Bipolar membranes(BPMs) are a special class of ion-exchange membranes constituted by a cation-and an anion-exchange layer, allowing the generation of protons and hydroxide ions via a water dissociation mechanism. Such unique feature makes bipolar membranes attractive for a variety of applications in many sectors, such as(bio) chemical industry, food processing, environmental protection, and energy conversion and storage, among others.  2, record 1, English, - bipolar%20membrane

Les membranes bipolaires sont un type spécialisé de membrane d'échange d'ions, généralement composée d'une couche d'échange de cations et d'une couche d'échange d'anions, réunies par une fine couche très conductrice, qui permet le clivage de l'eau.  2, record 1, French, - membrane%20bipolaire

... Calcium and Magnesium react with other chemicals in the water. The warm water acts as a catalyst and increases the number of reactions depending on the concentration of calcium and magnesium. The reaction which takes place is the dissociation of calcium hydrocarbonate, formula : Ca(HC0₃) and magnesium hydrocarbonate, formula : Mg(HC0[ susbcript 3]) ₂. Both of these are soluble solids, which means they can dissolve when put in water. When these two soluble salts dissociate, they form carbon dioxide(a gas), which is released from the water, and calcium and magnesium carbonate. These two compounds are not soluble and are therefore taken out of solution. And it is these substances that cause the filmy, fuzzy crud on the glass of your aquarium when the water evaporates.  3, record 2, English, - magnesium%20bis%28hydrogencarbonate%29

San Marcos River Basin. The lithology and the water flow conditions are the major factors that determine the chemical composition of the waters and the hydrogeochemical patterns. We can distinguish the following water types: sodium calcium hydrocarbonate for waters from the sedimentary-effusive rocks, magnesium hydrocarbonate for the waters which originate in the ultrabasic massif, and calcium hydrocarbonate for that waters which flow in the karst areas (at the source, caves, exsurgences and springs from the saturation zone).  4, record 2, English, - magnesium%20bis%28hydrogencarbonate%29
