With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Villanova University will acquire a single-crystal/powder X-ray diffractometer. This instrument will facilitate studies in the following areas: a) optical and chemical properties of nanoparticles and their assembly; b) the synthesis, structural characterization, and reactivity of trans-spanning ligands on octahedral complexes; c) Organic Synthesis and Carbohydrate Chemistry; d) Chiral transition metal complexes for asymmetric catalysis; e) the structure of cytoplasmic fragments of TRPV1; and f) homogeneous Ziegler-Natta polymerization The X-ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and it provides accurate information about the spatial arrangement of the molecule relative to the neighboring molecules. These studies will have an impact in a number of areas, especially polymer synthesis and nanoscience.

在主要研究仪器（MRI）项目的支持下，维拉诺瓦大学化学系将获得一台单晶/粉末x射线衍射仪。该仪器将促进以下领域的研究：a)纳米粒子的光学和化学性质及其组装；B)八面体配合物上跨跨配体的合成、结构表征和反应性；c)有机合成与碳水化合物化学；d)不对称催化的手性过渡金属配合物；e) TRPV1细胞质片段的结构；x射线衍射仪可以精确测量分子的完整三维结构，包括键的距离和角度，并提供分子相对于邻近分子的空间排列的准确信息。这些研究将在许多领域产生影响，特别是聚合物合成和纳米科学。
