Experiments Settle Long-Standing Debate about Mysterious Array Formations in Nanofilms

05-19-11

Sandra M. Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and colleagues' experiments have confirmed which of three possible mechanisms is responsible for the spontaneous formation of three-dimensional (3-D) pillar arrays in nanofilms (polymer films that are billionths of a meter thick). "My ultimate goal is to develop a suite of 3-D lithographic techniques based on remote, digital modulation of thermal, electrical, and magnetic surface forces," Troian says. Confirmation of the correct mechanism has allowed her to deduce the maximum resolution or minimum feature size ultimately possible with these patterning techniques. [Caltech Press Release]

Professor Blanquart Receives NSF CAREER Award

02-25-11

Guillaume Blanquart, Assistant Professor of Mechanical Engineering, has been awarded the National Science Foundation's (NSF) Faculty Early Career Development (CAREER) Award for his proposal entitled "Towards understanding and modeling turbulent buoyant flows". The aim of the project is to understand the complex interactions between turbulent fluid mechanics and Rayleigh-Taylor instabilities. These phenomena commonly occur in nature such as in supernova explosions, under water hot-vents, and fires. They are also encountered in many engineering applications such as in Inertial Confinement Fusion.

Caltech Receives $10 Million in Gifts to Help Launch New Terrestrial Hazard Center

09-15-10

The Terrestrial Hazard Observation and Reporting Center (THOR) has been launched in an effort to find ways to minimize the damage caused by natural hazards. THOR will span two academic divisions at Caltech, Engineering and Applied Science (EAS) and Geological and Planetary Sciences. "The interdisciplinary and interactive nature of engineering at Caltech allows us to translate scientific knowledge and discovery into applications with direct societal impact," says Ares Rosakis, Theodore von Karman Professor of Aeronautics and Professor of Mechanical Engineering; EAS Chair. "One of the areas of pioneering research and innovation made possible by THOR is seismo-engineering. The boundaries of seismo-engineering are fuzzy ones and lie exactly in the interface between seismology and earthquake engineering. We are delighted to have the opportunity to explore these boundaries." [Caltech Press Release]

Aseismic Slip as a Barrier to Earthquake Propagation

05-06-10

Tectonics Observatory researchers including Nadia Lapusta, Associate Professor of Mechanical Engineering and Geophysics, have explored the effects of aseismic slip in the aftermath of the 2007 Peru earthquake. "This large area of aseismic slip is good news," says Jean-Philippe Avouac, Director of the Tectonics Observatory and Professor of Geology. "It lowers the seismic hazard in that region, and allows us to be a little bit predictive. We cannot tell you when there will be an earthquake, but we can tell you where there is stress buildup, and where there is no stress buildup. Where there is no stress buildup, there will be no seismic rupture. That is where the earthquakes are going to stop." [Caltech Press Release]
