Download or read book Direct Methods for Solving Macromolecular Structures written by S. Fortier and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of the proceedings of the 1997 NATO Advanced Study Institute (ASI) on Direct Methods for Solving Macromolecular Structures was assembled from the lecturers' contributions and represents a comprehensive and in-depth overview of crystallographic structure determination methods for macromolecules. While having a focus based on the direct methods, the Institute adopted an inclusive and broad perspective. Thus, both direct and experimental phasing techniques are presented in this book, highlighting their complementarities and synergies. As weil, methodologies spanning the full crystallographic image reconstruction process - from low resolution envelope definition to high resolution atomic refinement- are discussed. The first part of the book introduces the array of tools currently used in structure determination, whether originating from a mathematical, computational or experimental framework. This section of the book displays the variety and ingenuity of old and new phasing approaches developed to solve increasingly complex structures. Some of the contributions focus on recent developments and/or implementations that have given older approaches a new life. A case in point is the re-implementation of Buerger's superposition approach, which is now solving protein structures. Another beautiful example is found in the introduction to the traditional multiple isomorphous replacement approach where new techniques, such as site-directed mutagenesis and the use of inert gases in the preparation of heavy atom derivatives, are described. Equally impressive are the presentations of newer approaches, which take advantage of advances on the experimental front (e. g.
Download or read book The Fundamentals of Imaging written by M. M. Woolfson and published by World Scientific. This book was released on 2014-05-14 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is through images that we understand the form and function of material objects, from the fundamental particles that are the constituents of matter to galaxies that are the constituents of the Universe. Imaging must be thought of in a flexible way as varying from just the detection of objects OCo a blip on a screen representing an aircraft or a vapour trail representing the passage of an exotic particle OCo to displaying the fine detail in the eye of an insect or the arrangement of atoms within or on the surface of a solid. The range of imaging tools, both in the type of wave phenomena used and in the devices that utilize them, is vast. This book will illustrate this range, with wave phenomena covering the entire electromagnetic spectrum and ultrasound, and devices that vary from those that just detect the presence of objects to those that image objects in exquisite detail. The word OCyfundamentalsOCO in the title has meaning for this book. There will be no attempt to delve into the fine technical details of the construction of specific devices but rather the book aims to give an understanding of the principles behind the imaging process and a general account of how those principles are utilized.
Download or read book Structure Determination by X ray Crystallography written by Mark Ladd and published by Springer Science & Business Media. This book was released on 2014-07-08 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advances in and applications of x-ray and neutron crystallography form the essence of this new edition of this classic textbook, while maintaining the overall plan of the book that has been well received in the academic community since the first edition in 1977. X-ray crystallography is a universal tool for studying molecular structure, and the complementary nature of neutron diffraction crystallography permits the location of atomic species in crystals which are not easily revealed by X-ray techniques alone, such as hydrogen atoms or other light atoms in the presence of heavier atoms. Thus, a chapter discussing the practice of neutron diffraction techniques, with examples, broadens the scope of the text in a highly desirable way. As with previous editions, the book contains problems to illustrate the work of each chapter, and detailed solutions are provided. Mathematical procedures related to the material of the main body of the book are not discussed in detail, but are quoted where needed with references to standard mathematical texts. To address the computational aspect of crystallography, the suite of computer programs from the fourth edition has been revised and expanded. The programs enable the reader to participate fully in many of the aspects of x-ray crystallography discussed in the book. In particular, the program system XRAY* is interactive, and enables the reader to follow through, at the monitor screen, the computational techniques involved in single-crystal structure determination, albeit in two dimensions, with the data sets provided. Exercises for students can be found in the book, and solutions are available to instructors.

Download or read book Outline of Crystallography for Biologists written by David Blow and published by OUP Oxford. This book was released on 2002-04-11 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Outline of Crystallography for Biologists is intended for researchers and students in the biological sciences who require an insight into the methods of X-ray crystallography without needing to learn all the relevant theory. The main text is purely descriptive and is readable by those with minimal mathematical knowledge. Some mathematical detail is given throughout in boxes, but these can be ignored. Theory is limited to the essentials required to comprehend issues of quality. There is an extensive reference section and suggestions for further reading for those who wish to delve deeper. The first part 'Fundamentals' presents the underlying ideas which allow x-ray structure analysis to be carried out and provides an appropriate background to courses in structural determination. The second part 'Practice' gives more information about the procedures employed in the course of crystal structure determination. The emphasis is on the quality measures of X-ray diffraction analysis to give the reader a critical insight into the quality and accuracy of a structure determination and to enable the reader to appreciate which parts of a structure determination may have caused special difficulty. There is no pretence of completeness and many matters discussed in standard crystallography texts are deliberately omitted. However, issues not brought out in the standard texts are discussed, making it a useful resource for non-practising crystallographers as well.

Download or read book Unified Theory and Practice written by Frank H. Chung, PhD and published by Dorrance Publishing. This book was released on 2020-01-20 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unified Theory and Practice: Polymer Adhesion, X-Ray Diffraction, & X-Ray Florescence By: Frank H. Chung, PhD There are seven adhesion theories scattered in the literature. Each explains adhesion strength loosely in words and figures. The unified theory of polymer adhesion derives a mathematical equation linking bond length, bond energy and bond strength (lb/in 2 ). It unifies and clarifies prior insights into a coherent concept. A set of guidelines is compiled on the effects of functional groups, solvent blends, pigments and filler, adhesion promotion, and the causes of adhesion loss. Due to the complex matrix effects, the quantitative XRD & XRF analyses of mixtures require calibration lines from standard, hence tedious and time-consuming. New insights reveal that both the matrix effects and calibration lines can be eliminated mathematically. A decoding formula applies to both XRD & XRF. One XRD or XRF scan quantifies the chemical elements or compounds in any mixture. The unified procedure reduces about 80% of work current practice with a precision of ± 5% or better.
Download or read book Transmission Electron Microscopy written by C. Barry Carter and published by Springer. This book was released on 2016-08-24 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is a companion volume to Transmission Electron Microscopy: A Textbook for Materials Science by Williams and Carter. The aim is to extend the discussion of certain topics that are either rapidly changing at this time or that would benefit from more detailed discussion than space allowed in the primary text. World-renowned researchers have contributed chapters in their area of expertise, and the editors have carefully prepared these chapters to provide a uniform tone and treatment for this exciting material. The book features an unparalleled collection of color figures showcasing the quality and variety of chemical data that can be obtained from today’s instruments, as well as key pitfalls to avoid. As with the previous TEM text, each chapter contains two sets of questions, one for self assessment and a second more suitable for homework assignments. Throughout the book, the style follows that of Williams & Carter even when the subject matter becomes challenging—the aim is always to make the topic understandable by first-year graduate students and others who are working in the field of Materials Science Topics covered include sources, in-situ experiments, electron diffraction, Digital Micrograph, waves and holography, focal-series reconstruction and direct methods, STEM and tomography, energy-filtered TEM (EFTEM) imaging, and spectrum imaging. The range and depth of material makes this companion volume essential reading for the budding microscopist and a key reference for practicing researchers using these and related techniques.
Download or read book Combined Analysis written by Daniel Chateigner and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces and details the key facets of Combined Analysis—an x-ray and/or neutron scattering methodology which combines structural, textural, stress, microstructural, phase, layer, or other relevant variable or property analyses in a single approach. The author starts with basic theories related to diffraction by polycrystals and some of the most common combined analysis instrumental set-ups are detailed. Powder diffraction data treatment is introduced and in particular, the Rietveld analysis is discussed. The book also addresses automatic phase indexing—a necessary step to solve a structure ab initio. Since its effect prevails on real samples where textures are often stabilized, quantitative texture analysis is also detailed. Also discussed are microstructures of powder diffraction profiles; quantitative phase analysis from the Rietveld analysis; residual stress analysis for isotropic and anisotropic materials; specular x-ray reflectivity, and the various associated models. Finally, the book introduces the combined analysis concept, showing how it is superior to the view presented when we look at only one part of the analyses. This book shows that the existence of texture in a specimen can be envisaged as a way to decouple ordinarily strongly correlated parameters, as measured for instance in powder diagrams, and to examine and detail deeper material characterizations in a single methodology.
