Abstract Bio-inspired macrostructure array (MAA, size: submillimeter to millimeter scale) materials with special wettability (MAAMs-SW) have attracted significant research attention due their outstanding performance in many applications, including oil repellency, liquid/droplet manipulation, anti-icing, heat transfer, water collection, and oil–water separation. In this review, we focus on recent developments the theory, design, fabrication, application of bio-inspired MAAMs-SW. We first review history basic theory discuss representative structures corresponding functions some biological surfaces, thus setting stage for design fabrication then summarize methods wetting MAAs terms three categories: additive manufacturing, subtractive formative as well diverse functional providing insights into development these Finally, challenges directions future MAAMs-SW are briefly addressed. Worldwide efforts, progress, breakthroughs from surface engineering applications elaborated herein will promote practical

Scarfing is a type of flame treatment used to improve the quality metal generated during steelmaking. It employs principles gas cutting remove impurities and defects. Due high-temperature conditions need for uniform treatment, mechanical scarfing performed via frame preferred over manual hand scarfing. To achieve stable scarfing, properly designed essential. Generally, while using more material can create equipment, it also increases costs. Therefore, this study proposed design method that selects an acceleration profile minimize shock on equipment operation multi-objective genetic algorithm weight maximize rigidity. Because modifying existing based optimization results would incur additional costs time, pre-optimizing through simulation before fabrication crucial. Optimization was achieved dimensional equipment. As result, each part deformation decreased by average 17.05 kg 3.93%, respectively.

Abstract High-bandwidth nano-positioning stages (NPSs) have boosted the advancement of modern ultra-precise, ultra-fast measurement and manufacturing technologies owing to their fast dynamic response, high stiffness nanoscale resolution. However, nonlinear actuation, lightly damped resonance multi-axis cross-coupling effect bring significant challenges design, modeling control high-bandwidth NPSs. Consequently, numerous advanced works been reported over past decades address these challenges. Here, this article provides a comprehensive review NPSs, which covers four representative aspects including mechanical system modeling, parameters optimization motion control. Besides, NPSs applied atomic force microscope tool servo are highlighted. By providing an extensive overview design procedure for aims offer systemic solution achieving operation with speed, accuracy Furthermore, remaining difficulties along future developments in fields concluded discussed.

Small-sized ultra-precise optical devices require compact compliant ortho-planar springs (COPS) aka. flexure springs, for precise, frictionless linear motion which depends highly on the design. A self-developed arm-hinge-linked design, named "Panto-style" spring was optimized by selecting 5 design parameters (thickness: t, hinge width: W, arm length 1 and 2: L1 L2, angle: Ө) constructing sets of experiments (DOEs).Signal-to-noise ratio (SNR) response surface model (RSM) regression were obtained in terms axial deformation. The highest from main effects plot thickness, followed width, W. angle arm, Ө, considered a non-relevant parameter.The optimization implemented with constraint input output. Kinetostatic performances (axial/radial deformations, stress) predicted, validated, compared (RSM, KNN, FE simulations, experiments) using design.The average value KNN RSM (KNN + RSM) increased accuracy deformation to alone. To conclude, parameter has successfully predicted output results confirmed both numerically experimentally.
