X-ray crystallography of krinovite [PDF]
The unit cell of the meteoritic mineral krinovite, NaMg2CrSia01o, is triclinic with a = 10.22, b = 10.67, c = 8.80 A, IX = 10508', {l =. 960 36', y = 12501'. The monoclinic unit cell given by OLSEN and FUCHS is one of the possible pseudomonoclinic cells.

Development of EM-CCD-based X-ray detector for synchrotron applications [PDF]
A high speed, low noise camera system for crystallography and X-ray imaging applications is developed and successfully demonstrated. By coupling an electron-multiplying (EM)-CCD to a 3:1 fibre-optic taper and a CsI(Tl) scintillator, it was possible to ...

Serial Electron Diffraction Data Processing With diffractem and CrystFEL [PDF]
Serial electron diffraction (SerialED) is an emerging technique, which applies the snapshot data-collection mode of serial X-ray crystallography to three-dimensional electron diffraction (3D Electron Diffraction), forgoing the conventional rotation ...

SLC7A11 frequently migrates faster in SDS‐PAGE. The present study found that the high hydrophobicity of SLC7A11 causes its anomalous migration in SDS‐PAGE with a low concentration of acrylamide gel. Replacing isoleucine with asparagine reduced hydrophobicity and restored its normal migration at 55 kDa, revealing the role of hydrophobicity and gel ...

N-{(Z)-3-Oxo-3-[(E)-(pyridin-2-ylmethyl)diazenyl]-1-(thiophen-2-yl)prop-1-en-2-yl}benzamide
In the title compound, C20H16N4O2S, the thiophene ring subtends dihedral angles of 58.6 (3) and 9.8 (3)° with the benzamide and pyridine rings, respectively, whereas these two rings are inclined to one another by 59.3 (3)°. There is an intramolecular C—H.

Protein structural biology came a long way since the determination of the first three-dimensional structure of myoglobin about six decades ago. Across this period, X-ray crystallography was the most important experimental method for gaining atomic ...

Self-Supervised Deep Learning for Model Correction in the Computational Crystallography Toolbox [PDF]
The Computational Crystallography Toolbox (CCTBX) is open-source software that allows for processing of crystallographic data, including from serial femtosecond crystallography (SFX), for macromolecular structure determination. We aim to use the modules in CCTBX to determine the oxidation state of individual metal atoms in a macromolecule.

Rapid sample delivery for megahertz serial crystallography at X-ray FELs
Sample delivery is a major challenge to performing serial crystallography experiments at upcoming high-repetition-rate X-ray free-electron lasers. The feasibility of using gas-driven liquid jets for this purpose at the FLASH facility in Hamburg has been ...
