National Science Foundation Fundamental research in phonon scattering helps researchers design graphene materials for applications Graphene, a one-atom-thick form of the carbon material graphite, has been hailed as a wonder material--strong, light, nearly transparent and an excellent conductor of electricity and heat--and it very well may be. But a number of practical challenges must be overcome before it can emerge as a replacement for silicon and other materials in microprocessors and...

Engineers have developed a technique that saves energy and servicing costs by indicating when air conditioners are low on refrigerant, preventing the units from working overtime.The new "virtual refrigerant charge sensor" is particularly practical for automotive air conditioners, which tend to leak refrigerant more than other types of units, and also for household central air conditioning units, said James Braun, a professor of mechanical engineering.Maintaining the proper "charge," or amount...

Researchers at Purdue University are developing a miniature refrigeration system small enough to fit inside laptops and personal computers, a cooling technology that would boost performance while shrinking the size of computers. Unlike conventional cooling systems, which use a fan to circulate air through finned devices called heat sinks attached to computer chips, miniature refrigeration would dramatically increase how much heat could be removed, said Suresh Garimella, the R. Eugene and...
