Interface Chemistry and Polymer Science (UL)*

The Abel group at the University of Leipzig (Wilhelm-Ostwald-Institute of Physical and Theoretical Chemistry and Institute of Chemical Technology) is engaged in research in the field of molecular physical chemistry, smart material science, analytical science, ultrafast spectroscopy, and nanoscale imaging related to surfaces and surface modification/engineering. Our activities have the purpose of obtaining fundamental knowledge of matter and material to develop new molecular and analytical probes, new interface materials, and finally to use the knowledge to develop advanced analytical techniques, smart materials and material coatings, and ultimately devices and high-tech material surfaces (soft matter, adaptive, smart, switchable, responsive, etc.) for industry and industrial applications.

 

Abel Group@IOM: Research Department  Sensoric Surfaces and Functional Interfaces

The research area 5 at the Leibniz Institute of Surface Engineering (IOM) deals with the research and development of sensoric, responsive and functional (active) interfaces of matter in current and future fields of application and action. Fundamental mechanistic details are examined and, if possible, implemented in innovative technological applications in the field of sensors and energy conversion. Research area 5 is very well networked internally and externally (both nationally and internationally) and, with its cooperation partners from research (universities and research institutes) and industry, works on the following main research topics, which address the central socio-technical challenges of our time : 

(i) Integrated diamond-based technologies 

(ii) Switchable and responsive surfaces 

(iii) Electron and photon modified material surfaces for sensory applications 

(iv) Functional interfaces and technologies for energy conversion 

(v) Development and applications of novel particle sensors  

The topics (i) - (v) and thus the fields of action of research area 5 are aimed at important current and future social and technological challenges. On the one hand, diamond sensors and integrated diamond-based technologies are being developed. On the other hand, the principle of the resistive switch (memristor), which is known from solid-state research, is to be transferred to the level of individual molecules for the first time and individually functionalized molecular metal oxide complexes are to be investigated as quasi “single-molecule memories”. In the Hertz electron beam laboratory, the non-thermal modification of material surfaces and their characterization for sensory applications (force, fields, current, temperature, etc.) are advanced. Finally, functional interfaces, such as those in fuel cells, also play an important role as integrated surfaces (interfaces) for energy conversion (for more information visit www.iom-leipzig.de).
