This Materials World Network award to Case Western Reserve University is to promote cooperative research in materials between US investigators and their counterparts from two German institutions, namely the Max Planck Institute of Microstructure Physics in Halle and the University of Paderborn, in the design, preparation and study of photonic crystals (PCs) with a dynamic or nonlinear band gap. This award, co-funded and managed by the Electronic Materials program in the Division of Materials Research, aims to create and study hybrid materials based on macroporous silicon and titania and consciously designed organic third-order nonlinear optical materials. These activities include: (i) the design, fabrication and characterization of ordered porous substrates and devices that form the basis for PCs with dynamic band gaps; (ii) the synthesis of tailor-made low-molecular weight and polymeric organic nonlinear optical chromophores which exhibit large optical nonlinearities and appropriate physico-chemical properties to wet and fill the porous substrates; (iii) the study of the infiltration mechanisms along with the investigation of the formation of mesophases inside the pores; and (iv) the optical characterization of the bulk properties of the nonlinear optical materials and devices based on inorganic/organic photonic hybrid systems. These structured materials are characterized by a spatially periodic variation of the dielectric permittivity and, due to the use of nonlinear optical materials, display variable optical properties. Materials with dynamic optical band gap may form the physical basis for ultra-fast optical switches, which are of considerable technological interest and could enable a plethora of applications that range from high-density optical data processing to adaptive optics to high-throughput communications systems. This award is also co-funded by the Western Europe Program in the Office of the International Science and Engineering. The proposed research is at the interface of materials chemistry, polymer science and engineering, inorganic microfabrication, as well as optical and device physics. It contributes new and original ideas to the current international efforts focused on the creation of a new class of optical materials, the fundamental understanding of these systems and their exploitation in technologically relevant applications. The award would result in new knowledge and materials that potentially will benefit society by the creation of new products and technologies. The research activities are designed to integrate research and education, to provide an exciting learning environment and to create teaching opportunities for graduate and undergraduate students. The interdisciplinary research approach and the planned exchange programs would have long-lasting beneficial relationship between US and German researchers at all levels. The proposed research draws on and supports research infrastructure assembled through federal and state grants at Case Western Reserve University. A partnership with the Cleveland Museum of Natural History promises to enhance the scientific and technological education of the public and outreach to children from inner city schools.

Case Western Reserve University的这项材料世界网络奖是为了促进美国调查人员与其同行之间的材料合作研究，即Halle的Max Planck Microscructure Physics和Paderborn大学的Max Planck Microsconture Institute in Dynamic Crystals（PCS）具有动态或非线性晶体带隙的设计，准备和研究。该奖项由材料研究部的电子材料计划共同资助和管理，旨在基于大孔和泰坦尼亚和有意识地设计有机的三阶非线性光学材料来创建和研究混合材料。这些活动包括：（i）构成具有动态带隙的PC的基础的有序多孔基板和设备的设计，制造和表征； （ii）量身定制的低分子重量和聚合有机非线性光发色团的合成，它们表现出较大的光学非线性和适当的物理化学特性，以湿润并填充多孔底物； （iii）研究浸润机制，以及孔内中期的形成的研究； （iv）基于无机/有机光子杂交系统的非线性光学材料和设备的块状特性的光学表征。这些结构化材料的特征是介电介电常数的空间周期性变化，并且由于使用非线性光学材料，因此显示出可变的光学性能。具有动态光节间隙的材料可能构成超快速光学开关的物理基础，这些开关具有很大的技术兴趣，并且可以实现从高密度光学数据处理到自适应光学到高通量通信系统的大量应用。 该奖项也由西欧计划在国际科学与工程办公室共同资助。拟议的研究是在材料化学，聚合物科学和工程，无机微结合以及光学和设备物理学的界面上。它为当前的国际努力做出了新的和原创的想法，重点是创建新的光学材料，对这些系统的基本理解及其在技术相关应用中的剥削。 该奖项将导致新知识和材料通过创建新产品和技术有可能使社会受益的新知识和材料。研究活动旨在整合研究和教育，提供令人兴奋的学习环境，并为研究生和本科生创造教学机会。跨学科的研究方法和计划的交流计划将在美国与德国研究人员之间建立长期的有益关系。拟议的研究借鉴并支持通过凯斯西部储备大学联邦和州赠款组成的研究基础设施。与克利夫兰自然历史博物馆的合作伙伴关系有望增强公众的科学和技术教育，并与内城学校的儿童进行宣传。
