Calcium carbonate, often referred to as lime or chalk, forms a hitherto unknown crystal structure as researchers working with P. Fratzl of the Max Planck Institute of Colloids and Interfaces have ...

Calcium carbonate (CaCO3) is a natural product found in many settings, including the minerals aragonite1 and calcite2; the sedimentary rocks limestone3 and chalk4; and animal structures such as ...

What links sea urchins, limestone and climate change? The common thread is calcium carbonate, one of the most widespread minerals on Earth. UC Davis researchers have now measured the energy changes ...

Calcium carbonate supplements are an effective way to increase your calcium intake if your diet isn’t sufficient, or you have a condition that leads to lower calcium levels. Learn about ...

The nano calcium carbonate is a new type of microparticle extensively used in chemical, biological, and industrial sectors. It is commonly found in rocks, marine animal shells, and eggshells.

Living coral reefs consist of rigid "skeletons" inhabited by the tiny coral polyps that built them. A new research project aims to restore damaged reefs faster than ever, utilizing 3D-printed ...

A chemical boundary in the deep sea may have helped shape abyssal ecosystem composition based on body type. The discovery has implications for how these communities could be affected by climate ...

The fast and targeted delivery of drugs could soon be made easier. Microcontainers for medical substances can be produced in different sizes using calcium carbonate microspheres as templates, new ...
