Honey is already a pretty thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs ...

Capillary suspensions are defined by a small volume of an immiscible secondary fluid introduced to a particle–fluid suspension, triggering the formation of liquid bridges that interconnect particles ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...

Tangled chains lead to shear thickening Simulations showing the emergence of chains of particles in a suspension. The image on the left shows isolated chains in a suspension with a relatively low ...

The measuring tip of an atomic force microscope with a specially designed holder in which a spherical particle is “trapped”. Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are ...
