The asymmetric unit of the title compound, C(17)H(14)N(2)O(4), contains two independent mol-ecules in which the benzene rings are in a trans arrangement with respect to the C=C double bond and the rings are inclined by 4.3 (1) and 22.1 (1)° with respect to each other.

The asymmetric unit of the title compound, C(30)H(24)N(2)O(2), contains two independent mol-ecules, which both lie on centers of inversion. The central phenyl-ene ring is inclined at 61.4 (2)° with respect to the flanking aromatic ring [dihedral angle = 70.7 (3)° in the second mol-ecule].

The title compound, C(15)H(14)O(5), crystallizes with two independent mol-ecules in the asymmetric unit in which the benzene rings are inclined at dihedral angles of 79.4 (1) and 84.2 (1)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into double chains propagating in [001].

The asymmetric unit of the title compound, C20H24N2, contains one half-mol-ecule, with the single C-C bond of the 1,4-di-aza-butadiene fragment situated on a centre of symmetry. The benzene rings are inclined to the 1,4-di-aza-butadiene mean plane by 59.5 (1)°.

Dispersion of super-paramagnetic nanoparticles in nonmagnetic carrier fluids, known as ferrofluids, offers the advantages of tunable thermo-physical properties and eliminate the need for moving parts to induce flow. This study investigates ferrofluid flow characteristics in an inclined channel under inclined magnetic field and constant pressure gradient. The ferrofluid considered in this work i...

The asymmetric unit of the title compound, C(20)H(24)N(2), contains one half -mol-ecule which exhibits a crystallographically imposed center of symmetry. The benzene rings are inclined to the 1,4-diaza-butadiene mean plane by 78.3 (2)°.

SUMMARY Acoustic field analysis results of surface acoustic wave dispersive delay lines using inclined chirp IDTs on a Y-Z LiNbO 3 sub-strate are described. The calculated results are compared with optical measurements. The angular spectrum of the plane wave method is applied to calculation of the acoustic fields considering the anisotropy of the SAW velocity by using the polynomial approximati...

Asymmetrically cut perfect crystals, in both the Laue and Bragg geometries, are examined as single crystal monochromators for x-ray beams that are collimated to a small fraction of the Darwin width, as is typical in experiments with coherent x rays. Both the Laue and asymmetric Bragg geometries are plagued by an inherent chromatic aberration that increases the beam divergence much beyond that o...
