X-Ray Crystallography of Viruses

, 2013
Since the 1970s and for about 40 years, X-ray crystallography has been by far the most powerful approach for determining virus structures at close to atomic resolutions. Information provided by these studies has deeply and extensively enriched and shaped our vision of the virus world.

The dependence of X-ray elastic constants with respect to the penetration depth [PDF]

, 2023
X-ray diffraction techniques are widely used to estimate stresses within polycrystalline materials. The application of these techniques requires the knowledge of the X-ray elastic constants relating the lattice strains to the stress state.

Characterization of Aptamer-Protein Complexes by X-ray Crystallography and Alternative Approaches [PDF]

, 2012
Aptamers are oligonucleotide ligands, either RNA or ssDNA, selected for high-affinity binding to molecular targets, such as small organic molecules, proteins or whole microorganisms.

Structural investigations of the regio- and enantioselectivity of lipases [PDF]

, 1998
Although lipases are widely applied for the stereospecific resolution of racemic mixtures of esters, the atomic details of the factors that are responsible for their stereospecificity are largely obscure. We determined the X-ray structures of Pseudomonas

(E)-1,3-Bis(anthracen-9-yl)prop-2-en-1-one: crystal structure and DFT study

Acta Crystallographica Section E: Crystallographic Communications, 2018
The title compound, C31H20O, was synthesized using a Claisen–Schmidt condensation. The enone group adopts an s-trans conformation and the anthracene ring systems are twisted at angles of 85.21 (19) and 83.98 (19)° from the enone plane.

Molecular structure, DFT studies and Hirshfeld analysis of anthracenyl chalcone derivatives

Acta Crystallographica Section E: Crystallographic Communications, 2018
The molecular and crystal structure of two new chalcone derivatives, (E)-1-(anthracen-9-yl)-3-[4-(piperidin-1-yl)phenyl]prop-2-en-1-one, C28H25NO, (I), and (E)-1-(anthracen-9-yl)-3-[4-(diphenylamino)phenyl]prop-2-en-1-one, C35H25NO, (II), with the fused ...

Ag on Ge(111): 2D X-ray structure analysis of the (Wurzel)3 x (Wurzel)3 superstructure [PDF]

, 1992
We have studied the Ag/Ge(111)(Wurzel)3 x (Wurzel)3 superstructure by grazing-incidence X-ray diffraction. In our structural analysis we find striking similarities to the geometry of Au on Si(111). The Ag atoms form trimer clusters with an Ag-Ag distance

Crystal structure and theoretical studies of two π-conjugated fused-ring chalcones: (E)-1-(anthracen-9-yl)-3-(9-ethyl-9H-carbazol-3-yl)prop-2-en-1-one and (E)-1-(anthracen-9-yl)-3-[4-(9H-carbazol-9-yl)phenyl]prop-2-en-1-one

Acta Crystallographica Section E: Crystallographic Communications, 2018
The title chalcones, C31H23NO and C35H23NO, were synthesized via Claisen–Schmidt condensation reactions. Both structures were solved and refined using single-crystal X-ray diffraction data and optimized at the ground state using the density functional ...
