Quasi‐Periodic Surface Functionalization by Ultra‐Short Pulsed Laser Processing: Unlocking Superior Heat Transfer in Vapor Chambers

Advanced Functional Materials, EarlyView.
Ultra‐short pulsed laser processing (ULSP) enables scalable, open‐air fabrication of self‐organized, quasi‐periodic micro/nanostructures on copper using 100 µm laser beams, orders of magnitude larger than the resulting surface features. Integrated into ultra‐thin, wick‐free vapor chambers, these laser‐functionalized surfaces dramatically enhance ...

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

Advanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Enhancing the Photocatalytic Performance of Carbon Nitrides Through Controlled Local Structure Modification

Advanced Functional Materials, EarlyView.
This work utilizes poly(heptazine imides) as a model system to demonstrate how fine‐tuning the crystal structure influences the photocatalytic properties of layered carbon nitrides in the hydrogen evolution reaction. In particular, the nature of rotational defects and the hydration shell of cations are key contributors to enhanced hydrogen evolution ...
