The Bilbao Crystallographic Server provides access to crystallographic programs, tools, and databases. The tools are grouped according to type: space groups retrieval; group-subgroup relations of space groups; representation theory applications; solid state theory applications; structure utilities; and subperiodic groups (layer, rod, and frieze groups retrieval tools). The Incommensurate Crystal Structure Database (ICSDB) provides access to four categories of data: general (chemical information and publication data); average structure (cell, symmetry, atom sites, and experimental data for the average structure); modulated structure (cell, symmetry, atom sites, and experimental data for the modulated structure); and modulation parameters (descriptions of the modulation, wave vectors, and atom sites modulations).

ElectroSim 2.0: Interactive Simulations of Basic Electronic and Operational Amplifier Circuits
Conditions of Use:
Read the Fine Print
Rating

ElectroSim 2.0 is a collection of theory-based interactive simulations of simple electronic circuits, suitable for a course in elementary practical instrumentation electronics; the simulations were created for use in an "Electronics for Chemists" course at the University of Maryland. Available for free download, the software can be used on Macintosh or Windows computers (a special utility is required to run it under Windows). Over twenty common analog circuits are included in the package. For each simulation, properties such as voltage, resistance, current, and capacitance can be changed to see how particular circuits behave under different operating conditions. There are easy to follow instructions and simple controls.

Interactive Computer Models for Analytical Chemistry Instruction
Conditions of Use:
Read the Fine Print
Rating

This collection of interactive computer models and simulations of common instruments and techniques used in analytical chemistry is available for free download. The software can be used on Macintosh or Windows computers. Most of the models have a point-and-click interface; users click buttons and drag sliders to control variables, and the models respond dynamically. They were designed to be used by individual students either as homework assignments, for in-class use in a computer lab environment, or in the laboratory for the analysis of student-generated data. Some of the models can be used by the instructor in lecture-demonstration environments. Most of them come with student assignment handouts attached. The mathematical basis for each model is described, including all cell definitions and equations.

NanoSpace, a free website developed by the Rensselear Polytechnic Institute, was created to increase science literacy utilizing an amusement park. NanoSpace is designed to teach science to elementary and middle school students through more than 25 games and animations that entice kids to learn more about atoms and molecules in NanoSpace. Visitors can try to beat the clock in the Periodic Memory and click-and-drag atoms to construct molecules in "Build `Em." Answer multiple-choice questions in "Who wants to be a Quidecillionaire?," and hope the answer is correct before you fall down to the bottom rung again.

This question-and-answer tutorial provides an introduction to quantum theory and the electron structure of the atom. Suitable for advanced high-school students and those beginning postsecondary education, this "quantum catechism" presents the basic concepts in an easily understood way and with a minimum of mathematical detail. Each question is linked to a relatively brief (several paragraphs long) answer. Topics include particles and waves, the nature of light, black body radiation, the photoelectric effect, the uncertainty principle, line spectra, the planetary model of the atom, Bohr's theory, and other subjects. A printable, PDF version of the document is available.
