Supramolecular Chemistry Videos

Submitted by Shirley Lin / United States Naval Academy on Sun, 03/03/2019 - 08:08

The Rebek Laboratory homepage contains information on and molecular visualizations of a variety of host-guest systems developed by the research group over several decades. The theme behind this set of examples is the use of hydrogen-bonding to achieve self-assembly. Under the "Research" tab, one can find four videos with narration: an introduction to molecular assembly and three videos of specific examples of self-assembled host systems (the cavitand, the cylinder and the volleyball).

Venn Diagram activity- What is inorganic Chemistry?

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 01/03/2019 - 18:02

This Learning Object came to being sort of (In-)organically on the first day of my sophomore level intro to inorganic course. As I always do, I started the course with the IC Top 10 First Day Activity. (  One of the pieces of that In class activity asks students- novices at Inorganic Chemistry- to sort the articles from the Most Read Articles from Inorganic Chemistry into bins of the various subdisciplines of Inorganic Chemistry.

Developing methodology to evaluate nanotoxicology: Use of density.

Submitted by Tori Forbes / University of Iowa on Fri, 06/15/2018 - 17:30

This activity is designed to relate solid-state structures to the density of materials and then provide a real world example where density is used to design a new method to explore nanotoxicity in human health.  Students can learn how to calculate the density of different materials (gold, cerium oxide, and zinc oxide) using basic principles of solid state chemistry and then compare it to the centrifugation method that was developed to evaluate nanoparticle dose rate and agglomeration in solution.


The Preparation and Characterization of Nanoparticles

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

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. 

An ion exchange method to produce metastable wurtzite metal sulfide nanocrystals

Submitted by Janet Schrenk / University of Massachusetts Lowell on Sat, 06/03/2017 - 11:25

In this literature discussion, students use a paper from the literature to explore the synthesis, structure, characterization (powder XRD, EDS and TEM) and energetics associated with the production of a metastable wurtzite CoS phase. Students also are asked define key terms and acronyms used in the paper; identify the goal of the experiments and determine if the authors met their goal. They examine the fundamental concepts around the key crystal structures available.  


Quantum Dot Growth Mechanisms

Submitted by Chi / United States Military Academy on Sat, 06/03/2017 - 11:01

This literature article covers a range of topics introduced in a sophomore level course (confinement/particle-in-a-box, spectroscopy, kinetics, mechanism) and would serve as a an end-of-course integrated activity, or as a review activity in an upper level course.

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.

Nanomaterials Chemistry

This list includes a number of LOs to help in teaching nanomaterials subjects; however, it is not exhaustive.

Copper Oxide Crystal Growth

Submitted by Ellen Steinmiller / University of Dallas on Mon, 06/29/2015 - 14:49

Students in a 2nd year inorganic class read an article describing the effect of additives on the final morphology of copper oxide. (Siegfried, M.J., and Choi, K-S, “Elucidating the Effect of Additives on the Growth and Stability of Cu2O Surfaces via Shape Transformation of Pre-Grown Crystals”J. Am. Chem. Soc., 2006, 128 (32), pp 10356–10357.
