MPI tray—a versatile crystallization plate for membrane proteins

A new crystallization plate (the MPI tray) was developed for UV and visible imaging with membrane protein samples. Optimization of the surface properties fundamentally enhanced the usability of the plate also in the presence of detergents. Here we report the design of a new crystallization plate, termed the MPI tray, which is optimized for UV and visible imaging with membrane protein samples. Following basic considerations regarding geometry and material, the surface properties of the plate were subjected to extensive analysis and modification in order to improve the performance in a robotic environment. An electrostatic surface potential was identified as the major problem affecting automated setup of experiments, and we found that treatment of the crystallization plate with ethanol is effective in removing this potential.

Roughness replication in neutron supermirrors

Long range interface roughness correlation in Ni-Ti neutron supermirrors is found to manifest in plateaus and peaks in the diffuse neutron scatter. The features are of resonant character and are strongly dependent on the type of the supermirror structure (slowly increasing or decreasing bilayer thickness). DWBA calculations yield the statistical parameters of the interface roughness correlations.

How many waters are detected in X-ray protein crystal structures?

The variability in the number of water molecules localized in protein crystallography depends not only on the crystallographic resolution, but also on other parameters. A multiple Poisson regression allows its estimation.

Neutron total scattering of crystalline materials in the gigapascal regime

The combination of high-pressure neutron diffraction and total scattering of crystalline materials presents several unique challenges to established data collection and analysis methods. This paper presents a simple reproducible method for the acquisition of high-quality neutron total scattering data from crystalline materials at high pressure.

Reliability of Multigrain Indexing for Orthorhombic Polycrystals above 1 Mbar: Application to MgSiO3-post-perovskite

Experiments and simulations are used to evaluate the applicability of multigrain crystallography for high pressure diamond anvil cell experiments. The method allows retrieving a large portion of the illuminated sample grains with an average theoretical resolution in grain orientation of 0.02° and a spatial resolution that requires further improvements.

Phase equilibria in the ternary reciprocal system Li, Ba // BO2, F and growth of bulk β-BaB2O4 crystals

On the basis of studies using a combination of differential thermal analysis, visual polythermal analysis and solid state synthesis, a detailed investigation into phase formation in the ternary reciprocal system Li, Ba // BO2, F has been carried out and its importance in growing barium borate crystals has been shown. The liquidus of the system is composed of primary crystallization fields of six compounds – BaB2O4, BaF2, LiBaF3, LiF, LiBO2 and LiBa2B5O10 – separated by co-crystallization curves and four nonvariant points.

Approximating the near-edge mass absorption coefficients for Ni using an ultra-thin bimetal foil

Absorption measurements made using an ultra-thin (0.98/0.67 µm) Ti–Ni foil were used to fit Ni mass absorption coefficients just beyond the Ni K edge, with uncertainties of ±1%. A comprehensive list of mass absorption coefficients was compiled in the near-edge region, providing a significant improvement over existing coefficients present in the NIST XCOM and FFAST databases.

Qu­antitative X-ray pair distribution function analysis of nanocrystalline calcium silicate hydrates: a contribution to the understanding of cement chemistry

Quantitative analysis of the X-ray pair distribution function collected on calcium silicate hydrates having Ca/Si ratios ranging between 0.57 and 1.47 was applied. With increasing Ca/Si ratio, Si bridging tetrahedra are omitted and Ca(OH)2 is detected at the highest ratios.
