Fifteen years of the Protein Crystallography Station: the coming of age of macromolecular neutron crystallography

IUCrJ, 2017
The Protein Crystallography Station (PCS), located at the Los Alamos Neutron Scattering Center (LANSCE), was the first macromolecular crystallography beamline to be built at a spallation neutron source.

Structure and mutation of deoxypodophyllotoxin synthase (DPS) from Podophyllum hexandrum

Frontiers in Catalysis, 2023
Deoxypodophyllotoxin synthase (DPS) is a 2-oxoglutarate (2-OG) dependent non-heme iron (II) dioxygenase that catalyzes the stereoselective ring-closing carbon-carbon bond formation of deoxypodophyllotoxin from the aryllignan (−)-yatein ...

Gender and Library of Mineralogy

Crystals, 2022
Few would expect women to feature often in the literature on minerology from the 15th through the 19th centuries, the recorded history of science being what it is.

Microstructural Study of MgB₂ in the LiBH₄-MgH₂ Composite by Using TEM

Nanomaterials, 2022
The hampered kinetics of reactive hydride composites (RHCs) in hydrogen storage and release, which limits their use for extensive applications in hydrogen storage S1and energy conversion, can be improved using additives.

Copernican Crystallography

, 1991
Redundancies are pointed out in the widely used extension of the crystallographic concept of Bravais class to quasiperiodic materials. Such pitfalls can be avoided by abandoning the obsolete paradigm that bases ordinary crystallography on microscopic ...

X-ray-Induced Heating in the Vicinity of the X-ray Interaction Point

Applied Sciences, 2023
When X-rays pass through a material, radiation damage occurs, and heat is generated at the X-ray interaction point, which can then be transferred around the X-ray irradiation site. This X-ray-induced heat transfer can affect the temperature of the sample

An N4-Tetradentate Hydrazone Ligand That Binds in a Neutral, Mono- and Bisdeprotonated Form to Iron(II) and Zinc(II) Metal Ions

Crystals, 2021
The coordination chemistry of butane-2,3-dione bis (2′-pyridylhydrazone) towards the divalent first-row transition metals zinc and iron has been explored. Depending upon the conditions, the ligand in the six complexes was found to be either neutral, mono,

Crystallography on Curved Surfaces

, 2006
We study static and dynamical properties that distinguish two dimensional crystals constrained to lie on a curved substrate from their flat space counterparts.
