PI: James F GilchristProposal Number: 1120399This research seeks to advance the fundamental manufacturing science of nanoparticle monolayer self-assembly and deposition as a unit operation for commercial nano manufacturing. Specifically, the proposed project will investigate the fundamental aspects of self-assembly methods, incorporate these discoveries into continuous roll-to-roll commercial-scale processes, and develop novel applications that utilize these processes. These processes will enable production of nanoporous membranes, flexible dye sensitized solar cells (DSSCs), and light emitting diodes (LEDs).Intellectual MeritThis scalable nanomanufacturing program focuses on development of two separate but fundamentally related continuous processes that deposit self-assembled particle arrays on substrates. The first process focuses on convective deposition, and the second process focuses an automated Langmuir-Blodgett deposition. Both processes utilize capillary interactions of particles confined in thin films for directed particle self-assembly. Experimental and computational methods for exploring the fundamental mechanisms, limitations, and stabilities of each of these processes will advance rational scale-up and continuous operation and determination of new deposition control parameters. This fundamental insight will serve as the foundation for identifying expanded uses and target applications. To ensure feasibility and robustness of these processes, three energy and bioengineering-related applications will be developed in tandem utilizing self-assembled particle depositions derived from these processes. These include development of nanostructured dye supports in dye sensitized solar cells (DSSCs), coatings and internal structures for light emitting diodes (LEDs), and large-are periodic nanoporous membranes for molecular to viral separations. Broader impacts Development of broadly applicable, commercial particle monolayer deposition processes could have far-reaching impact on a multitude of industrial applications. Fundamental research on colloidal self-assembly via capillary interactions and concomitant research into fundamental scientific aspects and scalable production of nanoporous membranes, DSSCs, and LEDs could also impact a wide variety of scientific disciplines and industries, and could lead to significant advancements in key areas of disease detection and energy applications. Direct collaboration with industrial partners, including Versatilis, LLC and PAower Optics LLC will guide efforts to commercialization. Undergraduate and graduate students will be trained in the principles of scale-up, surface science, particle technology, self-assembly, photovoltaics, separations, and a multitude of characterization techniques. A primary student initiative in collaboration with members of the Lehigh College of Education will expose K-5 students to topics related to fundamental surface science and scientific methods.

项目负责人：James F gilchrist提案号：1120399本研究旨在推进纳米粒子单层自组装和沉积的基础制造科学，作为商业纳米制造的单元操作。具体来说，拟议的项目将研究自组装方法的基本方面，将这些发现纳入连续的卷对卷商业规模流程，并开发利用这些流程的新应用。这些工艺将使纳米多孔膜、柔性染料敏化太阳能电池（DSSCs）和发光二极管（led）的生产成为可能。这个可扩展的纳米制造项目专注于开发两个独立但基本相关的连续工艺，将自组装的粒子阵列沉积在基板上。第一个过程侧重于对流沉积，第二个过程侧重于自动Langmuir-Blodgett沉积。这两种方法都利用薄膜中粒子的毛细管相互作用进行定向粒子自组装。探索这些过程的基本机制、局限性和稳定性的实验和计算方法将促进合理的放大和连续操作，并确定新的沉积控制参数。这一基本见解将作为确定扩展用途和目标应用程序的基础。为了确保这些工艺的可行性和稳健性，三种与能源和生物工程相关的应用将利用这些工艺产生的自组装颗粒沉积进行串联开发。其中包括染料敏化太阳能电池（DSSCs）中纳米结构染料载体的开发，发光二极管（led）的涂层和内部结构的开发，以及用于分子与病毒分离的大周期纳米孔膜的开发。广泛适用的商业颗粒单层沉积工艺的发展可能对众多工业应用产生深远的影响。通过毛细管相互作用进行胶体自组装的基础研究，以及对纳米孔膜、DSSCs和led的基础科学方面和可扩展生产的相关研究，也可能影响各种科学学科和行业，并可能在疾病检测和能源应用的关键领域取得重大进展。与工业合作伙伴（包括versatile， LLC和papower Optics LLC）的直接合作将指导商业化工作。本科生和研究生将接受放大、表面科学、粒子技术、自组装、光伏、分离和众多表征技术原理的培训。与利哈伊教育学院成员合作的一项小学生倡议将使K-5学生接触与基础表面科学和科学方法相关的主题。
