A late Devonian impact event and its association with a possible extinction event on Eastern Gondwana [PDF]

Evidence from South China and Western Australia for a 365-Ma impact event in the Lower crepida conodont zone of the Famennian stage of the Late Devonian (about 1.5 Ma after the Frasnian/Famennian extinction event) includes microtektitelike glassy ...

Photoaccumulation of Long‐Lived Reactive Electrons in a Microporous Ti(IV) Oxocluster‐Based Metal–Organic Framework for Light and Dark Photocatalysis

Advanced Materials, EarlyView.
The microporous Ti12 oxocluster‐based MOF MIP‐177(Ti)‐LT exhibits effective charge separation and long‐lived photogenerated electrons persisting for hours, as revealed by spectroscopy. These electrons cause reversible color changes and enable dark H2 evolution and water splitting, demonstrating remarkable electron storage and redox capability ...

The artist as a political vandal and moral witness: Lucienne Rickard’s Extinction Studies

Journal of Aesthetics & Culture
Extinction Studies was a years-long, politically motivated artistic event that blurs the boundaries not only between traditional “conservable” visual artwork and ephemeral performance but also between scientific rigour and emotional truth-telling. In the

Perspective: OLED Displays Singing with the Blues

Advanced Materials, EarlyView.
While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.

Aggregation‐Induced Emission Molecular Design for Mitigating Non‐Radiative Energy Loss in Organic Solar Cells

Advanced Materials, EarlyView.
Aggregation‐induced emission strategy is first used to overcome aggregation‐caused quenching in Y‐series acceptors. By integrating tetraphenylethylene, the dTPE exhibits three‐fold PLQY enhancement and significantly suppressed non‐radiative energy loss. An ultra‐low Eloss of 0.130 eV and a record VOC of 0.93 V are achieved, resulting in a PCE over 20.5%

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement

Advanced Materials, EarlyView.
The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...
