With support from the Chemistry Research Instrumentation and Facilities - Multiuser Instrument Acquisition (CRIF-MU) Program, the Department of Chemistry at the University of Iowa will purchase a scanning probe microscope (SPM) with the following capabilities: atomic force and scanning tunneling microscopy (AFM and STM); magnetic force microscopy; electrochemistry capabilities; liquid attachment for controlled environments; optical microscope attachment; patterning/molecular attachment; glove box attachment; temperature control; and quantitative AFM phase imaging. The SPM will enable the following projects: a) the synthesis of bottlebrush polymers; b) assembly of monolayers on silicon and their applications in nanotechnology; c) in situ studies of surface reactions of atmospheric and environmental relevance; d) studies of hierarchical structures of nanocrystalline zeolites; e) characterization of nanoelectrode structures; and f) investigation of cellular function at single cells.The scanning probe microscope (SPM) enables researchers to image atoms directly. The interdisciplinary studies that will be carried out using this instrument will have an impact in materials sciences, nanotechnology and environmental chemistry. In addition, a significant number of graduate and undergraduate students will gain hands-on experience with this state-of-the-art instrumentation since it will be used in both a laboratory course and in research. Finally, external users from regional universities and colleges will have access through a weekend program.

在化学研究仪器和设施-多用户仪器采购（CRIF-MU）计划的支持下，爱荷华州大学化学系将购买具有以下功能的扫描探针显微镜（SPM）：原子力和扫描隧道显微镜（AFM和STM）;磁力显微镜;电化学能力;受控环境的液体附件;光学显微镜附件;图案化/分子附着;手套箱附着;温度控制;和定量AFM相位成像。 SPM将促成以下项目：a）瓶刷聚合物的合成; B）硅上单分子膜的组装及其在纳米技术中的应用; c）与大气和环境相关的表面反应的现场研究; d）纳米晶体沸石的分级结构研究; e）纳米电极结构的表征; f）研究单个细胞的细胞功能。扫描探针显微镜（SPM）使研究人员能够直接对原子进行成像。使用该仪器进行的跨学科研究将对材料科学、纳米技术和环境化学产生影响。 此外，大量的研究生和本科生将获得这种最先进的仪器的实践经验，因为它将用于实验室课程和研究。 最后，来自地区大学和学院的外部用户将通过周末计划访问。
