▪ Abstract Granular materials segregate. Small differences in either size or density lead to
flow-induced segregation, a complex phenomenon without parallel in fluids. Modeling of …

Granular hydrogels are composed of hydrogel-based microparticles, so-called microgels,
that are densely packed to form an ink that can be 3D printed, injected or cast into …

We report the observation of coexisting Bose-Einstein condensate (BEC) and Fermi gas in a
magnetic trap. With a very small fraction of thermal atoms, the 7 Li condensate is quasipure …

Most studies on granular physics have focused on dry granular media, with no liquids
between the grains. However, in geology and many real world applications (eg food …

Recent advances in understanding model systems of wet granular materials are presented,
with particular emphasis on statistical concepts, dynamics, and phase transitions. It is …

In 1773 Coulomb recognized that the static properties of granular systems can be discussed
in terms of the frictional properties between different layers, leading to his relationship …

When a granular material such as sand is mixed with a certain amount of liquid, the surface
tension of the latter bestows considerable stiffness to the material, which enables, for …

The objective of this paper is to identify a numerical method to simulate motion of a packed
or fluidized bed of fuel particles in combustion chambers, such as a grate furnace and a …

We have studied the drag force acting on an object moving with low velocity through a
granular medium. Although the drag force is a dynamic quantity, its behavior in this regime is …

Heat transfer in particulate systems is important to a vast array of industries, yet is poorly
understood even in the simplest case—conduction through the solid phase. This is due in …
