What happens when 32 labs join forces to study nanoparticle‐modified powders? A data‐driven journey through laser powder bed fusion—now openly accessible for the entire additive manufacturing community—is studied. Laser powder bed fusion is a cornerstone technology for additive manufacturing (AM) of metals and polymers, yet challenges in achieving ...

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12
Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

Active Thermal Field Integration for Marangoni‐Driven Salt Rejection and Water Collection
A thermal gradient fabric (TGF) evaporator with an auxiliary active thermal field can simultaneously increase evaporation rates and achieve long‐term salt rejection. The auxiliary active thermal field is well integrated with solar energy to construct moderate, extensive, and circulating Marangoni flow for salt rejection.

Numerical study on signatures of atmospheric convective cells in radar images of the ocean
Current and wind variations at the ocean surface can give rise to a modulation of the sea surface roughness and thus become visible in radar images. The discrimination between radar signatures of oceanic and atmospheric phenomena can be quite difficult ...

The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...

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 ...
