Sep. 10, 2024 Researchers have designed and synthesized a new organic semiconductor for organic solar cells (OSCs). By adding specific side units to their structure, they achieved separation between the frontier molecular orbitals, leading to lower exciton binding energy and increased power conversion efficiency. This tuning of the design of an acceptor ...

Sep. 13, 2024 The common practice of building dams to prevent flooding can actually contribute to more intense coastal flood events, according to a new study. By analyzing data and measurements from Charleston Harbor, South Carolina, dating back more than a century, researchers determined that coastal dams don't necessarily mitigate flooding. Dams can either increase or decrease flood risks, depending on the ...

Sep. 12, 2024 Extreme conditions prevail inside stars and planets. The pressure reaches millions of bars, and it can be several million degrees hot. Sophisticated methods make it possible to create such states of matter in the laboratory -- albeit only for the blink of an eye and in a tiny volume. So far, this has required the world's most powerful lasers, and the opportunities for experiments are ...

Sep. 12, 2024 Astronomers have directed NASA's James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For comparison, Earth is approximately 26,000 light-years from the ...
