Redox Chemistry and Modern Battery Technology

Submitted by Zachary Tonzetich / University of Texas at San Antonio on Mon, 04/10/2017 - 11:33

This In-Class Activity is a series of instructor-guided discussion questions that explore lithium-ion batteries through the lens of simple redox chemistry. I use this exercise as a review activity in my Descriptive Inorganic Chemistry course to help prepare for examinations. However, my primary purpose with this exercise is to impress upon students how basic concepts in redox chemistry and solid-state structure are directly relevant to technologies they use everyday.

Nanomaterials for Carbon Dioxide Reduction

Submitted by Anne Bentley / Lewis & Clark College on Mon, 03/27/2017 - 12:58

This literature discussion is based on an article describing the use of copper nanoparticles on an N-doped textured graphene material to carry out the highly selective reduction of CO2 to ethanol (Yang Song et al., “High-Selectivity Electrochemical Conversion of CO2 to Ethanol using a Copper Nanoparticle / N-Doped Graphene Electrode” ChemistrySelect 2016, 1, 6055-6061.  DOI: 10.1002/slct.201601169). The article provides a good introduction to the concepts of electrochemical reduction, selectivity and recycling of fossil fuels.

In-class peer review

Submitted by Chantal Stieber / Cal Poly Pomona on Fri, 03/03/2017 - 17:15

This activity includes questions for students to answer to help guide them through the process of peer review. It was designed to assist students in writing peer reviews for research reports written by their classmates, but could be applied to literature articles as well.

Inorganic Chemistry for Geochemistry and Environmental Sciences Fundamentals and Applications by George W. Luther III

Submitted by Rachel Narehood Austin / Barnard College, Columbia University on Wed, 01/04/2017 - 16:10

This is a great new textbook by George Luther III from the University of Delaware.  The textbook represents the results of a course he has taught for graduate students in chemical oceanography, geochemistry and related disciplines.  It is clear that the point of the book is to provide students with the core material from inorganic chemistry that they will  need to explain inorganic processes in the environment.

X-ray Crystallography

Submitted by David J Harding / Walailak University on Thu, 12/15/2016 - 22:58

The website shared here includes excellent simulations concerning a wide variety of techniques commonly used in materials science and inorganic chemistry. I have found it particularly useful for X-ray crystallography as the simulations help understand the lectures. 

Close Packing Activity

Submitted by George Lisensky / Beloit College on Tue, 06/28/2016 - 11:47

Many extended structures can be viewed as close-packed layers of large anions, with the smaller cations fitting in between the anions. Larger holes between close-packed anions can hold cations with octahedral coordination. Smaller holes between close-packed anions can hold cations with tetrahedral coordination. The online jsmol resources show these layers and their holes.

Online Homework for a Foundations of Inorganic Chemistry Course

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

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.

Solid State Stoichiometry Activity

Submitted by George Lisensky / Beloit College on Mon, 06/27/2016 - 17:11

The goal of this activity is to have students calculate the empirical formula of a compound given the contents of a unit cell. 

A repeating building block, or unit cell, is used to represent extended structures since shifting a unit cell along its edges by the length of the edge will exactly replicate the extended structure.

Solid State Stoichiometry Online

Submitted by George Lisensky / Beloit College on Mon, 06/27/2016 - 15:10

The page has JSmol structures for unic cells including cubic, body centered cubic, and face centered cubic unit cells as well as for CsCl, Ni3Al, Cu2O, NaCl, CaF2, ZnS, diamond, Li3Bi, NaTl, NiAl and ReO3The advanced page also has triclinic, monoclinic, hexagonal, orthorhombic, and tetragonal cells with all possible centering.

Visualizing solid state structures using CrystalMaker generated COLLADA files

Submitted by Barbara Reisner / James Madison University on Wed, 06/22/2016 - 16:59

Although I’m a solid state chemist, I still find it difficult to teach the visualization of solid state structures. I’m interested in any tool that helps my students visualize solids. My experience is that the more representations students can master, the more likely they are to find one that helps them understand solid state structures.

I’ve used many tools. These include
