Abstract
Devices and methods employ a solid-based medium that serves as a magnetic sealant, a lubricant, a bearing, an electrical or thermal conductor, singly or in combination. Included are devices wherein the solid-based medium is retained in a selected position using a magnetic field. In particular, the solid-based medium is either magnetically coupled to the magnetic field or is contained within a cavity sealed by a magnetic seal. In one group of embodiments, the solid-based medium comprises molecules having a molecular structure wherein one element of the structure is a cage or tube, as in fullerenes or met-cars. Such molecules are particularly useful in all of the devices of the present invention because of their exceptional stability and resilience. These properties ensure good performance in corrosive and/or vacuum environments and over a longer lifetime than is possible with conventional media.
