This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Mikaela Pyrch is awarded a NSF Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship (NSF MPS-Ascend) to conduct a program of research and activities related to broaden participation by groups underrepresented in STEM. This fellowship to Dr. Pyrch supports the research project entitled MPS-Ascend: "Rigid Oxo Ligands to Control the Next Generation of f-Element Molecular Spin Centers.", under the mentorship of a sponsoring scientist. The host institution for the fellowship is the University of California Berkeley, and the sponsoring scientist is Dr. Polly Arnold. The proposed work intends to determine how the identity of rigid, oxygen donating, axial ligands influence the electronic, magnetic, and optical properties of the Er(III) cation through stabilization of ground levels. Objectives of the work include identification of rigid, highly symmetric, axial ligands to stabilize the lowest spin orbital coupled state using linear actinyl cations as oxygen donor ligands; assessment of the impact of the coordination environment on magnetic properties within Er complexes; and to evaluate the role of the coordination environment on the optical properties of the Er center. Successful implementation of the work will increase the understanding of spin-phonon and spin-spin relaxation processes in prolate lathanides. Implementation of this work will provide the opportunity to work with historically excluded minority groups at the grade school level. Projects such as crystal growth will provide hands-on introduction to synthetic chemistry which will promote critical thinking and connect observations to chemistry fundamentals. These activities have the potential to provide a foundation for students to develop into future scientists.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.

该奖项是根据2021年《美国救援计划法》（公法117-2）全部或部分资助的。 Mikaela Pyrch被授予NSF数学和物理科学，上升博士后研究奖学金（NSF MPS-ASCEND），以开展一项与STEM中代表性不足的团体扩大参与的研究和活动计划。 Pyrch博士的这一奖学金支持题为MPS-ASCEND的研究项目：“在赞助科学家的指导下，控制下一代F-元素分子旋转中心的僵硬的Oxo配体。”奖学金的主持机构是加利福尼亚大学伯克利分校，赞助科学家是Polly Arnold博士。 提出的工作旨在确定刚性，氧气，轴向配体的身份如何通过稳定地面水平来影响ER（III）阳离子的电子，磁性和光学特性。工作的目标包括识别刚性，高度对称的轴向配体，以使用线性阳离子阳离子作为氧供体配体稳定最低的旋转轨道耦合态；评估协调环境对ER复合物内磁性特性的影响；并评估协调环境对ER中心光学特性的作用。成功实施这项工作将增加对pr酸lathanides中自旋 - 旋转松弛过程的理解。这项工作的实施将为与历史上排除的少数群体在小学一级合作提供机会。水晶增长等项目将为合成化学提供动手介绍，这将促进批判性思维并将观察结果与化学基本面联系起来。这些活动有可能为学生发展成未来的科学家的基础。该奖项反映了NSF的法定使命，并被认为是值得通过基金会的知识分子优点和更广泛影响的评论标准来评估值得支持的。
