Abstract: An anion exchange membrane includes a porous structural framework and bismuth atoms bonded to pore surfaces of the porous structural framework. Each bismuth atom is bonded to a pore surface by way of one or two oxygen atoms.

Abstract: A mobile phase including a lithium salt flows through a stationary phase including an oxygenated metal compound with affinity to the lithium salt through a Lewis acid-Lewis base interaction so that the oxygenated metal compound captures the lithium salt through the Lewis acid-Lewis base interaction. An eluent flows through the stationary phase to release the lithium salt captured by the oxygenated metal compound into the eluent. The eluent includes a Lewis base or a Lewis acid that disrupts the Lewis acid-Lewis base interaction between the lithium salt and the oxygenated metal compound. The eluent including the released lithium salt is collected after the eluent flows through the stationary phase.

Abstract: A proton exchange solid support includes a porous polymer network including a polymer. The polymer includes a tetravalent boron-based acid group in a side chain of the polymer, and the tetravalent boron-based acid group includes a boron atom having a negative formal charge. A cation is ionically linked to the boron atom.

Abstract: A boron-containing proton-exchange solid support may include a proton-exchange solid support comprising an oxygen atom and a tetravalent boron-based acid group comprising a boron atom covalently bonded to the oxygen atom.

Abstract: A proton exchange membrane includes a porous structural framework and a boron-based acid group bonded to the porous structural framework. The porous structural framework may be formed of an amorphous or crystalline inorganic material and/or a synthetic or natural polymer.

Abstract: A method for generating alkali metal in a zero oxidation state includes reacting an alkali metal compound having a —S-M substituent, where M is an alkali metal and S is sulfur, with gold in a zero oxidation state to release the alkali metal in the zero oxidation state. For example, an alkali metal alkylthiolate can be reacted with a gold in a zero oxidation state to release the alkali metal in the zero oxidation state. As another example, an alkali metal sulfide can be reacted with gold in a zero oxidation state to release the alkali metal in the zero oxidation state. The alkali metal may be used in various applications including vapor cells, magnetometers, and magnetic field measurement systems.
