A graduate student accidentally created a blend of oil, water and nickel particles that formed an unexpected shape.

On a regular day in the laboratory, Raykh was mixing a batch of immiscible liquids and magnetized nickel particles. This is quite the equivalent of a scientific salad dressing, where the ...

Typically, particles added to an oil-and-water mixture decrease the tension at the interface between the two liquids, allowing them to mix. But in a twist, particles that are magnetized strongly ...

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