Circularly polarized light (CPL) detection is important in the field of advanced optoelectronics. Traditionally, CPL with optical elements limited by challenge integration. Chiral materials have been investigated for direct without complex elements. However, chiral structures such as absorption layer need further investigation owing to low anisotropy factor (gph). Herein, we demonstrate a composite structure combining cellulose nanocrystals (CNCs) and TiO2 nanotube arrays (TNAs) detection....
The solidification and tensile deformation behaviors of rheo-cast AZ91-Sn alloys were revealed to study the effects Sn alloying on improvement AZ91 alloy’s mechanical properties. Two kinds Mg17Al12 phases precipitated from supersaturated magnesium matrix during rheo-solidification observed: coarse discontinuous precipitates (DP) at grain boundaries small-sized continuous (CP) inside grains. With increasing content, amount was increased whilst Al atoms in decreased. Due higher melting point...
摘要: 随着航空、风电、重载车辆等装备对齿轮传动功率密度、承载能力、疲劳寿命要求的提高,以微点蚀、点蚀、深层齿面断裂等多种形式存在的齿轮接触疲劳失效成为限制现代齿轮及装备服役性能与可靠性的重要瓶颈。通过调研国内外相关研究现状,描述了齿轮接触疲劳失效模式,归纳了现有齿轮接触疲劳理论与寿命预测方法,介绍了连续损伤理论、微结构力学理论在齿轮接触疲劳研究中的作用,辨识了影响齿轮接触疲劳性能的轮齿界面状态、硬化层与残余应力、材料缺陷等结构-工况-材料要素体系,强调了齿面时变滑滚下宏微观形貌-润滑耦合热弹塑接触机理、粗糙齿面疲劳-棘轮-磨损多源损伤机理、多尺度齿轮材料损伤与性能退化、齿轮抗疲劳制造中的表面完整性及其演化机理等科学问题,总结了超精加工、涂层、喷丸等对提高齿轮接触疲劳性能的影响,为进一步理解齿轮接触疲劳失效机理、形成高性能齿轮抗疲劳设计制造方法提供了参考。
Al–0.12Sc–0.04Zr (mass%) alloy conductive wires were designed and produced by continuous rheo-extrusion process. The effects of cold drawing process on microstructure, mechanical properties the after aging treatment at different temperature studied. Results showed that process, secondary Al3(Sc–Zr) phase homogeneously precipitated became smaller in size. tensile strength increased from 115 MPa to 217 due homogeneous distribution Cold did not result severe loss property.
Abstract The medium‐thick plate is an important type of steel product widely used in construction and engineering machinery. orders are usually characterised by multiple specifications small quantities. design part the production process plate, which includes combination sub‐plates size motherboard. A multi‐objective model for proposed based on 2D bin packing model, comprehensively considering spatial constraints production. two‐stage genetic algorithm (TSGA) developed to solve model. In...
Circularly polarized light (CPL) detection and polarization state recognition are required for a wide range of applications. Conventional with optical components causes difficulties miniaturization integration. An effective design strategy is proposed direct CPL chiral material. Here, we realized based on the combination photonic cellulose nanocrystal (CNC) ultraviolet-sensitive ZnO photoconductive The CNC layer deposited by evaporation-induced self-assembly established left-handed nematic...
Polycrystalline Diamond Compact (PDC) bit has been widely used in natural gas/oil drilling industry for its advantages such as no rotating parts, highly rate of penetration (ROP) and durability. In recent decades, the comprehensive property PDC improved rapidly due to scientists’ efforts. Hydraulic design is very important because retention cuttings may dramatically decrease ROP. Most current researches focus on how blade profile nozzle parameters affect hydraulic performance bit, but,...
The steel-concrete double composite girder in the negative flexural region combines an additional concrete slab to steel bottom flange prevent local buckling, however, may lower down neutral axis of section, which is a sensitive factor tensile stress restraint on deck. This actually great importance structural rationality and durability, but has not been investigated detail yet. In this case, series 5.5 m-long specimens were tested by bending, among configuration longitudinal reinforcement...
