This Major Research Instrumentation supports Drexel University with the acquisition of a state-of-the-art scanning electron microscope (SEM) designed for advanced imaging and analysis. The instrument placed in the Materials Characterization Core (MCC) shared-instrumentation facility provides all-around performance for imaging and analysis. The SEM replaces an outdated instrument and enhances research outcomes for a broad user base including over 40 research groups at Drexel and several users from nearby universities and businesses. The instrument significantly benefits researchers at Drexel University and promotes collaboration between Drexel and nearby institutions such as Villanova University, Temple University, and Rowan University. In addition to the versatile research activities enabled by the proposed SEM, the new SEM enhances Drexel’s education and training experience considerably. The SEM is housed in and managed by an established core facility with full-time technical staff, with 15-year record for excellent stewardship of major instrumentation. The MCC promotes technical training of users such that they become proficient and independent users and partners with the University’s academic units to provide undergraduate and graduate students with hands-on experiences integrated into course curricula. It contributes to the outreach program sponsored by the MCC and academic units to introduce young people to nanoscience, engineering, and technological research.The acquisition of a state-of-the-art scanning electron microscope (SEM) significantly strengthens the strong in situ electron microscopy capability at Drexel, and helps accelerate/facilitate research and educational activities in four critical areas: (1) New Materials for Energy and Sustainability – Temperature control and in operando electrochemistry in the SEM drive the discovery of new materials, materials systems, and structures to optimize next-generation battery technologies. (2) Advanced Mechanical Property Characterization – In situ mechanical testing at controlled temperatures combined with high-resolution imaging and chemical mapping to advance understanding of deformation mechanisms in novel layered crystalline solids and biomaterials. (3) Engineering Soft Materials and Biomaterials – High spatial resolution chemical mapping and low-current, low-vacuum imaging to expand research into liquid-free conformal polymer coatings and enable characterization and taxonomic classification of rare, historic collections of microscopic, fossilized diatoms. In situ mechanical testing at controlled temperatures will advance the development of new adhesives, polymer nanocomposites, and hydrogels. (4) Advanced Electronic Materials – In situ heating stages combined with charge-free imaging of insulating samples will enable new experiments on complex oxide heterostructures designed. Similarly, in situ heating will advance efforts to understand and design efficient fabrication processes for novel quantum materials and devices.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.

这项主要的研究仪器通过获取用于高级成像和分析的最先进的扫描电子显微镜（SEM）来支持Drexel University。放置在材料表征核心（MCC）共享启蒙设施中的仪器为成像和分析提供了全面的性能。 SEM取代了过时的工具，并增强了广泛用户群的研究成果，其中包括Drexel的40多个研究小组以及来自大学和企业附近的几个用户。该工具可显着使Drexel University的研究人员受益，并通过Villanova University，Temple University和Rowan University等机构促进Drexel之间的合作。除了拟议的SEM启用的多功能研究活动外，新的SEM还可以大大增强Drexel的教育和培训经验。 SEM由拥有全职技术人员的既定核心设施内置并管理，并拥有15年记录，以实现出色的主要仪器管理。 MCC促进了对用户的技术培训，以使他们成为大学学术部门的熟练和独立用户以及合作伙伴，以向本科生和研究生提供整合到课程课程中的动手经验。 It contributes to the outreach program sponsored by the MCC and academic units to Introducing young people to nanoscience, engineering, and technical research.The acquisition of a state-of-the-art scanning electronic microscope (SEM) significantly strengthens the strong in situ electronic microscopy capability at Drexel, and helps accelerate/facilitate research and educational activities in four critical areas: (1) New Materials for Energy and Sustainability – Temperature control and in operado SEM中的电化学发现新材料，材料系统和结构的发现，以优化下一代电池技术。 （2）先进的机械性能表征 - 在受控温度下与高分辨率成像和化学映射相结合的原位机械测试，以提高对新型层状晶体固体和生物材料中变形机制的了解。 （3）工程软材料和生物材料 - 高空间分辨率化学映射和低流动性低空成像，以将研究扩展到无液体的共形聚合物涂层中，并促进对罕见的，历史悠久的微观，化石，化石diotoms的特征和分类分类。在受控温度下的原位机械测试将推动新粘合剂，聚合物纳米复合材料和水凝胶的发展。 （4）先进的电子材料 - 原位加热阶段与绝缘样品的无电荷成像相结合，将在设计的复杂氧化物异质结构上进行新的实验。同样，原位供暖将促进为新颖的量子材料和设备理解和设计有效的制造过程。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，通过评估被认为是珍贵的支持。
