Group expands study of PCM as way to enhance concrete pavement durability

In a project funded by the National Science Foundation, an Arizona State University engineer has been examining the use of phase change materials to reduce or prevent temperature-related cracks in concrete pavement. 

Narayanan NeithalathNarayanan Neithalath and colleagues at UCLA will now expand their work in collaboration with Delft University of Technology in the Netherlands, the Swiss Federal Institute for Materials Science and the Tecnalia Research and Innovation organization in Spain.

The international collaboration has been awarded $1.6 million to find out whether concrete solutions containing a phase change material can significantly enhance the durability of concrete pavements and bridge decks. 

“We are impregnating PureTemp in lightweight aggregates for this project,” said Neithalath, an associate professor of civil, environmental and sustainable engineering in ASU’s Ira A. Fulton Schools of EngineeringEncapsys LLC of Appleton, Wis., is providing microencapsulation services.

“We know how the materials perform under laboratory conditions,” Neithalath said. “Now we have to see if it holds up when applied at larger scales and real-life loading and environmental conditions.” 


$100,000 in prize money awaits winners of FLoW business plan competition

Entries are being sought for the 2016 FLoW program, a business plan competition for American university students and recent graduates focused on clean-tech and sustainability. Mentors will be assigned to help contestants develop their ideas and refine their pitches. $100,000 in prize money is available to winners. Submissions are due March 7, 2016.

Axiom Exergy took first place in 2015 with a refrigeration battery technology designed to help the food industry reduce energy costs. The battery charges by freezing tanks of salt water at night, when electricity is cheaper, and then provides refrigeration throughout the day. Axiom, led by a Stanford University team, won $75,000.


SGOCO Group Ltd., a Chinese company that develops and distributes flat-panel displays, has agreed to buy Boca International Ltd. of Hong Kong. Boca develops and manufactures thermal energy storage systems incorporating phase change material.
