Granular Activated Carbon (GAC) Selection

Granular activated carbons are a very versatile group of adsorbents, with capability for selectively adsorbing thousands of organic and certain inorganic materials. From medicinal uses of powdered carbons in ancient Egypt, through charred interiors of whiskey barrels, carbon has been activated and used as an adsorbent for centuries. Granular vapor phase activated carbon media was first widely u...

Dynamics of Granular Systems

Granular media are dissipative systems. The collisions between the grains are inelastic and therefore energy is intrinsically lost within the system while it is in motion. In order to explore some of the fundamental resulting effects on the statistical properties of such systems, let us idealize a granular medium by a set of N spherical particles, all being identical and having only the exclusi...

Dynamics of Granular Stratification

Spontaneous stratification in granular mixtures—i.e., the formation of alternating layers of small-rounded and large-faceted grains when one pours a random mixture of the two types of grains into a quasi-twodimensional vertical Hele-Shaw cell—has been recently reported by H. A. Makse et al. @Nature 386, 379 ~1997!#. Here we study experimentally the dynamical processes leading to spontaneous str...

Dynamics of granular media

Granular media are very common in nature and technology but present, due to the inelasticity of the collisions between grains very astonishing collective phenomena. One of them is the spontaneous formation of clusters as observed in intergalactic dust. We will discuss the role of dissipation in these effects and show recent progress in the understanding of the deviation from classical thermodyn...

Heterogeneities in granular dynamics.

The absence of Brownian motion in granular media is a source of much complexity, including the prevalence of heterogeneity, whether static or dynamic, within a given system. Such strong heterogeneities can exist as a function of depth in a box of grains; this is the system we study here. First, we present results from three-dimensional, cooperative and stochastic Monte Carlo shaking simulations...
