Re-examining longstanding beliefs about the physics of lasers, engineers have shown that carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude.
Using a new nanoscale structure, the researchers, led by electrical engineering professor Stephen Chou, increased the brightness and efficiency of LEDs made of organic materials (flexible carbon-based sheets) by 57 percent.
The team's findings are part of an effort to answer fundamental questions about atomic behavior by creating a device that can simulate the behavior of subatomic particles. Such a tool could be an invaluable method for answering questions about atoms and molecules that are not answerable even with today's most advanced computers.
Princeton researchers have demonstrated that bubbles bursting at the surface of a liquid don't just spray particles upward but also push some down into the liquid -- a finding with potentially broad industrial uses.
Leaders from industry and academia met at Princeton University to discuss three big questions surrounding the broad theme of "water": infrastructure, the water/energy nexus, and industrial water.
Solar electricity installations and other distributed sources of electric power present increasingly pressing questions for public utilities, regulators and consumers, according to organizers of a recent roundtable meeting co-sponsored by Princeton E-ffiliates Partnership.
Graduate student Vikram Pansare took top honors at the Keller Center's 9th annual Innovation Forum, Feb. 26, with his pitch for producing a "Janus particle" capable of driving advances in pharmaceuticals, electronics, oil exploration and other fields.
Increasing the reliability of New Jersey's emerging solar power network and improving the durability of an environmentally-friendly type of concrete are among the research projects awarded funding this year by the Princeton E-ffiliates Partnership.
Michael Schwartz, the Gerhard Andlinger Visiting Professor in Energy and the Environment, stepped to the front of the class with a question. Could market forces drive a sustained movement away from fossil fuels?
Professor Alain Kornhauser has been working with New Jersey legislators to make the state more welcoming to automated vehicle technology. Proponents want to change regulations to ease its introduction and support companies that are developing the technology.
Business leaders and Princeton University scientists gathered for a daylong meeting November 15 to explore solutions to problems of energy and the environment, including adapting to climate change, evolving the electric grid and enabling greener construction.
Princeton researchers representing a wide range of disciplines are helping to propose possible methods to minimize flood risks for shore communities affected by Hurricane Sandy.
Visiting faculty members from other academic institutions, non-profits and industry, spend time teaching and participating in research at Princeton, bringing fresh ideas and initiatives.
The Princeton chapter of Engineers Without Borders (EWB-PU) travels to La Pitajaya, Peru, to construct the first phase of a potable water system.
