Methods to Resist Shear- and Gravity-Driven Drainage of Liquid-Infused Surfaces

Princeton Docket # 15-3089-1Researchers at Princeton University, Department of Mechanical and Aerospace Engineering, have proposed an improvement to the current design and fabrication of liquid-infused surfaces. Rough or patterned surfaces, when chemically treated and infused with a lubricating, superhydrophobic liquid, have been shown to repel liq...

Surfaces for Drag Reduction

Princeton Docket # 15-3149-1Researchers at Princeton University, Department of Mechanical and Aerospace Engineering, have developed a method to reduce the drag on solid objects opposed to fluid flow. Most liquid repellent surfaces are superhydrophobic, which contain pockets of air within surface roughness. Traditional air-water drag reduction surfa...

Fast Response Humidity Sensor

Fast Response Humidity Sensor Princeton Docket # 14-2947 Researchers in the Department of Mechanical and Aerospace Engineering at Princeton University have developed a fast response humidity sensor. Conventional humidity sensors rely on principles such as radiation absorption or capacitance of the air. This new sensor produces high frequency humid...
