Includes exercises and problems. Crossed stereoscopic diagrams enhance the understanding of three-dimensional structures. http://www.merlot.org/merlot/viewMaterial.htm?id=76764 A simulated experiment for determining the densities of liquids and solids by observing the weight of an object in air and immersed in a liquid. http://www.merlot.org/merlot/viewMaterial.htm?id=412685 Science channel site which has video clips of the show, "How Its Made." These can be used in a variety of ways in the classroom. For example showing how aluminum foil is made can help explain properties like malleability of metals. http://www.merlot.org/merlot/viewMaterial.htm?id=577613 Introduction to Solid State Chemistry is a one-semester college course on the principles of chemistry. This unique and popular course satisfies MIT's general chemistry degree requirement, with an emphasis on solid-state materials and their application to engineering systems. You'll begin with an exploration of the fundamental relationship between electronic structure, chemical bonding, and atomic order, then proceed to the chemical properties of "aggregates of molecules," including crystals, metals, glasses, semiconductors, solutions and acid-base equilibria, polymers, and biomaterials. Real-world examples are drawn from industrial practice (e.g. semiconductor manufacturing), energy generation and storage (e.g. automobile engines, lithium batteries), emerging technologies (e.g. photonic and biomedical devices), and the environmental impact of chemical processing (e.g. recycling glass, metal, and plastic). http://www.merlot.org/merlot/viewMaterial.htm?id=658498 A planar hexagonal lattice is rolled up into a cylinder. This can be an illustration of how a graphene sheet forms a nanotube of "armchair" geometry. This interactive demonstration permits the user to change various parameters of the graphene roll up format as it forms various dimensionality nanotubes. http://www.merlot.org/merlot/viewMaterial.htm?id=757815 Short (<1 min.) GIF format videos of interesting (read: violent) chemical reactions, often involving things that catch fire or blow up. Users can also submit GIFs of their own chemical reactions. http://www.merlot.org/merlot/viewMaterial.htm?id=419612 This is an online lab that shows how to chemically separate and deduce the proportions of three different components in a mixture. http://www.merlot.org/merlot/viewMaterial.htm?id=512229 This is a free, online textbook offered by Bookboon.com. Topics covered include:1. Introduction2. Single component systems3. Multicomponent systems4. The ideal solution model5. Partial molar properties6. Nonideal solutions7. Stability8. Solid-liquid equilibrium9. Gas solubility and Henry’s law10. Equations of state11. Thermodynamics from equations of state12. Chemical reaction equilibria http://www.merlot.org/merlot/viewMaterial.htm?id=300593 This series of films explores a broad range of subjects in superconductivity, featuring interviews with leading world experts in academia and industry. The history and theory of superconductivity, methods of superconductor synthesis and characterisation, industrial production and applications are all covered in detail. The videos are available online for streaming and downloading free of charge, alongside a growing collection of questions, links and related information. The Lectures on Superconductivity are designed for undergraduate and postgraduate students of physics, chemistry and materials science, but many films will be of interest to a wider audience. http://www.merlot.org/merlot/viewMaterial.htm?id=658522 Optical properties such as dipole moment, oscillator strength, absorption and energy for graphene are available in an interactive Wolfram style demonstration. This Demonstration plots the observables relevant for understanding the optical properties of graphite and related materials (carbon nanotubes) over the hexagon of the 2D Brillouin zone (BZ) of a single graphitic sheet (graphene):
