MRI: Acquisition of New Single Crystal X-Ray Diffraction System for Teaching/Research Laboratory

x射线衍射分析对于直接和明确地测定材料的分子和晶体结构是必不可少的。如今，晶体结构研究被应用于许多科学和技术领域：分析、有机、无机和有机金属化学、生物化学（特别是蛋白质晶体学）、固态物理、矿物学、材料和法医学以及药理学。目前的项目是获得x射线衍射X8APEX系统（美国Bruker AXS公司）和结晶系统，用于直接在衍射仪上生长单晶。该仪器将使我们能够创建一个现代化的教学分析和结构研究。X8APEX系统是一款汇集了全球布鲁克和诺纽斯开发的最佳功能的产品：最灵敏的APEX CCD探测器（布鲁克），最精确但最灵活的Kappa goniostat（诺纽斯），以及最先进的软件。该系统的显著特点是高速数据采集，区域探测器的灵敏度（允许使用非常小和弱衍射的样品），由于低温系统，有机会使用不稳定和低熔化的样品，并且应用简单。他们正在研究几类物体的结构-性质关系，如非线性和光电材料、推进剂、矿物和生物活性化合物。x射线衍射分析用于确定材料的结构。这些研究被用于许多科学和技术领域：化学、生物化学、物理、矿物学、材料和法医学以及药理学。我们正在更新我们的x衍射仪器，通过收购新的仪器，促进易用性，快速数据采集，敏感的检测系统和最先进的软件。这些能力将使我们能够处理通常难以研究的材料，包括小而弱衍射的样品，以及不稳定和低熔化的样品。这将使我们能够确定几类物体的结构-性质关系，如非线性和光电材料、推进剂、矿物和生物活性化合物。

X-Ray diffraction analysis is essential for the direct and unambiguous determination of the molecular and crystal structure of materials. Nowadays, crystal structure investigations are used in numerous areas of science and technology: analytical, organic, inorganic and organometallic chemistry, biochemistry (in particular, in protein crystallography), solid-state physics, mineralogy, materials and forensic science, and pharmacology. The present project is acquiring an X-ray diffraction X8APEX system (Bruker AXS Inc., USA) and Crystallization System for single crystal growth directly on a diffractometer. This instrumentation will allow us to create a modern teaching analytical and structural research. The X8APEX system is a product that collected the best features of worldwide Bruker and Nonius development: the most sensitive APEX CCD detector (Bruker), the most precise yet flexible Kappa goniostat (Nonius), and state-of-the-art software. Notable features of this system are high speed data collection, sensitivity of the area detector (which allows work with very small and weakly diffracting samples), the opportunity to work with unstable and low melting samples due to low temperature system, and simplicity of application. They are studying structure-property relations in several classes of objects such as nonlinear and electro-optical materials, propellants, minerals and bioactive compounds. X-Ray diffraction analysis is used to determine the structure of materials. These investigations are used in numerous areas of science and technology: chemistry, biochemistry physics, mineralogy, materials and forensic science, and pharmacology. We are updating our x-dffraction instrumentation through the acquisition of newer instrumentation that fosters ease of use, rapid data acquisition, sensitive detection systems and state-of-the-art software. These capabilities will let us work with materials which are often difficult to study, including small and weakly diffracting samples, as well as unstable and low melting samples. This will allow us to determine structure-property relations in several classes of objects such as nonlinear and electro-optical materials, propellants, minerals and bioactive compounds.
