X-ray Diffraction XRD
Bragg’s law · phase identification · diffraction geometry · detectors · Rietveld refinement
HOW IT WORKS Monochromatic X-rays interact with periodic crystal planes; constructive interference produces peaks at angles governed by Bragg’s law.Scanning Electron Microscopy SEM / EDS

HOW IT WORKS Selected-wavelength light illuminates the powder; an integrating sphere collects diffuse reflectance for optical-response analysis.X-ray Photoelectron Spectroscopy XPS
Photoelectric effect · binding energy · chemical states · surface composition
HOW IT WORKS X-rays eject core-level electrons; their measured kinetic energies are converted to binding energies to identify surface chemical states.Thermal Analysis TGA / DSC / DTA
Mass change · heat flow · thermal events · decomposition and phase transitions
HOW IT WORKS A programmed temperature change is applied while mass or heat-flow/temperature differences are monitored to detect thermal events.
