项目摘要

CBET-0821556ThompsonRecently, electromagnetic radiation in the terahertz frequency range, best known as terahertz rays (T-rays), has emerged as one of the most promising energy forms for measurement in a variety of applications in science and engineering. T-rays, residing in a relatively unexplored region between the microwave and infrared, are considered by many to be the last frontier in the electromagnetic spectrum. This has recently become accessible because of instrumentation advances and the acquisition of a system for T-ray imaging and spectroscopy is proposed. Initial interest in this system at Iowa State University was motivated by a number of applications in physics, chemistry and engineering, and includes applications to the characterization of photonic and metamaterials, solvation of ionic liquids, fundamental studies of multiphase combustion and flow processes, nondestructive evaluation of composite materials, and bioengineering. Given the newness and limited availability of such equipment, there will doubtlessly be numerous applications that are not initially expected. Accordingly, a portion of the user time will be set aside for innovative exploratory projects. In addition time will be made available to users from other institutions to allow others to explore these special opportunities. The intellectual merit of the proposed equipment acquisition is extremely high, as would be expected when a new measurement frontier is opened. Among the reasons for this is the fact that the newly accessible terahertz frequency regime is one in which molecular resonances dominate. Accordingly, the absorption spectra of T-rays exhibit distinct signatures for substances such as water vapor, polar plastics, certain gases, DNA, crystalline solids, biofuel feedstocks and explosives. Examples of problems in which unique experimental information can be obtained by this technique are identified in the project areas described above and developed in greater detail in the proposal. The proposing team is in an excellent position to investigate these because of its strong experimental and theoretical programs in condensed matter physics, chemistry, combustion and environmental engineering, nondestructive evaluation and other areas of science and engineering. It is also anticipated that new interdisciplinary opportunities will manifest themselves as this broad group works in a common facility. The dedication of a portion of the user time to innovative exploratory projects and collaborative users from other institutions is designed to maximize the opportunity for exploratory research. Significant Broader benefits to society will be a natural outcome of this instrumentation acquisition. In addition to fundamental scientific studies, applications of T-rays are rapidly emerging in a number of areas including the automotive, aviation, food, energy, materials, pharmaceuticals, medical diagnosis, forensics, defense, and homeland security. It can be expected that broad advances in such areas can be expected based on accessibility to the proposed equipment. The intellectual excitement associated with a new scientific tool, along with the existence of practical applications that have major benefit to society, will make this an area of significant interest to students. In addition to the obvious education of graduate and undergraduate students that will occur, this forefront instrumentation will serve as a magnet that will be a centerpiece in efforts to recruit and educate a more diverse student body. As an example, the Principal Investigator is currently engaged in programs aimed at increasing the involvement of Hispanic, African American and Native American students, and the facility built around this instrumentation should increase the attractiveness of those programs.
CBET-0821556 WEBSON最近,太赫兹频率范围内的电磁辐射,最为人所知的是太赫兹射线(T射线),已经成为科学和工程中各种应用中最有前途的测量能量形式之一。T射线位于微波和红外线之间相对未被探索的区域,被许多人认为是电磁波谱中的最后一个前沿。由于仪器的进步,这一点最近已经变得容易实现,并提出了一种用于T射线成像和光谱学的系统。爱荷华州州立大学最初对该系统的兴趣是由物理、化学和工程方面的一些应用引起的,包括光子和超材料的表征、离子液体的溶剂化、多相燃烧和流动过程的基础研究、复合材料的无损评价和生物工程。鉴于这种设备的新颖性和有限的可用性,无疑会有许多最初没有预料到的应用。因此,将留出一部分用户时间用于创新性探索项目。此外,还将为其他机构的用户提供时间,使其他人能够探索这些特殊机会。拟议的设备采购的知识价值极高,正如在开辟新的测量领域时所预期的那样。其中一个原因是,新获得的太赫兹频率范围是分子共振占主导地位的频率范围。因此,T射线的吸收光谱表现出对诸如水蒸气、极性塑料、某些气体、DNA、结晶固体、生物燃料原料和爆炸物等物质的不同特征。通过这种技术可以获得独特的实验信息的问题的例子在上述项目领域中被确定,并在提案中更详细地阐述。提议的团队处于一个很好的位置来调查这些,因为它在凝聚态物理,化学,燃烧和环境工程,无损评估和其他科学和工程领域的强大的实验和理论计划。还预计,新的跨学科的机会将体现在这一广泛的群体在一个共同的设施。将一部分用户时间用于创新的探索性项目和来自其他机构的合作用户,旨在最大限度地增加探索性研究的机会。对社会的重大更广泛的利益将是这一仪器收购的自然结果。除了基础科学研究之外,T射线的应用也迅速出现在许多领域,包括汽车、航空、食品、能源、材料、制药、医疗诊断、法医、国防和国土安全。可以预期,根据拟议设备的可获得性,这些领域将取得广泛进展。与新的科学工具相关的智力兴奋,沿着对社会有重大利益的实际应用的存在,将使这成为学生感兴趣的领域。除了将发生的研究生和本科生的明显教育,这个前沿仪器将作为一块磁铁,将是努力招募和教育更多样化的学生群体的核心。例如,首席研究员目前正在从事旨在增加西班牙裔,非洲裔美国人和美洲原住民学生参与的项目,围绕这种仪器建造的设施应该会增加这些项目的吸引力。
