Structure and physical-mechanical properties of nitride and carbide coatings obtained with magnetron sputtering [PDF]
, 2016 It has been found that the vanadium compounds have a coefficient of friction lower than the control samples HSS, the lowest values were determined for the vanadium carbide (μ = 0.5-0.56). The wear mechanism changes from a cohesive wear, in the case of

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids
Advanced Functional Materials, EarlyView.This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
