Spills and leakage of oil during offshore oil production or marine transportation cause both long-term damage to water ecosystems and loss of valuable resources. Thus, efficient strategies for capturing and treating such releases are urgently required. Gravity-driven siphons allow the transport of liquids between phases. Siphons have been utilized for various applications and hold promise for oil recovery. However, siphon devices generally suffer from significant issues such as low oil removal flow rate, poor stability, and inability to self-restart after disruption of the siphon. The goal of this project is to develop a novel oil skimming technology based on a new chemically modified graphene material. The hydrophobic nature of graphene is expected to result in high remediation efficiency. Experiments guided by computational molecular simulations will provide fundamental understanding of the interaction of oil with graphene nanochannels. Successful completion of this research will help guide the design of spontaneous, self-powered, and continuous oil remediation systems with significantly enhanced efficiency. Such systems would have broad-reaching impact on society by alleviating environmental and human health impacts of spilled oil. The overall goal of this research project is to understand the nature of interaction between oil and graphene nanochannels. This will be achieved through experiments designed to elucidate the mechanisms governing the synergistic effects of the nanochannel geometry and surface functionalization of plasma-nanoengineered, vertically standing graphene petal (GP) oil skimmers. Guided by molecular simulation results, researchers will design and demonstrate an oil skimmer system based on chemically modified GPs with controlled morphologies for spontaneous, self-powered, and highly efficient oil spill remediation. The knowledge learned from this research will offer insights into developing unique graphene materials to address pressing oil pollution issues. The design principles will also accelerate broader applications of graphene materials to other environmental applications such as seawater desalination, wastewater treatment, and soil and air pollution prevention and remediation. The project will also include significant educational activities, including research programs for local K-12 students, teachers, and undergraduates. Society will benefit from students acquiring relevant knowledge and skills to diversify and train the STEM workforce of the future.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在海上石油生产或海洋运输过程中，石油的溢出和泄漏既会对水生态系统造成长期损害，又损失了宝贵的资源。因此，迫切需要捕获和治疗此类释放的有效策略。重力驱动的虹吸管允许在相之间运输液体。虹吸管已被用于各种应用，并保持回油的承诺。但是，虹吸器件通常会遇到重大问题，例如低油流量，稳定性较差以及虹吸管中断后无法自我首先。该项目的目的是基于新的化学改装石墨烯材料开发一种新型的油脂技术。石墨烯的疏水性有望导致高补救效率。以计算分子模拟为指导的实验将提供对石油与石墨烯纳米通道相互作用的基本理解。这项研究的成功完成将有助于指导自发，自动和连续的石油补救系统的设计，其效率显着提高。这样的系统将通过减轻溢出的石油的环境和人类健康影响对社会产生广泛的影响。该研究项目的总体目标是了解石油和石墨烯纳米通道之间相互作用的性质。这将通过旨在阐明纳米渠道几何形状和等离子 - 纳米工程的表面功能的机制来实现，从而实现这一目标。在分子模拟结果的指导下，研究人员将设计并证明基于化学修饰的GP的油撇油系统，具有控制形态，用于自发，自动且高效的漏油器修复。从这项研究中学到的知识将提供有关开发独特的石墨烯材料来解决压迫石油污染问题的见解。该设计原理还将加速石墨烯材料在其他环境应用中的广泛应用，例如海水脱盐，废水处理以及土壤和空气污染预防和补救。该项目还将包括重要的教育活动，包括针对本地K-12学生，教师和本科生的研究计划。社会将受益于获得相关知识和技能的学生，以多样化和培训未来的STEM劳动力。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准通过评估来获得支持的。
