Nanopatterned Dual‐Carbon‐Dot Photonic Films With Enhanced Light Outcoupling

Advanced Optical Materials, EarlyView.
Nanoimprinted dual‐carbon‐dot/PVA films combine composition‐tunable blue–green emission with grating‐mediated directional light outcoupling. Water‐processable B‐CD and G‐CD composites are patterned by drying‐assisted nanoimprinting, producing angle‐selective emission peaks that follow the first‐order diffraction condition and exhibit reference ...

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming

Advanced Science, EarlyView.
This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...
