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.

X射线衍射分析对于直接和明确地确定材料的分子和晶体结构至关重要。如今，晶体结构研究被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），固态物理学，矿物学，材料和法医学以及药理学。本项目正在获得X射线衍射X8 APEX系统（Bruker AXS Inc.，USA）和结晶系统，用于直接在衍射仪上生长单晶。这种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。 X8 APEX系统是一款汇集了布鲁克和诺尼厄斯全球开发的最佳功能的产品：最灵敏的APEX CCD探测器（布鲁克）、最精确但灵活的Kappa测角仪（诺尼厄斯）以及最先进的软件。该系统的显着特点是高速数据收集、区域检测器的灵敏度（允许处理非常小且弱衍射的样品）、由于低温系统而有机会处理不稳定和低熔点的样品以及应用的简单性。 他们正在研究几类物体的结构-性能关系，如非线性和电光材料，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。我们正在通过收购新的仪器来更新我们的X衍射仪器，这些仪器可以促进易用性、快速数据采集、灵敏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，以及不稳定和低熔点的样品。 这将使我们能够确定几类物体的结构-性能关系，如非线性和电光材料，推进剂，矿物质和生物活性化合物。
