New structure could produce efficient semiconductor laser sources
University of Wisconsin–Madison researchers have achieved a nanoscale laser structure they anticipate will produce semiconductor lasers in the next two years that are more than twice as efficient as current continuous-wave lasers emitting in the mid-infrared.
Middle East air-quality study bridges borders
An unprecedented effort to collect air pollution data in the Middle East has united researchers in a region mired in conflict.
New material could efficiently power tiny generators
To power a very small device like a pacemaker or a transistor, you need an even smaller generator. The components that operate the generator are smaller yet, and the efficiency of those foundational components is critical to the performance of the overall device.
Carbon nanotubes may cheaply harvest sunlight
A new alternative energy technology relies on the element most associated with climate change: carbon.
Models begin to unravel how single DNA strands combine
Using computer simulations, a team of University of Wisconsin–Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix.
Smaller isn’t always better: Catalyst simulations could lower fuel cell cost
Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin–Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality.
Research aims to cool runoff to protect coldwater streams
The ocean of stormwater that flows off of the sun-baked urban landscape is packing heat, and trout are starting to feel it.
