Understanding precisely how fluid boils in tiny "microchannels" has led to formulas and models that will help engineers design systems to cool high-power electronics in electric and hybrid cars, aircraft, computers and other devices.
Researchers at Purdue University have overcome a major obstacle in reducing the cost of "solid state lighting," a technology that could cut electricity consumption by 10 percent if widely adopted.
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.
Researchers at Purdue's Birck Nanotechnology Center are collaborating with Indian colleagues at the Jawaharlal Nehru Center for Advanced Scientific Research and General Electric Co.'s John F. Welch India Technology Center to launch a center focused on how advancements in nanomaterials can address growing energy needs.

We work on a broad range of problems, primarily involving the transport and conversion of energy carried by electrons, phonons, and photons. We seek to solve problems with high importance to applications in clean energy (e.g., direct energy conversion, hydrogen storage) and in major industrial segments (e.g., micro/nanoelectronics, sensors).
