The University of Wisconsin Nanoscale Science and Engineering Center (UW NSEC) addresses grand challenges associated with directed assembly of nanoscale materials into functional systems and architectures through the use of self-assembly, chemical patterning, and external fields. To realize that mission, the NSEC includes interdisciplinary research teams to 1) explore and develop new materials and processes for advanced lithography in which self-assembling block copolymers are directed to adopt morphologies that advance the performance of nanomanufacturing processes, 2) explore directed assembly at the nanoscale through the synthesis of biologically-inspired organic nanostructures in which functional side-chains display unique ordering, in terms of both sequence along a backbone and three-dimensional arrangement in space, and 3) explore and harness non-equilibrium processes, including the use of external fields, to manipulate the assemble nanoscale objects, including particles and macromolecules in simple and complex fluids. The outcomes of the NSEC?s transformative and interdisciplinary activities are to revolutionize nanomanufacturing and the discovery and control of new materials and material architectures. Examples of applications of the NSEC?s fundamental research include bit patterned media for data storage, potential manufacturing techniques for the semiconductor industry to keep pace with Moore?s Law, new materials with antifungal properties, development of optical mapping platforms for high-throughput analysis of entire genes, and development of liquid-crystal plasmonic based sensors for toxicants and biomolecules. UW NSEC research teams are also proactively engaged in 1) investigating the biological effects and environmental fate of engineered nanoparticles, with a particular emphasis on understanding how surface chemistry impacts uptake and biological activity in a zebrafish embryo model and is influenced by environmental weathering, and 2) basic research on communication effects and public opinion that will help us build an in-depth, empirical understanding of the psychological processes through which lay audiences make sense of complex information conveyed through the Internet. Shared facilities support these efforts as well as provide state-of-the-art infrastructure for internal and external users from academia and industry alike. The breadth and scope of the research programs and associated investigators provide the foundation for extensive interactions with companies, particularly the semiconductor industry and members of the NSEC-enabled UW Advanced Materials Industrial Consortium. Finally, the NSEC operates an ambitious and unique education and outreach program aimed at cultivating the next generation of nanoscale science and engineering experts with diverse and interdisciplinary backgrounds. Key programs include research experiences for undergraduates, research experiences for teachers, an NSEC fellowship program, an international research program for graduate students with collaborators on five continents, SCI ENCountErs, a highly successful pilot after-school program involving the Boys and Girls Club of Dane County that excites predominantly middle school students from underrepresented groups with innovative hands-on science activities, and a partnership with the Independent Laboratory Access for the Blind project to increase access to scientific careers for those who are blind and visually impaired.

威斯康星大学纳米科学与工程中心 (UW NSEC) 通过使用自组装、化学图案化和外部场，解决与将纳米级材料定向组装成功能系统和架构相关的巨大挑战。 为了实现这一使命，NSEC 包括跨学科研究团队，以 1) 探索和开发用于先进光刻的新材料和工艺，其中自组装嵌段共聚物被引导采用可提高纳米制造工艺性能的形态，2) 探索定向组装通过合成受生物启发的有机纳米结构来实现纳米尺度，其中功能侧链在沿着主干的序列和空间中的三维排列方面表现出独特的排序，以及3）探索和利用非平衡过程，包括使用外部场来操纵组装纳米级物体，包括简单和复杂流体中的粒子和大分子。 NSEC 的变革性和跨学科活动的成果是彻底改变纳米制造以及新材料和材料结构的发现和控制。 NSEC 基础研究的应用示例包括用于数据存储的位模式介质、半导体行业与摩尔定律保持同步的潜在制造技术、具有抗真菌特性的新材料、用于高通量分析的光学映射平台的开发整个基因的研究，以及基于液晶等离子体的毒物和生物分子传感器的开发。 UW NSEC 研究团队还积极参与 1) 研究工程纳米颗粒的生物效应和环境命运，特别强调了解表面化学如何影响斑马鱼胚胎模型中的吸收和生物活性以及环境风化的影响，以及 2 ）关于传播效果和舆论的基础研究将有助于我们对非专业受众理解通过互联网传达的复杂信息的心理过程建立深入的、实证的理解。 共享设施支持这些努力，并为学术界和工业界的内部和外部用户提供最先进的基础设施。 研究项目和相关研究人员的广度和范围为与公司的广泛互动奠定了基础，特别是半导体行业和 NSEC 支持的威斯康星大学先进材料工业联盟的成员。 最后，NSEC 开展了一项雄心勃勃且独特的教育和推广计划，旨在培养具有多元化和跨学科背景的下一代纳米科学和工程专家。主要项目包括本科生研究经验、教师研究经验、NSEC 奖学金项目、与五大洲合作者合作的研究生国际研究项目、SCI ENCountErs（丹麦男孩女孩俱乐部参与的一项非常成功的课后试点项目）该县主要通过创新的实践科学活动来激发来自代表性不足群体的中学生的兴趣，并与盲人独立实验室访问项目合作，以增加盲人和视障人士获得科学职业的机会。
