Briefs: Lighting
Now, a team from the Max Planck Institute for Polymer Research has developed a new material concept that could allow efficient blue OLEDs with a strongly simplified structure. Read on to learn more.
Application Briefs: Robotics, Automation & Control
In partnership with Point One, Civ Robotics is ensuring that precise construction layouts won’t be at odds with efficiency. Land surveying is a critical stage in the construction layout process, during which workers use various forms of global navigation satellite systems (GNSS) to mark specific locations for builders. Read on to learn more.
Briefs: Imaging
Mimicking the easy, instantaneous image processing power of the human eye, Penn State electrical engineering researchers created a metasurface, an optical element akin to a glass slide that uses tiny nanostructures, placed at different angles to control light.
Technology & Society: Green Design & Manufacturing
Penn State researchers are exploring green stormwater infrastructure to manage severe urban flooding and pollution. They are studying ways to improve the existing green stormwater infrastructure in Lancaster, PA, as a pilot project for other cities as well.
