This is a very brief introduction to the origin of color in nanoparticle systems. A link to a video is included in the slides that shows the addition of the reducing agent to the gold precursor solution. The link is also available as a Web Resourse (below).
Cmap Tools is a powerful free program that can be used to create concept maps. The program works on any platform.
Thanks to Kurt Birdwhistell for posting the link to this tool to the forum a while back.
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.
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 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.
Covers the geometries and symmetries of the seven crystal systems in an inquiry-based manner. 2-D paper templates are provided, which the students cut out, fold, and tape together to create 3-D representations of the seven crystal systems: triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic. The students can then use these to determine the geometries and symmetries of the systems for themselves.
All chemistry is learned best by "doing," and I believe this is especially true for determining molecular symmetry. This activity was designed to end a three-part lecture/activity on symmetry and point groups for my advanced inorganic class. I call this unit on symmetry a lecture/activity series because it was designed to be student-guided learning and requires the students to teach each other how to determine a molecular point group. I only gave one formal lecture on symmetry and point groups, which was followed by the symmetry scavenger hunt activity LO. Finally this assignment was do
Beginning with Volume 43, Issue 25, Inorganic Chemistry began publishing Forums.
Inorganic Chemistry Forums consist of a set of thematically linked papers from leading scientists on a multidisciplinary topic of growing interest. Papers present overviews, research perspectives and original research reports on the Forum theme and are highlighted on the cover of the journal issue in which they appear.
At this website students can access interactive game-like learning resources that cover a wide range of topics in general chemistry. These learning activities, which are in the form of flash cards, quizzes and matching games, will help student learn and review/drill important general chemistry topics.
Bob Morris of the University of Toronto created this website when he was teaching a class on Bioinorganic Chemistry.
