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形成连贯的结构和电子理解。 主要关注点是复杂的贵金属和近贵金属结构。通过这项工作，萨姆森化合物、游标结构和准晶相之间的新理解和关系将得到发展，并且可以统一这些看似不相关的领域。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考虑使用 X 射线衍射和能带理论的方式。此外，这些拟议的研究可能为准晶体的结构和电子特性提供重要的见解。 该项目可以为参与该项目的学生提供材料科学实验和理论方法的独特机会。外展活动可能会对社会产生巨大影响，尤其是有关科学和化学的书籍和电视连续剧。 “第四维度”是一个重要且有用的概念，可以以一种易于理解和有意义的方式向公众介绍。
