Abstract: Nanotubes loaded with materials, such as active species, and methods to load materials into nanotubes are disclosed. The method includes flowing a medium containing the material to be loaded through the interior volume of the nanotube, wherein it is retained, optionally by a crosslinking or polymerization reaction. Flowing the medium occurs under different conditions and processes, including centrifuging and size exclusion methods.

Abstract: A database system is provided that allows for navigation to outgoing links and incoming links. The database system is defined by a plurality of database-oriented projects. Each project has one or more parameters. Each project also has one or more instances thereof. An entry is associated with each parameter in each instance of a project. In a project, a parameter may be defined as being a parameter of a previously defined project. If so, then the parameter is designated as a link to the parameter of the previously defined project. The link designation changes the structure of the database system. The name of a previously defined instance of a previously defined project is entered for the linked parameter entry. When a previously defined instance of a project having at least one linked parameter entry is displayed, an instance of a project having a linked parameter entry may be viewed by selecting the respective link from the display, thereby providing navigation to an outgoing link.
