This proposal seeks to elucidate the behavior of self-propelled Janus particles near interfaces, using molecular dynamics to examine the countervailing influences of Brownian motion, solute concentration gradient, motion-induced fluid flow, and asymmetric force fields. The PI?s divide the main responsibilities according to their experimental and theoretical affiliations, but there are also collaborations with other laboratories in other universities for other techniques (e.g. using colloidal probe atomic force microscopy). The research plan bridges the gap between atomic-level simulations and colloidal-scale modeling and is very innovative and challenging. The results of such an investigation should have broad applications in mixing, assembling, and transport of particles in complex fluids and microfluidic devices.The broader impacts on potential development of active materials in the formulation and directed self-assembly of designer materials, and the use of self-propelled particles in lab-on-a-chip type devices for cargo and drug delivery are very good as is the potential impact of their outreach to underrepresented college-level students.

该建议旨在阐明自推进Janus粒子界面附近的行为，使用分子动力学来研究布朗运动，溶质浓度梯度，运动诱导的流体流动和不对称力场的抵消影响。私家侦探？实验室根据实验和理论关系划分主要职责，但也与其他大学的其他实验室合作进行其他技术（例如使用胶体探针原子力显微镜）。该研究计划弥合了原子级模拟和胶体级建模之间的差距，非常具有创新性和挑战性。这种研究的结果应该在复杂流体和微流体装置中的颗粒的混合、组装和运输中具有广泛的应用。对活性材料在设计材料的配制和定向自组装中的潜在发展的更广泛的影响，以及在实验室中使用自推进粒子用于货物和药物运送的芯片型装置非常好，其推广到代表性不足的大学生的潜在影响也是如此。
