This grant supports purchase of a phase-modulated spectroscopic "Picometer" ellipsometer from Beaglehole Instruments. With response times on the order of 1 millisecond and adsorbed mass sensitivity on the order of 2 ng/cm 2, this high-speed, high-sensitivity instrument will be used to study in real-time the assembly and organization of soft materials at interfaces over both short and long time scales. This instrument will also be used to monitor adsorption events at polymer-modified interfaces. A set of projects that will benefit immediately from the capabilities of this instrument include the analysis of the assembly of polymer amphiphiles, the growth of surface-confined polymers, the dynamics of redox molecules at electrodes, and the morphology of thin films of optoelectronic polymers. The spectroscopic ellipsometer will be housed in the recently created Surface Characterization Laboratory, located in the Chemical Engineering Department. Post-doctoral researchers and graduate and undergraduate students from several disciplines (the Chemical Engineering, Bioengineering, and Environmental Engineering and Science Departments) currently utilize this multi-user facility. The scientific projects underway impact important areas, such as advancing the technology for molecular electronics and optoelectronic polymer devices, creating (bio) separation agents designed at the nanoscale, and tailoring interfacial layers that can screen antigenic displays on cells. These research projects will enable expansion of the diversity of students working in the Surface Characterization Laboratory to include students from Chemistry and Materials Science & Engineering, thus providing a truly interdisciplinary training environment. The Picometer and associated facility will be available to faculty and students from nearby non-Ph.D. granting colleges that have an association with Clemson's Chemical Engineering Department through the Research Exploration programs. The Picometer will also help to grow the Surface Characterization Laboratory into a state-of-the-art facility in the area of advanced materials research, a core research theme at Clemson University.

这笔赠款支持购买一个相位调制光谱“皮米”椭圆偏振仪从Beaglehole仪器。响应时间为1毫秒的顺序和吸附质量的灵敏度为2纳克/厘米2的顺序，这种高速，高灵敏度的仪器将被用来研究在实时的组装和组织的软材料在界面在短期和长期的时间尺度。该仪器还将用于监测聚合物改性界面处的吸附事件。一系列项目将立即受益于该仪器的功能，包括聚合物两亲物的组装分析，表面限制聚合物的生长，电极上氧化还原分子的动力学，以及光电聚合物薄膜的形态。光谱椭偏仪将被安置在最近创建的表面表征实验室，位于化学工程系。博士后研究人员和研究生和本科生从几个学科（化学工程，生物工程，环境工程和科学部门）目前利用这个多用户设施。正在进行的科学项目影响着重要的领域，例如推进分子电子学和光电聚合物器件的技术，创造纳米级设计的（生物）分离剂，以及定制可以筛选细胞上抗原展示的界面层。这些研究项目将扩大在表面表征实验室工作的学生的多样性，包括化学和材料科学工程的学生，从而提供一个真正的跨学科培训环境。Picometer和相关设施将提供给附近非博士的教师和学生。通过研究探索计划授予与克莱姆森化学工程系有联系的学院。Picometer还将帮助表面表征实验室发展成为先进材料研究领域的最先进设施，这是克莱姆森大学的核心研究主题。
