Abstract: A particle-free gold-complex based ink is described wherein a gold carboxylate is complexed with an amine. Upon heating the solution, the gold cation catalyzes the oxidative amidation of the amine with the carboxylate to form a short chain or polymeric amide while simultaneously reducing the gold cation to metallic gold. This method is extremely versatile and allows for both the preparation of pure metallic gold films as well as polymer gold composites with unique properties.

Abstract: A session manager is used to manage selection of a remote host for a session in response to a request that is associated with a user. The session manager uses resource information obtained from remote hosts in advance of the request to determine which remote host to associate with a session for a client. Each remote host performs a resource calculation (configurable) to determine how many processes/sessions it can further accommodate. The remote host sends the results of the resource calculation and other determined resource information to the session manager. The session manager provides the determined remote host to a client device. The client device then directly connects to the determined remote host. A process may be automatically started on the remote host for the client as the user. The session manager may also store and receive information for active and historical processes, remote host status, and remote host configuration.
