Crystallography From Wikipedia, the free encyclopedia Jump to: navigation search For the book of poetry, see Crystallography (book) This article includes a list of references , related reading or external links , but its sources remain unclear because it lacks inline citations Please improve this article by introducing more precise citations where appropriate (November 2009) A crystalline solid: atomic resolution image of strontium titanate . Brighter atoms are Sr and darker ones are Ti. Crystallography is the experimental science of determining the arrangement of atoms in solids . The word "crystallography" derives from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and grapho = write. Before the development of X-ray diffraction crystallography (see below), the study of crystals was based on their geometry. 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

X-ray crystallography From Wikipedia, the free encyclopedia Jump to: navigation search X-ray crystallography can locate every atom in a zeolite , an aluminosilicate with many important applications, such as water purification X-ray crystallography is a method of determining the arrangement of atoms within a crystal , in which a beam of X-rays strikes a crystal and diffracts into many specific directions. From the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds , their disorder and various other information. Since many materials can form crystals — such as salts metals minerals semiconductors , as well as various inorganic, organic and biological molecules — X-ray crystallography has been fundamental in the development of many scientific fields. In its first decades of use, this method determined the size of atoms, the lengths and types of chemical bonds, and the atomic-scale differences among various materials, especially minerals and alloys . The method also revealed the structure and functioning of many biological molecules, including vitamins, drugs, proteins and nucleic acids such as

Some are crystals you can grow yourself. Others are representative pictures of crystals of elements and minerals. Bravais Crystal Lattices There are 14 distinct Bravais crystal lattices. 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.

X-Ray Crystallography What are crystals? Crystals are all around us in our everyday lives. Not only can we see crystals in rock formations, but with the aid of a microscope one can see that grains of sugar and salt are great examples of what crystals look like. These types of crystals often have a unique three dimensional shape, called a lattice , that is very strong due to the type of atoms and molecules they are composed of. Although we can not see protein crystals without the help of a special kind of microscope, they too have a unique three dimensional structure. What are proteins? Proteins are one of the most important substances in living organisms. They are composed of chains of amino acids joined by peptide bonds. There are 20 different amino acids and they can appear in any sequence in a protein. Therefore proteins can have many different functions in an organism, and take many different shapes. The fact that there are so many different shaped proteins can make it difficult to determine the structure of a specific protein. Why are scientists interested in protein crystals?

Traditionally, physical models of crystal structures (e.g., "ball and stick" and polyhedral models) have been used to help students better visualize the complex arrangements of atoms within crystalline materials. With the advent of newer computational and graphics technology, computerized virtual modelling of crystal structures and access to large crystal structure databases are now available to supplement traditional tools and methods of crystallographic instruction. We believe that the full potential of crystal structure databases and visualization software for enhancing the teaching of crystallography has not been fully explored. In most mineralogy classes, such tools are used to illustrate concepts in crystallography and crystal-chemistry, but these sessions are mostly controlled by the instructor. The students may or may not have the ability to manipulate the crystal models themselves to more fully interact with the material and form their own learning experiences; such direct interaction with models has been found to effectively aid spatial learning
