Advanced Materials Technologies, EarlyView.A biomimetic Jigsaw pattern infill for 3D printer has been developed. Its mechanical features with continuous carbon fiber reinforcement (CCFR) are investigated through the Design of Experiments. The Jigsaw infill minimizes mechanical strength losses caused by variability in infill density, flow rate, or carbon fiber string amount, outperforming ...

Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels
Advanced Materials Technologies, EarlyView.Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View
Advanced Photonics Research, EarlyView.Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.

Advanced Photonics Research, EarlyView.A scalable, low‐cost approach for assembling single germanium nanowires (NWs) into photodetectors is demonstrated using a modified dielectrophoresis method with a voltage‐divider circuit. This self‐limiting assembly technique achieves ultrahigh responsivity (>6 × 105 A W−1) at 700 and 1550 nm without requiring nanoscale electrodes, offering a versatile
