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

Electron crystallography [PDF]
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 ...

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

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

Spikes in Cosmic Crystallography
If the universe is multiply connected and small the sky shows multiple images of cosmic objects, correlated by the covering group of the 3-manifold used to model it.

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