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

open access: yesAdvanced 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 ...

Highly Active Air Electrode with Enhanced Proton Conduction via Isovalent Doping in a Layered Perovskite for Reversible Protonic Ceramic Cells

open access: yesAdvanced Functional Materials, EarlyView.
A Ni‐doped PBSCN20 air electrode is proposed as a promising air electrode material for reversible protonic ceramic cells. An isovalent doping significantly facilitates oxygen vacancy formation and proton uptake while simultaneously reducing the energy barrier for proton migration.

Additively Manufactured Diamond for Energy Scavenging and Wireless Power Transfer in Implantable Devices

open access: yesAdvanced Functional Materials, EarlyView.
Additive manufacturing is expanding beyond mechanical prosthetics into microelectronic implants. This work presents a diamond‐titanium hybrid that enables wireless power transfer, localized heating, and flow sensing. The use of additive manufacturing combined with the biocompatibility of the diamond‐titanium hybrid material paves the way toward new ...

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

open access: yesAdvanced 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 ...
