Tiny self-powered Janus particles navigate tight spaces, showing promise for health and environmental problem-solving.

Calcium carbonate is everywhere. From seashells to eggshells to antacid medicine, it is one of the most abundant minerals on our planet. But scientists still don’t agree on how it forms its many ...

It is then shaped and compressed so the calcium carbonate particles bond and solidify. Heat is applied in the final stage to complete the process. The scientists discovered that the concrete ...

The result is microsphere crystals of calcium carbonate, but that was only half ... and the current recipe is an acrylic with suspended water particles. Mix water, acetone, and bits of Plexiglas.

The calcium carbonate precipitated out of the water and eventually ... The stalk keeps the animal attached to the sea floor and the petal-like tentacles extend out and filter food particles from the ...

In the first experiment, they change the size of the calcium carbonate particles, using large lumps, small lumps and powder. In the second experiment, they change the concentration of the acid.

increasing the release of harmful particles into marine environments. "Our findings suggest that PET glitter can serve as artificial templates for calcium carbonate formation, which may have ...
