This project will acquire a facility for state-of-the-art small/wide angle X-ray scattering (SAXS/WAXS) instrumentation for research, research training, and integrated research/education activities at the University at Buffalo (UB), The State University of New York (SUNY). The SAXS/WAXS instrument probesdifferences in electron density within a sample. Analysis of the data obtained provides structural details at length scales ranging from 0.2 to 100 nanometers. Examples of information to be obtained from SAXS/WAXS are (i) size and shape of polymers, proteins, and nanoparticles in solution, (ii) non-uniform (two-phase) structure of materials, and (iii) crystalline periodic structure of surfactants, polymers or nanocomposites. The SAXS/WAXS instrument will support high quality scientific research in nanostructured materials andrelated topics, which will result in important advances in the fundamental understanding of several methods of synthesis of nanoparticles and nanostructured materials and in the self-assembly of such nanoscopic building blocks.Broader impacts of the proposed work will be of two types: (a) societal impacts and improvements in quality of life due to long-term implementation of the science and technology developed in commercial applications; and (b) education and outreach impacts. In education and outreach, the proposed instrument will be used by numerous graduate students in their thesis research, as well as by undergraduate researchers. The instrument will also be used in formal science and engineering courses. Faculty involved in this proposal will continue their outreach efforts to underrepresented minority students at the high-school, undergraduate, and graduate levels. Finally, this facility will be made available to local industry, thus fostering intellectual connections between industry and academia and contributing to the localeconomy.

该项目将为最先进的小/广角X射线散射（SAXS/WAXS）仪器提供研究，研究，研究培训和综合研究/教育活动的仪器（UB），纽约州立大学（SUNY）（SUNY）。 样品中电子密度中的SAXS/WAXS仪器探针探测。 对所获得的数据的分析提供了范围为0.2至100纳米的长度尺度的结构细节。 从SAX/蜡获得的信息示例是（I）溶液中聚合物，蛋白质和纳米颗粒的大小和形状，（ii）材料的非均匀（两相）结构，以及（iii）表面活性剂，聚合物或纳米复合材料的晶体周期性结构。 SAXS/WAXS仪器将支持纳米结构材料中的高质量科学研究，这将在对几种合成纳米颗粒和纳米结构材料的合成方法的基本理解方面的重要进展，并在此类纳米企业的自我构建方面的自组成中的自我组成型，而质量的质量会影响两种类型的质量：在商业应用中开发的科学和技术； （b）教育和外展影响。 在教育和宣传方面，拟议的工具将在其论文研究中以及本科研究人员的论文研究中使用。 该乐器还将用于正规的科学和工程课程。 参与该提案的教师将继续他们在高中，本科和研究生级别的少数族裔学生的宣传工作。 最后，该设施将提供给当地工业，从而促进工业和学术界之间的智力联系，并为地方经济贡献。
