Abstract: A magnetic photocatalyst composite particle includes a magnetic composition and at least one photocatalyst particle secured to the magnetic composition. The magnetic photocatalyst composite particles can be nano-sized. The magnetic photocatalyst composite particles permit high levels of photocatalytic chemical activity to be combined with controllable particle movement and allow the formation of improved reactors for the treatment of water and air.

Abstract: This invention is directed to a process for forming a sorbent-metal complex. The process includes oxidizing a sorbent precursor and contacting the sorbent precursor with a metallic species. The process further includes chemically reacting the sorbent precursor and the metallic species, thereby forming a sorbent-metal complex. In one particular aspect of the invention, at least a portion of the sorbent precursor is transformed into sorbent particles during the oxidation step. These sorbent particles then are contacted with the metallic species and chemically reacted with the metallic species, thereby forming a sorbent-metal complex. Another aspect of the invention is directed to a process for forming a sorbent metal complex in a combustion system. The process includes introducing a sorbent precursor into a combustion system and subjecting the sorbent precursor to an elevated temperature sufficient to oxidize the sorbent precursor and transform the sorbent precursor into sorbent particles.

Abstract: The present invention employs random electrostatic discharges to stress test electrical machinery, particularly digital computer systems running repetitive diagnostic programs. There is provided an interactive capability which allows the user to determine test duration either in terms of a fixed time or in terms of a specified confidence level, the latter case being one in which the system provides the user with an indication of the run time required. Significant improvements over deterministic "zapping" devices result. The improvement includes solving the equation: ##EQU1## (Where: ##EQU2## as a program step.

Abstract: A system having a computer, test control logic, an electrostatic discharge unit and a high voltage probe unit is provided for performing multiple, random, asynchronous electrostatic discharge testing of machines. The test control logic includes multiple, asynchronous, random, firing logic for controlling the states of a plurality of output lines which send control signals from the computer to the electrostatic discharge unit and the high voltage probe unit. The test control logic allows a user a preference of testing modes through an interactive input graph. The user may specify either a run time experiment or a specific probability of test coverage test.
