With this award from the Major Research Instrumentation (MRI) and Chemistry Research Infrastructure and Facilities programs, Professor YuHuang Wang from the University of Maryland College Park and colleagues Janice Reutt-Robey, Lawrence Sita, Chunsheng Wang and Liangbing Hu have acquired an atomic force microscope system. In an AFM a laser beam is directed to a surface by means of a cantilever and tip. As the cantilever is displaced by interacting with the surface, a reflection of the laser beam is displayed on a detector (photodiode). In this way an image of the surface can be created with the aid of an electronic system. In general, an AFM has three major abilities: force measurement, imaging, and manipulation. The microscope is an important tool in the investigation of the surfaces of materials. It is used in fundamental and applied research to study morphology of surfaces, surface imaging and functionalization, electrical, magnetic, chemical and mechanical properties of surfaces. This knowledge enables advances in developing better materials in fields such as nanoscience and energy science. The instrument is used in the research and training of undergraduate and graduate students preparing them for technical careers and opportunities for advanced education. The proposal is aimed at enhancing research and education at all levels, especially in: (a) studying nanoparticle transport and internalization at model interfaces, (b) probing quantum defects in low-dimensional carbon materials, (c) mapping peak current and peak force of carbon nanoparticles in covetics, (d) imaging small circuits on glass, (e) studying living polymerization and direct assembly of precision polyolefins, (f) assessing the integrity and stability of xeolite membranes, (g) understanding and tailoring designing of solid state interphases for nanostructured silicon electrodes and (h) studying solid electrode interface formation, structure and evolution of molybdenum disulfide.

马里兰大学帕克分校的 YuHuang Wang 教授及其同事 Janice Reutt-Robey、Lawrence Sita、Chunsheng Wang 和 Liangbing Hu 获得了重大研究仪器 (MRI) 和化学研究基础设施项目的奖项，获得了一台原子力显微镜系统。在 AFM 中，激光束通过悬臂和尖端引导至表面。当悬臂通过与表面相互作用而发生位移时，激光束的反射会显示在探测器（光电二极管）上。通过这种方式，可以借助电子系统创建表面图像。一般来说，AFM 具有三个主要功能：力测量、成像和操纵。显微镜是研究材料表面的重要工具。它用于基础和应用研究，研究表面形态、表面成像和功能化、表面的电、磁、化学和机械性能。这些知识有助于在纳米科学和能源科学等领域开发更好的材料。该仪器用于本科生和研究生的研究和培训，为他们的技术职业生涯和接受高等教育的机会做好准备。 该提案旨在加强各个层面的研究和教育，特别是在：（a）研究模型界面处的纳米颗粒输运和内化，（b）探测低维碳材料中的量子缺陷，（c）绘制峰值电流和峰值力Covetics 中的碳纳米颗粒，(d) 对玻璃上的小电路进行成像，(e) 研究精密聚烯烃的活性聚合和直接组装，(f) 评估 xeolite 膜的完整性和稳定性，(g) 理解和定制固态设计间期为纳米结构硅电极以及（h）研究二硫化钼的固体电极界面形成、结构和演化。
