This U.S.-Slovene research project between Gregory Crawford of Brown University, Daniele Finotello of Kent State University, and Slobodan Zumer of the University of Ljubljana examines the structure and ordering of nematic liquid crystals confined to templates ranging from nano- to micro-sized dimensions. Postdoctoral fellows as well as graduate and undergraduate students from each institution will also participate on this international team. The multidisciplinary research plan involves three complementary areas: 1) nanoscale confinement utilizing prefabricated templates, 2) photo-self diffusion mediated templating, and 3) back-flow mediated templating. These latter two areas are a new thrust in synthesis and characterization of innovative structures created by photo-self-diffusion using multiple beam holography and the capturing of unusual structures created from back flow with photopolymerization. Several experimental techniques will be applied to understand the underpinning physics of these novel structures, including nuclear magnetic resonance techniques, light scattering, electro-optics, as well as theory and simulation. Results should improve our fundamental understanding of liquid crystals and their potential applications in emerging nano- and micro-scale technologies using soft condensed materials.This project in nanoscale materials fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. Broader impacts include the introduction of U.S. and Slovenian students to the international research community through work at partner institutions and direct involvement in the project's advanced characterization, modeling and fabrication techniques.

这个美国-布朗大学的Gregory Crawford、肯特州立大学的Daniele Finotello和卢布尔雅那大学的Slobodan Zumer在斯洛文尼亚进行了一项研究，研究了限制在纳米到微米尺寸的模板上的液晶的结构和有序性。 来自各机构的博士后研究员以及研究生和本科生也将参加这个国际团队。 多学科研究计划涉及三个互补领域：1）利用预制模板的纳米级限制，2）光自扩散介导的模板，和3）回流介导的模板。 这后两个领域是一个新的推力，在合成和表征的创新结构创建的光自扩散使用多光束全息和捕获的不寻常的结构创建的回流与光聚合。几种实验技术将被应用于理解这些新结构的基础物理，包括核磁共振技术，光散射，电光，以及理论和模拟。 结果应该提高我们对液晶的基本理解及其在新兴的纳米和微米级技术中使用软凝聚材料的潜在应用。该纳米级材料项目通过使美国和中欧的专家联合收割机互补人才和共享研究资源来实现推进科学知识的计划目标。更广泛的影响包括通过在合作机构工作和直接参与该项目的先进表征，建模和制造技术，将美国和斯洛文尼亚学生介绍给国际研究界。
