GEOLOGISTS owe a debt of gratitude to Dr. Grabau for the preparation and publication of this volume. It is a mine of information on the occurrence and characters of deposits of mineral salts, ...

When it comes to knowing what actually lies deep inside the Earth, diamonds are a geologist’s best friend. The diamond bearing the telltale mineral inclusion came from a Botswana mine and formed at ...

For the first time, a high-pressure calcium silicate perovskite (CaSiO 3) has been identified as a naturally occurring mineral from Earth’s lower mantle, researchers report. The newly discovered ...

A study was made of the use of magnesium silicates as adsorbents for phosphate present in water. It was found that the phosphate absorption capacity for the minerals and the alumina studied is in the ...

Stanford University chemists have developed a practical, low-cost way to permanently remove atmospheric carbon dioxide, the main driver of global warming and climate change. The new process uses heat ...

An important aspect of Raman effect is that it is extremely sensitive to even small amount of differences in chemical structures. Even if all vibrations are not observed with Raman spectroscopy, ...

Chemists at Stanford University have developed a low-cost way to remove carbon dioxide (CO) from the atmosphere using an ...

"The process acts as a multiplier," Kanan said. "You take one reactive mineral, calcium oxide, and a magnesium silicate that is more or less inert, and you generate two reactive minerals." As a quick ...
