Atomic Step–Terrace Ordering Enables Unprecedentedly Low Pop‐in Stress Scatter in GaN (0001)

Small, EarlyView.
Step–terrace GaN surfaces with monoatomic topography were realized using catalyst‐referred etching. On these surfaces, pop‐ins occurred at ideal strength with a record‐low stress scatter of 2.3%, providing compelling evidence that atomic‐scale surface ordering plays a critical role in triggering incipient plasticity. Atomic‐scale surface irregularities,

Shear‐Induced Anisotropic Supramolecular Gel Noodles for Improved Cell Guidance in Polarized Tissue Engineering

Small, EarlyView.
A simple two‐stage extrusion aligns supramolecular fibrils into 1D gel noodles. The residual pressure in the viscous pre‐gel drives the formation of a thin filament that is locked by Ca2+ cross‐linker into a highly anisotropic segment. The aligned noodles show enhanced tensile strength and guide myoblast elongation along the fiber, mimicking aligned ...

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1

Small, EarlyView.
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

Zincophilic Porous Carbon Interface with Dendrite‐Free Zinc Deposition via Selective Ion Regulation for Aqueous Zinc Ion Batteries

Small, EarlyView.
A multifunctional zincophilic porous carbon (ZPC) layer is engineered as a protective layer for aqueous zinc‐ion batteries (AZIBs). The ZPC layer guides Zn2+ diffusion and desolvation through ion adsorption sites. Also, its polar functional groups enhance interfacial adhesion and redox activity.

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.
