The Preparation and Characterization of Nanoparticles

Submitted by Kyle Grice / DePaul University on Wed, 06/13/2018 - 23:23
Description

This is a nanochemistry lab I developed for my Junior and Senior level Inorganic Chemistry course. I am NOT a nano/matertials person, but I know how important nanochemistry is and I wanted to make something where students could get an interesting introduction to the area. The first time I ran this lab was also the first time I made gold nanoparticles ever! 

We do not have any surface/nano instrumentation here (AFM, SEM/TEM, DLS, etc... we can access them at other universities off-campus but that takes time and scheduling), so that was a key limitation in making this lab.

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.

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.

Inorganic Chemistry

Description

Modern theories of atomic structure and chemical bonding and their applocations to molecular and metallic structures and coordination chemistry.

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.

Metal Tropocoronand Complexes

Submitted by Anthony L. Fernandez / Merrimack College on Wed, 01/17/2018 - 13:36
Description

This exercise looks at the metal complexes of tropocoronand ligands, which were first studied by Nakanishi, Lippard, and coworkers in the 1980s. The size of the metal binding cavity in these macrocyclic ligands can be varied by changing the number of atoms in the linker chains between the aminotroponeimine rings, similar to crown ethers. These tetradentate ligands bind a number of +2 metal centers (Cd, Co, Cu, Ni, and Zn) and the geometry of the donor atoms around the metal center changes with the number of atoms in the linker chains.

Inorganic and Materials Chemistry

Submitted by Karen S. Brewer / Hamilton College on Mon, 01/15/2018 - 17:12
Description

Topics in inorganic chemistry, including periodicity and descriptive chemistry of the elements, electrochemistry, transition metal coordination chemistry, and the structure and properties of solid state materials. Laboratories emphasize synthesis and characterization of inorganic coordination compounds, electrochemistry, and inorganic materials. This course satisfies the second semester of a one-year General Chemistry requirement for post-graduate Health Professions programs. Prerequisite, 120 or 125. Three hours of lecture and three hours of laboratory.
