This method attempts to reduce the amount of residual stress and aberration that occurs by eliminating the forceful bending of such standard devices. This invention solves a difficult problem faced by those wishing to create a crystal surface, with even modest curvature, without causing non-uniform residual surface stresses.

The corrosion behaviors of materials must be addressed to develop both durable and degradable alloys for use in various applications and predict their long-term performance in service conditions.

This invention comprises an electrochemical test method that imposes the chemical and redox conditions and allows the material surface representing the long-term performance of durable or degradable materials to develop in various applications.

The invention provides a single radiator cooling system for use in hybrid electric vehicles, the system comprising a surface in thermal communication with electronics, and subcooled boiling fluid contacting the surface. The invention also provides a single radiator method for simultaneously cooling electronics and an internal combustion engine in a hybrid electric vehicle, the method comprising separating a coolant fluid into a first portion and a second portion; directing the first portion to the electronics and the second portion to the internal combustion engine for a time sufficient to maintain the temperature of the electronics at or below 175° C.; combining the first and second portion to reestablish the coolant fluid; and treating the reestablished coolant fluid to the single radiator for a time sufficient to decrease the temperature of the reestablished coolant fluid to the temperature it had before separation.

A process for forming a palladium or palladium alloy membrane on a ceramic surface by forming a pre-colloid mixture comprising a powder palladium source, carrier fluid, dispersant and a pore former and a binder. Ultrasonically agitating the precolloid mixture and applying to a substrate with an ultrasonic nozzle and heat curing the coating form a palladium-based membrane.
