Evaporating Fluid Microstructures: A Means of Directing Nanoparticle Assembly

摘要-0244592K。在拟议的项目中，将研究在能量不均匀的固体衬底上具有悬浮纳米颗粒的液体薄膜的行为。这项研究分两步进行。第一部分是利用蒸发水膜中在小尺度上占主导地位的界面相互作用来指导新的流体微结构的形成。第二部分是研究纳米粒子在液体层中的分散和在液体表面使用表面活性剂系统蒸发的方法。如果成功，这项研究可能会对包括存储设备、生物传感器和MEMS设备在内的许多应用产生重大影响。

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.
