This award by the Division of Materials Research to Cornell University is to develop a coherent structural and electronic understanding of hidden patterns and symmetries of intermetallic compounds through synthesis, structure determination, property measurement, and theory. The main focus will be on complex noble and near noble metal structures. Through this work a new understanding and relationship among the Samson compounds, the Vernier structures and quasicrystalline phases will be developed and could unify these seemly unrelated areas. This project could expand how solid-state chemists, condensed matter physicists, and materials scientists will consider using X-ray diffraction and band theory. In addition, these proposed studies may provide important insights into the structure and electronic characteristics of quasicrystals. The project could provide unique opportunities to the students participating in this program in experimental and theoretical approaches of materials science. The outreach activities could have tremendous impact on the society with books and TV series about sciences and chemistry in particular. The "fourth dimension" is an important and useful concept that could be introduced to general public in an understandable and meaningful way.

该奖项由康奈尔大学材料研究部颁发，旨在通过合成、结构测定、性能测量和理论，对金属间化合物的隐藏模式和对称性进行连贯的结构和电子理解。 主要重点将放在复杂的贵金属和近贵金属结构上。通过这项工作，将对参孙化合物、游标结构和准晶相之间的关系有一个新的认识和认识，并将这些完全不相关的领域统一起来。该项目可以扩展固态化学家，凝聚态物理学家和材料科学家将如何考虑使用X射线衍射和能带理论。此外，这些拟议的研究可能会提供重要的见解准晶体的结构和电子特性。 该项目可以提供独特的机会，参加该计划的学生在材料科学的实验和理论方法。这些外展活动可能会对社会产生巨大的影响，特别是有关科学和化学的书籍和电视连续剧。"第四维度"是一个重要和有用的概念，可以以一种可以理解和有意义的方式向公众介绍。
