U.S.-U.K. Cooperative Research: Universality of Defects in Layered Materials

9904127 Winey这个为期三年的奖项支持美国和英国在材料科学方面的合作研究，由宾夕法尼亚大学的Karen Winey和英国谢菲尔德大学的Anthony J. Ryan共同完成。 该研究探讨了一系列柔软分层材料中缺陷的产生和松弛。 特别是，它解决了一个明显缺乏普遍性的问题，即嵌段共聚物（具有短弛豫时间的层状材料）形成焦锥缺陷。美国研究人员为这次合作带来了使用电子显微镜成像和缺陷的专业知识。 英国研究人员利用同步加速器光源对材料进行原位表征的专业知识对此进行了补充。 该合作提供了由英国研究小组开发的独特模型二嵌段共聚物的使用权，并提供了世界级同步加速器源-英国的达雷斯伯里设施和法国格勒诺布尔的欧洲同步加速器研究设施。

9904127WineyThis three-year award supports US-UK collaborative research in materials science between Karen Winey at the University of Pennsylvania and Anthony J. Ryan of the University of Sheffield in the United Kingdom. The research explores the creation and relaxation of defects in a series of soft, layered materials. In particular, it addresses an apparent lack of universality, namely that block copolymers (layered materials having short relaxation times) form focal conic defects.The US researcher brings to this collaboration expertise in imaging and defects using electron microscopy. This is complemented by the British researcher's expertise of in-situ characterization of materials using synchrotron sources. The collaboration provides access to unique model diblock copolymers developed by the British research group and access to world class synchrotron sources - the Daresbury facility in the United Kingdom and the European Synchrotron Research Facility in Grenoble, France.
