Book excerpt: This dissertation describes a set of experiments loosely unified under the general theme of 3D electron crystallography. Chapter 1 provides a comprehensive overview of the scientific literature in the field, with particular emphasis on experiments aimed at using electron diffraction to elucidate the atomic structure of three-dimensional molecular crystals. Chapter 2 focuses on the development of a publicly accessible web server, FAES (Factors of Atomic Electron Scattering, httpss://srv.mbi.ucla.edu/faes), containing a database of electron scattering factors parameterized into Gaussian approximations compatible with widely used least-squares refinement programs. These include all neutral and ionic species tabulated in the International Tables for Crystallography, as well as fractionally charged scattering factors calculated by computing linearly weighted sums of adjacent integral neighbors. FAES provides numerical fitting coefficients, statistical goodness-of-fit values, and elastic and estimated inelastic cross-sections at a range of accelerating voltages relevant to transmission electron microscopy. Chapter 3 details rigorous studies involving the mapping of electron beam-induced radiolytic damage in molecular crystals using 4D scanning transmission electron microscopy (4D-STEM), conducted on a variety of organic and organometallic species spanning a wide gamut of chemical space. By acquiring a series of consecutive 4D-STEM scans on the same crystal, we explicitly visualize the spatial evolution of coherently diffracting zones (CDZs) as a function of accumulating electron fluence, providing a detailed, time-resolved map of the internal lattice reorientation induced by radiolysis. These experiments also unveil the resolution-dependent propagation of tides of amorphization from impact craters created by asymmetric, localized delivery of incident electrons. Chapter 4 relates the development of the 4D-STEM method nanobeam electron diffraction tomography into a technique capable of overcoming obstacles that thwart structural elucidation by conventional microcrystal electron diffraction (microED). 4D-STEM's unique ability to pinpoint a specific nanoscale volume for data analysis enables pixel-by-pixel spatial exclusion of unwanted signal from disordered or Bragg-silent regions, empowering us to simply pick and choose whichever CDZs generate the highest-quality diffraction patterns. These experiments represent the first 4D-STEM structures phased ab initio by direct methods.

Book Synopsis Electron Crystallography by : Thomas E. Weirich
Download or read book Electron Crystallography written by Thomas E. Weirich and published by Springer Science & Business Media. This book was released on 2006-08-18 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade we have been witness to several exciting achievements in electron crystallography. This includes structural and charge density studies on organic molecules complicated inorganic and metallic materials in the amorphous, nano-, meso- and quasi-crystalline state and also development of new software, tailor-made for the special needs of electron crystallography. Moreover, these developments have been accompanied by a now available new generation of computer controlled electron microscopes equipped with high-coherent field-emission sources, cryo-specimen holders, ultra-fast CCD cameras, imaging plates, energy filters and even correctors for electron optical distortions. Thus, a fast and semi-automatic data acquisition from small sample areas, similar to what we today know from imaging plates diffraction systems in X-ray crystallography, can be envisioned for the very near future. This progress clearly shows that the contribution of electron crystallography is quite unique, as it enables to reveal the intimate structure of samples with high accuracy but on much smaller samples than have ever been investigated by X-ray diffraction. As a tribute to these tremendous recent achievements, this NATO Advanced Study Institute was devoted to the novel approaches of electron crystallography for structure determination of nanosized materials.
Book Synopsis Electron Crystallography by : D. Dorset
Download or read book Electron Crystallography written by D. Dorset and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: The re-emergent field of quantitative electron crystallography is described by some of its most eminent practitioners. They describe the theoretical framework for electron scattering, specimen preparation, experimental techniques for optimum data collection, the methodology of structure analysis and refinement, and a range of applications to inorganic materials (including minerals), linear polymers, small organic molecules (including those used in nonlinear optical devices), incommensurately modulated structures (including superconductors), alloys, and integral membrane proteins. The connection between electron crystallography and X-ray crystallography is clearly defined, especially in the utilisation of the latest methods for direct determination of crystallographic phases, as well as the unique role of image analysis of high-resolution electron micrographs for phase determination. Even the aspect of multiple beam dynamic diffraction (once dreaded because it was thought to preclude ab initio analysis) is considered as a beneficial aid for symmetry determination as well as the elucidation of crystallographic phases, and as a criterion for monitoring the progress of structure refinement. Whereas other texts have hitherto preferentially dealt with the analysis of electron diffraction and image data from thin organic materials, this work discusses - with considerable optimism - the prospects of looking at `harder' materials, composed of heavier atoms. Audience: Could be used with profit as a graduate-level course on electron crystallography. Researchers in the area will find a statement of current progress in the field.
Book Synopsis Uniting Electron Crystallography and Powder Diffraction by : Ute Kolb
Download or read book Uniting Electron Crystallography and Powder Diffraction written by Ute Kolb and published by Springer. This book was released on 2012-12-20 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The polycrystalline and nanocrystalline states play an increasingly important role in exploiting the properties of materials, encompassing applications as diverse as pharmaceuticals, catalysts, solar cells and energy storage. A knowledge of the three-dimensional atomic and molecular structure of materials is essential for understanding and controlling their properties, yet traditional single-crystal X-ray diffraction methods lose their power when only polycrystalline and nanocrystalline samples are available. It is here that powder diffraction and single-crystal electron diffraction techniques take over, substantially extending the range of applicability of the crystallographic principles of structure determination. This volume, a collection of teaching contributions presented at the Crystallographic Course in Erice in 2011, clearly describes the fundamentals and the state-of-the-art of powder diffraction and electron diffraction methods in materials characterisation, encompassing a diverse range of disciplines and materials stretching from archeometry to zeolites. As such, it is a comprehensive and valuable resource for those wishing to gain an understanding of the broad applicability of these two rapidly developing fields.

Book Synopsis Fibrous Proteins: Structures and Mechanisms by : David A.D. Parry
Download or read book Fibrous Proteins: Structures and Mechanisms written by David A.D. Parry and published by Springer. This book was released on 2017-01-18 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the readers with an up-to-date review of the design, structure and function of a representative selection of fibrous proteins in both health and disease. The importance of the α-helical coiled coil, a conformational motif based on the heptad repeat in the amino acid sequence of all α-fibrous proteins (and parts of some globular proteins) is underlined by three Chapters devoted to its design, structure, function and topology. Specific proteins covered in the text and which depend on the coiled coil for their structure and function, include the intermediate filament proteins, tropomyosin, myosin, paramyosin, fibrin and members of the spectrin superfamily. Also described are fibrous proteins based on the β-pleated sheet and collagen conformations. Recombinant structural proteins, especially of silk and collagen, are discussed in the context of developing new biomaterials with varied applications. Established researchers and postgraduate students in the fields of protein chemistry, biochemistry and structural biophysics will find Fibrous Proteins: Structures and Mechanisms to be an invaluable collection of topical reviews that describe the basic advances made in the field of fibrous proteins over the past decade. This book, written by recognized authorities in the field, provides a clear account of the current status of fibrous protein research and, in addition, establishes the basis for deciding the most appropriate directions for future activity, including the applications of protein engineering and the commercial exploitation of new biomaterials.

Book Synopsis Structural Insights Into Gene Expression And Protein Synthesis by : Thomas A Steitz
Download or read book Structural Insights Into Gene Expression And Protein Synthesis written by Thomas A Steitz and published by World Scientific. This book was released on 2020-08-18 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several years ago, Thomas Steitz agreed to contribute a volume to the 'World Scientific Series in Structural Biology' that would deal with the contributions he and his coworkers have made to structural biology during his remarkable career. Sadly, Tom died in the fall of 2018 before he had had time to do more than produce an outline for this book, and a list of the reprints he wanted it to contain.Fortunately, Tom's colleagues and coworkers responded enthusiastically when they were informed later that fall that if they were willing to help out, a volume would be published to commemorate his career. It fell to Anders Liljas, Peggy Eatherton, Tom's longtime administrative assistant, and Peter Moore, a close colleague, to oversee their efforts. Thomas Steitz is best known for the work he and his coworkers did to elucidate the biochemical basis of gene expression. The structures of a large number of the macromolecules involved in transcription and translation emerged from his laboratory over the course of his career. This book includes reprints of the most important papers he had published, grouped according to the structures they relate to, and commentaries written by the scientists who collaborated with him to solve each of them. It thus summarizes the achievements of one of the most distinguished biochemists of the second half of the 20th century.
Book Synopsis Single-particle Cryo-electron Microscopy by : Joachim Frank
Download or read book Single-particle Cryo-electron Microscopy written by Joachim Frank and published by World Scientific Publishing Company. This book was released on 2017-12-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book reproduces 55 of more than 300 articles written by the author, representing milestones in methods development of single-particle cryo-EM as well as important results obtained by this technique in the study of biological macromolecules and their interactions. Importantly, neither symmetries nor ordered arrangements (as in two-dimensional crystals, helical assemblies, icosahedral viruses) are required. Although the biological applications are mainly in the area of ribosome structure and function, the elucidation of membrane channel structures and their activation and gating mechanisms are represented, as well. The book is introduced by a commentary that explains the original development of concepts, describes the contributions of the author's colleagues and students, and shows how challenges were overcome as the technique matured. Along the way, the ribosome served as an example for a macromolecule with intricate structure and conformational dynamics that pose challenges for three-dimensional visualization. Toward the end of the book -- bringing us to the present time -- molecular structures with near-atomic resolution are presented, and a novel type of computational analysis, manifold embedding, is introduced. Single-particle cryo-EM is currently revolutionizing structural biology, presenting a powerful alternative to X-ray crystallography as a means to solve the structure of biological macromolecules. The book presents in one place a number of articles containing key advances in mathematical and computational methods leading up to the present time. Secondly, the development of the technique over the years is reflected by ever-expanding discoveries in the field of ribosome structure and function. Thirdly, as all histories of ideas, the history of concepts pertaining to this new method of visualization is fascinating all in itself.
