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.

化学部支持麻省理工学院的Danna Freedman成为美国化学竞争力研究员。根据安德森的共振价键(RVB)理论，弗里德曼博士将与丹·诺切拉教授合作，创造出成分纯的材料晶体，可用于制造高温超导体。这些晶体的合成将以在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反常X射线散射测量的结果为指导。弗里德曼博士将与ChemMat Cars的研究光束线科学家陈玉生博士合作。在她扩大参与的计划中，国际和平研究所将与材料科学与工程中心合作，开发与包括超导在内的能源问题有关的化学课程，供当地中学生使用，其中包括来自代表性不足群体的相当一部分学生。弗里德曼博士这样的研究最终旨在开发更高效的电导体--这是一个可以在电力分配等领域产生更高效率的技术领域。弗里德曼博士正在进行的扩大参与的努力，旨在鼓励各行各业的年轻人更好地了解科学，并有可能从事科学事业。
