X ray crystallography basics explained | x ray diffraction
X ray crystallography basics explained - This lecture explains about the X ray crystallography technique to understand the protein structure. X-ray Crystallography is a scientific method used to determine the arrangement of atoms of a crystalline solid in three dimensional space. This technique takes advantage of the interatomic spacing of most crystalline solids by employing them as a diffraction gradient for x-ray light. This video lecture describes the principles of x ray crystallography and the mechanisms of x ray diffraction studies that gives arise to the crystallographic structure of unknown protein samples.

[Коллоквиум]: Formal Concept Analysis: A Useful Example of Modern Mathematics
Speaker: Bernhard Ganter - Technische Universität Dresden We give impressions of a field of research that was started some 30 years ago under the name of “Formal Concept Analysis.” It is a mathematical theory, based on algebraic structures such as complete lattices, with a spectrum of applications in data analysis and knowledge processing Although the theory is advanced and substantial, it finds more attention in computer science than in mathematics. Indeed, the field has some potential for supporting recent developments of structured knowledge representations. In our lecture, we introduce the very basic notions of the field, show the possibility of expressive graphical representations, discuss some applications and, eventually, demonstrate why the value of this development lies in its mathematical nature.

Powder X-Ray Diffraction (1 out of 2)
Powder X-Ray Diffraction (XRD) allows the determination of crystallographic density and hence crystal structure of unknown crystalline solids. X-rays are diffracted by atoms in a plane and a spherical wave is radiated. If there are two or more such scattering centres, the spherical waves at specific angles reinforce one another (constructive interference) and at other angles cancel one another (destructive interference). A crystal with planes oriented at an angle θ to an incident x-ray beam of wavelength λ will diffract the rays according to Bragg's equation: 2dsinθ = nλ. In video (1 out of 2), the concept of XRD will be illustrated for compound Tungsten which has a BCC structure using planes 110 and 200. In video (2 out of 2), with the Bragg’s angle θ obtained from the Powder XRD Spectrum, the unit cell length and volume and hence the experimental crystallographic density (g/cm3) is calculated. Interplanar distance is also determined. Other molecular animation videos available at http://www.chemistry.nus.edu.sg/educa... - Video Gallery or via the "Animol" app on iOS and Android.

Bragg's Equation, Bragg's Law
For further information about Bragg's Law, Please visit the link given below .... http://vedupro.blogspot.in/2012/12/braggs-law-of-diffraction-define-braggs.html BRAGG'S EQUATION -- BRAGG'S LAW X-rays are electromagnetic radiations with high energies and wavelengths of the order 〖10〗^(-10) meter. These rays can be diffracted whenever they meet barrier with one or more openings that is about the same size as the wavelength. The layers of atoms or ions in crystals are separated by a distance of around 100 or 200 pm, which is the right range to cause X-rays to be diffracted. Thus layers of atoms in a crystal act as a diffracting for X-rays.

How-to: Visualise crystal morphology using Mercury
A 'how-to' video on visualising crystal morphology using Mercury. For some structures you may be interested in the physical shape of the crystal and the relationship between this shape and the structure at the molecular level. You can predict the shape of the crystal itself using the BFDH morphology option. Here each of the crystal faces is indexed and we can explore the packing of the structure as normal. If you have experimentally determined the crystal shape (by "face indexing") you may want to read in this information for display in Mercury. You can do this by opening the BFDH morphology dialogue and clicking on Open, then reading in your morphology file. --- Produced by Andrew Bennett (a student at Dame Alice Owen's School, Potters Bar) during a work experience placement at CCDC. --- Mercury - Crystal Structure Visualisation, Exploration and Analysis Made Easy Mercury offers a comprehensive range of tools for structure visualisation, the exploration of crystal packing and statistical analysis of ConQuest geometric searches. http://www.ccdc.cam.ac.uk/

Bragg Lecture 2001. X-ray crystal structure analysis and Manchester (complete)
Since its origins 150 years ago the University of Manchester has had many famous staff and students in the history of science including a variety of Nobel Laureates. The University had a significant involvement in the development of science at the global level and included Ernest Rutherford’s 'splitting of the atom'. W. L. Bragg succeeded Rutherford both in Manchester and in Cambridge and Bragg in his 18 years in Manchester contributed a major part of that science history. Bragg’s scientific interests embraced crystallographic methods, strongly based on physical optics, and their applications in chemistry and biology, the latter during his Cambridge ie final part of his career. A Publc Lecture was given by Professor John R. Helliwell as the 'W. L. Bragg Lecture', delivered at the University of Manchester’s Physics Department ('Schuster Laboratory'), on 5th February 2001 as part of the University’s 150th Anniversary Celebration. A detailed article was prepared for the Manchester Literary and Philosophical Society Memoirs and subsequently was reproduced in Z. Krist., with permission of the Society, as a contribution to Z. Krist’s 125th Anniversary.

The diffraction pattern of a protein crystal
2014 is the international year of crystallography, the one hundredth anniversary of great achievements in crystallography. Max Theodor Felix von Laue was awarded the Nobel prize in physics in 1914 for his discovery of the diffraction of X-rays by crystals. In 1915, sir William Henry Bragg and William Lawrence Bragg won the Nobel prize for their services in the analysis of crystal structure by means of X-rays.Thanks to many crystallographers including Laue and Braggs, now we can investigate the detailed atomic structures of a number of minerals, chemicals, biomolecules, and whatever forms a crystal. Here, the diffraction pattern of a protein crystal is shown. Protein crystallography has been applied to studying living systems and discovering new drugs. Undoubtedly, crystals look beautiful. And so do diffraction patterns from crystals.

Hexagonal Closed Packed Structure 3D Animation
Closest-Packed Structures Efficient Packing of Balls Suppose you are given a large number of tennis balls and asked to pack them together in the most efficient fashion. What is the most efficient packing strategy? One could toss all the balls together in a box and shack the box to induce the balls to settle. The resulting packing of the balls is called a random closest-packed structure. Not surprisingly it is not the most efficient way to pack the tennis balls. Although there are a variety of factors that influence how atoms pack together in crystals, atoms generally seek the most efficient packing structure in order to maximumize intermolecular attractions. Metals provide the simplest packing case, because these atoms can generally be regarded as uniform spheres. The two most efficient packing arrangements are the hexagonal closest-packed structure (hcp) and the cubic closest-packed structure (ccp). This exercise focuses on the hexagonal closest-packed structure, and the next exercise deals with the cubic closest-packed structure. In a crystal the atoms are arranged in a regular repeating pattern. The smallest repeating unit is called the unit cell. The entire structure can be reconstructed from knowledge of the unit cell. The unit cell is characterized by three lengths and three angles. The quantities a and b are the lengths of the sides of the base of the cell and γ is the angle between these two sides. The quantity c is the height of the unit cell. The angles α and β describe the angles between the base and the vertical sides of the unit cell. In the hexagonal closest-packed structure, a = b = 2r and c = 4(2/3)1/2 r, where r is the atomic radius of the atom. The sides of the unit cell are perpendicular to the base, thus α = β = 90o. The base has a diamond (hexagonal) shape corresponding with γ = 120o. How might one characterize the efficiency of the packing of atoms in a crystal? The volume of the unit cell is readily calculated from knowledge of a, b, c, α, β, and γ. The volume of the hexagonal unit cell, which described the hexagonal closest-packed structure, is V = 8(2)1/2 r3. The volume of an individual atom is Va = 4 π r3/3 and there are two atoms in the unit cell for the hexagonal closest-packed structure, thus the volume occupied by the atoms is 2 Va = 8 π r3/3. The packing efficiency, f, is the fraction of the volume of the unit cell actually occupied by atoms. For the hexagonal closest-packed structure f = π/(18)1/2 = 74.05%. The cubic closest-packed structure has the same packing efficiency, and this value is the highest efficiency that can be achieved. Hexagonal Closest-Packed Structure The virtual reality display illustrates the packing of atoms in the cubic closest-packed structure. This display requires Java3D. If the display is not visible, consult the Java3D FAQ. Drag with the left mouse button to rotate, the center button to zoom, and the right button to move the object. Follow the suggested steps to visualized the structure, which consist of a 4x4x4 array of 64 atoms. All of the atoms are identical; however, the atoms have been colored red and green to illustrate which rows have an identical position in the xy plane. The layers of atoms in the hexagonal closest-packed structure follow an ABABAB pattern. Use the "+" button to start adding atoms in the first layer. Before adding each atom, think about the best location for each atom to achieve the most efficient packing (there are multiple positions). Pay special attention to how adjacent rows are positioned. After the first layer is complete, use the "+" button to add atoms to the second layer. Before adding the first atom, think about the best position in which to place the atom. After the second layer is complete, use the "+" button to add atoms to the third layer. Before adding the first atom, carefully examine the completed layers. Notice that there are two different positions to place the first atom in the third layer. In the hexagonal closest-packed structure, the third layer lies directly above the first layer. Remove all atoms. Display the unit cell and the lattice positions. (Each atoms is centered on a lattice position.) Add atoms to each layer and observe the arrangement of atoms in the unit cell.
