通过发现新材料的合适特性，科学技术取得了重大进步。物理性能测量系统(PPMS)将允许对正在研究的潜在应用于食品科学、生物材料和电子设备的新材料进行表征，这些材料对促进国家健康、繁荣和福利至关重要。几种实验技术和PPMS中的自动化相结合，形成了一种强大的研究工具，能够提供探索新材料类别所需的高质量数据。这种最先进的仪器能够对学生和博士后进行研究培训，使本科生和研究生的工程和科学实验室课程受益，并扩展了俄克拉荷马州立大学现有的专注于材料研究的教育推广计划。该项目由重大研究仪器计划和已建立的激励竞争性研究计划(EPSCoR)共同资助。俄克拉荷马州立大学(OSU)要求建立物理性能测量系统(PPMS)。Quantum Design PPMS是一种开放式架构、可变温度和磁场系统，旨在执行各种自动化测量。该仪器将具有以下技术特点：带有9特斯拉磁铁的PPMS系统、DyaCool稀释冰箱、直流电阻率测量模块、振动样品磁测量、交流磁化率/直流磁化测量、范德堡测量、水平样品旋转器、热容量测量系统、热传输测量以及带有光电导台的XYZ压电和光学多功能探头。这种最先进的PPMS将用于一系列科学挑战的研究，包括金属-半导体界面热电子注入的检测、生物材料的热性能测量、热释电材料表面的传输、辐射对大型强子对撞机材料电子性能的影响、抗辐射电子学以及超导氧化物和拓扑材料的电子性能。其他受影响的研究领域包括对承载Skyrmions的材料的磁性测量、面筋复合材料的热性能以及纳米材料的表征。为了促进研究和教学并最大限度地实现多用户访问，PPMS将具有高水平的曝光率，并以低成本向俄克拉何马州的所有OSU研究人员和研究人员提供。该项目由重大研究工具计划和既定的激励竞争性研究计划(EPSCoR)共同资助。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Significant advances in science and technology have been made by discovering suitable properties of new materials. The Physical Property Measurement System (PPMS) will allow the characterization of new materials being investigated for potential applications in food science, biomaterials, and electronic devices, which are essential to advancing national health, prosperity, and welfare. The combination of several experimental techniques and automation in the PPMS results in a powerful research tool capable of providing the high-quality data needed to explore new classes of materials. This state-of-the-art instrument enables the research training of students and postdoctoral associates, benefits undergraduate and graduate engineering and science laboratory courses, and extends education outreach programs focused on materials research that are in place at Oklahoma State University. This project is jointly funded by the Major Research Instrumentation program and the Established Program to Stimulate Competitive Research (EPSCoR). Oklahoma State University (OSU) requests a Physical Property Measurement System (PPMS). The Quantum Design PPMS is an open architecture, variable temperature, and magnetic field system designed to perform a variety of automated measurements. The instrument will have the following technical features: a PPMS system with a 9 Tesla magnet, DynaCool dilution refrigerator, modules for DC resistivity measurements, vibrating sample magnetometry, ac susceptibility/dc magnetization measurements, Van der Pauw measurements, horizontal sample rotator, heat capacity measurement system, thermal transport measurements, and the xyz piezo and optical multi-functional probe with a photoconductivity stage. This state-of-the-art PPMS will be used for research into a broad range of scientific challenges, including detection of hot electron injection across metal-semiconductor Interfaces, thermal property measurement of biomaterials, transport at the surface of pyroelectric materials, the impact of radiation on the electronic properties of materials for the Large Hadron Collider, radiation-hard electronics, and electronic properties of superconductive oxides and topological materials. Other research areas impacted include magnetic measurements of materials hosting skyrmions, gluten composites' thermal properties, and nanomaterials' characterization. To promote research and teaching and maximize multi-user access, the PPMS will have a high level of exposure and be available at a low cost to all OSU researchers and researchers across Oklahoma. This project is jointly funded by the Major Research Instrumentation program and the Established Program to Stimulate Competitive Research (EPSCoR).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.
