Carnot pVCalculator
Last changed: 1 year 49 weeks ago
Overview
This package displays a Carnot pV diagram, consisting of isotherms and adiabats. You can change the isotherm temperatures and the separation between adiabats. You can also change the heat capacity ratio (gamma). The graph display updates within the given values of maximum pressure and minimum to maximum pressure. The work done by the system (clockwise cycle) is also displayed.

Chemical Bonding Curves Demo
Last changed: 17 weeks 2 days ago
Overview
This demonstration experiment shows the shapes of curves for potential energy and force for seven expressions commonly used in chemical bonding. They include ionic, Born-Mayer, Mie, Morse, Buckingham, Lennard-Jones 6-12, and Hooke's Law. The potential is in a dimensionless form of U/Uo versus distance as r/ro, where Uo is the potential at equilibrium distance ro. Force is dimensionless by its maximum value Fmax.

Fiber Composite Designer
Last changed: 49 weeks 4 days ago
Overview
This is a package that was developed to show how uniform, continuous, fiber composites behave using different input parameters. You can vary the densities, modulii, strengths, and fiber volume fraction. Graphs show the stress-strain behavior of the system, the intrinsic density or fiber weight fraction, and the iso-strain or iso-stress modulus or specific modulus of the composite. Everything is self-contained.

Gibb's Energy Curves
Last changed: 1 year 48 weeks ago
Overview
This shows the behavior of the Gibbs energy for a binary (A/B), two phase (alpha + beta) system.
The RED (alpha) phase curve will vary in position as a function of temperature (via the slider).

Kinetic Reaction Demo
Last changed: 21 weeks 3 days ago
Overview
This package is a demo that was created for a class in chemical kinetics. It illustrates the behavior of a chemical reaction network A <--> I --> P under various settings of rate constants, equilibrium conditions, and temperature.
Features
Use the checkboxes to turn on / off equilibrium of the first reaction and running the second reaction.
Use set variable inputs to change pre-factors, activation energies, and reaction enthalpy. Use a slider to set the equilibrium constant or reaction temperature.

MATLAB Functions
Last changed: 1 year 26 weeks ago
The biggest barrier to Igor adoption is usually knowledge of another environment's language. One of these is MATLAB. If a MATLAB users sits down to write Igor code, sometimes they have a hard time figuring out what the equivalent function in Igor is the function they know in MATLAB. And even if they find that function, if they haven't programmed in Igor, they might get stuck on the syntax.

Planck Distribution Plot
Last changed: 51 weeks 4 days ago
Overview
This is a demo experiment that shows the Planck distribution versus wavelength as a function of temperature. The intent is to allow someone to see what the spectral distribution is from a black-body radiator at a given temperature. Programmers can also make use of the Planck distribution functions in the procedure file (wavelength and frequency forms are given).

Slideshow
Last changed: 3 years 34 weeks ago
This Igor experiment takes a folder of images and lets the user manipulate them a little bit and produce slide shows. A web page can be generated, a QuickTime movie made, or the slides can be played in Igor.

XRD Calculator
Last changed: 2 years 9 weeks ago
Overview
This package creates a simulated XRD pattern from a single crystal metal or a binary metal alloy. Base inputs are the cubic structure (SC, FCC, or BCC), lattice parameter, alloy composition, and x-ray wavelength. Output is a vertical lines at appropriate 2-Theta (angle in degrees) for the n=1 and n=2 diffraction lines up to the {333} family of planes, scaled by their hkl diffraction intensities ratios and alloy composition. You can also tag/untag the lines and generate a report to a notebook.
