Cement-based cementitious materials present an alkaline environment and mainly exist in the form of Ca(OH)2. Phosphogypsum, as a retarder of cementitious materials, is often added to cement instead of gypsum, and the fluorine by-product of phosphogypsum ...

pH sensing via bicarbonate-regulated ‘soluble’ adenylyl cyclase (sAC)
Soluble adenylyl cyclase (sAC) is a source of the second messenger cyclic adenosine 3',5' monophosphate (cAMP). sAC is directly regulated by bicarbonate (HCO3-) ions. In living cells, HCO3- ions are in nearly instantaneous equilibrium with carbon

Renal bicarbonate reabsorption during bicarbonate loading
To examine bicarbonate reabsorption at different GFR's, we varied the renal perfusion pressure in anesthetized dogs after inhibiting autoregulation by expanding extracellular volume and infusing ethacrynic acid. At a plasma bicarbonate concentration (PHCO3) of 28 +/- 1 mM, bicarbonate reabsorption varied in proportion to GFR (glomerulotubular balance).

Coupled nitrogen transformation and carbon sink in the karst aquatic system: a review
Carbonate bedrock regions represent that 14% of Earth's continental surface and carbon (C) sink in karst water plays an important role in the global C cycle due to the CO2 consumption during carbonate mineral weathering.
