What Can You Do with XRD? Identify and Quantify Phase Composition TiO 2 - Rutile TiO 2 - Anatase TiO 2 - Brookite Rutile: P4 2 /mnm high temperature polymorph white pigment, sunscreen, UV-blocking coatings, photovoltaic Anatase: I4 1 /amd semiconductor, photocatalyst, antimicrobial coating, oxygen sensor Brookite: Pcab no known use

Other Things to Do with XRD Data  Measure Unit Cell Lattice Parameters  Estimate Crystallite Size and Microstrain  Measure Residual Stress (macrostrain)  Measure Texture or Epitaxy  Evaluate Thin Film Quality  Determine Crystal Orientation  Determine Crystal Structure

Diffraction Techniques Available at the CMSE  X-Ray Powder Diffraction (XRPD)  Grazing Incidence Angle Diffraction (GIXD)  Pole Figure Mapping  Microdiffraction (  XRD)  Residual Stress Mapping  In situ XRD from 11K to 1473 K  Reciprocal Space Mapping  Single Crystal Diffraction (SCD)  Back-Reflection Laue  X-Ray Reflectivity (XRR)  Small Angle X-Ray Scattering (SAXS)

Getting Access to XRD  Training for Self-Use Requires  1 hour X-ray Safety Course from EHS  1 hour Lab Specific Safety Training  2 hr Instrument Specific Training  2 hr Practical XRD Lecture  next session: June 21, 10 am to 5 pm

Getting Access to XRD  Also Recommended for Self-Users:  Basic XRD Data Analysis using Jade software  1:30 to 4 pm on June 26 or June 27  additional dates scheduled according to demand  Assisted Use is also Available  usually needs to be scheduled ~2 weeks in advance
