Directed Synthesis of a Pure Spin Liquid - Towards a Comprehensive Theory of High-Tc Superconductivity

化学部支持马萨诸塞州理工学院的Danna Freedman作为美国化学竞争力研究员。 弗里德曼博士将与丹·诺塞拉教授合作，根据安德森的共振价键（RVB）理论，创造可用于制造高温超导体的材料的成分纯晶体。 这些晶体的合成将由阿贡国家实验室先进光子源的ChemMatCARS光束线上进行的一种新型异常X射线散射测量结果指导。 Freedman博士将与ChemMat汽车的研究光束线科学家Yu-Sheng Chen博士合作。 对于她扩大参与的计划，PI将与材料科学与工程中心合作开发化学课程，以及这与能源问题的关系，包括超导性，供当地中学生使用，包括来自代表性不足的群体的很大一部分。像弗里德曼博士这样的研究最终旨在开发更有效的电导体--可以在例如电力分配中产生更高效率的技术领域。 弗里德曼博士正在努力扩大参与，目的是鼓励各行各业的年轻人更好地了解科学，并尽可能从事科学事业。

The Division of Chemistry supports Danna Freedman of the Massachusetts Institute of Technology as an American Competitiveness in Chemistry Fellow. Dr. Freedman will work with Prof. Dan Nocera to create compositionally-pure crystals of materials which can be used to make high-temperature superconductors, according to Anderson's resonating valence bond (RVB) theory. The synthesis of these crystals will be guided by results from a new kind of anomalous x-ray scattering measurements made at the ChemMatCARS beamline of the Advanced Photon Source at Argonne National Laboratory. Dr. Freedman will be collaborating with Dr. Yu-Sheng Chen, a Research Beamline Scientist at ChemMat CARS. For her plan for broadening participation, the PI will work with the Center for Materials Science and Engineering to develop curriculum on chemistry and how this relates to energy issues, including superconductivity, to be used with local middle school students, including a significant fraction from underrepresented groups.Research like that of Dr. Freedman is aimed ultimately at developing more efficient electrical conductors -- a technology area that can yield greater efficiencies in e.g. electrical power distribution. The efforts at broadening participation being pursued by Dr. Freedman are aimed at encouraging young people from all walks of life to develop a better understanding of science and to possibly pursue careers in science.
