With the support of the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry, Professor T. Randall Lee from the University of Houston will undertake fundamental materials discovery studies based on novel synthetic strategies and materials characterization while evaluating the utility and performance of the resulting materials for use in a variety of technologies that require robust surfaces. These include approaches to anti-fouling coatings for biomedical implants, oil pipelines and marine-based structures, and nanoscale coatings for patterning and protecting electrodes and superconducting tapes, and advanced coatings for controlling wettability and preventing corrosion at the macroscale. Research activities will be closely integrated with educational and outreach efforts. Graduate students, undergraduate students, and high school students will work collaboratively on the projects to gain the training and expertise in areas relevant to emerging technological challenges facing the nation. Recruitment geared toward broadening the participation of women and underserved minorities will include hosting hands-on laboratory activities for students from local high schools having significant underserved minority populations through the University of Houston's teachHouston program. High school students with an interest in research from across the state will have the opportunity to engage in a summer research experience through the Welch Foundation Summer Scholars program.This research program will focus on four central thrusts: (1) the study of multi-dentate adsorbates possessing phase-incompatible or structurally dissimilar chemical compositions for generating stable films having homogeneously mixed "conflicted" compositions as potential nanoscale anti-fouling coatings; (2) the examination of multidentate thiol-based adsorbates that resist desorption as cyclic disulfides for functionalizing the planar faces of 2D transition metal dichalcogenides such as MoS2 to facilitate exfoliation and enable layer-by-layer fabrication of unique hybrid nanostructures for optical and electronic devices; (3) the development of selectively fluorinated adsorbates for generating nanoscale coatings having well-controlled compositions and conformations that permit studies of surfaces dipoles and their historically controversial impacts on interfacial properties; and (4) the custom design and study of adsorbates for generating thin-film interfaces that mimic polymer interfaces, but cannot undergo traditional surface reconstruction. All of this research may be regarded as use-inspired fundamental research on the molecular-level design, development and study of functional surface coatings.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在化学系大分子、超分子和纳米化学项目的支持下，T。来自休斯顿大学的Randall Lee将根据新的合成策略和材料表征进行基础材料发现研究，同时评估所产生材料的实用性和性能，以用于需要坚固表面的各种技术。 这些包括用于生物医学植入物、石油管道和海洋结构的防污涂层，用于图案化和保护电极和超导带的纳米级涂层，以及用于控制润湿性和防止宏观腐蚀的先进涂层。 研究活动将与教育和外联工作密切结合。 研究生，本科生和高中生将在项目上合作，以获得与国家面临的新兴技术挑战相关的领域的培训和专业知识。 面向扩大妇女和服务不足的少数民族的参与的招聘将包括通过休斯顿大学的teachHouston计划为当地高中的学生举办实践实验室活动，这些高中的学生有显著的服务不足的少数民族人口。 来自全州对研究感兴趣的高中生将有机会通过韦尔奇基金会夏季学者计划参与夏季研究体验。该研究计划将侧重于四个中心目标：（1）研究具有相不相容或结构不同的化学组成的多齿吸附物，用于产生具有均匀混合的“冲突”的稳定膜，（2）检查抗解吸为环状二硫化物的多齿硫醇基吸附物，用于官能化2D过渡金属二硫属化物如MoS 2的平面，以促进剥离并能够逐层制造用于光学和电子器件的独特混合纳米结构;（3）开发选择性氟化的吸附物，用于产生具有良好控制的组成和构象的纳米级涂层，这允许研究表面偶极子及其对界面性质的历史上有争议的影响;和（4）定制设计和研究吸附物，用于产生模拟聚合物界面但不能进行传统表面重建的薄膜界面。 所有这些研究都可以被视为在分子水平上设计、开发和研究功能性表面涂层的使用启发基础研究。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
