The acridine ring system and the benzene ring in the title compound, C(20)H(13)NO(2), are oriented at a dihedral angle of 6.4 (2)°. The carboxyl group is twisted at an angle of 83.6 (2)° relative to the acridine skeleton. The mol-ecules in the crystal are arranged in stacks along the b axis, with two of the acridine rings involved in multiple π-π inter-actions [centroid-centroid distances in th...
Expanding electronegative EN plasmas have been previously observed, experimentally, to generate wave activity. Using a particle-in-cell PIC code we have investigated these waves in expanding EN plasmas containing a double layer DL between an upstream source region and an expanded downstream region. Oxygen reaction rates were used but modified to correspond more closely to experimental condition...
The electrophoretic mobilities of two interacting spheres are calculated numerically for arbitrary values of the double-layer thickness. A general formula for the electrophoretic translational and angular velocities of N interacting particles is derived for low-zeta-potential conditions. The present calculation complements the well-studied case of thin double layers. The results are compared wi...
Single crystals of the title compounds were prepared by solid-solid reaction using BaCl2 or BaBr2 flux at 1100°C. The structures of these two new cobaltites were solved and refined in the trigonal symmetry with space group R3 m: a=5.716(2) Å, c=45.01(3) Å for Ba2Co4ClO7 and a=5.7434(5) Å, c=46.151(9) Å for Ba2Co4BrO7. The two compounds are isostructural and their structures can be considered as...
We present measurements of transmission of infrared radiation through double-layer metallic grating structures. Each metal layer contains an array of subwavelength slits and supports transmission resonance in the absence of the other layer. The two metal layers are fabricated in close proximity to allow coupling of the evanescent field on individual layers. The transmission of the double layer ...
