With this award from the Major Research Instrumentation (MRI) Program, the Department of Physics at North Carolina A&T University will acquire a multi-source reflectron time-of-flight mass spectrometer. This equipment will enhance research in a number of areas including a) the synthesis, structure and properties of metal-containing nanoclusters; b) millimeter-wave spectroscopy of mass-selected molecular ions and cluster ions; c) the synthesis, isolation and characterization of melanogenic substrates and cofactors using mass determination; and d) development of electrochemical techniques in the decontamination of organic contaminants, especially pesticides. Mass spectrometry (MS) is a technique used to probe intimate structural details and to obtain the molecular compositions of a vast array of organic, bioorganic, and organometallic molecules. The results from these studies will have an impact in a number of areas including environmental chemistry and nanosciences.

有了这项来自主要研究仪器（MRI）计划的奖项，北卡罗来纳州AT大学物理系将获得一台多源反射飞行时间质谱仪。这一设备将加强若干领域的研究，包括：a）含金属纳米团簇的合成、结构和性质; B）质量选择分子离子和团簇离子的毫米波光谱学; c）使用质量测定法合成、分离和表征黑素生成基质和辅助因子; d）开发有机污染物特别是农药去污的电化学技术。质谱（MS）是一种用于探测紧密结构细节并获得大量有机、生物有机和有机金属分子的分子组成的技术。这些研究的结果将对包括环境化学和纳米科学在内的许多领域产生影响。
