ABSTRACTCTS-0002150Cerro, R./ U. of AlabamaHighly ordered organic films, one molecule in thickness, continue to be one of the fastest growing areas of applied nano-science. A few important areas of applications for nano-technology include nano-biosensors, nano-chemical sensors, nonlinear optic devices, and bio-resistant/bio-compatible protective coatings. The oldest method for manufacturing ultra-thin organized chemical layers is the Langmuir-Blodgett technique.The Langmuir-Blodgett technique, however, ahs not been used on an industrial scale for the manufacturing of nano-technology devices due to the apparent inability to control the hydrodynamic variable needed for reliable thin film deposition. Most of the problems associated with the Langmuir-Blogett techniques for thin film deposition can be traced back to the complex dynamics of the gas-liquid -solid moving contact line. We discuss in this proposal how recent experimental and theoretical advances on the dynamics of moving contact lines can be used to develop a fundamental knowledge can be used in turn to provide a physical model of the deposition process that will pave the way for developing faster industrial- scale methods to manufacture ordered thin films.The development of faster, cheaper and reliable L-B deposition processors will impact some of the most active areas in nano-technology, such as the manufacture of MEMS, and the development of extremely sensitive chemical-detecting or bio-detecting devices.This proposal is submitted in similar versions to the NSF by the university of Alabama in Huntsville and to UK's Engineering and Physical Sciences Research Council (EPSRC) by Leeds University. The main strength of this proposal is to collaborative team approach that will be used to analyze the experimental and theoretical aspects of this research and on the collective expertise brought into the proposal by the groups at the USA and UK.

Abstractcts-0002150Cerro，R。/ U./ U. of Alabamahighly有机膜，一个厚度的分子，仍然是应用纳米科学中生长最快的地区之一。 纳米技术应用的一些重要领域包括纳米生物传感器，纳米化学传感器，非线性光学设备以及耐生物学/生物兼容的保护涂层。 制造超薄有组织的化学层的最古老方法是Langmuir-blodgett技术。但是，Langmuir-Blodgett技术未在工业规模上用于纳米技术设备的制造，因为显然无法控制可靠的流体动力型薄膜薄膜的可靠性薄膜层。 与薄膜沉积的Langmuir-Blogett技术相关的大多数问题都可以追溯到气液 - 固体移动接触线的复杂动力学。 我们在这项建议中讨论如何使用移动接触线动态的最新实验和理论进步来开发基本知识，依次使用沉积过程的物理模型，为开发更快的工业规模方法铺平道路，以制造有序的薄膜。该提案的开发是由阿拉巴马大学在亨茨维尔的NSF和英国的工程与物理科学研究委员会（EPSRC）的开发。 该提案的主要优势是合作团队方法，该方法将用于分析这项研究的实验和理论方面以及美国和英国小组提出的集体专业知识。
