Made-to-Order Materials
09-06-13
Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues have created nanostructured, hollow ceramic scaffolds, and have found that the small building blocks, or unit cells, display remarkable strength and resistance to failure despite being more than 85 percent air. The general fabrication technique the researchers have developed could be used to produce lightweight, mechanically robust small-scale components such as batteries, interfaces, catalysts, and implantable biomedical devices.

Solar Decathlon 2013 Construction is Under Way
09-03-13
Last year a group of students in an engineering project course called Introduction to Multidisciplinary Systems Engineering, taught by Professor Melany Hunt, began planning for the Dynamic Augmented Living Environment (DALE), a joint SCI-Arc/Caltech entry in the 2013 Solar Decathlon competition. This type of multidisciplinary and collaborative experience is important for Caltech students, notes Hunt. "Engineering students need experiences in which they design, create, build, and test," she says. "They also should have opportunities in which they work as part of a team. Most engineering projects require multiple perspectives with input coming from a range of individuals with different expertise and vision." [Caltech Release] [LA Times Article]

Compaction Bands in Sandstone are Permeable
06-06-11
José E. Andrade, Associate Professor of Civil and Mechanical Engineering, and colleagues have analyzed X-ray images of Aztec sandstone and revealed that compaction bands are actually more permeable than earlier models indicated. Their paper provides the first permeability calculations based on actual rock samples taken directly from the field in the Valley of Fire, Nevada. They conclude that these formations are not as impermeable as previously believed, and that therefore their ability to trap fluids—like oil, gas, and CO2—should be measured based on 3D images taken from the field.
