Surface structures for localized electronic excitation and electrostimulation

Prof. Sylvia Speller, Universität Rostock
Department LL&M, Albert-Einstein-Str. 25, room 110
Zoom dial up:

Nature has brought about astounding performances in living and dead matter. Entangling micro- and nanostructures of both categories may represent a route to realize artificial tissues of hybrid systems, capable to meet current challenges in energy supply and health. To this end such entangled networks should to be broken down to elementary couplings and the respective structure and dynamics of individual units are to be studied. Surface structures can be prepared to fulfill functions such as optical stimulation or electric field hot spots. Localized excitation is a prerequisite to guide excitons through molecule aggregate cables and to develop alternatives to the rather energy consuming electronic circuitries. Localized optical and electric fields can also serve to provoke specific responses from live cells, i.e. to guide cells to places where they are needed. For realizing small micrometric and nanometric structures scanning probe microscopy methods are crucial. Challenges include targeted micro and nanostructuring, enhanced robustness in environments such as electrolytes, and proper docking of structures preserving functionality.

Sylvia Speller is Professor of Experimental Physics at the University of Rostock since 2012. Her research interests are understanding and controlling coupling processes on the nanoscale and the development of scanning probe microscopy methods for complex systems and environments. The PhD she received from the University of Osnabrück in 1995 with a dissertation on Scanning Tunneling Microscopy of atomic structures on metal surface systems. She spent postdoctoral stays at places such as Eindhoven and Leuven and worked as academic staff at the University of Osnabrück, where she completed her Habilitation in 2002. In 2001 she was appointed full professor for Experimental Physics at the Radboud University Nijmegen, where she coordinated research programs on Advanced Scanning Probe Microscopy and acted as director of NanoLab Nijmegen, a program dedicated to knowledge transfer between academia and industry in the field of nanoscience and technology. At the University of Rostock she is active in the department of Life, Light, and Matter (LLM) research of the interdisciplinary faculty (INF) and in the CRCs Electrically Active Implants and Light-Matter Interactions at Interfaces.

Modelling the spread of COVID-19:  Lessons learned

Prof. Verena Wolf, Saarland University, Saarland Informatics Campus
Zoom dial up:

Model-based forecasts of the possible course of the COVID 19 pandemic make an important contribution to deciding on effective interventions. The forecasts published in recent months were mostly only correct for very short periods, especially at the beginning of a wave and the number of cases was often over- or underestimated by a factor of about two to sometimes six or more. The effects of measures such as contact and travel restrictions could only be inadequately predicted by model forecasts.
In this talk, I will discuss the strengths and weaknesses of commonly used models of the spread of viral infections and explain what insights model-based forecasts provide us. They can (and should) be used to justify policy decisions only to a limited extent - be it relaxations or even restrictions.

Towards a sustainable future: Plasma-based CO2, CH4 and N2 conversion into value-added compounds or renewable fuels

Prof. Annemie Bogaerts, Research group PLASMANT, University of Antwerp, Belgium

Plasma technology is gaining increasing interest for various gas conversion applications, such as CO2 and CH4 conversion into value-added compounds, and N2 fixation for fertilizer applications [1-4].
Gas discharge plasma is a (partially) ionized gas, created by applying electricity. It consists of electrons, various ions, radicals, excited species, besides neutral gas molecules. The electrons are mainly heated by the applied electric field, due to their small mass, and they activate the gas molecules by electron impact ionization, excitation and dissociation, creating new ions, excited species and radicals. These are very reactive, so they can easily produce new products. Hence, thermodynamically or kinetically limited reactions can proceed at mild conditions of gas temperature and pressure, because the gas activation is accomplished by the electrons. Typically, gas discharge plasma reactors operate at atmospheric pressure and the gas is introduced at room temperature. Plasma technology has low CAPEX costs. Finally, the plasma reactors can quickly be switched on/off, and because they operate with electricity, they are very suitable to be combined with (fluctuating) renewable electricity, for electrification of chemical reactions.

To improve these applications in terms of conversion, energy efficiency and product formation, a good insight in the underlying mechanisms is desirable. We try to obtain this by computer modelling and experiments.

I will first give a brief explanation about different types of plasma reactors used for gas conversion. That will be followed by an overview of the state-of-the-art in plasma-based CO2 and CH4 conversion and N2 fixation, with these different types of plasma reactors, briefly discussing the opportunities and main challenges. Subsequently, I will present some recent results obtained in our group PLASMANT in this domain, including experiments to improve the performance, and modeling for a better understanding of the underlying mechanisms.

Microstructure-informed in silico modeling of the human brain

Dr.-Ing. Silvia Budday, Lehrstuhl für Technische Mechanik, Friedrich-Alexander-Universität Erlangen

Brain tissue is not only one of the most important but also the arguably most complex and compliant tissue in the human body. While long underestimated, increasing evidence confirms that mechanics plays a critical role in modulating brain function and dysfunction. Computational models based on nonlinear continuum mechanics can help understand the basic processes in the brain, e.g., during development, injury, and disease, and facilitate early diagnosis and treatment of neurological disorders.
By closely integrating biomechanical experiments on human brain tissue, microstructural analyses, continuum mechanics modeling, and finite element simulations, we develop computational models that capture both biological processes on the cellular scale and macroscopic loading and pathologies. We introduce the cell density as an additional field controlling the local tissue stiffness and brain growth during development. We demonstrate that our models are capable of capturing the evolution of cell density and cortical folding in the developing brain as well as regional variations in tissue properties in the adult brain. In the future, those models can provide deeper insights into the behavior of the human brain under physiological and pathological conditions and simulate progression of injury and disease.

Silvia Budday, currently an Independent Research Group Leader at the Institute of Applied Mechanics, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Germany, studied Mechanical Engineering at the Karlsruhe Institute of Technology (KIT) with a one-year stay at Purdue University, Indiana, USA, and graduated with the best Master’s degree of a female student in 2013.

CO2 activation with light - is it possible?

Prof. Stefanie Tschierlei, Physical Chemistry, TU Braunschweig

Due to the excessive use of carbon-based raw materials for energy production, the greenhouse effect is inexorably increasing. The reduction of CO2, one of the most common anthropogenic greenhouse gases, into more synthetically usable C1 building blocks is therefore highly desirable. A sustainable method for conversion is photocatalysis with suitable photoactive substances. Such a system was developed as early as 1983 by Lehn et al. based on (bpy)Re(CO) 3 Cl (bpy = 2,2'-bipyridine).
We recently discovered an unexpected wavelength dependency of this well-known[2] (bpy)Re(CO)3Cl complex. Irradiation with wavelengths >450 nm triggers an alternative reaction pathway involving a dimeric Re-Re species and results in an increased catalytic activity during the photocatalytic CO2 reduction. Inspired by these results we designed a dinuclear rhenium complex with closely oriented metal centers. The presented study aims on the elucidation of possible reaction mechanism. Therefore, time-dependent catalytic and spectroscopic experiments as well as UV/vis and IR spectroelectrochemical measurements accompanied by TD-DFT calculations were performed.

Stefanie Tschierlei is a full professor (W3) at the Institute for Physical and Theoretical Chemistry and head of the Department of Energy Conversion at the TU Braunschweig. ST studied chemistry at the Friedrich-Schiller-Universität in Jena from 2002 to 2006. After finishing her dissertation in 2010 with summa cum laude she received a DAAD scholarship for a postdoc stay at the Department of Photochemistry and Molecular Science at the Uppsala University in Sweden. She then worked as a researcher at various universities, including Rostock, Stuttgart and Ulm before she was appointed as a professor in August 2020. Since 2022 she is the chairwoman of the GDCh division of photochemistry. Her research is mainly engaged in the spectroscopic and mechanistic study of light-driven processes for (solar) energy conversion, e.g. the splitting of water or the reduction of CO2.

Cellular response to wear and corrosion products
Dr. Anika Jonitz-Heincke, Leiterin Geweberegeneration, Orthopädische Klinik und Poliklinik, Universitätsmedizin Rostock

Ein umfassendes Verständnis der Abrieb-induzierten Osteolyse ist die Voraussetzung, um neue präventive bzw. therapeutische Ansätze zu entwickeln, die das Fortschreiten der Osteolysen und die damit verbundene Implantatlockerung verzögern oder verhindern können. In diesem Zusammenhang ermöglichen Toxizitätsanalysen auf zellulärer Ebene die Identifikation der spezifischen biologischen Antwort auf Abrieb- und Korrosionsprodukte. Als entscheidender Zelltyp in Hinblick auf das Entzündungsgeschehen und den Knochenabbau werden Makrophagen genannt, da diese Zellen in der Lage sind, Verschleißprodukte zu phagozytieren und als Antwort Entzündungsmediatoren freisetzen. Im Gegensatz dazu wird in wenigen Arbeiten darauf hingewiesen, dass neben Makrophagen auch Osteoblasten und Fibroblasten in der Lage sind, Abriebpartikel zu phagozytieren. Um eine umfassende Zellantwort auf Verschleißprodukte zu erhalten müssen daher verschiedene Zelltypen betrachtet werden, um weiterführend methodische Perspektiven für die Risikobewertung bewährter und neuartiger Implantatmaterialien aufzuzeigen.

AJH ist seit 2009 wissenschaftliche Mitarbeiterin im Forschungslabor für Biomechanik und Implantattechnologie der Orthopädischen Klinik. Seit 2012 leitet sie die Arbeitsgruppe Geweberegeneration und im Jahr 2016 hat sie die Position als stellvertretende Laborleiterin übernommen. Sowohl ihre Promotion in 2014 und ihre Habilitation in 2022 absolvierte sie im Fachgebiet der Experimentellen Orthopädie. Ihre Forschungsinhalte umfassen verschiedene Aspekte der muskuloskelettalen Geweberegeneration, insbesondere der biophysikalischen Stimulation von Knochen- und Knorpelgewebe, die Zell-Material-Interaktion sowie biotribologische Fragestellungen.

Zellphysiologie und Geweberegenration – Plasmaphysik in der BioMedizin

Prof. Dr. Barbara Nebe, Arbeitsbereich Zellbiologie, Universitätsmedizin Rostock

Plasma medicine and plasma biology has become an important area of interdisciplinary research in plasma physics, combining biology, chemistry and physics. The fields of application of physical plasma in biomedicine are increasing and include the direct influence of physical plasma on cells and tissues or the biomaterial surface functionalization. Biomaterials should be bioactive in stimulating the surrounding tissue to accelerate the ingrowth of permanent implants. Plasma-chemical modifications are able to boost not only cell attachment, cell migration and differentiation, but also intracellular signaling.

J. Barbara Nebe is an adjunct Professor of Cell Biology, and chair of the Department of Cell Biology in the Rostock University Medical Center. BN received her Ph.D. in 1995, and the Habilitation and venia legendi in 2005 with the theme “Integrin receptors, cell adhesion, and cell signalling – clinical aspects”. She is focused on cell biological issues in interfacial interactions of the biosystem to implant surfaces, and the impact of physical factors on cell physiology. She is experienced in cross-disciplinary research and project leader of several DFG projects. BN was invited speaker, e.g. in Paris (THERMEC), Ambleteuse (BIOMAT), Shanghai (BIT's RMSC), Las Vegas (THERMEC), Singapore (ICMAT). She organised/co-organised 10 international congresses, e.g. ’Functionalised Bio Materials: Therapeutic Applications’ for the European Material Research Society.
