Anomalous small angle scattering
Quarterly Reviews of Biophysics, 1981Isomorphous replacement methods have been revolutionary in macromolecular structure research. This has been most clearly demonstrated in protein crystallography. Specific binding of heavy atoms to protein molecules in the crystalline state provides the necessary reference for the phase determination of each Bragg reflexion and opens the way to the ...

Small-angle scattering by dislocations
Acta Crystallographica Section A Foundations of Crystallography, 1999It is shown that the small-angle scattering of X-rays or neutrons by dislocations within a deformed metal, which are partially ordered into wall-like structures, is characterized by several factors. Principally these are associated with: (i) a single dislocation or dipole; (ii) the dislocation configuration in the plane of the wall; and (iii) the ...

Small-angle scattering from molten salts
Philosophical Magazine B, 1979Abstract The partial structure factors S++, S+- and 5−in molten salts are considered at small wavenumber k and the following results are established : (i) the term of order k2 in S++ - S– is determined by the difference in partial volumes of the two ionic species; (ii) a term of order k3 arises in the Sys from the presence of van der Waals dipole ...

Small-angle neutron scattering
2000Abstract Small-angle scattering (SAS) of X-rays or neutrons arises from scattering density fluctuations of the order 10—100 A. In biological studies, samples are usually solutions of macromolecules in this size range. Depending on the experimental conditions such as macromolecular concentration, for example, SAS provides information on ...

Small-Angle Neutron Scattering
2016Recent progress on materials for hydrogen storage have pointed out that kinetics and thermodynamics can be modified by nano-confinement of hydrides in porous scaffolds. The investigation of the structural features of these particular systems is challenging with conventional methods, for instance due to the lack of peaks in the diffraction pattern ...

Small-angle neutron scattering
2009Abstract The theory and practice of small-angle X-ray scattering (SAXS) dates back to the 1930s and is well described in the classic book of Guinier and Fournet (1955). Small-angle neutron scattering (SANS) came much later. It was not until the early 1970s, when position-sensitive detectors on cold neutron guides became available, that ...

Small-angle neutron scattering
2006The use of small-angle neutron scattering (SANS) for the study of biological macromolecules is described. Topics covered in this chapter include: the theoretical basis of SANS; contrast variation; and the measurement of distances between chemically specified points in a macromolecule or macromolecular complex. Practical considerations are addressed and

Small-Angle Neutron Scattering
1997Small-angle neutron scattering (SANS) experiments from networks were initiated by Benoit and collaborators in the mid-1970s. Currently, SANS is an important major technique used in studying network structure and behavior. Its importance lies in its being a direct method with which observations may be made at the molecular-length scale without the need ...

Biological Small Angle Scattering
2018The technique of small angle solution scattering has been revolutionized in the last two decades. Exponential increases in computing power, parallel algorithm development, and the development of synchrotron, free-electron X-ray sources, and neutron sources, have combined to allow new classes of studies for biological specimens.
