The analytic expression of the time evolution of the Reynolds stress anisotropy tensor in all planar homogeneous ows is obtained by exact integration of the modeled di erential Reynolds stress equations. The procedure is based on results of tensor representation theory, is applicable for general pressure-strain correlation tensors, and can account for any additional turbulence anisotropy e ects...

Liquid phase syntheses mainly yield nanoparticles with compact shapes, such as spheres or cubes. However, controlling not only the size but also shape of magnetic would enable a fine-tuning their intrinsic properties, due to anisotropy induced by long-range dipolar interactions. We report here fairly simple approach based on reduction an amidinate complex in presence mixture long-chains acid an...

Proteins, molecules, and macromolecular assemblies in water are surrounded by a nanometer-sized hydration layer with properties very different from bulk water. Here, we use classical molecular dynamics simulations to study the dielectric response of hydration water next to hydrophobic and hydrophilic planar surfaces. We find the interfacial dielectric absorption of water to be strongly anisotro...

Trie randomly pinned planar flux bne array is supposed to show a phase transition to a vortex glass phase at low temperatures. This transition bas been examined by using a mapping onto a 2D XY-mortel with random anisotropy but without vortices and applying a
