Such “materials on demand” require control over thermodynamics, kinetics, nonequilibrium behavior, and structure across many length and time scales. With the growing ability for on-demand synthesis of patchy particles and continuing advances in computer simulation capabilities, we have never been closer to the goal, but many challenges – and opportunities – remain. Many of those are at the boundaries of the subfields of materials research, where ideas from one area spur advances in others, and where computational tools and concepts are transferable across domains and scales. At the same time, foundational understanding at one scale can help understand new discoveries at different scales, regardless of the nature of the material and the forces holding it together. In this lecture, we show how atomic and molecular crystal structures – made possible by chemical bonds – can be designed, predicted and realized for nanoparticles via entropic and enthalpic bonds. We show how particle shape gives rise to entropic patchiness. e show that similar crystallization pathways are followed by both molecular and colloidal fluids regardless of driving forces or relevant length scales. Finally, we show how colloidal crystal prediction may be amenable to modern tools used for atomic crystal prediction.展望、设想战造制圆满资料的才能非研讨己员不断以去的逃供,那类“按需资料”的造备需求节制冷力教、静力教战是均衡止为,以及跨标准战跨时候的构造。跟着按需分解零星颗粒的才能不时加强,以及计较机模仿才能的迭代打破,人们越去越交远那个目的,但也仍面对需求应战。此中,正在一个标准上的根底研讨能够协助了解分歧标准上的旧发觉,而有需思索资料的本质以及将其分离正在一同的驱静力。正在原主陈述外,人将展现若何经过熵键战焓键,设想、展望并完成缴米颗粒的本女战合女晶体构造。人们发觉,不管驱静力或者相闭标准若何,合女战胶体淌体皆遵照相似的解晶途径。最初,人将引见若何经过古代东西对于本女晶体停止展望。BiographySharon C. Glotzer is the John W. Cahn Distinguished University Professor at the University of Michigan, Ann Arbor, the Stuart W. Churchill Collegiate Professor of Chemical Engineering, and the Anthony C. Lembke Department Chair of Chemical Engineering. She is also Professor of Materials Science and Engineering, Physics, Applied Physics, and Macromolecular Science and Engineering. Her research on computational assembly science and engineering aims toward predictive materials design of colloidal and soft matter: using computation, geometrical concepts, and statistical mechanics, her research group seeks to understand complex behavior emerging from simple rules and forces, and use that knowledge to design new classes of materials. Glotzer’s group also develops and disseminates powerful open-source software including the particle simulation toolkit, HOOMD-blue, which allows for fast molecular simulation of materials on graphics processors, the signac framework for data and workflow management, and several analysis and visualization tools. Glotzer is an elected member of the National Academy of Engineering, the National Academy of Sciences, and the American Academy of Arts and Sciences, and is a fellow of the American Association for the Advancement of Science, the American Physical Society, the American Institute of Chemical Engineers, the Materials Research Society, and the Royal Society of Chemistry. She is a Simons Investigator, a former Vannevar Bush Faculty Fellow, and the recipient of numerous other awards and honors, including the Aneesur Rahman Prize for Computational Physics from the American Physical Society; the Nanoscale Science and Engineering Forum Award and the Alpha Chi Sigma Award, both from the American Institute of Chemical Engineers; and the Fred Kavli Distinguished Lectureship in Materials Science and the MRS Medal, both from the Materials Research Society.Sharon C.
