Phys.org / OLEDs can now switch light's handedness with an electrical signal
Researchers from the University of Oxford have for the first time discovered an approach to electrically switch organic LEDs (OLEDs) to emit either left- or right-handed circularly polarized light without changing the light-emitting ...
Tech Xplore / The world's most efficient solar cell: Chinese researchers explain how they designed and built it
Earlier in 2025, Chinese solar manufacturer Longi announced it had built the world's most efficient solar cell. The hybrid interdigitated back-contact (HIBC) cell achieved 27.81% efficiency, which was verified by Germany's ...
Phys.org / 5 reasons the COP30 climate conference failed to deliver on its 'people's summit' promise
As the sun set on the Amazon, the promise of a "people's Cop" faded with it. The latest UN climate summit—known as Cop30, hosted in the Brazilian city of Belém—came with the usual geopolitics and the added excitement ...
