Untangling the Heat Paradox Along Major Faults

03-12-21

Nadia Lapusta, Lawrence A. Hanson, Jr., Professor of Mechanical Engineering and Geophysics, and graduate student Valère Lambert, seek to explain the size of the forces acting on "mature faults"—long-lived faults along major plate boundaries like the San Andreas Fault in California—in an effort to better understand the physics that drive the major earthquakes that occur along them. Understanding the physics that govern major earthquakes on different types of faults will help generate more accurate forecasts for earthquake threats. "We have a lot of data from large earthquakes along subduction zones, but the last really major earthquakes along the San Andreas were the magnitude-7.9 Fort Tejon quake in 1857 and the magnitude-7.9 San Francisco Earthquake in 1906, both of them before the age of modern seismic networks," Lapusta says.

Student-Led Moon Dust Shield Team Named Finalist in NASA Competition

02-16-21

As astronauts walk across the moon, land spacecraft on its surface, drive lunar rovers around, or complete other astronaut tasks, they kick up the dust, and that is a problem because it can cause premature wear on mechanical parts, damage to seals, and may pose a health risk for the people breathing it in. "The sun is shining directly on these particles and giving them an electric charge," says third-year Caltech undergraduate student Luis Pabon. "This causes it to stick to the astronaut's suit or to any sensors or cameras that you put out on the moon." The Caltech team's invention, named Habitat Orientable & Modular Electrodynamic Shield (HOMES), tackles the problem of moon dust entering a potential lunar habitat and wreaking havoc within.

Professor Yu-Chong Tai Elected to the National Academy of Engineering

02-09-21

Yu-Chong Tai, Anna L. Rosen Professor of Electrical Engineering and Medical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering, has been elected to the National Academy of Engineering (NAE). Professor Tai was elected for "contributions to microelectromechanical system technologies and parylene-based biomedical microdevices." Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer. Academy membership honors those who have made outstanding contributions to "engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature," and to "the pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education."

Waterman Awardee Dabiri Featured in National Science Foundation Video Profile

12-16-20

The National Science Foundation (NSF) honored John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, with the 2020 Alan T. Waterman Award. The NSF has released a video interview with the Waterman awardees. The Alan T. Waterman Award is given to an outstanding young U.S. scientist or engineer along with a medal and other recognition. "This year's scientific pioneers are innovators who are creatively addressing some of the most challenging scientific questions," said NSF Director Sethuraman Panchanathan. "John Dabiri has looked to the fluid mechanics of sea life for inspiration to build better wind farms that appear to boost efficiency with a much smaller footprint."

Titanium Atom That Exists in Two Places at Once in Crystal to Blame for Unusual Phenomenon

12-07-20

Crystals are usually good at conducting heat. By definition, their atomic structure is highly organized, which allows atomic vibrations—heat—to flow through them as a wave. Austin Minnich, Professor of Mechanical Engineering and Applied Physics, has discovered why a perfect crystal is not good at conducting heat, although it seemingly should be. "We have found that quantum mechanical effects can play a huge role in setting the thermal transport properties of materials even under familiar conditions like room temperature," says Austin Minnich.
