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

Image Gallery John Betts - Fine Minerals Crystallography and Minerals Arranged by Crystal Form Amorphous Isometric Tetragonal Orthorhombic ... 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.

14. X-RAY Crystallography To perform xray crystallography, it is necessary to grow crystals with edges around 0.1-0.3 mm. Crystals are formed as the conditions in a supersaturated http://www.stolaf.edu/people/hansonr/mo/x-ray.html

X-ray Crystallography About the Unit Cell Crystals are three dimensional ordered structures than can be described as a repetition of identical unit cells. The unit cell is made up of the smallest possible volume that when repeated, is representative of the entire crystal. The dimensions of a unit cell can be described with 3 edge lengths (a,b,c) and 3 angles (alpha, beta, gamma). The 3D location of atoms within a unit cell can be listed as their x, y, z Cartesian Coordinates. Space groups describe the symmetry of a unit cell, of which there are 230 variations. In the molecular origami program, by clicking on Use Crystallographic Info NOW , you can experiment with all the different types of space groups. Why are X-rays used ? Using visible light, it will never be possible to see atoms under even the most powerful of microscopes. In order for an object to be seen, its size needs to be at least half the wavelength of the light being used to see it. Since visible light has a wavelength much longer that the distance between atoms it is useless to see molecules. In order to see molecules it is necessary to use a form of electromagnetic radiation with a wavelength on the order of bond lengths, such as X-rays.

English version Schweizerische Gesellschaft für Kristallographie Die Schweizerische Gesellschaft für Kristallographie und ihre Sektion für Kristallwachstum und Materialforschung wurden in Jahr 1968 von Kristallographen, Chemikern, Festkörperphysikern und Mineralogen als gemeinsames Forum für einen wissenschaftlichen interdisziplinären Gedankenautausch gegründet. Sie ist der Schweizerischen Akademie der Naturwissenschaften als wissenschaftliche Fachgesellschaft angegliedert und vertritt die Schweiz in der Internationalen Union für Kristallographie und in der Internationalen Organisation für Kristallzüchtung. Die Gesellschaft organisiert nationale and internationale Konferenzen und Symposien, Gruppenseminare, gezielte Arbeitstagungen und Einzelvorträge an Hochschulen und in Industrielaboratorien. Auch festigt sie ihre Beziehungen mit Schwestergesellschaften in anderen europäischen Ländern durch gemeinsame Tagungen. Auf persönlichen Ebene sind diese Beziehungen schon dadurch gegeben, dass etwa 10% unserer Mitglieder im Ausland tätig sind. Der jährliche persönliche Mitgliedsbeitrag für Gesellschaft und Sektion beträgt SFr. 30.- (SFr. 10.- für Studenten, Diplomanden und Doktoranden). Die Mitglieder erhalten neben den Mitteilungen und Einladungen zu den von uns organisierten Veranstaltungen auch Informationen über bevorstehende ausländische Tagungen, Sommerschulen and Seminare. Durch aktive Anregungen können sie die zukünftige Tätigkeit der Gesellschaft mitbestimmen.
