THE WORKBENCH / FRAMEWORKED

Scientific
tools.

Calculators and interactive resources for exploring measurements, models, and the evidence behind scientific conclusions.

TOOL NO. 001FIG 01 — PEAK WIDTH / SCHERRER EQUATION

PXRD ANALYSIS / RESEARCH BETA

Scherrer
calculator.

Upload a powder diffraction pattern, fit individual reflections, inspect their full widths at half maximum, and estimate coherent crystallite domain sizes.

XY and XYE text files
Automatic suggestions and manual peak selection
Visible assumptions and downloadable results

TOOL NO. 002 / DIFFRACTION EDUCATION

Bragg's law explorer.

See how the spacing of crystal lattice planes determines a possible diffraction angle. Change a square lattice, compare (10) and (11) planes, then examine the Bragg ray construction.

Explore Bragg's law

TOOL NO. 003 / GENERAL CHEMISTRY

Reagent ratio calculator.

Set molar equivalents for two or more reagents, enter one known mass or amount, and calculate the remaining quantities. Includes color-coded results, multiple reagents, and easy copying.

Calculate reagent ratios

Molecular vibration explorer.

Predict how an isotope swap shifts an infrared absorption band, then test your answer against the quantum energy levels.

Explore molecular vibration

Explore metal–organic frameworks.
