Undergrads help with lunar habitat research

At Purdue Engineering, you can get involved in research, even in your very first year. FYE students Shantanu Sinha and Nathan Stonitsch joined Prof. Davide Ziviani in his project of cooling a lunar habitat simulator, as part of the Resilient Extra Terrestrial Habitat (RETH) Institute at Herrick Labs.

The history of acoustic source localization

The science of locating sound has come a long way... from tin cans, to holographic microphone arrays. In this special publication from the National Academy of Engineering, Purdue acoustics experts Yangfan Liu, Stuart Bolton, and Patricia Davies discuss the history and future of acoustic source localization.

Frank Lee: Accidental Astronaut

Frank Lee is probably the only refrigeration technician in history to perform his job in zero gravity! After 25 years of service as an engineering technician (on the ground) at Herrick Labs, Frank helped to test a new zero-gravity refrigerator prototype for NASA by embarking on a series of parabolic test flights.

Bring the outdoors in: The energy-efficient method for using 100% outdoor air in buildings

A key lesson from the COVID pandemic is the inherent risk of spreading disease through indoor air recirculation. One way to mitigate that risk is to incorporate outdoor air; however, dehumidifying that air requires huge amounts of energy. Purdue University engineers have proposed a system that combines new membrane technology with the latest HVAC systems, to make 100% outdoor air systems economically feasible – especially in warm, humid climates.

Fridge tested in zero gravity

Standard refrigerators use vapor compression to cool down your food. But in space, there is no gravity to keep vapors and liquids secure. Purdue researchers have worked with NASA, Air Squared, and Whirlpool to create a prototype fridge that works in zero gravity, preserving food for potential long-term space flights.

Shirley Dyke featured in "For All Mankind" podcast

In the Apple TV+ series "For All Mankind," both the US and Russia have built bases on the Moon. But how realistic can that be? The official Apple TV+ podcast talked to Shirley Dyke, who researches resilient extraterrestrial habitats at Purdue, and is building a physical testbed at Herrick Labs.

Ride the wave: soliton resonance may enable mechanical energy harvesting

Energy harvesting – creating electrical energy from cars driving over a road, or people walking on a bridge – has long been theorized as a potential source of sustainable electricity. But due to the physical properties of those vibrations, implementing the process has been largely infeasible. Now, Andres Arrieta has proposed using metamaterials as physical frequency converters, potentially bringing us a step closer to harvesting the energy of those vibrations.
