Reducing traps increases performance of organic photodetectors
Flexible organic photodetectors (OPDs) have a huge potential for applications in low-cost imaging, health monitoring and near infrared sensing. Credit: Christian Körner Physicists at the Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) discovered that trap states rule the performance of organic photodetectors, ultimately limiting their detectivity. These highly promising results have now […]
How To Manage Performance In A Global Pandemic?
The year of 2020 presented significant upheaval in the lives of millions of workers, suddenly finding themselves within their own four walls more than in the office. 2021 looks set to be more of the same, with lockdowns installed in many nations yet again. When you have employees in a dedicated workplace setting such as […]
Study reveals jellyfish create a ‘virtual wall’ to enhance performance
Image captured in glass filming vessel.

Jellyfish create a ‘virtual wall’ to enhance performance — ScienceDaily
New research led by the University of South Florida has uncovered one of the reasons jellyfish have come to be known as the “world’s most efficient swimmer.” Brad Gemmell, associate professor of integrative biology, found jellyfish produce two vortex rings, which are donut-shaped bodies of fluid underneath their translucent bodies, that spin in opposite directions. […]
Flag leaves could help top off photosynthetic performance in rice
The flag leaf is the last to emerge, indicating the transition from crop growth to grain production. Photosynthesis in this leaf provides the majority of the carbohydrates needed for grain filling–so it is the most important leaf for yield potential. A team from the University of Illinois and the International Rice Research Institute (IRRI) found […]

Machine learning guarantees robots’ performance in unknown territory — ScienceDaily
A small drone takes a test flight through a space filled with randomly placed cardboard cylinders acting as stand-ins for trees, people or structures. The algorithm controlling the drone has been trained on a thousand simulated obstacle-laden courses, but it’s never seen one like this. Still, nine times out of 10, the pint-sized plane dodges […]
Zinc-ion hybrid capacitors with ideal anions in the electrolyte show extra-long performance — ScienceDaily
Metal-ion hybrid capacitors combine the properties of capacitors and batteries. One electrode uses the capacitive mechanism, the other the battery-type redox processes. Scientists have now scrutinized the role of anions in the electrolyte. The results, which have been published in the journal Angewandte Chemie, reveal the importance of sulfate anions. Sulfate-based electrolytes gave zinc-ion hybrid […]
