Calcium-dependent oligomerization of CAR proteins at …

Drought and salinity are the major threats to crop productivity at a worldwide scale. A fundamental portion of the plant response to these environmental stresses occurs at the cell merane, where the molecular machinery to preserve cell turgor and the appropriate balance of intracellular ions is found. The C2-domain ABA-related (CAR) family of proteins contributes to these processes by

Métal — Wikipédia

Une fois extraits des mines, les minerais sont traités pour isoler le métal recherché, le plus souvent par réduction chimique ou électrolytique.La pyrométallurgie utilise des températures élevées pour convertir les minerais en métaux bruts, tandis que l''hydrométallurgie passe par au moins une étape où le métal est solvaté dans l''eau.

Faraday''s laws of electrolysis - Wikipedia

Faraday''s laws of electrolysis are quantitative relationships based on the electrochemical research published by Michael Faraday in 1833. They state that the amount of material produced at an electrode (or liberated from it) during an electrochemical reaction is directly proportional to the total conducted charge or, equivalently, the average current multiplied by the total time.

Precipitation (chemistry) - Wikipedia

Precipitation defined as the creation of a solid from a solution. When the reaction occurs in a liquid solution, the solid formed is called the ''precipitate''. The chemical that causes the solid to form is called the ''precipitant''. Without sufficient force of gravity to bring the solid particles together, the precipitate remains in suspension.
