Shape Memory Alloys for Bridges

Virginia Heffernan - December 30, 2009

Bridges in earthquake-prone regions may one day benefit from the super-elastic qualities of shape memory alloys (SMAs) made of nickel and titanium.

New research from the University of Nevada in Reno suggests that by integrating SMAs into bridge columns, civil engineers can reduce the damage to bridges caused by earthquakes while increasing the capital cost of the bridge by only about 4%.

A catalyst for sustainable operations
Nickel-containing catalysts are widely used in the refining and petrochemical industries worldwide. At end-of-life, catalysts are either sent to landfill or sent for recycling to recover the valuable metals they contain. Refineries in Kuwait are changing the way they handle spent catalysts.
