New annealing method unlocks stable, high-efficiency organic solar cells
Science China PressPeer-Reviewed Publication
Constructing efficient and stable organic solar cells is the prerequisite toward organic photovoltaics with practical applications. A research team from China has developed a vacuum-assisted thermal annealing method for organic solar cells, which optimizes the active layer and realizes a “p-i-n” structure. Achieving a maximum power conversion efficiency of 20.5% and an extrapolated lifetime exceeding 54,000 hours, providing a practical approach to overcoming the trade-off between efficiency and stability.

New study confirms Nanotyrannus holotype was distinct species from T. rex
University of Nebraska-LincolnPeer-Reviewed Publication
New research on the holotype skull further moves a decades-long scientific debate toward a conclusion — the Nanotyrannus, a teacup variation of the T. rex, did exist.

‘Free-range’ dinosaur parenting may have created surprisingly diverse ancient ecosystems
University of MarylandPeer-Reviewed Publication
New University of Maryland research suggests that dinosaur parenting strategy fundamentally reshaped the Mesozoic world, with “latchkey kid dinosaurs” filling ecological niches their parents did not.
