Microfluidic Tissue Engineering and Bio‐Actuation
Advanced Materials, Volume 34, Issue 23, June 9, 2022., 2022 Microfluidics enables the engineering of biological tissues through micro‐precision control over the cell microenvironment, fabrication of cell‐laden matrices, and distribution of fluids to perfuse 3D tissue constructs. In particular, microfluidically‐advanced functional muscle tissues can be used as performant actuators in the next generation of bio ...

Low Cost Catalysts for Hydrazine Monopropellant Thrusters [PDF]
45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2009 Hydrazine monopropellant engines are widely used in space missions; mainly in reaction control systems. The most widely used catalyst is the aluminum oxide supported iridium. It is also very expensive. The cost of the catalyst weights heavily, especially in the high thrust, short life thrusters used for roll control of launch vehicles. In this paper we

Monopropellant Thruster Exhaust Plume Contamination Measurements [PDF]
, 1977 The potential spacecraft contaminants in the exhaust plume of a 0.89N monopropellant hydrazine thruster were measured in an ultrahigh quartz crystal microbalances located at angles of approximately 0 deg, + 15 deg and + or - 30 deg with respect to the nozzle centerline. The crystal temperatures were controlled such that the mass adhering to the crystal
