Crystal Lattice Structures Web Site
A really nice site with several lattice structures indexed by several methods, and new structures are continuously being added. I find it useful for getting images for problems sets and exams.

These 6 slides introduce the nomenclature used to describe the stereochemistry of various polypropylenes (PPs) that can be synthesized by metallocene-catalyzed polymerizations. Although PP is the specific polymer discussed, the nomenclature applies to other alpha-olefin polymerizations.
This screencast is a brief introduction to some of the features of VIPEr.
This paper from Chemistry: A European Journal by Manolis Manos and Mercouri Kanatzidis (link provided below in Web Resources) describes the ion-exchange chemistry of a layered sulfide (KMS-1) that exhibits an enhanced preference for soft metal cations (Cd2+, Pb2+, and Hg2+) replacing K+ in between the metal sulfide layers of KMS-1. Not only does this paper provide a practical application of hard-soft acid-base theory (HSAB), but it provides an accessible introduction to the technical literature for undergraduates, par
This is a simple and quick demonstration of the process oftempering of a solid, and the dramatic
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.
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.
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
