AtomicControl : a crystallography simulator
… package designed to aid in the teaching of crystallography and x-ray diffraction concepts to materials science students. It has the capability to create an arbitrary crystal structure based on the user's specification of a space group and atomic coordinates. It also can generate a simulated …

Quantum Crystallography of Hydronium Cations
<p>Cationic hydronium clusters of the form [HaOb]^c,(c>0), have been investigated. After investigating over 2000 crystal structures containing hydronium cations found in the Cambridge Structural Database. The hydronium cationic compounds that were most unusual, mischaracterized, or those of …

Maximum Entropy Method in Superspace Crystallography
This thesis discusses several aspects of the combination of the Maximum Entropy Method (MEM) for the reconstructions of the electron density with the superspace approach to the description of structures of aperiodic crystals. It is shown that the MEM in superspace provides a parameter-free …

Protein Mechanics Through X-Ray Crystallography
… that cycles of mutagenesis coupled with X-ray crystallography can reveal an anisotropic, distributed pattern of physical interactions in a PDZ domain, PSD-95 PDZ3. This pattern is functionally important and deeply connected to the evolution of PDZ domains in general. Second, we present a new …

X-ray Crystallography of Inositol Dehydrogenase Enzymes
Lactobacillus casei BL23 expresses two enzymes encoded by the genes iolG1 and iolG2. They have been putatively assigned as myo-inositol dehydrogenases by sequence comparison. The enzyme catalyzes the reversible conversion of myo-inositol to scyllo-inosose and the concurrent reduction of NAD+ to …

Strain in Halide Perovskites: Characterisation, Crystallography, Consequences
Optoelectronic devices such as solar cells, LEDs, and X-ray detectors making use of halide perovskites as the light absorbing or emitting material have experienced a dramatic increase in efficiency in recent years. As a result, halide perovskite-based solar cells are now starting to make their way …

The crystallography of three flavor quark matter
The nature of cold three-flavor quark matter at the large (but not asymptotic) densities relevant to neutron star phenomenology is not resolved. The gapless CFL phase, which was previously believed to have the lowest free energy, was recently shown to be unstable in the sense that some phase must …

Fabrication, Kinetics and Crystallography of Lithium Disilicate Glass-Ceramics
… namely, fabrication, kinetics, and crystallography. One of the objectives is to fabricate a high-strength glass-ceramic in complex lithium disilicate glass systems for dental restorative applications by means of compositional design of parent glass and heat treatment optimization. …

Synthesis, crystallography and biological activity of myo-inositol phosphates
The antioxidant property of myo-inositol hexakisphosphate is important in the prevention of hydroxyl radical formation which may allow it to act as a 'safe' carrier of iron within the cell. Here, the hypothesis that the recently discovered natural product, myo-inositol 1,2,3-trisphosphate …

Solid-State Chemistry of Benzophenone Anils (x-Ray, Crystallography)
The crystal structures of some benzophenone anils were determined by X-ray diffraction. In five of the six structures the molecules adopted the trans configuration. The strong preference for this isomer in the solid state is in sharp contrast to the behavior in solution where previous workers found …

X-ray crystallography for the study of nickel and iron salicylaldimines
<p>"X-ray diffraction of single crystals has developed dramatically over the last century by combining fundamental theories of light, diffraction, and statistics to generate the complete, geometric structure of molecules. The quality of the resulting X -ray structure data are reported in R₁ < 5%, …
