0820921ScalFunds from this Major Research Instrumentation (MRI) Program grant will support acquisition of an energy dispersive spectroscopy X-ray microanalysis (EDS) unit to be interfaced with an existing scanning electron microscope system at CUNY. Funds are also requested for a carbon evaporator system which facilitates conductive sample coating. The system will be employed to 1) characterize unknown materials in sedimentary rocks using coupled elemental analysis to infer tectonic history; 2) to understand abrasion patterns, grain zonation and straigraphic mineral chemistry in troumalines, zircon and garnets; 3) to better understand pearl microstructure; to visualize nanostructured polyaniline-enzyme-metal particles used in highly specific biosensors; 4) to visualize polysiloxane networks used to stabilize gold, platinum and palladium nanoparticles; 5) to assess the activity, selectivity, and efficiency of nano-scale metal particle catalysts; and 6) to determine the ratio of metal to siloxane in Pd-colloids. The instrument will be housed in the Chemistry Department and jointly administered by the PIs. Broader impacts will be evident through a commitment to provide undergraduates with a strong foundation in science. CUNY-QCC has STEP and College Now programs to allure students at the critical age between high school and college. The College attracts students from a broad swath of ethnic backgrounds and advantages. The acquisition will be incorporated into the state?s ?Decade of Science,? and provide a resource for several departments.

该主要研究仪器（MRI）计划赠款的0820921Scalfunds将支持获得能量分散光谱X射线微分析（EDS）单元（EDS）单元，该单元与CUNY的现有扫描电子显微镜系统相连。还要求资金使用碳蒸发器系统，以促进导电样品涂料。该系统将用于1）使用耦合元素分析来推断构造历史的沉积岩石中未知材料的表征； 2）了解毛毛，锆石和石榴石中的磨损模式，谷物分层和横幅矿物化学； 3）更好地了解珍珠微观结构；可视化在高度特异性生物传感器中使用的纳米结构聚苯胺 - 酶 - 金属颗粒； 4）可视化用于稳定金，铂和钯纳米颗粒的多硅氧烷网络； 5）评估纳米级金属颗粒催化剂的活性，选择性和效率； 6）确定金属与硅氧烷在Pd-colloid中的比率。该仪器将安置在化学部门，并由PIS共同管理。通过为大学生在科学领域提供强大的基础的承诺，将显而易见地影响更广泛的影响。 CUNY-QCC现在有一步和大学计划在高中和大学之间的关键年龄上吸引学生。该学院吸引了许多种族背景和优势的学生。收购将被纳入州科学十年中？并为多个部门提供资源。
