José Andrade has got the dirt on dirt. An associate professor of civil and mechanical engineering at Caltech, Andrade will discuss how the actions of a few grains of sand can affect landslides, earthquakes, and even Mars rovers. He will be speaking at 8:00 p.m. on Wednesday, November 28, 2012, in Caltech's Beckman Auditorium. Admission is free.

In order to build the next generation of nuclear reactors, materials scientists are trying to unlock the secrets of certain materials that are radiation-damage tolerant. Now Caltech researchers have brought new understanding to one of those secrets—how the interfaces between two carefully selected metals can absorb, or heal, radiation damage.

David G. Goodwin, professor of mechanical engineering and applied physics, emeritus, passed away at his home in Pasadena on Sunday, November 11, 2012, after a five-year battle with brain cancer and a struggle with Parkinson's disease that began in 1998. He was 55 years old.

Caltech engineers and scientists often work at the frontiers of science—pushing the limits of what is known and what is possible. Now, with its eighth annual Breakthrough Awards, Popular Mechanics magazine is recognizing two projects that fall into this category and in which Caltech faculty members have played major roles—the development of ultralight micro-lattices by materials scientist Julia Greer and colleagues, and the Voyager 1 and 2 missions, whose project scientist, physicist Ed Stone, has been at Caltech for the missions' entire 35-year ride.

In the continual quest for better thermoelectric materials—which convert heat into electricity and vice versa—researchers have identified a liquid-like compound whose properties give it the potential to be even more efficient than traditional thermoelectrics.

Caltech chemists have developed a hypothesis to explain strange behavior of high-temperature superconductors—copper oxides, or cuprates, that conduct electricity without a shred of resistance at temperatures much higher than other superconducting metals.

Julia Greer, assistant professor of materials science and mechanics at Caltech, is part of a team of researchers who have developed the world’s lightest solid material, with a density of just 0.9 milligrams per cubic centimeter, or approximately 100 times lighter than Styrofoam™. Though the material is ultra-low in density, it has incredible strength and absorbs energy well, making it potentially useful for applications ranging from battery electrodes to protective shielding.

They shrink when you heat 'em. Most materials expand when heated, but a few contract. Now engineers at the California Institute of Technology (Caltech) have figured out how one of these curious materials, scandium trifluoride (ScF3), does the trick—a finding, they say, that will lead to a deeper understanding of all kinds of materials.
