The stone monuments of Italy's Certosa di Bologna cemetery have stood for more than two centuries as symbols of peace and eternity. But even stone does not last forever. So Enrico Sassoni, a visiting postdoctoral research associate in Princeton's Department of Civil and Environmental Engineering, is working to protect the marble monuments and even make them stronger.
Turning municipal solid waste into fuel and reducing greenhouse gases emitted in making concrete are the first two innovations funded by the recently established Princeton Energy and Environment Corporate Affiliates Program.
Princeton engineers are designing an underground experimental facility in a defunct South Dakota gold mine to test what would happen if carbon dioxide stored underground were to leak toward the surface.
Burning oil and coal, which are rich in carbon, releases the greenhouse gas carbon dioxide. Until alternative fuels become mainstream, one viable option to cut carbon emissions is to capture the gas and inject it into sediments deep underground, according to Princeton's Michael Celia *79, chair of civil and environmental engineering.
Five engineering faculty members were among ten Princeton University scientists who teamed up with local sculptors, architects and landscape architects to create the phenomenon known as Quark Park.
