When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very ...

Understanding the way a wave moves through granular materials—after an earthquake, for example—has vast implications for modern science. After all, scientists use stress wave propagation through ...

Slip sliding away: illustration based on false-colour image of sheared grains and sound waves. (Courtesy: Ted Brzinski) A new experiment has revealed how sheared granular materials emit sound waves ...

Editor’s note: The following research is among the many talks that scientists from UChicago and its affiliated laboratories will present Feb. 13-17 at the annual meeting of the American Association ...

Granular materials and fine powders are used across various industrial processes and applications. To optimize and control processing methods, these materials have to be characterized precisely.

When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very ...

Granular materials contain large numbers of small, discrete particles, which collectively behave like uniform media. Their thermal conductivity is crucial to understanding their overall behaviour – ...

Did you eat cereal this morning? Or have you walked on a gravel path? Maybe you had a headache and had to take a pill? If you answered any of these questions with a yes, you interacted with a granular ...

Stress wave propagation through grainy, or granular, materials is important for detecting the magnitude of earthquakes, locating oil and gas reservoirs, designing acoustic insulation and designing ...
