Abstract: The present teachings are directed towards a thermolysis method of producing iron-containing nanoparticles by providing an iron-containing component, a colloid stabilizing component, and an amount of water. The iron-containing component, the colloid stabilizing component, and the amount of water form a mixture, which is then heated to a temperature sufficient to form iron-containing nanoparticles, which are then isolated from the mixture. Another method is also provided which involves a repetitive shell growth method of producing iron-containing nanoparticles by providing a first amount of an iron-containing component and a colloid stabilizing component; the iron-containing component and the colloid stabilizing component are then mixed and heated to a temperature sufficient to form iron-containing nanoparticles.

Abstract: A trigger engine and infrastructure for event registration and handling that is reliable, secure and scalable. Transactional authenticated and/or encrypted messages (e.g., via MSMQ) are used to transport events across each server. A stable recovery mechanism is provided wherein the recovery path is nearly identical to the normal path. A trigger engine may concentrate multiple similar requests into a single base request for event notification, and upon receipt of the base event, access tables maintained in the trigger engine to track which client registered for which type of notification. In this manner, only the base event request is registered remotely, reducing the number of events that need to be communicated to remote servers. Identical event requests from clients may also be concentrated into a base event request, and events distributed to those clients when appropriate. Duplicate base event requests are blocked locally and thus only the first such one ever reaches the remote server.
