This 5 slides about gives a basic introduction to synchrotron radiation.  Information includes how the particles are accelerated, how they travel to the individual instruments, and where synchrotrons in the USA are located.

Building hybrid nanoparticles

Submitted by Angela Jovanovic-Bischof / Penn State on Thu, 06/27/2013 - 15:02
Description

This in-class activity was created at the NSF-TUES sponsored workshop at Penn State, June 2013.  It is based on the article from Ray Schaak’s group (Buck, Matthew R.; Bondi, James F.; Schaak, Raymond E. “A total-synthesis framework for the construction of high-order colloidal hybrid nanoparticles” Nature Chemistry 20124, 37-44, DOI: 10.1038/NCHEM.1195), which Ray presented at the workshop.

Kool-Aid analysis: Visible Spectroscopy and Paper Chromatography

Submitted by Megan Strayer / The Pennsylvania State University on Wed, 06/26/2013 - 13:55
Description

This lab experiment is designed to introduce the electromagnetic spectrum to non-science majors in a food chemistry course by using everyday food (i.e. Kool-Aid packets). Students will use a spectrophotometer to correlate wavelength to color, as well as determine the mass percent of certain colored dyes in a Kool-Aid sample. Paper chromatography is also introduced to determine the number of dyes in a Kool-Aid sample. This lab is adapted from Sigmann, S; Wheeler, D. J. Chem. Ed., 2004, 81, p. 1475.

Chimera - A Molecular Modeling Program

Submitted by Walter Flomer / St. Andrew's University on Wed, 06/26/2013 - 06:54
Description

Chimera is a program for interactive visualization and analysis of molecular structures and related data, including density maps, supramolecular assemblies, sequence alignments, docking results, trajectories, and conformational ensembles. High-quality images and animations can also be generated. Chimera includes documentation and tutorials, and can be downloaded free of charge for academic, government, non-profit, and personal use. Chimera was developed at UCSF and was funded by the National Institute of Health.

Synthesis and Analysis of the POM Ammonium Decavanadate, (NH4) 6V10O28*6H2O

Submitted by Sabrina Sobel / Hofstra University on Mon, 06/24/2013 - 20:35
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

A Visual Isotope Effect (a YouTube video)

Submitted by Dan O'Leary / Pomona College on Wed, 04/24/2013 - 17:46
Description

We have prepared a YouTube video demonstrating a visually accessible kinetic isotope effect in the Cr(VI) oxidation process, a reaction commonly encountered in introductory organic chemistry. The demo provides students with an opportunity to see an isotope effect and then understand how it can be used to provide mechanistic evidence for the identification of a rate-determining reaction step.

Energy Content and Properties of Fuels

Submitted by Matt Whited / Carleton College on Thu, 03/07/2013 - 10:59
Description

This is a group activity I developed for my "Introduction to Chemistry" class, which is set up primarily to cover the topics we consider to be prerequisites for the first course in our chemistry sequence at Carleton.  However, it covers aspects of thermodynamics (e.g., particularly Hess's Law) that are core topics for most intro courses.
