Abstract: Catalysts for NH3 cracking and/or synthesis generally include barium calcium aluminum oxide compounds decorated with ruthenium, cobalt, or both. These catalysts can be bonded to a metal structure, which improves thermal conductivity and gas conductance.

Abstract: This invention relates to a supported catalyst for synthesizing ammonia (NH3) from nitrogen gas (N2) and hydrogen gas (H2), method of making the support, and methods of decorating the support with the catalyst.

Abstract: A method and device is provided for autotransfusion of blood during surgery. The shed blood is retrieved from the surgical field via a receiving vessel located within a vacuum chamber and under less vacuum than the vacuum applied to the chamber. The vacuum in the receiving vessel draws blood from the surgical field into the receiving vessel where it is first collected and then passed to a second vessel. The blood is transferred from the second vessel to the patient during reinfusion. Suitable filters are provided for removing any blood clots or bits of tissue before the blood is reinfused.
