Serial electron crystallography: merging diffraction data through rank aggregation [PDF]

open access: yes, 2017
Serial electron crystallography is being developed as an alternative way to collect diffraction data on beam-sensitive polycrystalline materials. Merging serial diffraction data from a large number of snapshots is difficult, and the dynamical nature of ...

Multigrain crystallography

open access: yesZeitschrift für Kristallographie, 2012
We summarize exploratory work on multigrain crystallography. The experimental arrangement comprises a monochromatic beam, a fully illuminated sample with up to several hundred grains in transmission geometry on a rotary table and a 2D detector. Novel algorithms are presented for indexing, integration and filtering with emphasis on handling the ...

The advanced treatment of hydrogen bonding in quantum crystallography [PDF]

open access: yes, 2021
Although hydrogen bonding is one of the most important motifs in chemistry and biology, H-Atom parameters are especially problematic to refine against X-ray diffraction data. New developments in quantum crystallography offer a remedy.

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 ...

Structure determination of membrane proteins by electron crystallography [PDF]

open access: yes, 2007
A fundamental principle of life is the separation of environments into different compartments. Prokaryotes shield their interior from the environment by a plasma membrane and in some cases also by a cell wall.

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
