Smart windows equipped with controllable glazing can augment lighting, cooling and heating systems by varying their tint, saving up to 40 percent in an average building’s energy costs. These smart windows require power for operation, so they are relatively complicated to install in existing buildings. But by applying a new solar cell technology, researchers at […]
Wave of the Future: Terahertz Chips a New Way of Seeing Through Matter
Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, have long required elaborate and expensive equipment to use. Now, researchers at Princeton University have drastically shrunk much of that equipment: moving from a tabletop […]
New Microchip Demonstrates Efficiency and Scalable Design
Princeton University researchers have built a new computer chip that promises to boost performance of data centers that lie at the core of online services from email to social media. Data centers — essentially giant warehouses packed with computer servers — enable cloud-based services, such as Gmail and Facebook, as well as store the staggeringly […]
Nanotechnology Leads to Better, Cheaper LEDs
Princeton University researchers have developed a new method to increase the brightness, efficiency and clarity of LEDs, which are widely used on smartphones and portable electronics as well as becoming increasingly common in lighting. Using a new nanoscale structure, the researchers, led by electrical engineering professor Stephen Chou, increased the brightness and efficiency of LEDs […]
Strange Physics Turns Off Laser
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter. The finding by a team of researchers at Vienna University of Technology and Princeton University, could lead to new ways to manipulate the interaction of electronics […]
