Advanced Materials Interfaces, EarlyView.Thin SiGe buffer layers are grown by oxidative solid‐phase epitaxy, resulting in a nanopatterning of varying Ge concentration across the surface of the sample. The nanopatterning is caused by a hexagonal network of dislocations on the SiGe/Si(111) interface, and is visible by scanning electron microscopy, providing a non‐destructive method for ...

W-Cr-C-N Nanocomposite Thin-Film Coatings via Reactive Magnetron Sputtering [PDF]
, 2011 While binary tungsten carbide can form smooth, hard films, these suffer from low fracture toughness. Tungsten nitride films are frequently harder, but are more brittle.

Advanced Materials Interfaces, EarlyView.A wrapped copper–vanadium interface enables reliable chemical vapor deposition growth of vanadium carbide micro‐ and nanocrystals. Adjusting methane supply shifts the process from the formation of many small crystals toward lateral expansion and merging of larger domains, while longer growth increases surface coverage without changing the cubic ...

Tungsten fibre reinforced Zr-based bulk metallic glass composites
, 2007 A Zr-based bulk metallic glass (BMG) alloy with the composition (Zr55Al10Ni5Cu30)98.5Si1.5 was used as the base material to form BMG composites. Tungsten fiber reinforced BMG composites were successfully fabricated by pressure metal infiltration ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Advanced Optical Materials, EarlyView.Electric fields drive dynamic photonic assemblies that reversibly generate structural color. By tuning nanoscale organization through controlled particle disorder, the presented system exhibits a unique binary color response, switching between blue and pink depending on viewing angle. Combined with metameric design, this allows for a two‐factor optical
