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

open access: yesIUCrJ, 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.

An insight into the microstructures and composition of 2,700 m-depth deep-sea limpet shells

open access: yesFrontiers in Marine Science, 2022
Structural and physiochemical properties contribute to the biological adaptation of deep-sea animals to their harsh living environment but have hardly been investigated systematically.

Crystallography with powders

open access: yesNature Materials, 2014
Over the course of its long history, powder diffraction has provided countless insights into the properties of materials. It will continue to do so in the future, but with an emphasis on elucidating how materials respond to external stimuli.

Electron crystallography [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 1996
The idea of solving unknown crystal structures from experimental electron-diffraction intensities and high-resolution electron micrographs has remained a controversial topic in the 60 year history of electron crystallography. In this review it will be shown that the application of modern direct phasing techniques, familiar to X-ray crystallographers ...

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

open access: yesFrontiers 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

open access: yesCrystals, 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.

Amplification of UV radiation and gain mechanisms in ZnO films with loose-packed structure

open access: yesКомпьютерная оптика
The modern demands for miniaturization of optoelectronic devices, in particular, for the UV range, are inextricably linked with the improvement of fabrication technologies for the corresponding photonic nano/micro objects and the study of their radiative

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

open access: yesNanomaterials, 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.
