A new NCPSS BL19U2 beamline at the SSRF for small-angle X-ray scattering from biological macromolecules in solution

A new biological small-angle X-ray scattering beamline (BioSAXS, BL19U2) is dedicated exclusively to small-angle scattering experiments from biological macromolecules in solution. As part of the important facilities in the National Center for Protein Sciences Shanghai (NCPSS), this BioSAXS beamline is the first in China to serve the rapidly increasing biology communities.

Phase-targeted X-ray diffraction

A method to enhance the X-ray diffraction signal of a specific, targeted crystalline phase within a sample is presented. This technique can be implemented in a handheld or in-line instrument format.

Qu­antitative Characterization of the Microstructure of Heat-Treated Zr-Excel by Neutron Line Profile Analysis

Heat treatments in the (α+β) or β-phase regime and subsequent cooling induce significant microstructural changes in the Zr-Excel (Zr-3.5Sn-0.8Mo-0.8Nb) by generating non diffusional complex martensitic products. In the current study we show how modern whole pattern diffraction Line Profile Analysis (LPA) can individually characterize the defect structure of the martensitic and non-martensitic components of heat-treated Zr-Excel samples.In the current study we show how modern whole pattern diffraction Line Profile Analysis can individually characterize the defect structure of the martensitic and non-martensitic components of heat-treated microstructures.

Asymmetric Band-flipping for Time-of-flight Neutron Diffraction Data

The band-flipping algorithm for structure solution with neutron data has been modified to account for the possible differing size of positive and negative neutron scattering lengths in a sample. Together with the band-modification of low-density elimination it has been implemented in TOPAS and tested with both powder and Laue single crystal time-of-flight neutron diffraction data.

Simultaneous small-angle neutron scattering and Fourier transform infrared spectroscopic measurements on cocrystals of syndiotactic polystyrene with polyethylene glycol di­methyl ethers

A new simultaneous measurement method combining small-angle neutron scattering and Fourier-transform infrared spectroscopy was applied to a study on a syndiotactic polystyrene cocrystal with polyethylene glycol dimethyl ether with a molecular weight of 500. It is suggested that the guest molecules in the crystalline region have an elongated structure along the thickness direction of the crystalline lamellae.

Gas-sensitive biological crystals processed in pressurized oxygen and krypton atmospheres: deciphering gas channels in proteins using a novel `soak-and-freeze' methodology

A novel cryogenic gas pressure cell has been designed for structural studies of enzymes requiring gaseous-substrates. The proof of principle is demonstrated for test crystals. The pressure cell has been designed study of O2-sensitive proteins to reveal pores, channels and reactive-centers, and thus to decipher O2 traffic in proteins.

Guinier peak analysis for visual and automated inspection of small-angle X-ray scattering data

Guinier peak analysis (GPA), derived from the Guinier approximation, transforms the Guinier region of small-angle X-ray scattering data into a characteristic peak that verifies the existence of the Guinier region in the data. Deviation of the Guinier peak position in dimensionless GPA plots can be a useful addition to sample characterization and parameter validation protocols.

A new method for qu­antitative phase analysis using X-ray powder diffraction: direct derivation of weight fractions from observed integrated intensities and chemical compositions of individual phases

A new method for the quantitative phase analysis of multi-component polycrystalline materials using the X-ray powder diffraction technique is proposed. The method can derive weight fractions from single-measurement integrated intensity datasets for individual phases and their chemical compositions. No standard reference material, reference intensity ratio or crystal structural parameter is required.

The lattice tilts and full strain tensor are measured in Ge micro-devices under uniaxial or biaxial stress using standard and rainbow-filtered Laue micro-diffraction. Maps with sub-micrometre resolution of the strain tensor components are in very good agreement with finite element simulations.
