When air quality is ranked "unhealthy for vulnerable groups" it means PM 2.5 are at levels that can cause problems for people ...

The particles here are greater than 5 x 10-7 m in size, which means that the person can see the particles with the naked eye. Fine sand mixed in water is a basic example of a suspension.

The particles in a colloid are spread throughout the mixture and are small enough to pass through a coffee filter. Where the particles in a suspension will eventually settle, the particles in a ...

Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, ...

The same team has now developed a general way to predict phase diagrams for complex mixtures containing two types of hard particles. They did this using an extension of their previous technique that ...

Fireworks are happening across the city again this year, which poses two issues–highly concentrated pollution, and uniquely ...

Air quality is uniquely terrible after all those official and illegal fireworks are detonated to celebrate Independence Day.

The research, published in Nature Physics, details a mixture of oil, water and magnetized particles that, when shaken, always quickly separates into what looks like the classically curvaceous ...
