Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

High resolution double crystal X-ray diffractometry and topography of III-V semiconductor compounds [PDF]

open access: yes, 1991
Double crystal diffractometry and topography are now routinely used in many laboratories for the inspection of epitaxially grown devices. However the trend towards thinner layers and more complex structures requires the continued development of novel ...

Crystal structure of AlFe0.95

open access: yesIUCrData, 2023
Three B2-type intermetallic AlFe1 – δ phases (0.18 < δ < 0.05) in the Al–Fe binary system were synthesized by smelting and high temperature sintering methods. The exact crystal structure for δ = 0.05 was refined by single-crystal X-ray diffraction.

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

open access: yesFEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Growth and characterization by x-ray topography of highly perfect crystals [PDF]

open access: yes, 1989
Single nickel crystals were grown from the melt by the Czochralski technique. Domain wall movements under applied magnetic fields were observed by using the Lang technique for X-ray topography. Magnetization measurements at room temperature were recorded

Nonlinear optical behaviour of bis (cytosinium) tartarate monohydrate single crystal

open access: yesChemical Physics Impact, 2022
A nonlinear optical single crystal of bis (cytosinium) tartarate monohydrate (BCTM) was grown by slow evaporation method at room temperature. Single crystal X-ray diffraction study revealed their cell parameters and corresponding space group.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

The polymorphs and solvates of phenylbutazone and their phase transition behaviour [PDF]

open access: yes, 2009
In this study, which was conducted between March 2007 and December 2008, the crystal structure of the alpha polymorph of phenylbutazone has been determined by single crystal X-ray diffractometry.

Crystal structure of apatite type Ca2.49Nd7.51(SiO4)6O1.75

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
The title compound, Ca2+xNd8–x(SiO4)6O2–0.5x (x = 0.49), was synthesized at 1873 K and rapidly quenched to room temperature. Its structure has been determined using single-crystal X-ray diffraction and compared with results reported using neutron and X ...
