With this award from the Major Research Instrumentation program the Materials Research Science & Engineering Center (MRSEC) at the University of Pennsylvania (Penn) will establish a shared experimental facility (SEF) to perform electrical, magnetic, thermal and optical measurements for interdisciplinary research and education. The facility will house a new Quantum Design Physical Property Measurement System (PPMS) along with an existing PPMS for which unique magneto-optical capabilities have already been developed. The SEF will house these instruments in a single laboratory accessible to students and post-docs 24 hours a day. The goal is to establish a community of diverse users who will exchange ideas and expertise while working in close proximity.The proposed SEF will be much more than the sum of its parts and will significantly leverage existing resources. The PPMS systems can share experimental inserts by virtue of their modular design, so the newly acquired system will not only add new state-of-the-art capabilities for thermal transport and heat capacity, but will also 'inherit' the high-resistivity, Kerr effect, magnetization, fiber probe, rotating insert, custom software, and operator experience that accompanies the existing system. The second PPMS in the SEF will reduce the backlog of users by allowing any combination of experiments to run simultaneously, and will provide valuable instrument time for building and testing specialized home-built inserts for custom measurements. The intellectual merit of the proposed SEF lies in its role as a potent catalyst for nucleating new interdisciplinary research, especially in material discovery. Since its arrival three years ago, the existing PPMS has already stimulated collaborative activities among researchers with a wide variety of interests. Vigorous and unexpected programs in metallo-DNA, medical physics, carbon nanotubes and nanofibers, magnetoresistive oxides, and conducting organics have been established, most of which originated from exploratory measurements using this instrument. These efforts now require more instrument time than is currently possible, and the new materials have further created new demand for additional capabilities not available at Penn. The proposed SEF will significantly expand MRSEC capabilities and create opportunities in exploratory effort in artificial multifunctional oxide thin films and novel molecular conducting, semi-conducting and spintronic devices, as well as in other unforeseen activities.The broader impact of the proposed SEF lies in the services and opportunities it offers to the science community of Philadelphia and beyond. The SEF instruments are designed for ease of use and continuous operation, and will attract users who might otherwise hesitate, or be denied for lack of experience, to begin a complex measurement. The SEF will avail itself to undergraduates, summer students, and staff from local hospitals and museums, and will also serve as the primary physical testing resources for the visiting faculty and undergraduates from University of Puerto Rico with which the Penn MRSEC has a NSF-supported Partnership for Research & Education in Materials (PREM) program. The SEF experience will give these users a sense of autonomy and excitement, and thereby foster enthusiasm and awareness of science in the broader society.With this grant, the Materials Research Science & Engineering Center at the University of Pennsylvania will establish a shared experimental facility to perform electrical, magnetic, thermal and optical measurements for interdisciplinary research and education.

The instruments will be housed in a single laboratory accessible to students and post-docs 24 hours a day. The goal is to establish a community of diverse users who will exchange ideas and expertise while working in close proximity.The requested instrument is a uniquely versatile being able to run many types of experiments. The instrument can accept either commercial or custom-made experimental inserts by virtue of a modular design. Since options can be shared between the new system and the existing one, the new acquisition considerably leverages existing resources. Researchers will be able to measure physical properties over a wide range of temperatures, from -271 oC to 140 oC, and in magnetic field strengths up to 9 Tesla. Many physical properties, such as electrical resistance, optical transmission, and magnetization, are strongly temperature- and magnetic-field dependent. The study of these properties using the requested instrument will allow physical scientists to understand the underlying mechanisms that control these properties, and thereby improve known materials and invent useful new materials.The intellectual merit of the proposed facility lies in its role as a potent catalyst for nucleating new interdisciplinary research, especially in material discovery. Since its arrival three years ago, the existing instrument has already stimulated collaborative activities among researchers with a wide variety of interests. Vigorous and unexpected programs have been established in medical physics, nanoscience, and organic electronics, which originated from exploratory studies in the new facility. The proposed instrument will support these activities while also ensuring that speculative 'seed' research can still take place for identifying future research directions.The broader impact of the proposed facility lies in the services and opportunities it offers to the science community of Philadelphia and beyond.

The experience of working in the facility will give non-traditional users a sense of autonomy and excitement, thereby fostering enthusiasm and awareness of science in the broader society.

通过重大研究仪器计划的奖项，宾夕法尼亚大学（PENN）的材料研究科学与工程中心（MRSEC）将建立共享的实验设施（SEF），以对跨学科研究和教育进行电气，磁，热和光学测量。 该设施将容纳一个新的量子设计物理属性测量系统（PPM），以及现有的PPM，已经开发出了独特的磁光功能。 SEF将每天24小时将这些乐器安置在可供学生访问的单个实验室中，并将其放置。 目的是建立一个由不同用户组成的社区，他们将在紧邻近距离工作时交换思想和专业知识。拟议的SEF将远远超过其部分的总和，并将大大利用现有资源。 PPMS系统可以通过其模块化设计共享实验插件，因此，新获得的系统不仅会为热运输和热量容量增加新的最新功能，而且还将“继承”高抗性，Kerr效果，磁性效果，磁性，光纤探测，旋转插入，旋转插入物，定制软件，定制软件以及伴随现有系统的经验。 SEF中的第二个PPM将通过允许实验的任何组合同时运行来减少用户的积压，并为建立和测试专门的家庭建造插件提供宝贵的仪器时间，以进行自定义测量。所提出的SEF的智力优点在于其作为对新的跨学科研究成核的有效催化剂的作用，尤其是在物质发现中。自三年前到达以来，现有的PPM已经激发了各种各样兴趣的研究人员的协作活动。 已经建立了金属-DNA，医学物理学，碳纳米管和纳米纤维，磁氧化氧化物和进行有机物的剧烈和意外的程序，其中大多数源自使用该仪器的探索性测量。现在，这些努力需要比目前更多的仪器时间，新材料进一步为宾夕法尼亚州无法获得的其他功能创造了新的需求。 拟议的SEF将显着扩大MRSEC功能，并为人工多功能氧化物薄膜和新颖的分子传导，半导体和旋转设备以及其他不可预见的活动创造探索性的努力。 SEF仪器的设计旨在易于使用和连续操作，并将吸引那些可能因缺乏经验而被拒绝或拒绝的用户开始进行复杂的测量。 SEF将利用本地医院和博物馆的本科生，夏季学生和工作人员，还将作为波多黎各大学的来访教师和本科生的主要物理测试资源，Penn MRSEC与NSF获得的材料研究和教育合作伙伴关系（PREM）计划。 SEF的经验将使这些用户具有自主性和兴奋感，从而促进了更广泛的社会的热情和对科学的认识。宾夕法尼亚大学的材料研究科学与工程中心将建立一个共同的实验设施，以进行跨学科，磁性，磁性和光学测量，以进行跨学科研究和教育。 该设施将容纳一个新的量子设计物理属性测量系统，还将结合一种已经开发出独特功能的现有仪器。 这些仪器将安置在学生可以访问的一个实验室中，每天24小时可容纳仪器。 目的是建立一个由不同用户组成的社区，他们将在紧邻近距离工作时交换想法和专业知识。该请求的仪器是一个独特的用途，能够运行多种类型的实验。 该仪器可以通过模块化设计接受商业或定制的实验插入物。由于可以在新系统和现有系统之间共享选项，因此新的采购大大利用了现有资源。 研究人员将能够在广泛的温度（从-271 OC到140 oC）上测量物理特性，并且在磁场强度最高为9特斯拉。许多物理特性，例如电阻，光传递和磁化强度，都依赖温度和磁场。使用请求的工具对这些特性的研究将使物理科学家能够了解控制这些特性的基本机制，从而改善已知材料并发明有用的新材料。该提议的设施的智力优点在于其作为对新的跨学科研究的有效催化剂的作用，尤其是在材料发现中。 自三年前到达以来，现有工具已经激发了各种各样兴趣的研究人员的合作活动。 在医学物理，纳米科学和有机电子产品中已经建立了剧烈而意外的计划，这些计划源自新设施的探索性研究。拟议的工具将支持这些活动，同时还可以确保投机性的“种子”研究仍可以进行确定未来的研究方向。拟议设施的更广泛影响在于它为费城及其他地区提供的服务和机会。这些仪器的设计旨在易于使用和连续运行，并将吸引那些可能因缺乏经验而被拒绝或拒绝的用户开始进行复杂的测量。该设施将利用本地医院和博物馆的本科生，夏季学生和员工，并将作为波多黎各大学的来访教师和本科生的主要物理测试资源，Penn MRSEC与NSF材料研究和教育合作（PREM）协作计划（PREM）协作计划。在设施中工作的经验将使非传统使用者具有自主性和兴奋感，从而增强了更广泛的社会的热情和对科学的认识。
