Synopsis: An X-ray compatible microfluidic platform for protein crystallization facilitates in situ Laue diffraction in serial crystallography.
Synopsis: The SHADE webserver http://shade.ki.ku.dk has been updated to allow the use of ab-initio calculations and experimental information. The resulting hydrogen ADPs are compared to neutron structures and other estimation approaches.
Synopsis: A detailed comparison of single crystal diffraction data collected with Ag K and Mo K microsources (IS) indicates that the Ag K data are better when absorption is significant. Empirical corrections intended to correct for absorption also correct well for the effects of the highly focused IS beams.
Synopsis: A computer program to assist in visualizing and characterizing solvent channels in macromolecular crystals is described.
Synopsis: Single- and multi-crystal data collection strategy and automated data processing have been tightly integrated into the JBluIce graphical user interface. Grid Engine is used to distribute these processes into multiple workstations to make efficient use of all available computing resources.
Synopsis: A methodology to use a laboratory X-ray diffractometer equipped with an in-plane arm to determine residual stress gradients is presented. The approach is based on an in-plane arm rotation and a characterization of several reflections to achieve a variation of X-ray penetration depth even without a sample inclination.
Synopsis: The crystalline structure and the melting/crystallization behavior of several synthesized diblock copolymers based on poly(-caprolactone) (PCL) and poly(L-lactic acid) (PLLA) have been studied by differential calorimetry and X-ray diffraction analysis (small-angle X-ray scattering and wide-angle X-ray diffraction). The influence of the presence and of the molecular weight of each block on the crystallinity behavior and the crystal nature of the other block is discussed.
Synopsis: A new model for the form factor of star polymers with excluded volume effect is presented.
Synopsis: This corrigendum replaces the first corrigendum [Popa & Balzar (2012). 45, 838-839], which was published to correct errors in the article by Popa & Balzar [J. Appl. Cryst. (2001), 34, 187-195].
Synopsis: The computer program, DPC toolkit, is a simple and user-friendly tool that identifies the unit-cell lattice parameters of a crystal structure which are consistent with a given set of two-dimensional grazing-incidence wide-angle X-ray scattering data.
Synopsis: A new six-axis robotic sample changer for neutron powder diffraction experiments including texture measurements enabling a new set of experiments to be performed at the high-pressure preferred orientation diffractometer at the Lujan Neutron Scattering Center.
Synopsis: The new release of the multi-functional computer program package WinXPRO v.3x for determination of the electron-density-based crystal properties from parameters of the multipole model is described.
Synopsis: In this paper, full-field lens-based microdiffraction imaging using X-rays is introduced as a fast technique for determining lattice strain and orientation on crystalline surfaces. With a total exposure time of less than a minute, lattice tilts down to 10-4° could be distinguished locally on a focused-ion-beam-milled silicon wafer over a surface area of 100 × 100 µm.
Synopsis: The nominal pitch of 25 nm of a self-assembled block copolymer line grating was determined as 24.83 (9) nm by the first traceable grazing-incidence small-angle X-ray scattering measurements. Traceability is established by tracing all input parameters; the main contributions are the measurements of the sample-detector distance and of the pixel size.
Synopsis: Epitaxial layers of topological insulators of Bi2Te grown by molecular-beam epitaxy are investigated by high-resolution X-ray diffraction.
Synopsis: This article reports the integral transform that determines the particle size distribution from the small-angle scattering intensity under the assumption that the particle correlation function is a polynomial.
