Scientific breakthroughs into surfaces/interfaces with high overall durability are critical to meet humanity's aspirations for sustainable development. With this context, I seek to undertake fundamental research to nanoengineer new bioinspired liquid-repellent films featuring resistance to sustained high-speed impact, fatigue and continuous flow (shear). My specific objectives are to:1) nanoengineer robust and flexible films with amphiphobicity (i.e. repellence to water and low surface tension liquid) built through thickness2) nanoengineer multi-layered amphiphobic film with mechanical anisotropy and energy dissipative mechanisms for impact/fatigue tolerance3) develop new insights into visco-elasto-plastic failure of the amphiphobic films using electron microscopy integrated nanomechanical tests and exploit them to engineer robust piezocatalytic films 4) perform first high-speed (~350 m/s) liquid/solid particle impact experiments on robust amphiphobic films, demonstrate their anti-icing, anti-scaling and optical transparency potential and to exploit robust piezocatalytic films to introduce continuous flow water remediation for pollution and disease control.The proposed protective nanoengineered films offer a substrate-independent solution for impact/erosion issues that plague transport systems, wind-turbines and offshore installations, and infrastructure exposed to harsh weather. These applications will also benefit from passive anti-icing/scaling potential of our films. With optical transparency, the films may prevent contamination of windows/windshields and handheld devices (e.g. phones/tablets). Furthermore, the piezocatalytic films may be retrofit to industrial/domestic pipes to enable continuous water remediation - this will reduce water waste and the antimicrobial resistance (AMR) burden, and potentially save millions of lives/year. Overall, the fellowship will contribute to sustainable development and meeting the European Green Deal targets.

具有较高整体耐用性的表面/界面的科学突破对于满足人类对可持续发展的愿望至关重要。在这种情况下，我试图对纳米工程师进行基础研究，以抗持续的高速冲击，疲劳和连续流动（剪切）具有抵抗力。我的具体目的是：1）通过厚度构建的纳米工程稳健和灵活的电影（即对水和低表面张力液体的排斥）2）纳米发动机多层次的两亲性薄膜机械性膜和能量耗散机制，以影响/疲劳的能力 - 从 amphiphobic films using electron microscopy integrated nanomechanical tests and exploit them to engineer robust piezocatalytic films 4) perform first high-speed (~350 m/s) liquid/solid particle impact experiments on robust amphiphobic films, demonstrate their anti-icing, anti-scaling and optical transparency potential and to exploit robust piezocatalytic films to introduce continuous flow为污染和疾病控制的水修复。拟议的保护性纳米工程膜提供了与底物无关的撞击/侵蚀问题的解决方案，这些解决方案会困扰着运输系统，风力驾驶器和海上装置以及暴露于恶劣天气的基础设施。这些应用还将受益于我们电影的被动抗冰/缩放潜力。具有光学透明度，这些膜可能会防止窗户/挡风玻璃和手持设备（例如电话/平板电脑）污染。此外，压电膜可以改造为工业/家用管道以实现连续的水补救 - 这将减少水废物和抗菌耐药性（AMR）负担，并有可能挽救数百万的生命/年。总体而言，奖学金将有助于可持续发展并实现欧洲绿色交易目标。
