An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

Latex paints and drug suspensions such as insulin or amoxicillin that do not need to be shaken or stirred may be possible thanks to a new understanding of how particles separate in liquids, according ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior ...
