Relating local industry to primary literature: The David Sarnoff/RCA Project
Description
Literature summary through student presentation - free choice of topic.
Description
(1) Student choses and reads a journal article of his/her choice that is related to a topic we have discussed during the semester. (i.e. atomic structure, MO theory, group theory, solid state structure, band theory, coordination chemistry, organometallics, catalysis). Suggested journals include, but are not limited to JACS, Inorg. Chem., Organometallics, Angew. Chem., JOMC, Chem. Comm.)
(2) Student answers the following questions regarding their chosen article:
(a) Describe, in 1 or 2 sentences the goal of this work.
The Synthesis and Characterization of Cobalt Spinels
Description
In this lab, students will use solid-state methods to synthesize cobalt and chromium spinels, ZnCr2O4, ZnCo2O4, CoAl2O4, and CoCr2O4. They will (1) characterize their structure with X-ray powder diffraction (XRD) and (2) characterize the color using UV-Vis diffuse reflectance spectroscopy.
X-ray absorption spectroscopy and its applications to LFT
Description
This series of (not five) slides introduces X-ray absorption spectroscopy (XAS), specifically XANES (X-ray absorption near-edge structure). There is background in basic theory, the general technique including synchrotron radiation sources, and two specific examples from the literature that apply XANES spectra to (1) oxidation state and effective nuclear charge of sulfur in various compounds such as sulfates, and (2) measurement of energy levels in MO diagrams of coordination compounds (i.e., LFT). Point (2) is analogous to showing PES peaks alongside MO diagrams for diatomics.
Chemical Acrostics for Fun and Active Learning
Description
Chemical acrostic is used as a teaching tool in descriptive inorganic chemistry. This is an active learning approach to engage the students with a fun classroom activity. The acrostics are designed by Simon Cotton and published in the Royal Society of Chemistry's education resource magazine "The Mole." The students are divided into groups of two or three to work on the acrostics. To come up with the answers, the students engage in meaningful group discussions that enhance conceptual understanding.
Trends in Measured Redox Potentials and Computed Molecular Orbital Energies of Derivatized Buckminsterfullerenes
Description
In this project students are asked to reproduce published calculations of molecular orbital energies of a series of derivatized fullerenes and correlate them with published reduction and oxidation potentials obtained from cyclic voltammetry. The particular subset of the derivatives to be studied are chosen by the student and this choice is part of the learning activity. The students then carry out additional calculations using other theoretical models to see whether they improve the correlation between computed and experimental properties.
Band Structures, Electronic and Optical Properties of Metals, Semiconductors, and Insulators
I created this Collection of Learning Objects (LOs) at the IONiC VIPEr TUES 2013 Workshop: Solid State Materials for Alternative Energy Needs held at Penn State University. The overall theme of the Collection is electronic and optical properties of metals, semiconductors, and insulators. Most of the learning objects either require knowledge of or explicitly refer to band structures, either at a basic level or a more advanced level. Some LOs also deal with extended structures, un
Symmetry, Group Theory, and Computational Chemistry
These Learning Objects were used in an advanced undergraduate chemistry course that used computational chemistry as an integrative tool to help students deepen their understanding of structure, bonding, and reactivity and practice their integrative expertise by addressing complex problems in the literature and in their own research.
Synthesis and Analysis of the POM Ammonium Decavanadate, (NH4) 6V10O28*6H2O
Description
Synthesis of ammonium decavanadate, and analysis via IR, UV-Vis and quantitative titration. Time: 1.5 lab periods
Purpose
The purpose of this lab experiment is to expose students to the synthesis of a colored POM, and to connect the use of standard analytical techniques to this new type of compound. It introduces the use of IR spectroscopy of inorganic materials.
Introduction
Virtual Schlenk Line
Description
This website provides a link to a simple downloadable program that introduces students to a Schlenk line through a series of short animations. It is designed for Windows (does not appear to work on Windows 8 or on Macs). While a bit rudimentary, it does a nice job of showing students the basic setup, discussing safety concerns with the liquid nitrogen trap, and outlining the general procedure for starting up and shutting down the Schlenk line.
