Energy Nugget: Methane to Methanol

Submitted by Hilary Eppley / DePauw University on Thu, 01/12/2012 - 05:40
Description

This learning object was developed with a lot of help from B. Scott Williams from the Keck Science Department of the Claremont Colleges for my junior/senior level course in 2009.   This object is a literature discussion on the topic, but Scott and I hope to add a 5-slides about learning object to go with it shortly.   The primary literature article used for the discussion is “Characterization of a Rhodium(I) sigma-Methane Complex in Solution,” by Wesley H. Bernskoetter, Cynthia K. Schauer, Karen I.

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.  

Exploring Photographic Chemistry

Submitted by Rebecca M. Jones / George Mason University on Wed, 03/09/2011 - 15:27
Description
This set of experiments is a fun way for students to be experience interesting redox chemistry.  I have taught this series of experiments in my first semester junior level inorganic class for the past 5 years.  In part 1, students create salted paper prints with different binders.  Part 2 involves the synthesis of Prussian blue as cyanotypes are formed on paper and cloth.  In part 3, students design t

Pigment Syntheses and Qualitative Analysis

Submitted by Rebecca M. Jones / George Mason University on Wed, 03/09/2011 - 15:13
Description

This set of experiments provides an introduction to simple inorganic synthesis and qualitative analysis of inorganic pigments.  I have taught this series of experiments in my first semester junior level inorganic class for the past 5 years.  In part 1, students synthesize five inorganic pigments.  Part 2 involves identifying an unknown inorganic white pigment by chemical and physical tests.  These

The Electronic Properties of tris-(2,2'-bipyridine)-ruthenium(II) Lab Experiment(s)

Submitted by Jared Paul / Villanova University on Wed, 02/02/2011 - 19:41
Description

This is a lab experiment designed to cover an array of techniques, including metal complex synthesis, spectroscopy and electrochemistry.  Overall, the goal is to synthesize the metal complex Ru(bpy)32+, exchange the counter ion to demonstrate changes in solubility, absorbance and emission properties (including excited state quenching through energy and electron transfer, and ground state oxidation), as well as cyclic voltammetry of the complex.

Synthesis and characterization of 12-tungstosilicic acid - a modification

Submitted by Randall Hicks / Wheaton College on Mon, 11/15/2010 - 23:25
Description
This lab experiment is an update on the synthesis of the title acid. An account of this synthesis can be found in William Jolly's book, The Synthesis and Characterization of Inorganic Compounds. The synthetic procedure is reliable and was retained. However, I modified some content and added components to extend to a two-week experiment. This lab now covers the synthesis, an acid-base titration with error analysis, and the use of TGA to complement the titration results.

The organometallic hypertext book

Submitted by Madeleine Schultz / Queensland University of Technology on Mon, 09/06/2010 - 06:11
Description

I am sure most people already use this but I always refer to students to the Organometallic hypertext book. It has excellent explanations of topics such as back-donation in organometallic complexes.

First Isolation of the AsP3 Molecule

Submitted by Anne Bentley / Lewis & Clark College on Fri, 09/03/2010 - 13:47
Description

Early in 2009, Christopher Cummins’ group at MIT reported (in Science) the synthesis of AsP3, a compound that had never been isolated at room temperature.  Later that year, a full article was published in JACS comparing the properties and reactivity of AsP3 to those of its molecular cousins, P4 and As4.  The longer article is full of possibilities for discussion in inorganic chemistry courses, with topics including periodic trends, NMR, vibrational spectroscopy, electrochemistry, molecular orbital theory, and coordination chemistry.
