ABSTRACTProposal No. CTS-0318241Principal Investigator: K. Stebe, Johns Hopkins UniversityThis grant is for the acquisition of an Imaging Ellipsometer. By impinging polarized light on a surface and measuring the change in polarization of the reflected beam, ellipsometers determine film thicknesses on solid surfaces with angstrom level resolution. Imaging ellipsometry performs these measurements by focusing the beam onto a high resolution CCD camera to provide spatial resolution of 1micron over areas as large as 400 x 500 microns, allowing for the construction of surface topological maps at that resolution.The measurement of such surface topologies is useful in disciplines ranging from sputter rippling of gold films to the evolution of adsorbed protein films on polymeric surfaces used for controlled drug release. Therefore, this instrumentation will advance research and educational efforts in several research groups at JHU. Undergraduate and graduate students from the departments of Chemical & Biomolecular Engineering will use the imaging ellipsometer and Materials Science & Engineering in projects administered by the co-PIs in the general areas of nanotechnology, surface science and bioengineering. The co-PIs have a record of effective collaboration. Three of the co-PIs have created new courses for an undergraduate concentration between the departments of Chemical & Biomolecular Engineering and Materials Science & Engineering. All of the co-PIs have made a concerted effort at increasing the numbers of women and underrepresented minorities students in their research programs. At the undergraduate level, students are drawn into research via research projects for credit, and via REU programs administered through our MRSEC and in the department of Chemical & Biomolecular Engineering. Through these channels, the co-PIs together have directed 60 undergraduates in research projects, of whom 31 were female and 4 were drawn from other under-represented groups. At the Ph.D and post-graduate levels, women and minorities are also actively recruited. This focus is apparent in the numbers of women and members of under-represented groups being trained in these programs; of the 30 Ph.Ds and postdoctoral researchers, half have been women, and two were drawn from other under-represented groups. The acquisition of this equipment will support the co-PIs efforts in their research and outreach efforts.* Jointly supported by the Major Research Instrumentation (MRI) program and the Interfacial, Transport and Thermodynamics Program

Abstract Propopals No. CTS-0318241原理研究员：K。Stebe，Johns Hopkins University Turnisthis Grant用于收购成像椭圆机。 通过在表面上撞击偏振光并测量反射光束的极化变化，椭圆计确定了具有Angstrom水平分辨率的固体表面上的膜厚度。 Imaging ellipsometry performs these measurements by focusing the beam onto a high resolution CCD camera to provide spatial resolution of 1micron over areas as large as 400 x 500 microns, allowing for the construction of surface topological maps at that resolution.The measurement of such surface topologies is useful in disciplines ranging from sputter rippling of gold films to the evolution of adsorbed protein films on polymeric surfaces used for受控药物释放。因此，这种仪器将在JHU的几个研究小组中提高研究和教育工作。 化学与生物分子工程系的本科生和研究生将在纳米技术，表面科学和生物工程的一般领域管理的项目中使用成像椭圆计和材料科学与工程。 Co-Pis有有效的合作记录。 其中三个共同案例为化学与生物分子工程与材料科学与工程部门之间的本科集中度创建了新课程。 所有的共同案例都齐心协力，以增加其研究计划中妇女和代表性不足的少数群体学生的数量。 在本科生，通过研究项目以及通过MRSEC和化学与生物分子工程系管理的REU计划，将学生吸引到研究项目中。 通过这些渠道，共同提出了研究项目中的60名本科生，其中31名是女性，其中4个来自其他代表性不足的群体。 在博士学位和研究生级别上，妇女和少数民族也被积极招募。 在这些计划中接受过培训的妇女和代表性不足的群体的成员的人数和成员的数量中，这种重点是显而易见的；在30位博士学位和博士后研究人员中，有一半是女性，而另外一个人则来自其他代表性不足的群体。该设备的收购将支持其研究和推广工作中的共同工作。*由主要的研究工具（MRI）计划和界面，运输和热力学计划共同支持
