Crystallography From Wikipedia, the free encyclopedia Jump to: navigation search For the book of poetry, see Crystallography (book) Crystallography (from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and graphein = write) is the experimental science of determining the arrangement of atoms in solids . In older usage, it is the scientific study of crystals Before the development of X-ray diffraction crystallography (see below), the study of crystals was based on the geometry of the crystals. This involves measuring the angles of crystal faces relative to theoretical reference axes ( crystallographic axes ), and establishing the symmetry of the crystal in question. The former is carried out using a goniometer . The position in 3D space of each crystal face is plotted on a stereographic net, e.g. Wulff net or Lambert net . In fact, the pole to each face is plotted on the net. Each point is labelled with its Miller index . The final plot allows the symmetry of the crystal to be established. Crystallographic methods now depend on the analysis of the diffraction patterns that emerge from a sample that is targeted by a beam of some type. The beam is not always

Triclinic Crystal Groups and Classes - Crystallography groups are composed of 32 classes of symmetry derived from observations of the external crystal form. From these 32 classes, 230 space groups (see Crystallography 101 ) are distinguishable using x-ray analysis. For additional information on crystal systems, please review an excellent on-line treatment of this subject, the Introduction to Crystallography and Mineral Crystal Systems by Mike and Darcy Howard. Example Crystal Morphology - To further illustrate these symmetry elements, the example crystalline forms for each symmetry class were constructed using Faces (version 3.7) by Georges Favreau for older browsers and a JAVA language program called JCrystal by Steffen Weber for the java-capable browsers. In addition, Steffen Weber has a new version of JCrystal called KrystalShaper that can produce paper models of the example crystals.

What Is Crystallography? Crystallography is the study of atomic and molecular structure. Scientists in crystallography are called "crystallographers." Crystallographers want to know how the atoms in a material are arranged in order to understand the relationship between atomic structure and properties of these materials. They work in many disciplines, including chemistry, geology, biology, materials science, metallurgy and physics. Crystallographers study diverse substances, from living cells to superconductors, from protein molecules to ceramics. Crystallography began with the study of crystals, like quartz. Today, crystallographers study the atomic architecture of any material that can form an orderly solid - from diamonds to viruses. They also investigate a wide variety of other materials, such as amorphous thin films, membranes, liquid crystals, fibers, glasses, liquids, gases and quasicrystals. Because many crystallographers use x-rays to study crystals, the field is often called "x-ray crystallography." But modern crystallographers use many other methods as well. Atomic force microscopy, neutron diffraction, electron crystallography, molecular modeling, high- and low-temperature studies, high-pressure diffraction and micro-gravity experiments in space are all methods used by crystallographers to unlock the secrets of structure and function.

The lattices can be used to describe the geometrical symmetry of a crystal. The Bravais lattices are sometimes called space lattices. Let's take a look at the two main ways to categorize crystal types. I've described the major crystal structures (e.g., triclinic, hexagonal) and how crystals are classified by their properties (e.g., ionic, covalent) and provided links so that you can see examples of crystal types and learn more about crystallography.

Protein purification Protocols and tips in protein purification or How to purify protein in one day. By S.E.Sedelnikova Protein purification is the first step of almost all in vitro This is not a complete guide to protein purification and you still should to read serious books on theory of chromatography to become familiar with the subject. Introduction General sequence of protein purification procedures "Common sense" strategy in protein purification Protocols ... Charts and Tables Appendixes 2. Protein crystallization The most important part of any protein crystallography studies is protein crystallization. Without perfect crystals of protein (or any other biological samples) it is impossible to carry out any crystallographic structural studies. The aim of protein crystallization is to produce well-ordered protein mono-crystals without any inclusion and large enough to diffract X-Ray beam. You can also find some techniques for low molecular weight peptide crystallization. Despite very wide knowledge about protein crystallization it is still impossible to predict any conditions for protein crystallization. The protein crystallization process is still empiric and the biggest part of success is hidden in the hand and experience of the scientist who performed the protein crystallization and pure luck. So... Read this chapter and don't shy to do the first step in protein crystallography!
