Nathanael Hunter is awarded an 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. Hunter supports the research project entitled “MPS-Ascend: Ring-opening of Cyclic Ethers Facilitated by Main-group Lewis Acids” under the mentorship of a sponsoring scientist. The host institution for the fellowship is Texas A&M University, and the sponsoring scientist is Dr. François Gabbaï. This proposal intends to develop organoantimony (V) and organo-bismuth (III) compounds as Lewis acid tunable catalysts to facilitate the ring opening of oxetane including copolymerization with carbon dioxide. These catalysts will lead to better selectivity and to the development of new chemical transformations. The organo-bismuth catalysts, through a coordinating phosphine donor, will allow the introduction of a chiral ligand to the bismuth center, which will generate chiral oxetane ring-opening products. The low environmental hazards associated with bismuth will also push this chemistry in a more sustainable direction.The PI intends to participate in outreach activities to further increase the diversity, equity and inclusion all people studying chemistry. The PI plans to continue mentoring undergraduate and early graduate students at Texas A&M University, with a specific goal to increase the participation of students from underrepresented groups in graduate-level research in chemistry. The PI plans to join several outreach programs to educate primary and secondary school students about chemistry at a young age, to further engage the interest of future chemists. The PI also plans to develop a new hands-on educational program at Texas A&M University to prepare high school students in the greater Brazos County area for future careers in the chemical sciences.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.

Nathanael Hunter被授予NSF数学和物理科学的上升博士后研究奖学金（NSF MPS-ASCEND），以开展与STEM中代表性不足的团体扩大参与有关的研究和活动计划。在赞助科学家的心态下，与Hunter博士的这一奖学金支持了题为“ MPS-ASCEND：由主要群体刘易斯酸促进的环状醚开环”的研究项目。奖学金的主持机构是德克萨斯A＆M大学，赞助科学家是弗朗索瓦·加巴博士。该提案旨在发展有机抗体（V）和有机孔（III）化合物作为Lewis Acid Acid可调节催化剂，以促进氧烷的环开口，包括与二氧化碳共聚。这些催化剂将提高选择性和新化学转化的发展。通过协调磷酸供体的有机苯甲酸催化剂将允许将手性配体引入鞭毛中心，该中心将产生手性的氧烷式环环式环。与二抗性相关的低环境危害也将使该化学反应更加可持续。PI打算参加外展活动，以进一步增加所有研究化学的人的多样性，公平性和包容性。 PI计划继续在德克萨斯A＆M大学进行心理化本科生和早期研究生，其特定目标是增加代表人数不足小组的学生参与化学研究生水平研究。 PI计划加入多个外展计划，以教育小学和中学生在很小的时候就化学的教育，以进一步吸引未来化学家的兴趣。 PI还计划在德克萨斯州A＆M大学制定一项新的动手教育计划，以使大布拉索斯县地区的高中生在化学科学领域的未来职业做好准备。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子功绩和更广泛的影响审查标准来通过评估来诚实地支持。
