What PCMs are available for use in catalytic converters?

Ben Welter - Friday, November 21, 2014

Subramanian Sendilvelan of Bharath University in Chennai, India, asks, via ResearchGate: What phase change materials are available at 300˚C for use in catalytic converters? A professor at Chaitanya Bharathi Institute of Technology in Hyderabad suggests a 2012 paper on the use of PCMs in vehicles might be useful in exploring that topic.

The science of phase change: It’s (more) complicated

Ben Welter - Thursday, November 06, 2014

Think you know how phase change works? You might need to rethink that. Researchers at Princeton, Peking University and New York University say the process is a lot more complex than previously known. "This research shows that phase changes can follow multiple pathways, which is counter to what we've previously known," explains Mark Tuckerman, a professor of chemistry and applied mathematics at NYU and one of the study's co-authors. "This means the simple theories about phase transitions that we teach in classes are just not right."
