Sodium zirconium cyclosilicate, sold under the brand name Lokelma, is a medication used to treat high blood potassium. [5] Onset of effects occurs in one to six hours. [5] It is taken by mouth. [5] Common side effects include swelling and low blood potassium. [5] Use is likely safe in pregnancy and breastfeeding. [5]
Polystyrene sulfonate is usually supplied in either the sodium or calcium form. It is used as a potassium binder in acute and chronic kidney disease for people with hyperkalemia (an abnormally high blood serum potassium level). [3]
The stable nuclides of lithium, beryllium, and boron found on Earth are thought to have been formed by the same process as the cosmogenic nuclides but at an earlier time in cosmic ray spallation predominantly before the Solar System's formation, and thus they are by definition primordial nuclides and not cosmogenic.

Cascade reactions are often key steps in the efficient total synthesis of complex natural products. The key step in Heathcock's synthesis of dihydroprotodaphniphylline features a highly efficient cascade involving two aldehyde/amine condensations, a Prins-like cyclization, and a 1,5-hydride transfer to afford a pentacyclic structure from an acyclic starting material.
Compacted oxide layers can form due to sliding at low temperatures and offer some wear protection; however, in the absence of heat as a driving force (either due to frictional heating or higher ambient temperature), they cannot sinter together to form more protective 'glaze' layers.
Google is complying with President Donald Trump’s executive action that renamed the Gulf of Mexico to the Gulf of America. Soon, the name change will appear on Google Maps.
Minerals bond grains of sediment together by growing around them. This process is called cementation and is a part of the rock cycle. Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains. The new pore-filling minerals form "bridges" between original sediment grains ...
