The work is a cooperative effort between the University of Utah and Kazan State University in Russia. The work is based on sintered silica colloidal crystals (nano-frits) with the goal of developing membranes containing nanoscale pores whose surface is modified with thiacalixarene receptors. These receptors, capable of binding ions, small molecules and biomacromolecules, will be covalently attached to the nanopore surface, which will produce nanoporous membranes with selective and environmentally responsive molecular transport. The US and Russian teams possess expertise in the fields of surface-modified silica nanoporous materials and synthesis of thiacalixarenes, respectively. The two groups will complement each other in creating new types of nanoporous materials that will find applications in separations and sensing. Furthermore, this work will be of mutual interest and importance as the two groups will contribute equally to the research and will bring to the table two sets of skills, otherwise not available.The interaction between the two teams will use cyberinfrastructure. Specifically, infrastructure will be built to enable the interaction between the two research groups using the Internet and videoconferencing. Two conference rooms, at the US and the Russian team locations, are built and equipped for videoconferencing and face-to-face interactions over the Internet. Thus, joint meetings will be conducted every month with the participation of all students and researchers involved in the project. Moreover, this infrastructure will enable everyday communication between researches working in two labs, which will greatly facilitate the cooperative effort. Also, students from both research teams will participate in one extended (1-3 months) stay each year in the counterpart university. In addition, exchange visits of senior participants will take place once a year for 1-2 weeks. These visits will include formal presentations to the research groups and departmental seminars, as well as informal interactions. All these interactions will expose the students and researchers in both cooperating groups to new scientific approaches and methods, and will widen their cultural horizons.This award is co-funded by the Division of Materials Research and the Office of International Science and Engineering.

这项工作是犹他州大学和俄罗斯喀山州立大学的合作成果。 这项工作是基于烧结的二氧化硅胶体晶体（纳米玻璃料），其目标是开发含有纳米级孔的膜，其表面用硫杂杯芳烃受体修饰。 这些受体，能够结合离子，小分子和生物大分子，将共价连接到纳米孔表面，这将产生具有选择性和环境响应性分子运输的纳米多孔膜。 美国和俄罗斯团队分别拥有表面改性二氧化硅纳米多孔材料和硫杂杯芳烃合成领域的专业知识。 这两个小组将在创造新型纳米多孔材料方面相互补充，这些材料将在分离和传感方面得到应用。 此外，这项工作将具有共同的利益和重要性，因为两个小组将对研究做出同等贡献，并将带来两套技能，否则无法获得。 具体而言，将建立基础设施，使两个研究小组能够利用因特网和电视会议进行互动。 在美国和俄罗斯团队所在地建造了两个会议室，并配备了视频会议和通过互联网进行面对面互动的设备。 因此，将每月举行一次由参与该项目的所有学生和研究人员参加的联席会议。 此外，该基础设施将使在两个实验室工作的研究人员之间能够进行日常交流，这将大大促进合作努力。此外，来自两个研究团队的学生将参加一个延长（1-3个月）留在对口大学每年。 此外，高级参与者每年将进行一次为期1-2周的互访。 这些访问将包括向研究小组和部门研讨会的正式介绍，以及非正式的互动。 所有这些互动将使两个合作小组的学生和研究人员接触到新的科学方法和手段，并将拓宽他们的文化视野。该奖项由材料研究部和国际科学与工程办公室共同资助。
