Projekt: Fabrication of customisable graphene sensors for biomedical applications

Dr. Nishar Hameed

It is estimated that current biosensor materials would need to be significantly more efficient to be suitable for accurate early stage diagnosis of irreversibly progressive neurodegenerative health conditions. Novel sensor designs using graphene offer feasible solutions to construct extremely sensitive and rapidly responsive materials to exceed the required performance. Driven by our recent developments in hybrid material design, process control and sensor fabrication, with this collaborative grant we shall further establish experimental verification of designs of customisable graphene sensors with high accuracy for biomedical applications.

Projekt: Synthesis and Characterization of Iridium-Decorated Titanium Oxynitride Supported on Nanocarbon    (Ir/TiONx@NCF) for Water splitting

Dr Aruna Kunhiraman Kalasapurayil

Hydrogen is regarded as the future fuel and currently with a global production of 70 million ton/year. PEMWE which has the ability for fast load change, high power and energy efficiency, and high gas purity uses expensive catalyst at the anode (OER) and the cathode (HER) side. Cathode requires ca. 0.5 – 1 mg Pt/cm2 and anode requires 2 mg Ir/cm2. However, the scarcity and high cost of this precious metal are challenges for sustainable development of PEMWEs. The areas on which research can be more focused are: (1) enhanced intrinsic activity of the catalysts by material design and (2) advanced electrode morphologies and cell configurations. The OER is more challenging and sluggish kinetics in water splitting, where the complex four electron process that produces protons and oxygen requires high overpotential. Iridium used for OER are either metallic Ir nanoparticles or IrO2. But during OER, it gets oxidized to amorphous IrOx. Ir with 3+ oxidation state was found to be more active compared.

Projekt: Responsibility and Impact of Multinational Food Corporations on Public Health Nutrition in Ghana

Dr. Eric Nyarko

The responsibility and impact of multinational food corporations in emerging economies, particularly on the nutrition transition, has long been an important public health issue. The extent to which food corporations consider public health and nutrition issues in emerging economies as part of their corporate social responsibility initiatives and their potential impact is a neglected area of research. This interdisciplinary research aims to assess how food corporations understand and implement their role and responsibility for food, nutrition, and health in developing countries, using Ghana as an example, and will develop a conceptual model that identifies different impact areas. The study will further demonstrate and critically assess the impact of food, health, and nutrition-related corporate social responsibility measures on public health nutrition in Ghana using experimental designs and to derive concrete action measures for business, public health nutrition policy and society.

Projekt: Climatic forcing of global ecosystem changes from the Last Glacial Maximum to the end of the 21st century

Dr. Alejandro Ordonez

Safeguarding biodiversity during the Anthropocene requires robust forecasts of how climatic changes will change ecosystems. The proposed project will address this by developing new metrics of ecosystem change: velocity vectors of phytoclimatic change. Phytoclimates express the climate’s suitability for plant growth forms (e.g. evergreen tree, grass) that characterize ecosystems. The new phytoclimatic velocity vectors represent how fast growth forms would have to migrate to assemble the same ecosystem elsewhere in a future climate. We will build the new metrics by combining modelling work done by the host for transforming climates into phytoclimates and the statistical tools developed by the applicant for computing (phyto-)climatic velocity and its components driving ecosystem disaggregation and reassembly. Using existing climate simulations, we will compute phytoclimate velocity metrics during the late Pleistocene climate transition and the end of the 21st century.

Dr Jan Blahůt
Researcher at the Academy of Sciences, Institute of Rock Structure and Mechanics, Prague, Czech Republic

Climate change will affect temperature and moisture regimes in mid-latitude regions such as Bavaria and Czechia. Previous studies suggest that warmer and wetter climates will accelerate rock weathering. This should affect the current rockfall hazard as it was already observed. However, there is a lack of data that directly quantifies the influence of temperature and climate change-induced temperature change on rock strength. This short-term project aims to answer the important question: How much will change in moisture and temperature amplify the rock weathering? A series of controlled temperature loadings will be performed on selected rock samples from a mild climate of Central Czechia under dry and saturated conditions. During the loading, automatic ERT, TDR and AE sensors will be used to monitor moisture and cracking of the samples. This will be followed by sample testing to analyse changes in the rock strength.

Project Title: Sustainability,  Climate Risk and Sovereign Credit Ratings

This study will examine climate risk exposures, environmental awareness and attitudes toward climate risk at the country level. These factors have not been widely explored in previous studies on sovereign credit risk. In the first stage (to be conducted in 2022), we will address two questions: (i) How did exposures to climate risk affect a country’s sovereign rating level and rating change?; and (ii) Was there a structural change in sovereign rating criteria toward more stringent ratings following the signing of the Paris Agreement? In the second stage (to be carried out in 2023+), we will examine the effect of environmental awareness on sovereign rating dynamics, and answer this question: Did environmental awareness and attitude toward climate risk in a country moderate the effects of climate risk exposures on its rating level and rating change? This study should contribute to the debates concerning the regulations on climate change and environmental risk mitigation across countries.

Project Title: Improving self-monitoring feedback on eating behavior

Dietary self-monitoring is a key predictor of success in behvioral weight loss programs. To support greater adherence to self-monitoring and to help individuals interpret their own self-monitoring data to set effective behavioral goals, participants are typically provided with interventionist feedback. Currently, there exists little empirical evidence, however, regarding how dietary self-monitoring feedback should be constructed, how participants interpret feedback, and what impact feedback makes on future eating behaviors. Examining perceptions of various forms of dietary self-monitoring feedback (e.g., graphical vs. written vs. oral feedback) as well as the effect of feedback on future eating behaviors would provide necessary insight to inform future research on the optimal design for self-monitoring feedback.

Project Title: Discrediting Vision: Music and Optical Illusion in Nineteenth-Century Europe

This project concerns how optical illusion contributes to a fresh understanding of Wagner's work. I argue that, whereas artists and scientists in post- Industrial Revolution Europe tested the manipulatable nature of human vision, Wagner found in it a source of inspiration for his critical approach to the relationship between sight and sound. His use of offstage music often appeared under the dramatic pretext of supernatural scenes involving optical illusion. I suspect that this approach derived from his larger musical concerns during his creative process. I will travel to the National Wagner Archive to examine his manuscripts of Der fliegende Holländer. This grant will facilitate my archival work and enable me to work with Professor Anno Mungen, whose 2006 monograph BilderMusik dealt with optical technology in similar repertoire. He will broaden my understanding of optical illusion’s impact on music from the perspective of the traditions of German theatre in this context.

Project Title: Reducing Measurement Reactivity in Physical Activity Research

Measurement reactivity is a source of bias in digital assessment of physical activity (PA), though conditions that contribute to its effects are not well understood. This Short-Term Grant will facilitate a collaboration between Dr. Danielle Arigo, a U.S.-based PA researcher, and Dr. Laura König, a Junior Professor at the University of Bayreuth, to achieve 2 research aims: (1) To produce a manuscript comparing PA measurement reactivity across contexts and identifying predictors of reactivity; (2) To generate the project description for a new grant proposal, focused on testing methods for reducing PA measurement reactivity in distinct contexts. During the proposed visit, Drs. Arigo and König will also hold a workshop on digital assessment of weight-related behaviors such as PA. Thus, the work proposed for this Short-Term Grant will provide training opportunities to researchers at University of Bayreuth and promote a collaboration that will help to improve the accuracy of PA measurement.

Project Title: The Role of Reasons in the Ethics of Health Care Allocation

The aim of the project is to develop a new framework for the investigation of allocation issues in health-care. Any agent who makes a claim on health-care resources must provide reasons that support their claim. I propose that distributive justice in health-care resource allocation is therefore best seen as an attempt to maximize reason-based claims of agents on health-care resources. But ought we to make such priority-setting – often called ‘rationing’ – decisions? I propose that the answer to this query also depends on our account of the relevant reasons. In short, the most promising way to approach this area of applied ethics is to focus on the (normative practical) reasons that are relevant to our inquiry. This is a promising way also because in recent years there has been an upsurge in research on reasons. At the same time, this discussion has not made its way into medical ethics. This projects aims to fill this gap by fusing applied, normative and metaethics.

Project Title: Investigation of recombinant spider silk protein encapsulation to enhance upconversion implant biocompatibility and anti-microbial properties

Upconversion nanoparticles (UCN) are nanotransducer for near-infrared (NIR) to visible light, an important feature to breach the tissue depth penetration limitation of visible light. However, the application of UCN solution directly into tissue, limits its clinical translation. We have fabricated UCN based implants with great flexibility demonstrated in wireless photodynamic therapy (PDT) in mice model brain tumour. In order to enhance further translatability of UCN implant (reduce scarring, anti-inflammatory and anti-microbial) recombinant spider silk technology is being explored to coat the UCN implantable. Recombinant spider silk has been demonstrated to be an ideal material that can reduce scarring, inflammation and has anti-bacterial property. We will examine the suitable surface modification for both UCN implant and spider silk for the coating to happen and the durability of the recombinant spider silk, towards the course of PDT.

Project Title:  Distant Reading Modern Historiography: Three Case Studies

Historiography mirrors the narratives of polities. It evokes imagined spaces, assembles groups of agents, defines codes of conduct, and merges them into historical outlines that are meaningful for the self-concept of political entities. Although the connection between historiography and state/nation building is obvious, it has never been tackled from the perspective of large-scale, algorithm-based corpus analysis similar to the way in which, for example, Franco Moretti has applied “distant reading” to literary studies. During the proposed three-week collaboration in 2021, we plan to work on three test cases: a German/Latin work from the 17th century, textbooks from the 19th century, and a comprehensive list of Catholic historiographers from the early modern Holy Roman Empire. We plan to perform a computer-based analysis of (a) the geographic, (b) the prosopographical, and (c) the conceptual and narrative scope of our three data samples. Interested colleagues will be invited to participate.

Project Title: Determinants of phenological events in African savanna trees

In monsoonal, rain-limited climates the timing of phenological events such as fruit production, leaf deployment and leaf abscission determines not only the carbon exchange dynamics of ecosystems, but also the availability of food for animals. The intensity of seed production also varies greatly in intensity and frequency with uncertainty around controls of these dynamics. By using data that has been collected over seven seasons both inside and outside of a protected area, we intend to identify whether resource levels or environmental signals control synchronised reproduction through a state-space modelling approach that will allow us to model the resource status of plants, as well as interactions between climate and resource levels.

Project Title: Design and processing of novel heterogeneous catalytic nanocomposite fibers based on polymer derived ceramics approach

Lignocellulosic biomass which is an abundant, non-expensive and feasible (due to the non-competitive nature in the food chain) material is an excellent choice of replacement for fossil fuel and has wide application in medicinal chemistry. The development of novel catalytic reaction scheme concepts that mediates the conversion of lignocellulose derived alcohols to aromatic N-heterocycles (hydrogen generation/storage) is a challenge. In order to catalyze the corresponding reaction steps more efficiently and to withstand the strong basic conditions during the synthesis, novel catalysts have to be explored. Hence, the aim of this project is to design of a sustainable reusable heterogeneous catalysts based on transition metals, acknowledging the factors such as cost, selectivity, reusability and activity as well as the conservation of limited noble metal resources.

Project Title: Structural features of ion-conducting BaLaInO4 for electrochemical applications: Effect of acceptor and donor doping

In January 2021, Assistant Professor Maxim Vlasov stayed in Assistant Professor Mirijam Zobel's group of solid state chemistry in order to elucidate the structure of oxygen-ion, proton and lithium-ion conducting oxides, for instance BaLaInO4 featuring the Ruddlesden-Popper structure. For this, Mr. Vlasov and Ms. Zobel employed both powder X-ray diffraction and pair distribution function (PDF) analysis based on high energy X-ray scattering data from the state of the art PDF diffractometer in the Zobel laboratory. The combination of this structural insight into the short-range order complements previously obtained electrochemical performance data to ultimately reveal ion transport mechanisms in these materials. The ion-conducting Ruddlesden-Popper oxides were synthesized at the home institute of Mr. Vlasov, the esteemed Institute of High Temperature Electrochemistry in Ekaterinburg, Russia. This scientific cooperation is an extension of the established series of summer schools named Travelling Seminars in the topical field of nanoscale materials and large scale research facilities.

Project Title: Charge transfer mechanisms in light converting systems from Time-Dependent Density Functional Theory

We aim to investigate light converting mechanisms in both artificial and nature systems. Donor-acceptor materials that can be used in organic solar cells and bacteriochlorophyll complexes from photosynthetic bacteria will be studied using Time Dependent Density Functional Theory. An important aspect of our work is the use of approximations that are capable of correctly treating charge transfer excitations. We combine those with an appropriate treatment of intermolecular interactions and long-range dielectric screening coming from solvation effects. Our long-term aim is to contribute to the development of materials that can efficiently convert light to other useful forms of energy.

Project Title: Preference Rankings and Proportional Representation: Mismatches in Germany, 2005-2017

As with all proportional list systems, the German system is afflicted by a fundamental inconsistency known as the More-Preferred-Less-Seats-Paradox. Although this has been known to be a theoretical possibility for a long time, it has never been demonstrated empirically for Germany. We follow a method previously applied to studies of elections in Denmark (1973–2005) and The Netherlands (1982–1994) that reconstructs these preference rankings from opinion polling data. We use flash polls that contain “thermometer data” on party preferences conducted the week before polling day for the Federal Elections in 2005, 2009, 2013, and 2017. The main finding is that each of the elections has been afflicted by the paradox. Qualitatively, it is arguable that the occurrence of the paradox in 2005 and 2009 is relatively benign. But in 2013 and 2017 the paradox took on a different dimension. Firstly, in 2013 the liberal Freie Demokratische Partei (FDP) actually dropped out of parliament although being preferred over the leftwing party DIE LINKE, which was the so-called Condorcet-loser (or least-preferred party). DIE LINKE was the third largest faction in the Parliament and the official opposition. Then in 2017, the populist rightwing party, Alternative für Deutschland (AFD), received the third largest seat share although, as with DIE LINKE in the previous election, it was the Condorcet-loser and it too has become the official opposition. This suggests that the current system has the potential to distort the representation of voter preferences. We discuss the source of the paradox and the normative implications of these results by placing them in the context of representative and epistemic conceptions of democracy.

Photovoltaic materials are promising candidates for facilitating the transition from fossil fuels to renewable energy sources. Organic photovoltaics (OPV) have properties, such as being flexible and light weight that make them attractive for specialty applications. The efficiency of OPV depends on many factors, and one is the morphology of the material, which can be steered by electric fields.  Here we will do computer simulations of the formation of the films under control of electric fields, with the aim to be able to control the morphology in the production process of OPV in order to improve their efficiency.
