Under the right conditions, sand can flow. When heavier grains are placed atop lighter grains in a container, the less dense grains can burble upward like the blobs of a lava lamp, a study finds. The ...

In its current form, the new diffuser could be used to calibrate a wide range of imaging systems, but the researchers believe that their mechanism could ultimately lead to holographic video screens or ...

Researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. The discovery of how to mix tiny liquid volumes arose from research directed at improving the ...

The choice of possible mixing and blending equipment for the preparation of solid and semisolid dosage formulations is extensive. Therefore, the first step in a successful mixing process is to select ...
