A new form of NaMnAsO4

Acta Crystallographica Section E: Crystallographic Communications, 2019
A new form of NaMnAsO4, sodium manganese(II) orthoarsenate, has been obtained under hydrothermal conditions, and is referred to as the β-polymorph. In contrast to the previously reported orthorhombic α-polymorph that crystallizes in the olivine-type of ...

Comparison of silver and molybdenum microfocus X-ray sources for single-crystal structure determination

Journal of Applied Crystallography, 2015
A detailed comparison of single-crystal diffraction data collected with Ag Kα and Mo Kα microsources (IµS) indicates that the Ag Kα data are better when absorption is significant. Empirical corrections intended to correct for absorption also correct well

Structural Analysis of Xylose Isomerase from Streptomyces avermitilis

Crystals
Xylose isomerase (XI, also known as glucose isomerase) is an oxidoreductase that interconverts aldoses and ketoses. XI catalyzes the reversible isomerization of D-glucose and D-xylose into D-fructose and D-xylulose, respectively.
