Evaporating Fluid Microstructures: A Means of Directing Nanoparticle Assembly

摘要CTS-0244592 K。Stebe，约翰霍普金斯大学在拟议的项目中，将研究具有悬浮纳米颗粒的液体薄膜在能量不均匀的固体基底上的行为。 研究分两步进行。 第一部分是利用在小尺度上占主导地位的界面相互作用，在蒸发水膜中直接形成新的流体微结构。 第二部分是研究通过在液体层中分散纳米颗粒和在液体表面使用表面活性剂系统蒸发来在表面上沉积纳米颗粒的方法。 如果成功，这项研究可能会对许多应用产生重大影响，包括存储设备，生物传感器和MEMS设备。

ABSTRACTCTS-0244592K. Stebe, Johns Hopkins UniversityThe behavior of thin liquid films, with suspended nanoparticles, on energetically non-uniform solid substrates will be investigated in the proposed project. The research is proposed in two steps. The first part is to harness interfacial interactions, which dominate at small scales, in evaporating water films to direct the formation of new fluid microstructures. The second part is to study methods for depositing nanoparticles on surfaces by dispersion of nanoparticles in the liquid layer and systematic evaporation using surfactants in the liquid surface. If successful, this research could have significant impact on many applications including storage devices, biosensors, and MEMS devices.
