Self‐Assembled hBN Wrinkles as Planar Optofluidic Channels

Small, EarlyView.
Thermally induced wrinkling creates nanochannel networks in hexagonal boron nitride flakes without lithography. Channel dimensions depend on flake thickness and substrate. Liquid infiltration into the networks and fluorescence localization of DNA along the channels highlight their potential as a scalable, optically addressable planar nanofluidic ...

Chain Orientation and Polycrystalline Disorder as Antagonistic Descriptors of Thermal and Triboelectric Transport in 3D‐Nanoconfined PMMA, PEEK, and PET Nanowire Networks

Small, EarlyView.
Nanoconfinement in interconnected 3D‐AAO provides a common platform to disentangle crystallinity, crystalline texture, and microstructural disorder in PMMA, PEEK, and PET. Amorphous PMMA exhibits a 350% thermal conductivity increase, demonstrating a substantial confinement‐related contribution independent of crystallization, while strongly oriented PET

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...
