Putting electrochemistry to use: Design of new lithium-ion battery anodes

Submitted by Maggie Geselbracht / Reed College on Fri, 11/28/2008 - 20:55
Description
This learning object focuses on a discussion of a recent paper that highlights the application of electrochemistry in inorganic materials chemistry: “Direct Electrodeposition of Cu2Sb for Lithium-Ion Battery Anodes” by James M. Mosby and Amy L. Prieto, J. Am. Chem. Soc.

Hands-On Experience with Close Packing

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 10:19
Description
This is a really fun Challenge where student use two colors of marbles to simulate close packing. It culminates in them creating the face-centered cube "hidden" in hexagonal close packing.

Solid-state model building exercise

Description

Students construct models of ionic solids in class and answer a series of questions about the structures.

Lanthanum gallium bismuthide

Submitted by Maggie Geselbracht / Reed College on Wed, 04/02/2008 - 01:55
Description
This paper describes the synthesis and characterization of a new structurally interesting polybismuthide. The bonding is understood through band structure calculations and a retrotheoretical approach, analyzing the interactions of smaller substructures. Discussion is focused on the Ga-Ga bonding interactions and the weaker Ga-Bi and Bi-Bi interactions within the one-dimensional bismuth ribbons.

Miessler and Tarr: Inorganic Chemistry, 3rd. Ed

Submitted by Nancy Williams / Scripps College, Pitzer College, Claremont McKenna College on Fri, 03/28/2008 - 16:44
Description

Miessler and Tarr is an inorganic textbook which is is best suited to an upper-division one-semester inorganic course, though there is more material than can be covered in a single semester, so some choice of topics is necessary.  It is very well suited for a course oriented around structure, bonding, and reaction chemistry of transition metal compounds, but is very limited in its treatment of solids, main-group, descriptive chemistry, and bioinorganic.  Pchem would be helpful but is not necessary.  In particular, the treatment of MO theory is very in-depth.  The quality of end-of chapter p

Housecroft and Sharpe: Inorganic Chemistry, 3ed

Submitted by Lori Watson / Earlham College on Wed, 03/26/2008 - 20:01
Description

Housecroft and Sharpe (Inorganic Chemistry, 3ed): This is a comprehensive inorganic textbook designed primarily for students at the Junior/Senior level. P-Chem would not be needed as a prerequisite for this text, but would be helpful. It includes both theoretical and descriptive material along with special topics, enough for a two semester course though it is easily adaptable to a one-semester "advanced inorganic" course by choosing only some topics. It is written in a clear and generally readable style and the full-color graphic contribute to student understanding.

From molecules to solids: Lewis structures

Submitted by Barbara Reisner / James Madison University on Sun, 11/18/2007 - 13:19
Description

I have students construct Lewis structures on the board starting at the noble gases and working backwards to the group 14 elements.  We talk about both second period then heavier elements.  As we move across the period we transition from molecular solids to extended solids.  

This is a nice transition from molecular chemistry to extended compounds.  I use this as a bridge into the solid state portion of the course because it allows me to review Lewis structures, trends in bond energies, and provide some descriptive chemistry information. 

Looking at Solid State Structures

Submitted by Barbara Reisner / James Madison University on Sat, 11/17/2007 - 18:05
Description

I find that students get a better understanding of solid state structure by playing with models.  I give students two fifty-minute class periods to look at the structure types that we discuss in class.  This is an old in-class activity that needs massive updating.

In this activity,  students look at the holes in different lattice types (simple cubic, ccp, hcp) and the CsCl, NaCl, CdI2, ZnS, and spinel structure types.

Determining Molecular Structure: An Experimental Simulation of X-ray Diffraction

Submitted by Maggie Geselbracht / Reed College on Sat, 11/17/2007 - 16:53
Description
­This activity introduces students to the symmetries of 2-D repeating patterns and X-ray diffraction. Using small lasers and Optical Transform slides (available from the Institute for Chemical Education), students qualitatively and quantitatively investigate the relationships between the sizes and symmetries of unit cells and the effects observed in diffraction patterns.
