The Advanced Photon Source (APS) at Argonne National Laboratory was used to obtain real-time, high-resolution x-ray diffraction measurements to determine the microscopic response of shock-compressed single crystals. Disk shaped samples were subjected to plane shock wave compression by impacting them with half-inch diameter, flat-faced projectiles. The projectiles were accelerated to velocities ...
Abstract Single crystals of Dy 11 Ge 4.33 In 5.67 were grown from a sample the starting composition 55 20 25 by arc-melting and subsequent annealing. crystallizes with Sm 4 6 -type structure, space group I 4/ mmm, which was refined single-crystal X-ray diffractometer data: = 11.4329(16), c 16.168(3) Å, w R 2 0.0341, 927 F values 42 parameters. The isotypic compound Tm characterized powder diffr...
We present the refinement of the crystal structure of charge-ordered LuFe2O4, based on single-crystal x-ray diffraction data. The arrangement of the different Fe-valence states, determined with bond-valence-sum analysis, corresponds to a stacking of charged Fe bilayers, in contrast with the polar bilayers previously suggested. This arrangement is supported by an analysis of x-ray magnetic circu...
Bulk single crystals of pure and xylenol orange dye (XO) admixtured L-Alanine Thiourea (LATU) were grown by slow evaporation technique. The cell parameters and crystallinity of pure and dye admixtured LATU crystals were confirmed by single crystal, powder X-ray diffraction and high resolution X-ray diffraction analyses. The functional groups present in the crystals were confirmed by FTIR analys...
An organic nonlinear optical (NLO) single crystal has been synthesized by slow solvent evaporation technique from aqueous solutions of L-serine and sodium fluoride (NaF) at ambient temperature. The grown crystal was confirmed by single crystal X-ray diffraction analysis. The powder X-ray diffraction of the grown crystal was recorded and indexed. The functional groups of the grown crystals were ...
A series of N-ethyl phthalimide esters 4(a-n) were synthesized and characterized by spectroscopic studies. Further, the molecular structure of majority of compounds were analysed by single crystal X-ray diffraction studies. The X-ray analysis revealed the importance of substituents on the crystal stability and molecular packing. All the synthesized compounds were tested for in vitro antioxidant...
The classification of the title compound, tridysprosium nickel, into the Fe3C (or Al3Ni) structure type has been deduced from powder X-ray diffraction data with lattice parameters reported in a previous study [Lemaire & Paccard (1967 ▶). Bull. Soc. Fr. Mineral. Cristallogr. 40, 311-315]. The current re-investigation of Dy3Ni based on single-crystal X-ray data revealed atomic positional paramete...
