Lithium Diazenide Surprise!

Submitted by Maggie Geselbracht / Reed College on Fri, 05/31/2013 - 23:00
Description

Students in a sophomore-level inorganic chemistry course were asked to read the paper “High-Pressure Synthesis and Characterization of the Alkali Diazenide Li2N2” (Angew. Chem. Int. Ed. 2012, 51, 1873-1875. DOI: 10.1002/anie.201108252) in preparation for a class discussion.  For many students, this was a first exposure to reading the primary literature.

This website is a free and comprehensive resource that is a collection of open college courses that spans videos, audio lectures, and notes given by professors at a variety of universities. The website is designed to be friendly and designed to be easily accessed on any mobile device.

University of Cambridge Teaching and Learning Packages

Submitted by Barbara Reisner / James Madison University on Fri, 01/25/2013 - 05:00
Description

These are a group of outstanding resources for materials science and solid state chemistry. They are all tutorials with Flash animation. I find these to be an excellent review for myself and an excellent primer for my students. Because there are so many useful tutorials on the site, I've highlighted the ones that I think are most appropriate for use in an undergraduate curriculum. These range from introductory to advanced material.

Crystallography & Diffraction

Exploring the Nanoworld Innovating through Materials from the University of Wisconsin Madison

Submitted by Patricia Stan / Taylor University on Thu, 07/19/2012 - 13:29
Description

This is a great web resource for all types of nano materials.  There are lesson plans, demos, activites, labs and lots of background information.  It is very easy to navigate and there are videos of the labs so you can see each step - very useful when doing a type of synthesis or technique new to you.

Colored Note Cards as a Quick and Cheap Substitute for Clickers

Submitted by Chris Bradley / Mount St. Mary's University on Tue, 07/17/2012 - 10:23
Description

For many years I have resisted using clickers, mainly because at our university there is no standard universal clicker. I wanted to keep student costs as low as possible but also desired the type of live feedback during a lecture that clicker questions can provide. In both my general chem. (200-300 students) and upper division courses (50-75 students), I now pass out 4 or 5 colored notecards on the first day of class and make sure everyone has one of each color.

Hard-Soft Acid-Base Theory in Action: A New Ion-Exchange Material for Sequestering Heavy Metals

Submitted by Maggie Geselbracht / Reed College on Sun, 06/26/2011 - 00:30
Description

This paper from Chemistry: A European Journal by Manolis Manos and Mercouri Kanatzidis (link provided below in Web Resources) describes the ion-exchange chemistry of a layered sulfide (KMS-1) that exhibits an enhanced preference for soft metal cations (Cd2+, Pb2+, and Hg2+) replacing K+ in between the metal sulfide layers of KMS-1.  Not only does this paper provide a practical application of hard-soft acid-base theory (HSAB), but it provides an accessible introduction to the technical literature for undergraduates, par

Synthesis of Zinc Oxide Nanoparticles and Characterization by Powder X-ray Diffraction

Submitted by Catherine Oertel / Oberlin College on Sat, 06/25/2011 - 13:16
Description

I designed this lab experiment to introduce students to the uses of powder X-ray diffraction in the context of the synthesis of a technologically relevant material. Zinc oxide nanoparticles can be synthesized readily with reagents that are inexpensive and relatively benign with regard to student use and waste disposal. Two experiments described in J. Chem.

Catalysis using functionalized mesoporous silica

Submitted by Randall Hicks / Wheaton College on Wed, 05/25/2011 - 10:30
Description

This paper, while not fundamentally groundbreaking, serves as a nice introduction to the field of mesoporous materials. I like that it covers synthesis, characterization, and an application of the materials. I have used this paper in our senior seminar course as the basis for discussion of this area of chemistry. Discussion questions cover aspects of sol-gel chemistry, powder diffraction, gas adsorption, IR, solid state NMR, UV-Vis, and catalysis.  

Powder Diffraction Crystallography Instructional Materials

Submitted by Barbara Reisner / James Madison University on Mon, 06/28/2010 - 11:03
Description
Brian Toby (Argonne National Labs) has assebled an excellent series of tutorials on using the Rietveld analysis technique for powder diffraction data. Tutorials range from an "Introduction to Crystallography" and "Getting Started with Rietveld" to using the "Le Bail Intensity Extraction" Method to "Advanced Rietveld Techniques."
