Information for phase identification may be gathered in the electron transmission microscope with spatial resolution down to the nanometre scale. Energy dispersive X-ray and electron energy loss spectrometries are based on inelastic electron/sample interac ...
SUPERFLIP is a computer program that can solve crystal structures from diffraction data using the recently developed charge-flipping algorithm. It can solve periodic structures, incommensurately modulated structures and quasicrystals from X-ray and neutron ...
The pyroelectric coefficients of 0.72Pb(Mg1/3Nb2/3)O-3-0.28PbTiO(3) (PMN-28PT), 0.67Pb(Mg1/3Nb2/3)O-3-0.33PbTiO(3) (PMN-33PT), and 0.92 Pb(Zn1/3Nb2/3)O-3-0.08PbTiO(3) (PZN-8PT) single crystals, oriented and poled along three different crystallographic dire ...
The reaction of [ReBr3(CO)(3)]NEt4 with 3-hydroxy-1,2,3-benzotriazine-4 (3 H) -one in the presence of base gave the ionic rhenium complex [ReBr(C7H4N3O2)(CO)(3)][NEt4] (2) which was crystallographically characterized. A neutral metallamacrocycle 3 was ...
We describe a highly effective method of reducing thermal sensitivity in piezoresistive sensors, in particular silicon cantilevers, by taking advantage of the dependence of the piezoresistive coefficient of silicon on crystallographic orientation. Two simi ...
LaCoO3 perovskite was prepared at 700degreesC using citrate precursors. The product was then characterized with X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS). The powder XRD pattern indicates rhomboliedral (R (3) over barc) or its monocli ...
The plastic response of a sheet metal is governed by the collective response of the underlying grains. Intragranular plasticity depends on intrinsic variables such as crystallographic orientation and on extrinsic variables such as grain interactions; howev ...
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 ...
Since the discovery of X-ray diffraction, it was believed that the discrete distribution of diffracted intensities was a direct consequence of the periodic arrangement of atoms in the three dimensions of space. However, in the last thirty years many exampl ...
The present study reports on the synthesis of nanocrystalline (K-x,Na1-x)NbO3 powders prepared via microemulsion mediated hydrolytic decomposition of mixed alkoxide solutions. Compositions with different K/Na ratios ranging between the two end members KNbO ...
