The adsorption behavior of calcium carbonate is an important factor in many processes in nature, industry, and biological systems. We determined and compared the adsorption energies for a series of small molecules of different sizes and polarities (i.e., water, several alcohols, and acetic acid)...

ACE2 exists in two forms: as a transmembrane protein and as a soluble catalytic ectodomain of ACE2. The former undergoes shedding by the tumor necrosis factor (TNF)-α–converting enzyme, in which calmodulin mediates the calcium (Ca)-signaling pathway involved in soluble ACE2 release [4]. A...
Mollusk shells or mineral precipitates that form by the reaction of calcium or other metal ions with carbonate may become buried in geologic strata and eventually release CO2 through volcanic outgassing. Carbon dioxide also exchanges through photosynthesis in plants and through respiration in animals. ...
Not all people have access to safe drinking water. According to a 2017 report by theUnited Nations(UN)World Health Organization(WHO), 2.1 billion people lack access to a safe and reliable drinkingwater supplyat home. Eighty-eight percent of the four billion annual cases ofdiarrheareported world...
Calcium is a soft, white metal that oxidizes quickly in the air and interacts with water. It has a bluish-gray appearance. It is the third most common metal on the planet, after iron and aluminum, and the fifth most abundant element in the crust of the Earth. Calcium carbonate is the...
