Abstract:

A composition of matter for a layered ionic superconductor comprising a plurality of layers of ions and electronic interaction charges, and having a substantially improved superconducting transition temperature is described. An aspect of the composition includes a first layer comprising a plurality of alkali ions and cesium ions in particular that is adjacent to a second layer comprising a plurality of halogen ions and fluorine ions in particular. The first and second layers contain electronic interaction charges and are separated by a predetermined perpendicular distance. Crystalline structure, ionic properties, superconducting transition temperature, and superfluid density for several embodiments including companion ionic species are described and illustrated. Methods for preparing the several embodiments are provided.

Abstract:

The present invention relates to a method for implantation of Xe isotopes in a matrix for production of I sources that do not shed radioactive atoms. Xe implanted at kV in steel, titanium and gold does not evolve after more than half-lives (380 h) and I from the decay of implanted Xe is equally stable for half-lives (120 d). The matrix having radioxenon implanted is useful as a medical device, for instance as a “seed” for radiotherapeutic uses or in production of stents. Methods of treatment utilizing such devices are also encompassed by the present invention.
