项目摘要

Industrial processes (e.g., bitumen extraction, fossil fuel combustion, mineral exploitation, chemical manufacturing, etc.) have caused some serious environmental issues, e.g., greenhouse gas emissions, wastewater generating, tailings accumulation, soil contamination, etc. Emerging novel nanocomposite materials are very promising for resolving these problems, which combine inorganic and/or organic compounds incorporated with high-surface-to-volume-ratio nanoscale features, and provide remarkable physical and chemical properties. Significant research efforts have been devoted to the development of nanocomposites applicable in wastewater treatment/remediation. However, despite great efforts, the design and producing of cost-effective nanocomposites in wastewater treatment still remains a major scientific challenge. A basic understanding of interfacial characteristics and interaction forces by nano-scale probes will guide the material development in wastewater remediation. Using eco-friendly approaches to synthesize nanocomposites with minimal use of toxic chemicals is another scientific challenge. Nature provides a school for green material inspiration, e.g., the adhesion and survival capability of mussels in turbulent sea unveils the importance of dopamine in novel and green nanocomposite materials development.

工业过程（例如，沥青提取、化石燃料燃烧、矿物开采、化学制造等）造成了一些严重的环境问题，例如，温室气体排放、废水产生、尾矿堆积、土壤污染等。新兴的新型纳米复合材料对于解决这些问题非常有希望，其将结合有高表面体积比纳米级特征的联合收割机无机和/或有机化合物结合，并提供显著的物理和化学性质。大量的研究工作致力于开发适用于废水处理/修复的纳米复合材料。然而，尽管付出了巨大的努力，设计和生产具有成本效益的纳米复合材料在废水处理仍然是一个重大的科学挑战。通过纳米尺度探针对界面特性和相互作用力的基本理解将指导废水修复材料的开发。使用生态友好的方法合成纳米复合材料，最大限度地使用有毒化学品是另一个科学挑战。大自然为绿色材料的灵感提供了一所学校，例如，贻贝在湍流海洋中的粘附和生存能力揭示了多巴胺在新型和绿色纳米复合材料开发中的重要性。
