The research work in the first applicant's working group focuses on interfacial chemistry aspects of adhesion, corrosion and nanobiomaterials. In all these areas, the dynamics of submicroscopic structures at electrolyte/solid interfaces is of outstanding importance. Until now, relevant processes such as molecular adsorption, desorption, self-organisation or corrosion could not be analysed in real time. The proposed high-speed atomic force microscope (HS-AFM) is now intended to close precisely this methodological gap. It will enable to follow the dynamics of surfaces and interfaces in the nanometer range with a temporal resolution in the range of seconds. In particular, the device should make it possible to investigate not only model surfaces but also complex materials and coatings under relevant environmental conditions (e.g. under mechanical load and control of the electrode potential). Cooperating research groups in the department of chemistry at Paderborn University consider research topics of energy storage and conversion, as well as coating and process technology. In these areas, too, high-speed atomic force microscopy allows new insights into the correlation of structure, dynamics and functional properties of materials. The application for the HS-AFM also significantly supports the activities of the central scientific facility "Institute for Lightweight Design with Hybrid Systems". Here, the focus of the application is on the analysis of alloy and polymer surfaces as well as composite materials under corrosive conditions or mechanical load. The research in the second applicant's working group focuses on the large-scale generation of functional nanostructures using self-organization methods. The focus is on the fundamental understanding of dynamic processes that allow the targeted generation of periodic nanopatterns on large surfaces, which can be used in a wide range of applications. These include advanced micro- and optoelectronics, plasmonics, sensor technology, energy, medicine and environmental technology. Depending on the type of structure to be fabricated and the required structure size of typically 10 - 1000 nm, block copolymer lithography and/or nanosphere lithography are combined with thin film deposition methods or, more recently, 2D material transfer. The achieved structure sizes make it necessary to investigate the surface morphologies with atomic force microscopes and to analyze the internal structure by means of modern transmission electron microscopy. For the latter, the working group operates state-of-the-art analytical high-resolution TEM, which is made available to neighboring groups in the faculty and at other universities in collaborations.

第一申请人工作组的研究工作重点介绍粘附，腐蚀和纳米生物材料的界面化学方面。在所有这些领域，电解质/固体接口处的亚镜结构的动态非常重要。到目前为止，无法实时分析相关过程，例如分子吸附，解吸，自组织或腐蚀。拟议的高速原子力显微镜（HS-AFM）现在旨在精确缩小这种方法上的差距。它将能够遵循纳米范围内的表面和接口的动力学，并在秒范围内具有时间分辨率。特别是，该设备不仅可以研究模型表面，而且还可以在相关环境条件下（例如在机械负载和电极电位的控制下）进行复杂的材料和涂层。帕德伯恩大学化学系的研究小组考虑了能源存储和转换的研究主题，以及涂料和处理技术。在这些区域，高速原子力显微镜也可以使材料的结构，动力学和功能特性相关的新见解。 HS-AFM的申请还大大支持了中央科学设施“与混合系统轻量级设计研究所”的活动。在这里，应用的重点是在腐蚀条件或机械载荷下的合金和聚合物表面以及复合材料的分析。第二个申请人工作组的研究重点是使用自组织方法的大规模生成功能纳米结构。重点是对动态过程的基本理解，该过程允许在大型表面上有针对性地生成周期性的纳米模式，这些表面可用于广泛的应用。其中包括高级微型和光电学，血浆技术，传感器技术，能量，医学和环境技术。取决于要制造的结构类型，所需的结构大小通常为10-1000 nm，块共聚物光刻和/或纳米层光刻与薄膜沉积方法或最近的2D材料转移相结合。实现的结构大小使得有必要使用原子力显微镜研究表面形态，并通过现代透射电子显微镜分析内部结构。对于后者，工作组运营着最先进的分析高分辨率TEM，该TEM可供教职员工和其他大学合作的邻近群体提供。
