The project was named C 4 S, which stands for Calcium Carbonate Circulation System for Construction, and led by Professor Takafumi Noguchi, as project manager, with Professor Ippei Maruyama ...

"This is one of the first demonstrations of microbial dissolution of calcium carbonate at a higher pH," said Karrie Weber, professor of biological sciences and Earth and atmospheric sciences.

Hungarian researchers have discovered unique bacterial communities in thermal waters that may help unravel the development of ...

To make concrete, limestone, or calcium carbonate, is mixed with clay and other materials and then calcined at high temperatures, so CO2 is released via the thermal decomposition of calcium carbonate.

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate ...
