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. The proposed program is to understand fundamental interaction mechanisms in bio-inspired nanocomposites applicable in wastewater remediation and to explore bio-inspired, green and morphology-controllable bottom-up synthetic pathways to grow nanoparticles in nanocomposites. In the proposed research program, I will: (i) develop techniques at micro- and nano-scale and employ direct nano-scale interaction force probes; (ii) learn from nature and develop biomimetic synthetic pathways and biomimetic nanocomposites. The long-term goal is to design and develop novel materials/technologies applicable in energy and environment, such as oil recovery improvement, wastewater treatment, tailings settling enhancement, emission controls, etc. The near-term goal is to design and develop bio-inspired nanocomposite materials which are expected to be highly efficient, biocompatible, biodegradable and cost-effective for wastewater remediation. The major outcomes will be development of bio-inspired green composite materials with enhanced functionality and improved environmental profiles applicable in energy and environment of Canada, especially the remediation of oil sands process affected water. The highly qualified personnel participating in this program will obtain interdisciplinary skills in materials science/engineering, nanotechnology, water chemistry, etc., also they will obtain academic and industrial knowledge and experience that can strengthen Alberta's and Canada's wastewater treatment management.

工业过程（例如，提取沥青，化石燃料燃烧，矿物质剥削，化学制造等）引起了一些严重的环境问题，例如温室气体排放，废水产生，尾矿积累，污染污染等。新型纳米复合材料非常有害这些问题，这些问题与这些问题非常有用高表面到体积比例纳米级特征，并提供出色的物理和化学特性。大量的研究工作致力于开发适用于废水处理/补救的纳米复合材料。但是，尽管做出了巨大的努力，但在废水处理中的设计和生产仍然是一项重大的科学挑战。纳米级探针对界面特征和相互作用的基本理解将指导废水修复中的材料发展。采用环保方法合成纳米复合材料，最少使用有毒化学物质是另一个科学挑战。大自然提供了一所绿色材料灵感的学校，例如，湍流海中贻贝的粘附和生存能力揭示了多巴胺在小说和绿色纳米复合材料开发中的重要性。 拟议的计划是了解适用于废水补救的生物启发的纳米复合材料中的基本相互作用机制，并探索以生物启发的，绿色和形态控制的自下而上的合成途径，可在纳米复合材料中生长纳米颗粒。在拟议的研究计划中，我将：（i）在微观和纳米级开发技术，并采用直接的纳米级相互作用力探针； （ii）从自然中学习并发展仿生合成途径和仿生纳​​米复合材料。长期目标是设计和开发适用于能源和环境的新型材料/技术，例如改善油，废水处理，尾矿沉降，增强，排放控制等。近期目标是设计和开发生物启发的纳米复合材料，这些材料预计会高效，生物相容性，生物兼容，生物降解，可降解和成本效益。 主要结果将是开发以生物启发的绿色复合材料的开发，其功能性增强并改善了适用于加拿大能源和环境的环境概况，尤其是对油砂过程的修复。参加该计划的高素质人员将获得材料科学/工程，纳米技术，水化学等方面的跨学科技能，他们还将获得可以增强艾伯塔省和加拿大加拿大废水处理管理的学术和工业知识和经验。
