Purdue and Sandia researchers uncover how common clay minerals can capture carbon dioxide directly from air, offering a low-cost climate solution.

One of Earth's most common nanomaterials is facilitating breakthroughs in tackling climate change: clay. In a new study ...

The researchers focused on a specific smectite called saponite. They examined how saponite handles carbon dioxide and water vapor competing for space in the clay's tiny internal pores. Unlike past ...

Here, a synthetic saponite clay, which is oriented in a film, is used as a confining medium in the bilayer state. It confines two water layers between negatively charged planes, the charge of which is ...

As a result, seven hydrous minerals were quantitatively retrieved, e.g. actinolite, montmorillonite, saponite, jarosite and so forth, and the total concentration of all hydrous minerals was as high as ...

The mineralogical approach showed that the clay minerals, produced by the weathering of the primary minerals (amphiboles and plagioclases), or filling the fissure network were made up of smectites ...
