Juan Valdez-Moreira is awarded a FY21 Mathematical and Physical Sciences Ascending Postdoctoral Research (NSF MPS-Ascend) Fellowship to conduct a program of research and activities related to broadening participation by groups underrepresented in Chemistry at the University of California at Berkeley. The project being performed by Juan Valdez-Moreira, entitled Synthesis and Studies of Single-Molecule Magnets Incorporating Strongly Coupled Two-Coordinate Metal Building Units, is to be conducted under the guidance of mentoring scientist Jeffrey R. Long. This project is supported by the Office of Multidisciplinary Activities in the Mathematical and Physical Sciences Directorate.Single-molecule magnets are discrete paramagnetic molecules that can behave as classical bulk magnets at low temperature. This proposal seeks to design and synthesize new linear single-molecule magnets that can serve as building blocks in the design of multinuclear systems that are linked by ligands that enforce large magnetic coupling. A goal is development of compounds that retain their magnetic properties at higher (more practical) temperatures. This work has potential for broad scientific impact because of its strong connections to areas such as data storage, quantum computing and dark matter detection. In addition to proposed synthetic studies, Dr. Valdez-Moreira will carry out outreach activities, with the aim of reaching non-scientific communities, and the goal of educating and sparking interest in topics related to the proposed research. He will work with local sections of the American Chemical Society, the Society for Advancement of Chicanos/Hispanics and Native Americans in Science, and other societies to help advance his broadening participation goals.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.

胡安·瓦尔迪兹 - 洛雷拉（Juan Valdez-Moreira）被授予21财年的数学和物理科学，上升博士后研究（NSF MPS-ASCEND）奖学金，以开展与加利福尼亚大学在伯克利大学化学领域不足的群体扩大参与的研究和活动计划。 Juan Valdez-Moreira执行的项目，标题为“合成”和对结合强耦合两坐标金属建筑单元的单分子磁铁的研究，应在指导科学家Jeffrey R. Long的指导下进行。 该项目得到了数学和物理科学局的多学科活动办公室的支持。各种分子磁铁是离散的顺磁分子，在低温下可以作为经典的散装磁铁行为。 该提案旨在设计和合成新的线性单分子磁铁，这些磁铁可以用作设计多核系统设计的基础，这些系统由强制执行大型磁性耦合的配体连接起来。 一个目标是开发在较高（更实用的）温度下将其磁性保留的化合物的开发。 这项工作具有广泛的科学影响，因为它与数据存储，量子计算和暗物质检测等领域有着牢固的联系。 除了提出的合成研究外，瓦尔迪兹 - 洛雷拉（Valdez-Moreira）博士还将开展外展活动，目的是吸引非科学社区，以及对与拟议研究相关的主题进行教育和引发兴趣的目标。 他将与美国化学学会的当地部分，奇卡诺斯/西班牙裔和美洲原住民的科学发展协会以及其他社会合作，以帮助促进他的扩大参与目标。该奖项反映了NSF的法定使命，并被认为是通过基金会的智力和更广泛的影响来通过评估来获得支持的，并被认为是值得的。
