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.

Assessing Chemical Hazards

Submitted by Anne Bentley / Lewis & Clark College on Tue, 10/14/2008 - 20:17
Description

This is a short activity I developed to help my students interpret Material Safety Data Sheets (MSDS). Students rank unknown compounds from least safe to most safe, and the compounds' identities are revealed. The class discusses other factors to consider in evaluating the safety of an experiment. The "MSDS activity" word document contains a more full description.

F-elements Lecture Material

Submitted by Bunzli Jean-Claude / Ecole Polytechnique Federale de Lausanne (EPFL) on Sat, 08/02/2008 - 18:06
Description
The goal of this course taught at the MSc level is to provide students with an overview of the properties of the f-elements, with reference to their multiple uses in our daily life and in high technology applications. The course is mainly focused on 4f elements with some reference to 5f elements as well.

Sherlock Holmes in Transition-Metal Chemistry

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 10:35
Description
This Challenge practices problem-solving and several different characterization techniques for coordination compounds. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.

Electron Counting and a Catalytic Reaction

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 10:30
Description
This Challenge shows a catalytic process, and especially gives practice on electron-counting in transition metal complexes. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.

Speed-Dating, Chemistry Style: HSAB Theory

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 10:24
Description

This is an interactive Challenge in which students have to find others in the room with whom they "match" as a hard or soft acid or base. It brings to life the way inorganic chemists think about HSAB. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.

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.

Aufbau Exercise

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 10:12
Description

This is a Challenge for the beginning of an Inorganic class, to remind students of the basics of Aufbau, etc. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games. You can pick and choose Challenges from our Web site to increase active learning in your classroom, and we ask that you contribute creative Challenges of your own to give a head start to teachers at other colleges and universities!

Battle of the Theories: Valence-Bond vs. Molecular-Orbital

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 10:04
Description

This Challenge practices both VB and MO models, and can be used to show the superiority of MO models for explaining simple molecules like O2 and CH4. It also demonstrates how scientists make rational choices between theories. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.
