Single-crystal NaY(MoO(4))(2) thin plates dominated by high-energy {001} facets were hydrothermally synthesized under relatively mild conditions, free of organic additives, seeds and templates. The as-obtained NaY(MoO(4))(2) thin plates showed an excellent visible-light-responding photocatalytic activity for degradation of dyes in water.

The geometric percolation thresholds for circular, elliptical, square, and triangular plates in the three-dimensional space are determined precisely by Monte Carlo simulations. These geometries represent oblate particles in the limit of zero thickness. The normalized percolation points, which are estimated by extrapolating the data to zero radius, are etac=0.961 4+/-0.000 5, 0.864 7+/-0.000 6, ...

In order to introduce magnetic conductive thin plates in quasi-static PEEC method, a coupling with the integrodifferential method is proposed. This coupling enables to take the advantage of each method. The complex conductor geometry is achieved thanks to the PEEC method. The modeling of thin plates is taken into account thanks to an integro-differential one.

The aerodynamic noise of a thin rigid annulus (referred to as the ring here) placed in the mixing layer of a subsonic circular jet is investigated in the paper, both theoretically and experimentally. From the experimental point of view, the jet–ring configuration is understood as an axisymmetric alternative to more usual ones involving a rectangular aerofoil held between parallel side plates, d...

Acoustic properties of the metamaterial graded absorber, also known as ``acoustic black hole'', are studied in linear regime. The absorber consists thin metallic circular plates, each with a central perforation, separated by annular air cavities. Radius perforation plate is gradually decreasing distance from to front surface, forming channel staircase radius profile. A semi-analytical equivalen...
