Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

Small, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...

Polypyrrole Nanofibrous Aerogel for Pressure Sensing and Anionic Contaminant Remediation

Small, EarlyView.
Nanofibrous aerogels (NFAs), highly porous ultralow‐density networks of entangled nanofibers, are conformally coated with polypyrrole (PPy) to provide a multifaceted material platform. Leveraging NFA's high surface area and mechanically robust structure with the conductive properties of PPy enables pressure‐responsive sensing for flexible electronics ...

Engineering Janus Nanofiber Interfaces for Simultaneous Triboelectric Enhancement and Wearable Comfort

Small Methods, EarlyView.
A moisture‐wicking Janus bilayer triboelectric nanogenerator (MW‐JBT) that integrates directional moisture transport with dielectric‐engineered electrospun nanofibers was developed. When incorporated into a plantar sensing system and combined with a deep learning algorithm, the MW‐JBT achieved a fall‐detection accuracy of 88.5%. This study demonstrates

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61
