Micro-Macro Quantification of the Internal Structure of
The correlation between the anisotropic fabric tensor and the macro behavior of granular materials was verified with numerical simulations. The results showed that the new material anisotropic tensor is a more effective definition than the existing ones based on particle orientations and contact normals.

Influence of particle shape on sheared dense granular
Mar 13 2007 · We study by means of molecular dynamics simulations of periodic shear cells the influence of particle shape on the global mechanical behavior of dense granular media. At large shear deformation samples with elongated particles independent of their initial orientation reach the same stationary value for both shear force and void ratio. At the micro-mechanical level the stress the fabric

Liquid crystalWikipedia
Liquid crystals (LCs) are a state of matter which has properties between those of conventional liquids and those of solid crystals.For instance a liquid crystal may flow like a liquid but its molecules may be oriented in a crystal-like way. There are many different types of liquid-crystal phases which can be distinguished by their different optical properties (such as textures).

Anisotropies of Solar Cosmic RaysNASA/ADS
The behavior of the anisotropy during solar cosmic-ray events is discussed in terms of a simple model in which cosmic-ray particles propagate along the mean interplanetary magnetic field undergoing pitch-angle scattering. It is shown that a generalized form of the telegraph equation should be used when the anisotropy is large (i.e. greater than 30 ) but that the usual diffusion equation is

Janus particles are special types of nanoparticles or microparticles whose surfaces have two or more distinct physical properties. This unique surface of Janus particles allows two different types of chemistry to occur on the same particle.
