Indiana on Thu, 02/08/2018 - 14:35
Description

Pulsed Gradient Spin Echo (PGSE) DOSY is a NMR technique used for determining the hydrodynamic radius of a molecule in solution by measuring the rate of diffusion. This technique requires a standard, usually tetrakis(trimethylsilyl)silane (TMSS). This activity will cover the basics of how PGSE works and includes built in animations to demonstrate how the nuclear magnetization is affected. Each slide has comments explaining the content for the user's convenience.

Streamlining Lab Report Grading: Errors Checklists

Submitted by Sabrina Sobel / Hofstra University on Mon, 01/22/2018 - 11:26
Description

I present a format for more effective communiction of errors in lab reports to students that I term Errors Checklists. Grading lab reports are one of the banes of our existence as professors. They are endless, unremitting papers that need to be scrutinized for accuracy, precision and understanding.

Isomerism in Coordination Complexes

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 01/18/2018 - 12:07
Description

Students are confronted with a number of new types of isomerism as they move from organic chemistry into inorganic chemistry. This can be confusing and students often have trouble visualizing structures and differentiating between isomers. In this exercise, students are asked to examine a number of different crystal structures from the Teaching Subset (distributed with Mercury version 3.10, early 2018) of the Cambridge Structural Database.
