The definitive replacement of fossil fuels by solar fuels requires to improve the conversion efficiencies that are available today. Notably, inspirational natural photosynthesis is not very efficient in terms of solar energy conversion to fuels. Photosynthetic chromophores dissipate one fourth of the absorbed light via internal conversion (IC) followed by vibrational relaxation (VR) to the lowest energy excited states. IC and VR shape a decay cascade for the excited state population, that reaches…

Therapeutic options for Cystic Fibrosis (CF), the most common genetic metabolic disease in Europe, are insufficient. We propose a novel therapeutic strategy that obviates the need to overcome the human epithelial airway barrier by directly addressing the bacterial infections that cause respiratory failure and high CF patient mortality. Namely, an inhalable application of antisense oligomers (ASOs) targeting selectively the chronic microbial pulmonary CF lung infections. To create a basis for this new ASO-based CF therapy approach we will design and synthesize potent and type selective ASOs, define their physiological and resistance effects and further explore the targeted transport and release when formulated as modular systems.

The abrasion and fracture toughness of polymers can considerably be increased by adding hard nanoparticles such as silica. This is mainly caused by the development of localized shear bands, initiated by the stress concentrations stemming from the inhomogeneity of the composites. Other mechanisms responsible for toughening are debonding of the particles and void growth in the polymer matrix. Both phenomena strongly depend on the structure and chemistry of the polymers and shall be explored for branched networks (epoxy) and matrices of nestled fibres (cellulose, aramid).
The goal of the present project is to develop and apply dynamics simulation approaches to understanding polymer-nanoparticle and polymer-polymer interactions at i) the atomic scale and ii) at larger scales using coarse-graining.

The chemical environment can critically affect the fracture processes, leading to subcritical crack growth. The inner surfaces of the cracks are covered by adsorbates from the surrounding liquid or gas phase. When bonds break in the course of crack propagation, these adsorbates strongly react with the newly created surfaces, for example, by saturating the broken bonds. Examples are stress corrosion cracking in metals and semiconductors or the moisture-driven crack growth in silica. In both cases, the crack propagation induces and drives the incorporation of oxygen species, leading to an oxidation/hydroxylation of the inner surfaces, which completely alters the chemistry at the crack tip.
In this project we propose to study the complex interplay between bond breaking at the crack tip and the adsorption/bond saturation with molecules from the environment by MD simulations. The aim is to obtain mechanistic insights into environmentally-assisted fracture for model ceramic materials.

The mechanical properties and the fracture toughness of polymers can be increased by adding silica nanoparticles. This increase is mainly caused by the development of localized shear bands, initiated by the stress concentrations due to the silica particles. Other mechanisms responsible for the observed toughening are debonding of the particles and void growth in the matrix material. The particular mechanisms depend strongly on the structure and chemistry of the polymers and will be analysed for two classes of polymer-silica composites, with highly crosslinked thermosets or with biodegradable nestled fibres (cellulose, aramid) as matrix materials.
The aim of the project is to study the influence of different mesoscopic parameters, as particle volume fraction, on the macroscopic fracture properties of nanoparticle reinforced polymers.

Interface failure in both tension and shear is characterized by a dynamic interplay of local processes (breaking of bonds, interface contacts or – in case of frictional interfaces – asperities) and long-range elastic load re-distribution which may occur either quasi-statically or in a dynamic manner associated with wave propagation phenomena and can be mapped onto a network of partly break-able load transferring elements. This interplay may give rise to complex dynamics which are strongly influenced by contact geometry and also the chemical properties of the interface. A particularly simple case is the transition from static to sliding friction between continuous bodies where such dynamic collective phenomena are being discussed under the label of ‘detachment waves’.
The goal of P7 is to generalize this concept of ‘detachment waves’ to general problems of failure of frictional or adhesive joints, and to interfaces and bodies which possess a complex multi-scale chemical or geometrical structure, including hierarchical geometrical structures as encountered in biosystems.

A new research training group at FAU is being funded by the German Research Foundation. The research training group entitled „Synthetic Molecular Communications Across Different Scales: From Theory to Experiments“, or SyMoCADS for short, is led by Prof. Robert Schober (as spokesperson) and Prof. Kathrin Castiglione (Chair of Bioprocess Engineering) as co-spokesperson.
This structured training program addresses the highly interdisciplinary field of molecular communication. Molecules are used as information carriers to communicate with objects, cells or organisms in environments that are not suitable for traditional communication systems based on electromagnetic waves. Three different work clusters involving researchers from the Departments of Electrical Engineering, Chemical and Bioengineering, Mechanical Engineering, Chemistry and Pharmacy and Biochemistry as well as the University Hospital are investigating the sensing and control of bioprocesses on a microliter scale, the control of magnetic nanoparticles in blood vessels and molecular communication via volatile odorous objects.

Nanoparticles as carriers of pharmaceutical agents that can be released at specific times and in specific target areas in the sense of so-called “drug delivery” are of great interest to medicine. An important area of application is localized chemotherapy for tumor diseases, which prevents the entire body from being exposed to the therapeutic agent, thereby reducing otherwise harmful side effects. Due to their small size, individual nanoparticles have an advantage over larger drug carriers in the form of microparticles in that they can utilize the EPR effect (enhanced permeability and retention). This allows the drug to penetrate more deeply into tumor tissue and have a stronger effect on it. Our project focuses on “sonosensitive” nanostructures in which the active substances can be released by the action of ultrasound. Focusable ultrasound fields are required to limit this effect to specific tumor regions. Until now, the desired effect on sonosensitive nanoparticles of a suitable size has only been detectable at low ultrasound frequencies, which do not allow sufficient focusing. However, the applicants have recently succeeded in developing new sonosensitive nanoparticles (in the form of spheres and capsules) in which the effect also occurs at higher ultrasound frequencies with well-focused wave fields. The new nanoparticles are rehydrated, freeze-dried polylactic acid nanospheres in a water dispersion with a diameter of 120 nm, on which broadband noise is generated by sonication at 835 kHz, which is attributable to transient, drug-releasing cavitation. The planned project aims to optimize nanoparticle production with regard to efficient drug release. The mechanism of ultrasound-induced cavitation of such nanostructures will be elucidated. Microscopic methods (e.g., atomic force microscopy) will be used for the morphological characterization of the particles. For the functional characterization of the particles' effectiveness, an actuator-sensor system will be implemented that has a unit on the actuator side for generating focused power ultrasound, which allows the cavitation process to be optimized by varying relevant ultrasound parameters. On the sensor side, various ultrasonic methods for passive and active detection of cavitation will be implemented and tested. The sensor modalities are to be used in a suitable combination to optimize nanoparticle production and the operating mode for efficient, cavitation-based drug release. Based on the findings obtained in the project, concept proposals and system designs for medical applications are to be developed.

Chemical signals play a major role in physiological processes and are potent modulators of behaviour. The possible implication of chemosensory information in human social interaction, however, has long been neglected. Despite this, evidence is accumulating that an individual’s chemical signature bears not only information about genetically determined traits, but also about transient states such as the individual’s emotional or health status. The emerging field of human chemocommunication hence offers the intriguing possibility to make use of body odour signatures as an unobtrusive measure of internal states. The goal of this project is to develop tools for a new chemocommunication platform that is about to be established in a collaborative project of this consortium, including data scientists, psychologists, medical scientists, and chemists.

The aim of this project is to develop a transport system for the oral administration of mRNA vaccines that ensures the safe, stable, and efficient transfer of mRNA to the intestine through the use of acid-stable special lipids. Advantages include (1) a patient-friendly form of administration, (2) potentially better biodistribution and higher stability of the mRNA active ingredients, and (3) a simple and sustainable manufacturing process. This should make mRNA vaccinations simple, cost-efficient, and possible without major logistical effort, e.g., even in developing countries.
Lipid vesicles are particularly suitable for this purpose. Conventional lipid vesicles are unstable at the low pH value of the stomach. Membrane lipids of thermoacidophilic archaea contain aliphatic nonpolar chains that are linked to the polar head groups via ether bonds instead of ester bonds. In addition, some of the lipids are structured in such a way that they have polar head groups at both ends and span the entire membrane. In contrast to conventional cell membranes, they form a monolayer that is stable at high temperatures and low pH values. Due to their structure, archaeal lipids are also called tetraether lipids, and the vesicles formed from them are known as archaeosomes. In the planned project, the cultivation process of Archaeon Picrophilus oshimae as a starting material is to be optimized, standardized, and prepared for large-scale production.

Scanning probe microscopy allows quantitative measurements of structural, mechanical and electronic properties of molecular systems on metal surfaces. Using scanning tunneling microscopy, atoms and molecules can be manipulated in a controlled manner and their electronic density of states is measured. The forces needed to manipulate and deform individual molecules are often unknown. In this project area, the forces between individual molecules, as well as molecular switches on surfaces, are investigated …

Metal-organic charge-transfer complexes based on TCNQ shows exciting electrical or photochemical switching properties, which involves modification of the valence state of TCNQ (TCNQ-/TCNQ°). We use complementary microspectroscopic tools to investigate in-situ the switching behaviour of individual Ag-TCNQ nanocrystals. Structural probes like Nano-XRD and electron diffraction are considered to offer insight into potential structural modifications upon electrical switching.

M3d is a FP7 European project aiming at developing advanced magnetic materials suitable for designing a data storage solution in three dimensions (3D). Conventional planar (2D) devices are expected to reach the limits of scaling within less than a decade, so that long-term massive progress could only be achieved by exploiting the third dimension. We will develop the materials needed for such 3D memories based on magnetic shift-register devices, namely dense arrays of vertical magnetic wires in…
