Introduction to Crystallography: Lecture 2 — Crystals
A series of lectures and handout notes given by Dr. Cora Lind for her Chem 4980/6850/8850: X-ray Crystallography course at the University of Toledo (Ohio). These lectures introduce concepts in crystallography, such as the lattice, symmetry, single-crystal and powder diffraction, crystal structure determination and refinement. This lecture discusses what is a crystal, defines the concept of a unit cell and defines the seven classes of unit cells. Growth of crystals is also discussed. The sharp facets of crystals are determined by the underlying symmetry of the unit cell; these facets are described by Miller indices.

Introduction to Crystallography: Lectures 3 & 4 — Symmetry and Point Groups
Introduction to Crystallography: Lectures 3 & 4 — Symmetry and Point Groups
A series of lectures and handout notes given by Dr. Cora Lind for her Chem 4980/6850/8850: X-ray Crystallography course at the University of Toledo (Ohio). These lectures introduce concepts in crystallography, such as the lattice, symmetry, single-crystal and powder diffraction, crystal structure determination and refinement. Lecture 3 relates the unit cell to the concept of the lattice and introduces the 14 Bravais lattice types. Then point symmetry elements -- the symmetry that can be found in discrete objects are introduced. Lecture 4 expands from symmetry of discrete objects to those of infinitely repeating patterns that fill space. This requires additional types of symmetry elements. Symmetry operations can be combined in a limited number of ways. For discrete objects there are 32 point groups, for infinite objects there are 230 space groups.

Calculation of Crystallographic Texture due to Displacive Transformations in Steels
Calculation of Crystallographic Texture due to Displacive Transformations in Steels
An introduction to the mathematical estimation of the crystallographic texture and microstructure resulting from the displacive transformation of austenite in steels, under the influence of an externally applied system of stresses. It begins with an introduction to the problem, a description of the phenomenological theory of martensite crystallography, and the application of this theory along with a variant selection criterion to determine the texture due to solid-state, displacive transformation. It is demonstrated that there remain difficulties which make a complete closure between theory and experiment unlikely. Progress is needed in relating the chemical and mechanical driving forces for phase transformation to the evolution of overall volume fractions of different crystallographic variants. www.msm.cam.ac.uk

Introduction to Crystallography: Lecture 8 — Structure Factors
A series of lectures and handout notes given by Dr. Cora Lind for her Chem 4980/6850/8850: X-ray Crystallography course at the University of Toledo (Ohio). These lectures introduce concepts in crystallography, such as the lattice, symmetry, single-crystal and powder diffraction, crystal structure determination and refinement. Structure factors provide both intensity and phases for the diffracted beams. This presentation shows how the structure factor equation arises from the positions of atoms in the unit cell. This equation is used to show how systematic absences occur, where classes of reflections are required to have zero intensity by symmetry.

ACTOR sample changing robot for X-ray crystallography
ACTOR, by Rigaku, is complete robotic system for automating routine crystal screening and X-ray diffraction data collection at both synchrotron beam lines and home laboratories. Compatible with almost any goniometer and detector combination, the ACTOR eliminates much of the physical handling of samples required during crystal screening and data collection.
