The crystal structure and the magnetic ordering pattern of the electrically insulating perovskite CeVO3 was investigated by high-resolution powder X-ray diffraction and single-crystal neutron diffraction. A structural phase transition from an orthorhombic ...
We present three different prepn. methods for CdSe colloidal nanoparticles that, when carried out into the Ostwald ripening regime, lead to the development of complex spectral patterns resulting from the overlap of several distinct components corresponding ...
The thermal decomposition of alane was investigated by application of synchrotron X-ray diffraction (SR-XRD) and thermal desorption spectroscopy (TDS). Two polymorphs were studied, α- and γ-AlH3. Activation energies, anisotropic volume expansions, and phas ...
The incommensurately modulated scheelite-like KSm(MoO4)2 structure has been refined in the monoclinic superspace group I2/b(ab0)00 by the Rietveld method on the basis of synchrotron radiation powder diffraction data. The systematic broadening of satellite ...
Metergoline is a dopamine agonist and serotonin antagonist used both in human and veterinary medicine. In addition to the previously known crystalline form, a new polymorph, which crystallizes from aqueous solution, was found. Since it was initially imposs ...
X-ray induced anisotropic variations of cell parameters in porcine pancreatic elastase (PPE) were used in a multi-Pawley refinement in order to improve the deconvolution of overlapping peaks occurring in the high-angle region of the powder pattern. The ben ...
6,6-dimethylbicyclo[3.1.1]heptan-2-one, (1R)-(+)-nopinone, is a liquid at room temperature. It solidifies below 260 K to form an orientationally disordered body-centred cubic phase (a = 7.644 Å at 255 K), which transforms to an ordered structure below 240 ...
Some nonenzymic epoxide-initiated polyolefin cyclisations are reported. The presented molecules are partially constrained analogues of (3S)-oxidosqualene, the natural substrate to many important cyclase enzymes. These model compounds feature a preformed C- ...
A new target in AIDS therapy development is HIV-1 integrase (IN). It was proven that HIV-1 IN required divalent metal cations to achieve phosphodiester bond cleavage of DNA. Accordingly, all newly investigated potent IN inhibitors contain chemical fragment ...
The hydrothermal synthesis and structural characterization of the lanthanide silicate system [Na6Ln2Si12O30x H2O] (Ln=La3+, Sm3+, Eu3+, Gd3+, and Tb3+), named AV-21, has been reported. Structural elucidation of the Sm3+ analogue (isomorphous with the Eu3+, ...
