The Major Research Instrumentation program supports the University of Puerto Rico Mayaguez with the acquisition of a cutting-edge multi-function Ultra Rapid Quenching Apparatus (URQA) for the synthesis of materials with amorphous, metastable phases and microcrystalline structures. URQA will be established as a facility for research and education and it will support and enhance the rapidly expanding research infrastructure in the field of energy conversion materials and on-going diverse and interdisciplinary research projects at the University of Puerto Rico at Mayagüez and Rio Padias campus. In addition to the significant cost saving for material acquisition, the URQA also provides opportunity for new research directions and for education and training in a diverse field by six researchers in three departments, i.e. Materials Engineering Science, Physics and Chemistry from two campuses, Mayaguez and Rio Padias. The URQA will support a new graduate program in Materials Science & Engineering, and it will be used in existing courses, as well as in new courses in materials engineering. In addition, the URQA research will be beneficial for regional industry. Approximately 15% of the instrument operating time will be dedicated to education and training.The instrument consists of a crucible-free levitation melting, which makes it well suited for melting reactive materials bearing high melting points. The instrument is also capable of high cooling rates of more than one million degree Kelvin per second. The materials are relevant to most fields in materials science and engineering. The instrument is unique in Puerto Rico and essential to supporting a diverse and interdisciplinary ongoing research projects. Specific research activities supported by the proposed URQA system include: (1)synthesis of clathrate materials and the study of magnetic, thermoelectric and superconducting properties;(2) nanostructured metastable systems for the synthesis of high strength wires for aerospace welding applications; (3)synthesis and processing of nanocomposite permanent magnets; (4)magnetic nanostructured materials for biomedicine application; and synthesis and physical properties of rare-earth intermetallic compounds.

主要研究仪器计划支持波多黎各Mayaguez大学收购先进的多功能超快速淬火装置（URQA），用于合成具有非晶，亚稳相和微晶结构的材料。URQA将作为一个研究和教育设施建立，它将支持和加强在能源转换材料领域迅速扩大的研究基础设施和正在进行的多样化和跨学科的研究项目在波多黎各大学马亚圭斯和里奥帕迪亚斯校园。除了材料采购的显着成本节约，URQA还提供了新的研究方向和教育和培训的机会，在不同的领域由六名研究人员在三个部门，即材料工程科学，物理和化学从两个校区，马亚圭斯和里约帕迪亚斯。URQA将支持材料科学工程的新研究生课程，它将用于现有课程以及材料工程的新课程。此外，URQA的研究将有利于区域产业。该仪器约15%的工作时间将用于教育和培训。该仪器由无坩埚悬浮熔炼组成，非常适合高熔点反应性材料的熔炼。该仪器还能够达到每秒超过一百万开尔文的高冷却速率。这些材料与材料科学和工程的大多数领域有关。该仪器在波多黎各是独一无二的，对于支持正在进行的多样化和跨学科研究项目至关重要。 拟议的URQA系统支持的具体研究活动包括：（1）笼形材料的合成以及磁性、热电和超导性能的研究;（2）用于合成航空航天焊接应用的高强度线材的纳米结构亚稳系统;（3）纳米复合永磁体的合成和加工;（4）用于生物医学应用的磁性纳米结构材料;（5）用于生物医学应用的磁性纳米结构材料;（6）用于生物医学应用的纳米结构材料;（7）用于生物医学应用的纳米结构材料;（8）用于生物医学应用的纳米结构材料。以及稀土金属间化合物的合成和物理性质。
