To demonstrate a facile method to control capillary condensation via the design of confined geometric structures, we use a particle self-assembly technique to fabricate porous materials with well-defined pore sizes. Four groups of silica particles we

One significant hindrance to the development of granular segregation rate models is the inherent difficulty of performing the dynamic experiments required for validation. Here, we seek to overcome this experimental hurdle by establishing an “equili

The measurement of the rupture force for an axially strained liquid bridge has been the subject of research for the last three decades and is fundamental to the understanding of the behavior of multiphase systems in granular materials. The study here

The passive separation of a binary mixture of spherical particles is accomplished using a laboratory scale quasi two-dimensional inclined board such that gravity alone drives the flow of the mixture through a static array of obstacles. Experimental r

Metal-support interactions significantly affect the stability and activity of supported catalytic nanoparticles (NPs), yet there is no simple and reliable method for estimating NP-support interactions, especially for amorphous supports. We present an

An accurate description of metal nanoparticle (NP)–support interactions is required for designing and optimizing NP catalytic systems because NP–support interactions may significantly impact NP stability and properties, such as catalytic activity

Here, we show a direct connection between density-based segregation and granular rheology that can lead to insight into both problems. Our results exhibit a transition in the rate of segregation during simple shear that occurs at I∼0.5 and mimics a

Handling of granular materials involves the use of many solids processing devices such as chutes, hoppers, tumblers or other transfer equipment. Unfortunately, granular materials segregate if they are subjected to flow or external agitation in the pr

Segregation is a major problem for many solid processing industries. Differences in particle size or density lead to flow-induced segregation within the surface layer. Here we examine methods of avoiding radial segregation in a horizontal drum mixer.

Platelets play a critical role in the mechanics and dynamics of blood clots, but the exact contribution of individual platelets on the macro-scale mechanics of whole clots is not fully understood. To elucidate the trans-scale relationship, we have de
