Latest Patents

Kühn holds a patent for the invention titled "Hyperpolarization of lithium and other nuclei." This invention concerns a method for hyperpolarizing lithium atoms in a mixture by optically pumping atoms of a first type or alkali metal in a sampling cell. The process involves spin exchange between the optically pumped electron of the alkali metal and the lithium atom electron. The lithium atoms are oxidized into Li ions and accumulated. The nuclear spin polarization of the Li ions can be transmitted to the nuclear spin of an anion. This method allows for the production of hyperpolarized nuclei such as carbon, phosphorus, or silicon in solid or liquid phases, in large amounts and at high polarizing levels.
