Ordinary materials, fantastic opportunities

For Michael Demkowicz, some of the greatest scientific mysteries and major engineering opportunities lie in everyday materials. "Structural materials are sometimes seen as low-tech," he says. "Who thinks about steel, who ...

Retrofitting earthquake protection could save lives

Whether or not a building collapses and claims many lives during an earthquake is a matter of structure and statistics, according to researchers in Turkey. Writing in the International Journal of Emergency Management, civil ...

New report charts path toward superior earthquake recovery

For the last century, seismic building codes and practices have primarily focused on saving lives by reducing the likelihood of significant damage or structural collapse. Recovery of critical functions provided by buildings ...

CCNY landscape architect offers storm surge defense alternatives

The flooding in New York and New Jersey caused by Superstorm Sandy prompted calls from Gov. Andrew Cuomo and other officials to consider building storm surge barriers to protect Lower Manhattan from future catastrophes. But, ...

Super light dampers for low tones

A team of Empa acoustic researchers has built macroscopic crystal structures that use internal rotation to attenuate the propagation of waves. The method makes it possible to build very light and stiff materials that can ...

Soot forensics: Carbon fingerprints reveal curved nanostructure

Researchers have moved one step closer to reducing air pollution from engines by imaging soot nanoparticles to reveal their unique signatures. The nanoparticle structures are like fingerprints, revealing curved fullerene-like ...
