IRES: Nanofibers for Resource EfficiencyA thematic basis of this program is the emerging area of nanofibers. Nanofibers have diameters from one to four orders of magnitude smaller than the diameters of conventional microfibers produced by mechanical drawing. As a result of their small size, nanofibers can demonstrate superior properties that provide critical advantages in many applications. Nanofibers (NF) are increasingly explored in high performance filtration, batteries and fuel cells, wound healing, composite material reinforcements, blood vessel and tissue engineering, smart textiles, drug delivery, gas sensors, electronics, and catalysis. The global market for NF is expected to grow at an annual growth rate of 35% between 2014 and 2020 and reach ~$1 billion by 2017. There are huge needs in the development of sizeable and ?green? production of NF from a larger range of materials, providing easier ways for NF processing into functional structures, and developing a skilled workforce. This IRES will provide at least 18 undergraduate and graduate students from the University of Alabama at Birmingham with unique hands-on experience and significant knowledge of cutting-edge NF fabrication methods, as well as NF testing and application by providing an intense research program at the Technical University of Liberec (TUL), Czech Republic, a leading academic center in nanofiber research and commercialization, and at the Lodz University of Technology (UT-Lodz), a regional leader in catalysis and bio-fuels in Poland. Students will develop practical skills needed to address the knowledge gaps in NF science and technology, bring their experiences back to their home institutions, and help to develop a global-capable workforce for this emerging market. By using a cohesive approach and drawing on complementary expertise, facilities and traditions across the nations and regions, will enhance the intellectual as well as the societal and economic returns of this IRES program.This program will provide 18 students from the University of Alabama at Birmingham with a unique opportunity to carry out 8 week of cutting-edge research at the forefront of nanofiber science, technology, and biomedical and energy applications at the Technical University of Liberec (TUL), Czech Republic, a leading academic center in nanofiber research and commercialization, and at the Lodz University of Technology (UT-Lodz), a regional leader in heterogeneous catalysis, Poland. Nanofibers (NF) form a large class of materials that can exhibit nano-enabled unique properties, which are unattainable at a larger scale. However, the growth potential of the NF materials market is still hindered by the limited ability to efficiently generate sizeable quantities of nanofibers with predictable and controllable complex, macroscopic architectures and desirable properties. Students will work at TUL with a new, high-rate, alternating-current electrospinning (ac-electrospinning) process that unveils several new physical phenomena which help to overcome major disadvantages of commonly used dc-electrospinning, such as ?whipping? instability and residual electric charge, while increasing the process productivity by 1 ? 2 orders of magnitude. Students will explore selected NF-based materials for advanced catalytic systems with improved activity, selectivity and stability in many reactions at UT-Lodz, along with other applications tested at TUL. During the pre-trip training, foreign site work, and post-trip activities, students will focus on advancing basic understanding of all aspects of emerging high-rate ac-electrospinning, in order to direct the assembly of NF into desired configurations and to stimulate the development of commercializable processes for nanofiber-based materials for heterogeneous catalysis, biomedical uses, and other potential applications. Overall, this program shall facilitate a broader long-term collaboration between the US and international research groups within the nanofiber research and manufacturing domain by bringing new collaborators and facilitating multiple international links between the researchers and students in related areas.

IRES：纳米纤维的资源效率这一计划的主题基础是纳米纤维的新兴领域。纳米纤维的直径比通过机械拉伸生产的常规微纤维的直径小一至四个数量级。 由于其小尺寸，纳米纤维可以表现出在许多应用中提供关键优势的上级性质。 纳米纤维（NF）在高性能过滤、电池和燃料电池、伤口愈合、复合材料增强、血管和组织工程、智能纺织品、药物输送、气体传感器、电子和催化方面的应用越来越多。预计2014年至2020年间，全球NF市场将以35%的年增长率增长，到2017年将达到约10亿美元。 有巨大的需求，在发展规模和？绿色？从更大范围的材料生产NF，为NF加工成功能结构提供更简单的方法，并培养熟练的劳动力。 该IRES将为来自伯明翰亚拉巴马大学的至少18名本科生和研究生提供独特的实践经验和尖端NF制造方法的重要知识，以及NF测试和应用，通过在捷克共和国利贝雷茨技术大学（TUL）提供密集的研究计划，这是一个领先的学术研究和商业化中心，以及波兰催化和生物燃料领域的区域领导者罗兹理工大学（UT-Lodz）。学生将培养解决NF科学和技术知识差距所需的实用技能，将他们的经验带回他们的家乡机构，并帮助为这个新兴市场培养具有全球能力的劳动力。通过使用一个有凝聚力的方法和借鉴互补的专业知识，设施和传统的国家和地区，将提高智力以及社会和经济回报的IRES计划。该计划将提供18名学生从亚拉巴马大学伯明翰分校与一个独特的机会，进行8周的尖端研究前沿的科学，技术，在捷克共和国利贝雷茨技术大学（TUL），一个领先的学术中心，在催化剂研究和商业化，并在罗兹技术大学（UT-Lodz），在多相催化的区域领导者，波兰的生物医学和能源应用。 纳米纤维（NF）形成了一大类材料，可以表现出纳米使能的独特性能，这是在更大的规模上无法实现的。 然而，NF材料市场的增长潜力仍然受到有效产生大量具有可预测和可控的复杂、宏观结构和理想性能的纳米纤维的能力有限的阻碍。 学生将在TUL工作，采用一种新的，高速率，交流电纺（交流电纺）过程，揭示了几种新的物理现象，有助于克服常用的直流电纺的主要缺点，如？鞭打？不稳定性和残余电荷，同时增加1？两个数量级。学生将探索先进的催化系统，提高活性，选择性和稳定性，在UT-罗兹，沿着在TUL测试的其他应用程序的许多反应选择NF基材料。 在旅行前的培训，国外现场工作和旅行后的活动中，学生将专注于推进对新兴的高速交流静电纺丝的各个方面的基本理解，以指导NF的组装成所需的配置，并刺激开发基于纳米纤维的材料用于多相催化，生物医学用途和其他潜在应用的商业化过程。 总的来说，该计划将通过引入新的合作者并促进相关领域研究人员和学生之间的多个国际联系，促进美国和国际研究小组在生物技术研究和制造领域之间更广泛的长期合作。
