Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a ...

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...

And to address indoor air quality effectively, you have to remove all types of contaminants, which include particulate matter (a mixture of solid particles and liquid droplets) and gases.

The four fundamental states of matter are solid, liquid, gas and plasma, but there others, such as Bose-Einstein condensates and time crystals, that are man-made.

Blue Air is out with connected air purifiers that give you more control over the air quality in your home, which is needed now more than ever.

Plastic particles are found in our organs, blood and even semen. But do they stay in us forever? What damage are they doing? Here are six questions scientists are trying to answer.

Explain that the little balls represent the particles of a solid, in this case the atoms in a metal. Although atoms and molecules are different, this same simple model of balls is used for both. Let ...

For the first time, ETH Zurich Materials Scientists are measuring the rolling friction of tiny, micrometre-sized particles. These measurements permit them to better understand everyday products such ...

Materials scientists recorded solid platinum atoms "swimming" in a liquid graphene cell, two materials with wide technological applications.

Wildfires pollute the air with smoke, dust, ash. Here's how to protect yourself Wildfire smoke contains small particles that can cause serious health problems.

The liquid particles are small enough to pass through the filter paper as a filtrate. The solid particles are too large to pass through the filter paper and stay behind as a residue.
