DetectFlashVer = 0; This page requires the latest version of the Adobe Flash Player. Get Flash Now To Home Page B y the time you finish with this chapter, it will become apparent to you that one of us is a quiltmaker. So I will confess right up front that I am the guilty party. My interest in quiltmaking really began before birth, because my mother was working on a king-size quilt when I was in utero. Sometime just before I left for college, the quilt-making bug bit me really hard, and I could be found in all my spare time with a pile of fabric squares on my lap and a needle in my hand. I have never been a person who could sit still easily! While I was in graduate school, I satisfied my artistic urges by studying painting three mornings a week at nearby Wellesley College, which I had attended as an undergraduate. It was a relief to escape the relentless pace of M.I.T. for a few hours, and to use the other half of my brain (while enjoying the company of women, a rare treat for me in those days). Looking back on it, I should not be surprised that the things I painted ended up being rather geometrical; my artistic expressions involved shape, color, and pattern. When I moved to Pasadena and then on to Oregon, I returned to quilt making, applying the lessons I learned from oil and acrylics to the medium of fabric. Now I make art quilts in my free time (what little free time I have!); hopefully someday I will find the time to exhibit them in shows.

Links International Union of Crystallography Commission on Inorganic and Mineral Structures Approved by action of the IUCr General Assembly , 8 August 2002 The IUCr-CIMS was founded to promote and achieve the following aims: To strengthen links and interactions among mineral, inorganic and materials scientists and between these scientists and the crystallographic community. To promote the presence at the IUCr meetings of scientists working in 'inorganic-crystallographic' and 'geoscience- crystallographic' institutions. To present at the same meetings common aspects of the inorganic structures independently from their natural or synthetic origin. To favour the historical influence that mineral structures have played on developing inorganic materials of technological interest. To promote and encourage the publication of inorganic and mineralogical papers in the Journals of the Union. To promote the development and dissemination of methods, computing programs and databases of interest for the inorganic crystallographic community.

Classically, the optical properties of crystals were of value in mineralogy and chemistry for the identification of substances. Modern crystallography is largely based on the analysis of the diffraction of X-rays by crystals acting as optical gratings. Using X-ray crystallography, chemists are able to determine the internal structures and bonding arrangements of minerals and molecules, including the structures of large complex molecules such as proteins and DNA.

Protein Crystallography Course Course Homepage Basic: Advanced: Overview of macromolecular X-ray crystallography Outline Methods to study 3D structure Principles of X-ray crystallography Fitting and refinement Validation This series will cover the theory and practice of X-ray crystallography, particularly as it applies to studying the three-dimensional structure of macromolecules. The notes will often refer specifically to proteins, but generally the same techniques and problems apply to other macromolecules (DNA, RNA) or assemblies (viruses, ribosomes). If you've gotten this far you probably have a good idea why we want to study the 3D structure of molecules. 3D structure allows us to understand biological processes at the most basic level: which molecules interact, how they interact, how enzymes catalyse reactions, how drugs act. In some cases, it can allow us to understand disease at an atomic level, such as the sickling of red blood cells. We can also exploit 3D structure in developing new drugs. There are a number of methods for studying 3D structure, outlined briefly in the next section. But we will concentrate on X-ray crystallography, which is arguably the most effective of these techniques at present. Certainly the other techniques complement crystallography and have a valued place in the set of tools that we use.

University of Oxford chem cryst news July 2010 CRYSTALS Version 14.11 is available as a beta-test. Collaboration with Ernesto Mesto (Dipartimento Geomineralogico - Universitŕ degli Studi di Bari) uncovered over-sights in the original 1979 code, which lost contributions when a twin component fell onto a centring absence. Difference maps with twinned data now seem to reveal hydrogen atoms very reliably. December 09 CRYSTALS Version 14.03 is available as a beta-test. This version has involved a major tidy-out of the SCRIPTS. There are 476 of them, plus associated data files, so that there is a real chance that something has been broken. If a required script has been inadvertently removed, you should get a plain-language message asking you to contact Oxford. The changes made by Richard Cooper to the GUI drivers seem to be working well, giving very good performance with modern graphics cards. Input of reflection data from various sources in now handled uniformly. cif import of basic data (.cif) and reflection data (.fcf) has been improved. Restrained refined optimisation of Hydrogen atoms is now standard in model building, and can be invoked at any time. Riding refinement remains standard for the final stages to satisfy IUCr observation:parameter ratios.

75. Bond Valence Wizard Software A program for prediction of interatomic distances in crystal structures. http://orlov.ch/bondval/

This piece of software is to predict bond distances in crystals. It helps to verify structure solutions, but also in more challenging tasks such as locating lattice-induced strains (cf. 'Method in detail' below). To begin you will pick up atoms forming your structure from Table of Elements and define number of bonds between them. The program uses Bond Valence Method (BVM, also known as I.D.Brown method) based on empirical [bond valence]-[bond length] relations and modified second Pauling rule, demanding a local balance of valences. More about underlying principles: I.D.Brown, Acta Cryst. B33 (1977) 1305-1310 (PDF, 0.6 Mb) See also topic Method in Detail Operating system requirements Microsoft Windows 3.11 and later.

Home Awards Conference Membership ... Support The 68th Annual Pittsburgh Diffraction Conference will be held from October 27th - 29th, 2010 at the Holiday Inn University Center, Pittsburgh, PA. The Sidhu Award for Outstanding Contributions to the Fields of Crystallography or Diffraction by a Scientist within Six Years of Her / His Ph.D. Welcome to our Website The Pittsburgh Diffraction Society (PDS) is a not-for-profit organization which promotes fundamental and applied diffraction and crystallographic research and the exchange of ideas and information concerning such research. The PDS was founded by Professor Surain S. Sidhu who organized the first Pittsburgh Diffraction Conference in 1943. Since that time the PDS has sponsored an annual conference which is held in Pittsburgh, Pennsylvania every other year. Professor Sidhu is remembered and honored through the Sidhu Award , given to an outstanding scientist who is within six years of having earned the Ph.D. or its equivalent. Other awards sponsored by the PDS to support and encourage young scientists include the George Jeffrey Award , which provides travel assistance for students attending the triennial Congress of the International Union of Crystallography, and the Chung Soo Yoo Award given to the best student presenter at the annual Pittsburgh Diffraction Conference.
