Researchers showed that size-controlled lignin nanoparticles made from alkali and kraft lignins can improve enhanced oil recovery by lowering interfacial tension and shifting sandstone and carbonate ...

Some species of fig trees store calcium carbonate in their trunks—essentially turning themselves (partially) into stone, new research has found. The team of Kenyan, U.S., Austrian, and Swiss ...

Carbonate analysis through X-ray diffraction (XRD) techniques has been well documented, and research into both carbonates and clays dates back many decades. An abudance of research has been published ...

Carbon mineralization is a process by which gaseous carbon dioxide reacts chemically with certain rock types and transforms into solid carbonate minerals. This natural process is an essential part of ...

Earth's largest mass extinction occurred about 252 million years ago, wiping out the majority of marine and terrestrial life, disrupting the global carbon cycle for several hundred thousand years, and ...

CNOOC made 'the first major exploration breakthrough in ultra-deepwater carbonate rocks offshore China' after drilling about 9,850 feet deep into the Pearl River Mouth Basin. CNOOC Ltd. announced ...

The rocks in this part of the world have a special ability: They can turn carbon dioxide into stone. The rocks here in Oman are special, this scientist says. They remove planet-warming carbon dioxide ...
